I know this thread is from the summer, but thought I'd share my experience rather than start a new one. I just mounted some Continental tires from 2017. I had always heard five or six years is the maximum life (mounted or unmounted). I did raise this issue about the tires being four years old at thi...

My 170i has a stock exhuast (once replaced). Usually it's pretty loud when in motion, but when braking and the engine switches to idle, it gets a bit more quiet. In the past, the idle has been relatively loud, sometimes pretty high. Then the engine started having surging problems until finally it wo...

If that were me, I would toss them. I heard that scooter tires are only meant to last five years from the date of manufacture due to the rubber deterioration. In fact, in my other thread where my sister's dog bit my scooter tire and put a crack in the sidewall, I had to order a replacement from Scoo...

Tire is now replaced. By far, the hardest maintenance ever. It was nothing like what you see in the videos. I had to take the thing to my uncle who is a mechanic and it took both of us 40 minutes. Getting the tire onto the rim took lube, multiple tire irons, a crowbar, a mallet and both of us standi...

Great videos, scootERIK.

Seating the bead part is actually what has me most worried. I'll probably have to take it to a gas station with an air compressor and fill it there.

mukaiboston

Tires make me really nervous too and I wouldn't do it myself if my scooter were rideable and I didn't have to wait a month. The two parts that scare me are making sure the wheel doesn't fall off and making sure that air doesn't escape around the rim. For the first part, my rim actually is two parts....

mukaiboston

I should point out that I called around and no one has a 3.5 x 10 tire in stock. I was planning to swap both tires out in the spring with black Michelins to match but I'll just have to buy another whitewall Continental if I only want to mess with the rear wheel and get this thing back on the road. I...

Since the scooter currently needs to be towed, I lose nothing trying to do it myself. I read somewhere from a person who used to swap motorcycle tires frequently in the shop that they would remove the old tire in under a minute using bolt cutters to break the bead. If the tire is already shot, why w...

My sister's dog usually comes out to watch me work on the scooter and I've even run the scooter in front of him. Not sure if it's his male hormones kicking in or what (he just had his 2nd birthday I think), but he's gotten more aggressive lately. This weekend I was changing the oil and when I starte...

Try calling Smooth Automotive in Medford and ask to speak to Frank. https://www.yelp.com/biz/smooth-automotive-medford-2 Back when I lived in Somerville, I used to go to him when he first opened as Smooth Scooters. The reason it is a car shop now is because he had too many problems with people bring...

The fusebox is located under the front panel below the turn signal relay. It looks like a small box with all the fuses in a row. The 1A fuse protects the computer The 5A fuse protects the fuel pump and injector The 7.5A fuse protects the ignition wiring The 10A protects the engine management system'...

The scooter is now fixed. The temperature sensor was to blame. I was able to obtain a diagnostic tool to pull the fault codes off the engine and it flashed the code for "engine temperature sensor". I had checked that sensor with a multimeter and it had resistance that was within specs but ...

mukaiboston

I'm still trying to diagnose the rough idle and misfiring on my scooter. I finally was able to obtain the diagnostic tool, erased the scooter's memory and then started the scooter and let it run for a bit. Then I plugged the tool into the data port to pull the codes off the dashboard. The EMS light ...

mukaiboston

I'm not an electrician, but here is the basic rundown of what I've been doing. Each sensor will have some number of pins. One is a ground pin and the others could be data pins (marked as "output" on the diagrams) or power input pins (which delivers electricity to activate the sensor). You ...

mukaiboston

I'm having a hard time obtaining a diagnostic tool to pull the error codes out of the ECU. Someone told me I could jump the pins to get a read out. I'm thinking of using an LED or a multimeter, but I cannot do this if I don't know what pins to jump or what each pin does and the schematic is not in t...

mukaiboston

Successfully replaced the pump! However...that was not the problem! Scooter runs like crap just as before with the engine light coming on. I'm thinking the fuel injector has a problem then. The engine light is coming on before I touch the ignition. So the computer is detecting something is wrong wit...

mukaiboston

Dirt was maybe the wrong word. It's either deposits or sludge. I don't know. I've squeezed the filter with my fingers and whatever it is, it appears to be inside the mesh. It looks like a pocket of soft mesh that is heat sealed on all sides. It should be white though so the fact that it's black all ...

mukaiboston

Searching for help about the Buddy fuel pump is maddening. It seems almost no one (except DeeDee here) knows anything about the pump or replacing it. I've called Scooter Lounge, left a message on Scooter works, called the mechanic near me and they have no idea how to replace or remove the pump and e...

mukaiboston

Yup, that's why I haven't looked into this at all. I searched for fuel filter on here for years and nothing has ever come up. I had no clue it was part of the pump.

mukaiboston

One more thing for anyone who knows how to remove a fuel pump. I was researching this for cars and want to make sure I have this down: 1. Depressurize fuel lines by removing the fuel pump fuse from the fuse box under the front panel. 2. Start the ignition and run the scooter a few seconds. Instructi...

mukaiboston

Thanks DeeDee, I'll look into getting a fuel pump and see if that fixes the issue. I'll report back on what I see if I can get the old pump out of the tank. Hopefully, the eBay link you posted is good. I don't see any many places to get only the pump. I poked the filter with a straw while it was sti...

mukaiboston

I'm watching motorcycle maintenance videos online and from what I can see from similar bikes is that the fuel filter is built into the pump and not replaceable.

mukaiboston

This is the Buddy 170 pump. https://www.scooterdynasty.com/fuelpumpfor170igenuinebuddy.aspx As you can see from the photo I posted above. The bottom of my mesh doesn't look white like this. It looks like it is covered in black and silver sand. Any way to clean these things or replace just that part ...

mukaiboston

It hasn't been that hot lately until this week and the problems started before then. The problem with the hard starts started on cooler days so I thought it was just the drop in temperature. That pump doesn't look like mine at all and I don't think it is OEM. My pump is white and is available for $3...

mukaiboston

Iâ€™ve run fuel injector before and I use sea foam regularly. I heard those can also push the dirt further in if it doesnâ€™t come out. What I might do is just replace the fuel injector as a gamble and then have it towed to the shop if that doesnâ€™t work. Without the diagnosis cable, Iâ€™m going to...

mukaiboston

Can you load test the battery? The amperage might be too low. If it drops lower than 9v while starting, the battery is probably no good.

mukaiboston

Note: the Buddy 170 is fuel-injected so there is no carburator. A few weeks ago, I noticed my scooter was having a rough time cold starting. I would have to hit the ignition twice which seems unusual in summer weather when it should start right up. On Sunday, I was out and noticed the idle seemed un...

mukaiboston

Great. I pushed the belt as far down in the clutch as I could so there would be plenty of slack on the variator side. I've read that if you don't do this, you can tighten the variator onto the belt instead. Then I moved the belt around a few rotations to get the slack back on the clutch side and mak...

mukaiboston

Anyone have any advice for getting the belt around the clutch? I couldn't believe it took me and my sister pulling on it. I just couldn't have both hands pulling the clutch and fit the belt in with my fingers.

Looks so easy in youtube vids.

mukaiboston

Okay, I'm done! The pins on the variator tool were removeable. I went to the hardware store and got some smaller long screws and bolted them into where the pins went. As soon as that was done and on the variator, the nut came off easily with a breaker bar. I was surprised how easy it came off. Every...

mukaiboston

Variator tool came today but it does not fit in the holes. The pins are too large. I thought it was one standard size but I guess not.

mukaiboston

I'm doing a belt change on a Burgman today. I hate buyng a tool that only gets used every 14,000 miles. Same principle, a little different take. I'm holding the Burgman variator with3 L brackets and misc. hardware I had laying around. DeeDee, I read you aren't supposed to hold the fins like that be...

mukaiboston

So the method in the video didn't work. The belt came today and I tried to swap it out using this method and I couldn't fit it over the variatior so I'm going to have to remove the variatior completely. The belt that came looks almost identical to the belt in there. In fact, I'd say the belt in the ...

mukaiboston

On the belt youâ€™re measuring belt width, which wears down over time after being squeezed and pulled between the two sets of pulleys for thousands of miles. And looking for signs of cracking, errant threads, etc. I donâ€™t know the specs for the Buddy yet since I havenâ€™t had to do this myself bu...

mukaiboston

Belt and sliders shipped out from Scooterworks yesterday and should get here by Friday. Glad I paid for priority shipping. If the method in the video works, I'm going to try to do that to at least swap the belt out so that I don't have to worry about it anymore. I can work on rollers later after I s...

mukaiboston

I managed to get the CVT cover off after removing all the screws and banging on it to loosen it off. I'm not sure what I'm supposed to be looking for but I don't see any cracks or frayed edges or anything. I placed an order on Scooterworks for a new belt and some sliders so I'll contemplate whether ...

mukaiboston

Thanks for the insights. Hopefully I can at least get the CVT cover off to look around. I know we've got a bunch of DIY people here but I have to admit sometimes that I am not mechanically inclined and risk damaging the scooter just because I don't know what I am doing. Belt currently has around 8k ...

mukaiboston

Usually I take my CVT in yearly to get inspected, but I'm thinking of doing it myself if I can due to the pandemic. Main problem is that I lack tools. Is it true you don't need an impact wrench and does this trick work for the buddy? Basically, the guy in the video squeezes the clutch plates togethe...

mukaiboston

Wow, just found out Modern Classics in Washington, DC is closed! I need my yearly checkup done (mainly valve adjustment and check belt and brakes).

College Scooters is far. Anyone know of a closer place? I used to go to La Moto but their new management won't service Genuine.

mukaiboston

The bike has nearly 25,000mi on it. I can turn the wheel when the scooter is off. I thought about the sticking throttle cable, but the fact that simply restarting the engine fixes it ruled that out. I don't know about the clutch then. The scooter accelerates very rapidly. On a carburated engine I'm ...

mukaiboston

Thanks. I actually had the CVT inspected when I did the valve adjustment in april. The replaces the rollers and inspected the belt as well.

mukaiboston

A couple of times when starting my scooter and accelerating forward, the engine has failed to return to idle. It basically sounds like it is still in 1st gear trying to move forward and I have to keep the brakes down to prevent it from moving forward. The first time this happened was over a month ag...

mukaiboston

It was Modern Classics, but not Gerry though as he is in Italy. I'm sure they are competent. I just never heard of a whitewall tire being two fused pieces of rubber and then exploding. The white part looks painted on to me.

mukaiboston

My normal mechanic had a change of ownership (long story, but apparently mechanics were shooting up and stuff and Piaggio threatened to revoke their license unless they did a 100% staff turnover in ten days). Anyway.......the new management won't service Genuine scooters so I now have to go to the d...

mukaiboston

If you are talking grabbing then yes. Less bad during colder weather. Hot weather and rain make it pretty scary. And it usually eases after riding for ten minutes or so. I need to have my tire changed and will ask them to replace the entire mechanism at this point. That whole assembly was taken apar...

mukaiboston

I've taken it out quite a few times now and it runs perfectly. I have zero clue what was wrong. I'm wondering if it had anything to do with me switching from regular to premium a couple nights before it stalled the first time. There are other posts on here about how switching to BP gas caused stalli...

mukaiboston

I'm not an electrician, however I do notice all the lights stay on when the engine would cut out. Either power is getting cut to one specific area or its a fuel delivery issue.

mukaiboston

Sooo...after not starting it for four days as I took the seat of and started pushing and prodding every wire and tube and connection I could find on the engine, last night I started it and it ran perfectly and did not die despite me jumping on the seat and taking it on and off the center stand multi...

mukaiboston

No, in fact I find I have to do it if the temperature outside drastically changes so I wouldn't worry about it.

mukaiboston

I also want to point out that I do track my mileage and itâ€™s has been perfect up to this point. Iâ€™m averaging 80+ mpg.

So whatever is happening is a quick, sudden change.
