New GY6 200cc Scrappy engine...NEED HELP!! By shizzaw (Read 8,253 times)

[shizzaw]

Hey guys! I have a huge problem here. After some serious problem checking, I decided to just order the 200cc GY6 motor from Scrappy for my 2008 JMSTAR Stealth. The engine came today and everything looks perfect.......until we tried to fit the rear wheel back onto the axle. The wheel makes contact awkwardly with the case and we found the wheel to be too small for the wheel molding on the engine case itself. The diameter of the inner rim housing is 4 5/8" and housing on the engine is 5 1/4". Please see pictures. The rim is too small. Does anyone have a solution or know of where I can get a rim to fit this new engine. I have searched online to no avail. Thank you for the help!! The tire is a 4.00-12 and it is a longcase.

IMPORTANT: RESIZE YOUR PICS TO 640X480 and they will be much easier to read! Rich

Thank you,

I would contact Scrappy. They have plenty of wheels listed on their site. I'm sure they'll have one that could fit. You could also contact one of our other banner venders, too, like:
www.partsforscooters.com/Wheel_Rim_Set_100-69?sc=9&category=383

That's a start, I'm sure there are many more out there.

That's a crock isn't it? They push those "upgrade' engines and make them sound like plug and play when they're far from it. They usually fit the 16" jobs like the Pathfinder and may have disc brakes when yours doesn't. This happens all the time so don't feel bad. The 200cc sonds tasty but if I were you I send it back and get one suited for your bike. The power increase won't be noticeable and you'll be months getting it going if at all. JMO, Rich

slow down , did you forget the spacer . I'm sure there is a spacer to mount the rear wheel . Please post pics of all parts laid out nice and neat let me take a look at it . If you have a calipor be ready to take measurements .

Yup the rear rim requires a spacer to install the wheel.

I agree with Bashan.. you may be able to rig some spacer so that engine will work.. but it isn't the correct engine. Those are for 16" wheels .

You may also find the axle is the wrong length also...

Sprocket , its a 12" wheel it seems to be a problem with width .
Ok I see the engine is for a 16"wheel .

I don't even think standard rear brakes will even fit on that engine.. what is the Pin to Pin distance?

[shizzaw]

Hey fellas, thank you all for the replies. I'll start from the top. I did try to contact Scrappy....just waiting for a reply back. I definately was not expecting to see the problems I did when I ordered the engine, but nonetheless....I need it to work. The spacer is not the problem and the pin length is exactly the same as the engine I just took out. The problem is the hub on the wheel is too small. I went to the local scooter shop here in Hawaii and they showed me a 13" wheel with a large hub. This is exactly what I need. The problem.....it was for a drum brake....not disc. Here on the island, parts are hard to come by because nearly all scooters are 50cc. So they are digging for me. The hub on my current wheel is 4 5/8" as indicated in the pictures above. I need a 12-13" wheel with a large hub (5.118") as shown by the graphic below. I have been searching high and low and they are difficult to find. Anybody know where I can get one? Finding them in stock is difficult.

drum brakes are just fine on a 150/200 cc scooter. All the rear brake is for is to keep the back end from sliding out. All your braking power should be on the front wheel anyway. If you can find a drum set up local go for it. I have a 180 cc 1983 riva with drum and it is every bit as good the 2008 150cc with the disk brake. If you had a big fast and heavy bike it might be a little different/

try here..787-830-3730..they might have the wheel you are looking for.

[sprocket]

It is NOT the pin length it is the distance between the pins. I don't think you can use a standard drum type rear brake shoe on that engine and wheel combination.

The 13"wheel uses a brake shoe that is 125mm or 4.9 inches in diameter, so that may fit your engine

That engine is not for a 16" wheel. That's the same engine I have and my 13" wheel fit just fine.
