FMF JET KIT

Put this on an XR650l and it worked great first try. Major increase in performance. Well worth the 55.00 dollars.

Kit fits as advertised.

I had a professional mechanic rebuild my carbs and all the parts fit and the kit was complete. Bike runs like new (a 1980 Suzuki GS 750 EX)

boyesen pro series reed Rm 250 - 2003

The pro series works great. It took away a little bottom end power but I adjusted my power valve and dang this thing boogies. Great product.

Torque!

Improved hole shots, cornering and midrange. Didn't lose any top end but not sure we gained any either. Tons of low and midrange improvements. Installed in 30 minutes. Well worth it!
