I rejetted the carbs and removed the airbox snorkel on Sunday because it was raining and had I nothing better to do. I already had the Yoshimura TRC carbon fiber full system installed. I used a DynoJet stage 2 Jet kit (#2193) and used the #98 jets with the neddles on the middle setting. Doing the carb adjustments were cake, removing the carbs from the bike was another story all together. The airbox utterly and completely makes removing the carbs from the bike a complete pain in the ass. There is not much room to maneuver around the airbox inside the frame. No, I am not interested in removing the airbox and trying to install pod filters. Although it would simplify doing any future carb adjustments.
I finally got to ride the 250 today because it rained all Sunday and Monday, I was dying to ride it and see what changes the jetting made to my 249cc screamer
The bike pulls off of the line with much more ease now, I don't have to give it a whole lot of gas, and the engine doesn't bog down as bad if you let the clutch out too quick. I felt that the midrange response and pull has gotten much better, especially in the 7k range, the motor just feels like it is breathing easier and more eager to rev now. The top end performance is also improved, it pulls very eagerly to redline in a hurry. With the breathing mods and the rejet I am very pleased with the results. The bike sounds great, looks great, and performs excellently (for a 250), no regrets here
Next mods will be the rear seat cowl (which should be here this week) and Puig smoke windscreen which I have already placed an order from bulletbikes. Man, riding my 250 and doing mods to it has become an addiction far worse than any drug could cause, haha.
Rejet / Airbox snorkel removal / Yoshimura full exhaust
As far as the jetting goes I went with the DynoJet recommended settings for the kit. For a snorkel removal and exhaust system they recommend #98 jet, needle on the middle setting, and 2.5 turns out on the mixture screws. It seems to be right on the money
