Actually viney266, I did take them to two different shops. Youngstown Cycle Supply, and Cycle Motion in Unity, OH. One shop flat out told me no way, they wouldn't touch it (YCS). Another said it didn't fit on their machine, so they put them on with irons. Turned out I used the wrong size tire width ...

I had so much trouble getting someone to mount the tires I decided to give up and sell the wheels. I'm just going to stick with the SIP performer tires and TT wheels. No shops I went to were even able to remove the tires let alone mount the new ones! I wrestled around trying to mount by hand watchin...

I hope you post pictures. I'm looking into doing the same.

Take care of yourself and recover! That's scary stuff!

Johnny O

Thanks for all the great ideas. I've always been curious, what are the consequences of running too much oil? In order to generate power on the power stroke the piston needs to be able to move in a downward motion following combustion in the cylinder head. A extremely high oil level (think full cran...

I'm pretty determined to hash out the fit of the bitubo before Amerivespa this year. I'll post it as soon as I get started. I'm going to be busy for a while so hopefully I'll get it done by May.

In my mind there will be welding.

A heavy lean to the right with the cap off should work. That or just pick up the front end high enough.

A stator is toast once the insulating resin breaks down and the stator shorts to ground. Manufacturing defect is the first failure mechanism that comes to mind. High temperatures also can cause premature failure of the insulation around the windings. Mileage really only indicates age if you are assu...

I was gonna say.. the plug on the left looks like a 2 t plug. Did the smaller size of your stella spanner wrench fit that plug that you pulled out? If so, did then wrench go down the plug hole ok? That was original issue. Inquires minds want to know My guess, I think a 2T tool kit got put into your...

Johnny O

The 2T runs this:

NGK - B6ES:
Thread diameter: 14mm
Thread reach: 19mm
Seat type: flat
Hex size: 21mm
Tip configuration: non projected
Construction: Standard construction
Terminal type: Removable

I think you got the wrong plug.

Johnny O

According to the manual the following is the direct replacement: Champion - RG4HC; MICO BOSCH - UHR3CC According to sparkplugcrossreference.com: http://www.sparkplug-crossreference.com/convert/CHAMP_PN/RG4HC Details about Champion RG4HC: Thread diameter: 10mm Thread reach: 19mm Seat type: flat Hex s...

Once you remove the black plastic cover you'll have a much easier go of things. The cover holds the little rubber insert that is in your way.

Johnny O

az_slynch.....how do you go about determining what size / brand bearings you needed? I see a lot of complaints on the Indian bearings, but I rarely see anyone discuss where or how to get replacements? Could you maybe teach me to fish and explain how you came about finding the replacements? As my pro...

I'm going to have to play with mounting for the BITUBO Sport shocks: http://www.sip-scootershop.com/files/catalogue/index.html#/629 For me the biggest factor is getting some adjustability for when I have my wife riding with me. Spring pre-load should help a lot. The upper mount in the rear will be f...

Although we're seeing some nice temps this week, I'm leaving Stella in the garage until April at a minimum. Until then I want to start getting ready for some more mods. That got me thinking.....What mods are you all planning on getting done before Spring riding season starts? Here's my short list: -...

Johnny O

There is a fender. I made it out of the airbox and mudguard. Agreed. If you cut off the top of the air box and reattach the bottom as BigDaddy has shown its technically no different. My air filter is actually more exposed being on the side. If you include an elbow from the carb its out of the line ...

Johnny O

Looks exactly like the way I did mine. Nice Work!

Johnny O

So I spent some time pondering this question today and I came up with my own explanation as to why I believe installing a 2-stroke exhaust on the 4t will work, but with diminishing returns. The 2-stroke exhaust uses the initial shock wave of the gas exiting the cylinder on the down stroke to reflec...

Maybe this will help you:

We had some discussion going for a while regarding the 22mm kit with performance exhaust. Granted both of us are not running the 165 (yet), but might give you a stepping off point:

Johnny O

Good call about the choke spring mine behaves the same......I didn't think to try that. Thanks for the info!

Johnny O

Thanks for clearing that up.....I wasn't sure. Do you have the part number and a linky to where you ordered the 102 Main from? I'm looking for a simple winter project to do and that looks like a good one. I'm also wondering how many turns out you think you have on that screw? If I recall, 2.5 turns ...

Johnny O

If you grab the rear spring/damper assembly can you wiggle it? Is it loose at the upper mount?

Johnny O

I forgot about responding to my earlier post......Scooterworks never responded to me. I'm not going to try contacting them again. I'm not that worried about it since I don't have the product. My guess would be they don't have to get testing on a replacement part like that.

Johnny O

Please don't take any offense to this, but if you want to expand your knowledge base and plan on doing a lot of work in the future pick up a Haynes manual: http://www.haynes.com/products/productID/501 This will cover 99% of what you are going to need to do. For less than 50 dollars you can be assure...

I'm going to guess that it's because the GPS speedometer is set to kilometers per hour, since KPH is illuminated. That'd be more like 41mph. I suspect that a 4T couldn't hit 67mph in freefall.

Good eye. Yea, I'd have to invest in that type of plug! It'd be cheaper than a new top end!

Johnny O

you might need to change your title of this post to "Running too Lean?". Check your plug and make sure its not burning up.

Johnny O

How old is that plug? There could be lots of things that play into that. Carb setting seem most obvious, but you could have some oil blow-by into the cylinder causing pre-mature fouling. MPG changes aren't indicative of faulty plugs rather changes in your carbs ability to manage air-fuel ratio. Too ...

I don't have any stations near me that have ethanol free gas. Try this site for locations near you: http://pure-gas.org/ Keep searching on this topic in the forum.

According to the service manual 0.7-0.8 mm. Unless you are looking for what denso might recommend. Back when I noodled with import autos in the 90's I remember contacting Denso about gapping. I recall them e-mailing me that their plugs don't need gapped when purchased for specific applications. This...

Plenty of discussion on tubeless rims here. (I don't want to be THAT GUY, but search function ;) ) http://www.modernbuddy.com/forum/viewtopic.php?t=27034&highlight=tubeless I have the SIP tubeless rims with vee rubber tires. Worth every penny. No, you're not being "that guy", I've jus...

I work in Engineering and materials for my day to day job. IMO, you could have fatal flaws in both types of construction types be it steel or cast one piece wheels. I would suspect all flaws would be associated to manufacturing type defects. For example, in a cast wheel you could have a bad casting ...

Johnny O

Idle screw is on the side. That is the one you can adjust easily with everything assembled. The air screw is likely what you're looking for...its under the intake venturi in front of the carb. You should be able to get a aftermarket air screw that can be adjusted without having to remove the carb. I...

I use a Kryptonite bike lock through the front wheel. Similarly, I use a 10' lg coated cable I found at Lowes. It has a big loop on both ends and I bought a masterlock to lockup. Weave it in-between critical parts and good to go. Since I garage my scoot I typically don't use this. However, I have c...

Johnny O

Make sure you are getting Air/Spark/Fuel and go from there.

Johnny O

Thanks! I think that covers it!

Johnny O

UPDATE,

Yea I'm guessing its part number 17 on jimmbomb's post above..sorry I didn't read back

Yea, like stated in that post, if you are out of warranty phase should be a pretty easy swap out.

Johnny O

After some thinking and looking at Page 108 of the service manual, I believe the part in question is the "inner lever" shown on figure D and E of the service manual pg 108. Can anyone confirm this? I could see that this could be a wear item. Now the next question, if you want to replace it...

Johnny O

Where did you get the part from? Part# available? It might be safe to assume this part is faulty due to bad casting or manufacturing process. Anyone suggest or agree with a proactive replacement at this point? I'd consider it if we are all seeing the problem. In which case I'll do a DIY post to avoi...

The 2.10 SIP rims fit great as most of us here will attest. I don't know what tire fitment will work on the AUTO but some 100/90-10 tires will NOT fit the 4T. I inquired SIP about this and they informed me the correct tire is the 3.50-10. I also have almost zero run out on my 4T. I investigated this...

Johnny O

A brand new machine should run true. What you're describing sounds like hub run-out is bad. I'm not sure how that would work on the Auto, but on the 4T there is a big nut and cotter pin used to hold the hub on to the drive shaft. I'd guess the Auto is the same. I've never seen this so hopefully othe...

@ Matt Tipper, First off congrats on the trip across the US! So glad you had a good trip and completed it mostly unscathed! I wanted to meet you when you passed outside Youngstown Ohio but I was out of town when you came through. Since its in the general taste of this post regarding reliability of t...

I installed the Polini (Mikuni) 22mm kit along with this K&N Filter. I'm not a fan of the UNI: http://www.powersportsplace.com/parts/knn-rc-0840 It fits directly to the mikuni carb and doesn't interfere too much with the ignition pack. in the pic you kept the stock elbow, so it turns into that s...

Sorry I hijacked the thread with tire talk.....yes, I have the Heideinau K61's 100/90 - 10 and they rubbed bad. I tried all the quick fixes online; shaving the tread, grinding the oil filter cover, spacers. The spacers worked until I hit some hard turns on a warm day and the tires swelled up and sta...

Johnny O

Nice pics....yea thats exactly how I did mine too.

Johnny O

What I ended up doing was chopping up the air box in order to utilize the bottom of the box as a "mudguard". If you have a Dremel or other multi-tool its pretty easy. I also removed all the emissions crap when I did this plugging the gas vent with vacuum plug. You'll have to take the rear ...

Just wondering if any of you ever experienced a blowout on a tubeless? How about the tubed stock tires? How did the bike handle? I notice the Stella seems pretty heavy in the rear and my wife likes to ride pillion adding additional load (sorry dear). Was wondering how I would expect the bike to hand...

Johnny O

So I'd just like to get a little clarification.... The SIP tubeless Tire Wheel combos do or do not rub on the stock Stella 4T? I do realize the tire size will make a difference in that answer. I don't have any safety concerns with adding a washer spacer, I'd just rather not do it. I worry that I wou...

Johnny O

Correct ArgonV, you don't. I forgot. Thanks for setting me straight. I took a second look at the wiring diagram and a bad AC/DC regulator, magneto or bad connection to the regulator magneto might be an issue. If you have a service manual you can follow steps on page 33 and 34 to troubleshoot. You'll...
