I have 2003 WR 450F with less than 1,000 miles on it. As you can imagine it is in great shape and for the most part runs great. I have already had the carb cleaned and the bike starts and runs reliably. However, as many of you know, 1st gear hits like a mule and if you happen to be in a tough spot, 1st gear can work against. I know, I know, clutch control is the key and I have been working on 2nd and 3rd gear clutch control when I'm in tight single track and hit helps....BUT I wanted to smooth out the power and make first gear more usable. Here is the plan: (parts are ordered). Going with the Boyseen Quickshot 3 Accelerator Pump, FMF Jet Kit and a 15 tooth counter sprocket. The goal of all this is to smooth out the hit and throttle response. I will report back in one week with the results. Wish me luck.
