Got a 770 street avenger on it now that I had laying around......
Oh, I put the next step stiffer springs in the eddy, along with squirters from a 750 eddy, and yesterday I threw it on my 360 and there was no hesitation on the 360. Every engine has it's own requirements, and this is why I always advise to give the engine what IT wants. This includes timing, carbs, etc. etc. Rule of thumb will get ya ball park, but that is the beginning of tweaking.....
