I have the HMF and I think it's great. I added the DynoJet kit at the same time so I can't really tell you which mod created "new found" power but I have a much better throttle response. And it sounds really nice.... [img]i/expressions/face-icon-small-happy.gif[/img]

 

guyz i really dont care what anyone saids about a yfz bein faster then a ds650, because their not. we own both now. me and my dad have raced 6 different times switching riders in a drag race. the yfz held right beside it everytime tgrough the first 2 1/2 gears then about half way through third the ds pulls layin about 3 quad legths win to the ds650. but now you put them anywhere where theres curves and the yfz shines. that bike is awsome on the trails!

 

We have two YFZs and a DS650, all with similar intake and exhaust mods, and the DS wins in our house as well. The DS rider has to be pretty aggressive, and pin the throttle on the starting line until the engine bounces off the rev limiter, then dump the clutch in second gear. If the proper techique is used the DS will consistently win.

kingofthemudholes,

I dont get it. You picked a two year old thread about slip-on exhausts to talk about the difference between YFZ and the DS?
