Modern Buddy

Do you have the air filter installed, the snorkel and everything sealed up tight on the carburetor? Some systems require it in order to run right. That was good you raised the clip to the third groove. Raising the clip leans out the 1/4- 3/4 throttle. You can try going to the 4th clip up and see if ...

Find a small electric guitar string and poke out the jets.

Have you messed with the needle height?

Last question, did you try riding and pulling out the choke? Did that make things better or worse?

Have you checked for leaks at the exhaust? What about at the fly side engine seal behind the flywheel? Leaky head? Have you removed any of the head components?

One way you can enrichen it is to pull the choke. It’s not a permanent solution but it will help when you need it.

With that style box/housing with no oil pump you could just premix the oil into the gas and call it good. Someone has definitely stole parts before selling it to your friend. The electric starter is gone, a different flywheel is installed. Maybe the wrong electrical junction box? If you remove the c...

Pulled the stator and had no continuity between the coils so I eventually found where one of the copper windings had snapped. Soldered it as best I could and then reinstalled everything and I had lights. To answer my initial question resistance was super low through the blue and black wires. Less th...

Can anyone with a Stella 4T get me a resistance value of the blue wire coming off the stator? Right now I get no continuity period.

Im trying to diagnose a bad regulator/ rectifier and think the problem might be at the stator instead.

Thanks everyone.

To answer your question, yes going to a mechanic to install the tire is purely out of convenience. Do it once and you’ll realize an hour later that a few bucks to a mechanic is worth so much more than what you spent on spoons, rim protectors, bead buddies with a lot less cursing/bloody knuckles/ w...

Call your local scooter shop and see if they’ll change the tire quicker if you just bring the wheel in. 10 minute job if they have a tire machine. Then you re-install. If that doesnt work, buy a new tire and take new and old to an independent motorcycle shop. Usually cash will expedite the process...

I’d say pickup a used 250 if the finances allow. Cheaper but still the same technology and HP to get you up to speed/ out of the way. That is unless you are physically limited and need something smaller/ lighter. In that case, I would buy the Hooligan since it will be a low miles, fun scoot.

If you have any Harbor Freight coupons, they have a decent ultrasonic cleaner. Bathe and poke with the smallest electric guitar string you can find. Might take a while but its possible.

I may be able to help sometime midweek. I’m up in Oceanside.

There’s plenty of used Buddy’s on Craigslist in LA. Make the drive down and you can take your pick. Or, take the train down, buy the one you want and ride your new scoot home.

So did the piston shatter causing the lockup? Pics now that you have things disassembled.

On the lip you could also JB weld the hell out of it. That way you dont warp anything. Again pics!!

Ouch! Sorry to hear about the cracks in the casing. Are they really cracks or just casting marks? Sadly you cant just buy one half of an engine case. The two are mated together from the factory. Replacement cases are very pricey. Might be better to find an aluminum welder. How was the top end? You s...

For the bottom end you definitely have to disassemble it to see what youre dealing with.

What specific problems are you dealing with to make you focus on the lower end?

Whats the condition of the battery? Charged? Dead?

I just wanted to wrap up this thread with an update. SIP was sadly back ordered on a lot of essential parts but I found Scooterworks had a replacement crank for double the price of SIP (ouch) and whatever else was missing. Couldn’t find any other US shops with parts but I’m happy with SIP and SW...

Dooglas,

Thanks for the reply.

The search continues!

Friends Stella 4T crapped out with 2K miles. I cant find any sources for a replacement crank. Other than the 200 motor swap from SIP does anyone have any recommendations? I’m still waiting to hear from Vespa Motorsports.

Thanks all.

Yea I figured the loom would be different as far as the injection system goes but I wasnt sure about the oil cooler or how the engine case mounts to the bike frame. I definitely know the fuel pump and fuel pressure sensor would need their own wiring and power source but I wasnt sure about anything e...

Does anyone know if its possible? A buddy of mine just blew up his engine but has a lead on a salvaged 170i engine. I know the 170i engine is injected and has the oil cooler up forward but other than that is there anything else that different that would not allow an engine swap?

Thanks everyone!

When it was in perfect shape it would cruise 60-65. Stock 125 set up but Prima exhaust added.

The valves were so bad it was having problems starting so the Buddy went into storage and my friend rode his other scoot.

I'm going to check the air filter tomorrow. Weights and belts after that

Ok. Again adjusted them to .08mm so I felt a slight drag on the feeler gauge and I got it up to 52 this time.

Asked my friend how long ago he changed his belt/ rollers and it's been a few years. I'm going to dive into that next.

Thanks for the response.

I just adjusted the valves on my friends 08 Buddy 125 to .08mm. Piston was moved to top dead center per the 3 holes and the marks on the cam gear. After buttoning everything up the bike started fine, accelerated fine but wouldn't go past 50. It didn't even feel like it had more to give. I'm waiting ...

Ok i'm on it. I'll take pictures of what I find. Can anyone tell me how to post pictures so you guys can point out anything else?

Ok thanks for the service manual. I'll get the rear wheel off and look at the bearings. I'll also look for gear oil. Would bad bearings be the main problem as to why my friend can't go faster than 30? I just though bearings were for alignment and support. Should I check elsewhere? Dirty carb jets? M...

I didnt notice any unusual wobbling in the rear tire. I'm not sure about the gear oil but I'll check tomorrow. What does it take to change out the rear wheel bearing? The shop did not do a compression check. What PSI should the compression read? Does anyone know if there's a Genuine service manual/ ...

http://www.youtube.com/watch?v=hadcan63 ... e=youtu.be for a video of the back tire spinning and does anyone know how to post a video? I can't get a 90kb picture to upload

My friend has a 2008 Buddy 125 that he rides non stop. An average day for him is usually around 100 miles. He recently has been having problems with his scooter going faster than 30 mph and just got a ticket for going too slow. All scheduled maintenance has been done on time. Fluids, spark plug, fil...
