it would be a great improvement from stock hotter spark crisper throttle response and quicker revving
Yfm350 serious power build!!

Yeah I've read a couple of posts about the cdi but you would only get max performance outta them if you've got some engine work done right?? I love my 350 but it just seems if i throw money at my rappy Ide still be behind all of my mates 450's, 660, and 700's....

A 350 will only hang with 450s bearly if the 350 is modified completely
Even the 446 wont beat a 450

I don't know I bought my 05 rappy for 3 g's after a full fmf exhaust clamp on airfilter re-jet I'm down all most $400+ 
I know the machine won't be faster than anything other then another warrior/Raptor but it's soo much fun passing ppl in top gear while there on the sidelines cos there quad has brOken down lol But all in all so the monster coil would be choice right?? =)

Honestly fst is pushing it
No its just almost to the point of having too much added throw

The biggest issue with the stroking Ive heard is no one does anything with the counterbalance, so the vibration eventually takes its toll. Atleast I think I siad that all right!! LOL
For a quad that doesnt get raced and is just a trail quad Id say no bigger than the 379 kit

Yeah, I also believe that a lil added stroke wouldn't hinder the Warrior from being rev happy but would still offer a lil extra on the bottom/mid. The 379 is where I'd go I think & opt for a custom 85mm piston for it in the future. I wish somebody would just market that piston, hell ya gotta buy it seperate anyway.
How would something like 72.5mm x 90mm do? I'm sure I'd have to trench the cases for the +8mm crank. I'd want comething that could take a 15hp shot of nitrous. I can garentee a 350, made to 461, and HC2, Drag Pipe, 220lbs, and add a 15 shot to it, would be the fastest 350 here, but for how long?

a 90mm piston? Don't think anyone has done that... I think like 89mm has been the biggest I've seen.

If I find anything going bad in the lower end of my motor when I tear the top end down this winter, I plan on going with the 379 kit. As off right now I dont know if my extra jug is useable, so my plan might change.
na i dont see that as a problem, a properly made crank wount need much counter balancing
