Well I had talked about it and finally bit the bullet. Bought a new 450r dasa and modded it to fit my hybrid. Didn't care for the yzf version being that its so much longer.
Special Thanks to
Jakey Products. for some amazing welds.
Also added a couple spring tabs although they are not totally neccessary. let me know what you guys think.

The exhause looks really bad ***, it looks like it was made for it! What did you have to do exactly to make it fit?

Thanks,
Mike

I'm going to take some actual clean pics later tonight when I get home from work. It makes the bike look haggered, but at least its getting ridden.
The inner diameter of a yzf, and crf/trx pipe are identical however the outer lip where it slides in to the head is about 1mm larger in diamter on the trx. So I very carefully drum sanded that down and polished it. The radius at the head pipe is a 180 degrees on the yamaha so we had to rebuild the head pipe, a few cuts here a twist or two and some damn good welds and it came out beautiful. He also built me a new intake adapter to go between the cr500 boot and my carb. I'll take some pics of that tonight again, I would have never imagined it would come out as good as it did. On the exhaust we also took off the old lower trx mount and built a new one so it could retain the lower mount on the subframe which most of us never use.
If someone else is running a lsr frame and a yzf motor I'm sure it could be duplicated for a small fee.
