Mounting Help!

cruiserdude · #1 (**permalink**) 03-07-2009, 12:21 PM

Ok, well i came to just another problem with my motor! My Mounting with the U Bolts did not hold the engine right, so i just decided to Drill thru my frame..i did that alright. Now that the engine is sitting straight down my tube, I run into the problem where my drive chain is touching my tire while resting on my Back tire Sprocket! Ive done everything, Ive added Washers to the engine, Ive pulled the engine to the left as much as i could, but it still wouldnt be straight with the sprocket. Im not sure the back Sprocket can move because theres a wedge on the outside, meaning if the sprocket moves a bit out, it will slide off. When i had the U bolt on i had the motor leaning about 1 inch to its side, but the motor was unstable that it would shake on a 30 min. ride

Can you guys give me some advanced techniques that might help (including welding techniques).

Do you have pics? Is it a "normal" bike? is the tire just too fat? I had that problem when I put on a nice big fat mountain bike tire. The rubber got worn away in a month until I could see the belts.Is your sprocket the "dished" one or is it flat? The dished ones can be turned to get the teeth outwards.

ok i have a 7 speed Greenline beach cruiser bike, not sure how big the tire is but its filled to 40psi. My sprocket is just a flat 9 hole sprocket..the teeth seems normally equal all around...i have one big rubber circle on the outside of the spokes, one on the inside of the spokes.

Ive gotten to the point where im gonna hire someone to weld me some arms that will lean it out a bit. I just dont understand why they dont inform about this problem in any of the instructions.

Your just frustrated right now, there are thousands of us that don't seem to have your problem. I will search for a pic of your bike so that I can see the frame and hopefully, someone else will pipe in with thoughts. Just hang in there, these things always get solved.

I guess this is your bike. Having never worked on a cruiser style bike , I can't help you much but the frame seems normal.
I wish you luck and please don't give up, someone will help you.

thank you Toytime for the picture, Since i am at work i am not able to upload a picture of my bike, but that is the bike i have excluding all the flames. I AM frustrated, mostly because i cut half of my fender thinking it would solve the problem, but i dont care about that as long as i get a mounting technique that works.

If anyone has any suggestions with this kind of bike, let me know! thanks!

Here's a pic of a "dished" sprocket. It can be flipped around to bring the chain in closer or farther away. Do you think this would be enough to get that chain away from the tire?

you acn also put some washers behind the sprocket before the first part of the rag joint to move the sprocket out a little

It's ok if the chain rubs the tire a little.
