Hi Rick
Some great builds have been done with stretch bikes. always a way. have you considered a mount like a whizzer? One bent flat bar that supports from below and secures to the down tube and seat tube. If it is a long stretch, may not be your best option.

I've seen pictures where someone has mounted the motor diagonally on the seat post and the bottom tube of the frame. Are there any drawbacks of mounting it like this if it fits? or would turning the motor create more mounting problems

You can mount it anywhere you want that fits. As long as you have it fastened both at the front and rear mounts,and you can adapt the carb to make it level. those are the 2 critical things that you need.

Motormac is correct. Placement is not as critical as compared to making sure the motor is secured. It does vibrate ater all. And the carb needs to be level. Otherwise, fuel does not reach the combustion chamber efficiently if at at all.

The mounts are made out of Simpson Ties (construction ties) purchased from Home Depot. I also added an exhaust clamp to keep the tube from wanting to flatten out. Here is a photo of the finished mount. The bottom bracket is the smaller half of a chain tensioner.

I have found that the lower you get the motor the better drive chain clearence you will have. On the stretch frames that I have used (Micargi and Greenline). The rear frame rails are tight together. Kinda hard to explain. Where you would typically mount the rear brake and or fender (cross bar) is dropped way down in order to get the stretched look. That cross bar can be a problem. I'll try to post a picture of the rear frame rails.

Normally stretch cruisers have wider tires right? Can it work without the chain rubbing the tire with the same tires or would you need to switch to thinner tires?

I believe you are correct. Nice ride. We just began building these in St Pete Fl and I cant believe the response and how they turn heads. Fun stuff..
