I bought the pro circuit ti-4r and put it on the day before christmas, got carbureator jetted and i rode on a track once and i had to rebuild my top end, i have a 2009 kx250f, i believe that my motor was dialed in without a pipe and so thats what may have caused it because the sudden change , but the pipe sounds good but for the money its not nearly worth $1,000 after tax. Ill be the 1st to say save ya money for something else
as always procircuit has good quality, but for the price i didnt notice a big power gain. It felt like it just moved the power around on my 2009 kx450. It maybe lost a little off the bottom about the same in the middle but had good top end pull. Definatly looks better than the kx stock exaust. It was better but not a lot. When u spend that much money i would expect a little better. Dont know if their are any better ones out there but i might try a differnt one next year.
I bought this exhaust for my 09 CRF250R. It took away a tad bit of the hard hitting bottom end and added some upper mid and top end. Overall it kind of moved the powerband around a bit and added a little horsepower to the upper mid and top end. The 09 CRF250 is already a really strong powerfull bike (it won the MXA 09 250 shootout) and this exhaust adds a little more power.
WOW it added tons of power , sounds very deep almost like a growl
Great Throttle Response, Looks & Sounds Great, Improved Power Across Entire Range, Easy Installation (Takes 15 Min If You Follow The Instuctions), Just Follow Jetting Specs For Your Bike From Pro Circuit Website And Your Set, And Even Better It comes With Extra Packing/Bolts For The Silencer/And On The 09 Yamaha I Comes With A Shorter Bolt For The Silencer Mount (This Kit DOES NOT Use Factory Rubber Mount In Silencer).
2). Kawasaki makes a tool for the fuel injection adjustment program it runs right around $ 559.00 dollars and you need a battery to operate the system or via a lap top...your dealer should have the tool but some dealers don't carry the system because of the price
3). your bike will not run right best bet is to buy the tool its actually quite easy to use and really works well for programming the exhaust mods, fuel mods and filter mods as well
