I know it's to late but I would have went for the HMF, I have one on my 250ex and it made a huge improvement, kinda loud though. Just my opinion.

 

yoshimura is da best more power better sound

 

I was wondering, I im thinking about getting a Yoshi slip on ( instead of a big gun/pro circuit) for my 2006 ltz-250 and a Moose jet kit, will I notice a change and is it worth It ?
Im new to this whole thing and would like if any one could help me decide if it is a mess up or a good to go?


Ltz-250 .2006
UNI filter.
Maxxis razzer 2 on back.
Fly bars.

 

I had gotten a yoshi slip on for my 2006 ltz250 and seems like the clamp dont clamp right on the stock head pipe, im getting popping on decel ,like going down hills or after a steady pace on throttle then pop, is their a adapter or some thing i need to do for it.
