My buddy with the Le YFZ came up and we did the cam mod to his yfz today. It runs awesome. It actually impressed me how good it was running. We'll have some times on it this weekend as he was running 5.5's this past weekend with the pro wedge's, wheelie bar, lowering kit, and alba pipe set up.

But he is running a 170 jet with the alba needle...he was a smidge lean before, should I go ahead and jet him up to a 172 or 175 since the cam mod? I know we are going to have to adjust the idle some as it only idles 1/2 the time.

But should the jet's be bumped up?

Also we got the miss out of it from before, and it's running top notch now. It even looks like a drag racer with the wheelie bar, and the fact that it sits about 3-4" off the ground. [img]i/expressions/face-icon-small-wink.gif[/img]

 

how does it compare to your bike speed wise?

 

You can tell the differnce in hp and torque between the two. The Raptor has a ton more, but the YFZ rev's faster(like you didn't already know that). The fastest 300ft time the YFZ ran was a 5.5 which is .2 faster then what I ran with just a pipe on my Raptor.

We haven't raced on pavement or anything, but the margin is a couple lenghts in 300ft.
