Any one running these?
Did that also, 13/42 stock is 14/40. I am not a full time racer, but I do attend track days as often as work will allow. If your willing to spend money on your 250 I guarentee the smiles for miles will always be there.Probably be better off with a new rear chain sprocket and keep engine stock, unless you are racing.
I didnt like the look of the Takegawa tuner it just doesnt look like a tuner to me, maybe I have to many PowerCommander modules. I would stick with the PCV if you already have one.My question - thoughts on whether to use the Takegawa tuner or my current PCV with a new custom dyno tune?
600 is running very well. (The rider can still use some improvement, though.) Had the engine built in the off season by Steve Upchurch at Race Engine Services (RES), and it's hard to keep the front wheel down exiting the turns and at the start. More power, way more smooth torque...^ Good post. How is the 600 holding up?
I have the Takewega 305 kit on my shelf, the cams were fitted a while back with a straight through exhaust for a 300. What figures are you getting with the power commander.Ok so had Repsol CBR250R with all the fixins Takegawa 305cc big bore, Takegawa cams, K&N air filter, Delkevic full exhaust(header back), power commander with real deal dyno tune running 100 octane leaded race gas. Everything worked like a charm but make sure you get a good connecting rod or it will spit piston out side of motor. Other then that the cams really wake up the bike good investment.
