Wow you weren't playing around you got that motor together fast and going. Good stuff sounds like a blast! I agree unless your building a drag bike, keep a stock length swing arm, way more fun. Less traction issues. I cant wait to finish my 7 mil
I had a similar issue last year with my 35 pwks on my 421. I dropped the pilot size quite a bit and it helped with the starting issue, except mine would start no problem as long as I was on the gas a bit then it would die.
