Problems

I've got a schwinn cruiser with the 80cc Raw Motor which I've owned for 2 weeks now. I've already replaced the throttle(plastic piece broke that holds the cable) and cable(just because)and readjusted everything. But literally everyday there is something going wrong with this thing. Carb leaks, chain tensioner won't stay put(which of course kicks the chain at whatever speed I might be going), yesterday I blew a spoke and after looking at the wheel its warped and upon looking even closer the engine mounts are half broke! AGHHH! Any help would be appreciated. Are there any kits to replace all of these crap parts I have? As far as I'm concerned the only good things I have are a bike(minus rear wheel now), a motor, a gas tank, and nice Kawasaki motorcycle throttle. Everthing else I am questioning. Has annyone else had any of these problems?

Don't feel like the "Lone Ranger" with all the problems. These kits can be a pain. Once you figure out what works and what don't, how to install with some insight to what to be aware of...it will work fine. Read around....plenty of trouble shooting tips on here.

Oh boy, sounds like you are having fun. Motor mounts breaking? What part are you talking about? You have to make sure the motor is sitting properly in the bikes frame. You can't have a sloppy fit and expect the mounts to pull it in place. That just puts an unnecessary strain on the mounts.
The chain is a problem many have, including myself. I had to get a new rear wheel on my very first try at starting the bike. I ended up getting rid of that stupid chain tensioner and was able to cut my chain to the proper length. Others drill a small hole in the chain stay and screw the bracket to the frame to stop it from swinging into the spokes.
I think most carbs leak but that is why we always turn the gas off when parked. You could have a look at your float adjustment but I'd worry about getting the bike running first.
I wish you could post a few pics of that "broken mount" and I hope it's not the engine block that is broke.

^^^^
Its not block, engine runs fine. its the bolt on the right side that holds the bracket together, I would rather replace the whole mount and a lot of other parts because I know the parts that came with the kit suck. I was thinking of yaking some links out and forgoing the the tensioner pulley, the chain is already stretched. The screw idea seems more simple but might effect the integrity? Anyways, what I'm really fishing for is, what are the best parts and who sells them. I don't want replacement or OEMs of what I already have(which suck). Especially: Wheels & Engine mounts or even a whole new install kit(minus motor)...whats the best? I didn't build this bike but I wish I had, now I rebuild her rather than throw her in the compacter....

sickbikeparts sells a kit with all the studs as well as other "goodies".

Read around the forums and you find a lot of good info.

Ok, I've found a kit that replaces all the bolts and mount. I'm really having trouble finding information on wheels. I've read post after post and still nobody talks about rear wheel specifics and the hub/spoke bracket thing is there another option?. I just need to be pointed in the right direction...dead ends suck..again any help is much appreciated

sorry to hear Crotch that you are having so many issues. Dont take offense but my guess it is your skills at making this motor work for you and your bike. I never even knew it was possible to mount a motor on a bicycle until about a month ago and I was doing a google search and accidentally found one. I got both my kits from Bikeberry and my first build took me about 7-9 hours and my 2nd only took 4 hours.

The only issue I had was on my first build I dropped the motor off the bike (clumsy) and I broke the spark plug boot , so I just hard wired it to the plug, and then my chain broke due to an alignment issue. But got those 2 things fixed and off I went , I put over 60 miles on my first build and they have been trouble free.

But also I have alot of experience with small engines and welding , so If something dont work I will just weld it into place or use a bigger hammer to make it work. LOL

But like was stated earlier try to read alot and educate yourself on the in's and outs of these moters and all the stuff that goes with them, I personally do not feel any of the parts are junk that came with my kit, I didn't pay top dollar so I feel I got a really good bargain for my money, and both of my builds work as well as I can expect them too.

good luck in the future at getting your MB to run and be trouble free.

I wish I built this bike myself, I bought it complete...I'm pretty mechanically inclined. I've taken apart everything from a 350V8 to a 35cc tanaka motor. I'm not asking really for the how-to's, I just want to know where to get better parts from, all of the ads on this site only have oem replacement parts which I don't want. Seriously any links to any parts sites you know of. If they sell a good product and you or somebody you know uses it let me know. Thanks everyone!

Crotchrocket,
Not sure what problems you're having with the rear wheel/sprocket or why you want to replace the wheel. Did the tensioner get into the spokes? That's a common problem and can be fixed easily with a self tapping screw run through the tensioner bracket into the chain stay. It will not compromise the strength of the frame but will save your spokes and rims. Make sure the tensioner wheel is aligned before installing the screw ( I use a 10/32 allen head cap screw and nut). Most tensioner brackets will require a slight twist to get the wheel properly aligned with the chain/sprockets.
If you're having trouble with the way the sprocket attaches to the rear wheel and would like to do away with the rubber discs and the squeeze method here is a link to one of our bike friends who builds a sprocket/hub adapter that replaces the kit supplied 'rag joint' method. MANIC Mechanic Parts.htm Hang in there, don't give up and you'll be rewarded for your efforts eventually. Keep asking questions here. We're here to help.
