happy with mine

Installed on a 96 Road King with mild cam. She does 2nd gear wheelies now and also calmed most of the popping on deceleration. I would recommend this product!

Vance& Hines Fuel Pack

Throttle response is like night and day from stock. I really enjoyed the performance it gave my bike. Excellent products would definitely recommend to a friend. Installation was extremely easy in my 2006 Softail Heritage.

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)
