686 Raptor VS YFZ450
I am only pulling a length or two against my buddy's stock 450 when draging thru about 4th gear. I only had 20 min on the engine at the time....maybe it needs to break in a bit.
I was hoping to pull at least 5 quad lengths. I think I need to do some tweaking on the jets or something.
