2009 Kawasaki KLX 250S, I purchased the KLX when looking for an on road off road bike that was not too high, the first owner had installed a lowering link whick lowered the seat height by several inches, he had also inslalled an FMF exhaust system and K&N Air cleaner for improved power, after riding it a few more time I too wanted more power and foung that B&B Cycle Restoration in Kansas offers a complete 351 big bore kit, asfter online research and a phone call to Bill Blue the owner, I placed an order for the kit along with an upgraded carburetor that had a built in accelerator pump for quicker throttle response. At the same time I installed a new memory foam seat from Seat Concepts and a larger fuel tank to extend the bikes range. I have put less than 1,000 mikes on the bike after the big bore kit, new tires chain and sprocket. The best way to contact me is by text, if you call, please leave a message, I will call you back.
