I just found a degree key for the yfm350 motor and wanted to know if it gives any gains? I did a search and couldn't find anything.

 

of course it will give you gains, but it also makes your motor run a lil hotter, as long as your still on stock CDI and compression, ide give it a try.

 

Whats it worth? Should i expect a few hp or like .5hp

 

.5 or less prolly. Mostly it makes em a bit snappier and torquier. Really does bout nill for top end.

 

Where did you din it, ill give it a try too.

 

Vito's performance has the degree key, its like 20 bucks. That sucks, im looking to give the top end a boost, low end is sweet now, plenty of grunt, mid range is there, not where i want it to be but its getting there, but the top end lacks what i want. Is the only way to really boost the top end internal mods like a hi comp piston or a cam?

 

id go wit a hotcam, from everything ive heard bout it, it is suppost to be great.

 

stage 2 for top end

 

stage 2 you need different springs right, it recommended?
