Issues with my first installation

eugesd · #1 06-06-2009, 11:46 PM

Well, first i tried to mount the engine directly but the gear changer was causing it to slant so every time i tried to pedal the chain would get stuck, however i didn't realize that it was the slant of the engine so i removed a chain link and made it VERY tight. The chain then broke and i had to find the small pieces of the master link on the ground. So then i decided to try a different method by raising the engine higher and raise the front mount plate above the frame and drilling a hole through the frame then adding a bolt through the hole however now the chain would get stuck and the engine would start shaking, then the chain would jump off the tire sprocket and get stuck in between the spokes and the chain.

Also i cant accelerate the engine, twisting the handle does nothing, am i twisting hard enough, it only moves about < than a inch. I don't want to break it since i am putting a bit of force.

So all of this has stressed me quiet a bit, please help me out i just want to be able to

my bike

throttles put togther wrong ( I did that too ).. and your rear sprocket isn't completly true I don't think.... don't try to run it like that, you'll break somthing.. I tried to just fire mine off knowing somthing was amiss, and put the chain tensioner thru the spokes of my back wheel.. now due to cost's of that repair, I'v mounted in a diffrent bike

"put the chain tensioner thru the spokes of my back wheel"
what do you mean?

Because his sprocket wasn't true, when he fired the motor up, the chain put too much stress on the tensioner and pulled it into the spokes, which messed up his rear wheel.

Remove the front changer you won't need it. With it off you can lower the back of the motor a little to fix the chain length. Just put the chain on the middle sprocket with your fingers. Wrap the motor chain all the way around the rear sprocket and see if it fits well or kinda rises up on the teeth. If it does dress the sides and tips of the sprocket with a file till it fits right. Make sure the closed end of the master link clip points the way the chain is rotating. Towards the engine when it's on the top. Look in the carb where the slide drops in. There's a nub in there you have to line up the slot in the slide with it. GL

First all slow down, relax. Read some threads. Your problems are not unique.

Junster nailed it. Remove the front derailleur. It's just not necessary. The engine should fit and sit with carb relatively level to the plane of your garage floor. While I revile the bolt-on sprocket and distasteful left chain and tensioner, they can be made to work. Plenty of posts and pictures to view. Getting it eyeball straight is important.

Location matters because there just might be someone in your area who can help.

yup.. if you rush the rear sprocket, it'll never spin true.. when I put it on my new wheel/ bike I took my time, spun it several times while installing, making sure it was true.. I removed both derailures from the bike.. seized up anyway. cut the old rusted/ seized chain off with bolt cutters, along with the seized up derailur cables and ran a straight 1/2X1/8" bike chain in 2 sprockets that it fit without shortening..

You wrote: "the gear changer was causing it to slant.." so I assume you meant the derailleur on the front (crank) chainrings.
