would this bike work? - motor mount - pics
would theis bike in the link work? the only reason i would think it would not is because of the bottom tube. it is really thick.

i had a similar frame....very tight fit...needed to alter the intake & carb.
didn't do it. I like the frame style.

i agree with srdavo...nice frame but it looks like a tight and high fit, could be tough to fabricate a front mount that lets it sit right.

it also looks like the seat tube is to big.

about that...my whole frame is 35mm & i thought i was gonna have problems. but, even tho the mounts don't seat all the way, the studs (very tightly) clear the tubing and the brackets fit on enough for the nuts. the brackets formed themselves to the bigger tubing & the engine-mounting is rock-solid.

One way you can mount to different sized tubes is to make a steel plate drilled to fit the motor mount studs and another set of holes to fit a vibration damping u-bolt that fits the tube. I've done this on two bikes without any problems.
Here's a pic of an 80cc mounted that way.

Here's a couple of different kinds of cushioned u-bolts available in different sizes at McMaster-Carr

I like Rusty's better than the one I used. 8) Two u-bolts is a lot sturdier than one.
