Thanks for the laugh, I needed that this morning.

Can I ask you which part of what I posted upset you?

Is it really wrong to check for interference when you change the cam timing? Not much to loose there if you get something wrong, well except for the motor.

Maybe it's the fact that I have never been able to change the timing to get more power out of one end of the power band without loosing some at the other end? Maybe I need to find a different dyno as the ones I have used must be lying to me.

Or was it that I disagree on saying there is a magic number for changing cam timing that will work for all bikes. I really wish it was that easy but you can't even jet two of these bikes the same and expect to get the same results. Throw in the fact that there are 2 different cam profiles on these bikes and that makes it even harder to say one set number will work for everything.

While I agree that changing the cam timing will change the power band. I can't agree that one set number will give you the best results. Sorry if that upsets you.

So it's back to you. Either you can throw personal insults some more or you can show me the errors that I have made to further my education in this matter. I've been building bikes for close to 35 years and learn something just about every time I get into one, so far from thinking I know it all, I'm just someone who tries to pass along the things I have learned. I am also always open to learn new things, if they can be proven and justified.

 

im gonna go another tooth up in the rear for my track setup, 44 tooth, mainly because my slick is a 190 and well im just greedy and want more for track days, plus if i go to a bigger track i can leave my 43 tooth on. 15/43 is great, revs higher gears come faster but the bike is so much fun to ride

 

Well my feelings on this are rather clear. Unless you find yourself on a track where 1st gear is too tall to exit the corners dropping the gearing is rather ridiculous.

Maybe it's just a west coast thing but no track around here has a corner tight enough that you can't keep the bike above 5k in 1st.

Then again I tend to use all 6 gears in the transmission.

 

well the track we have closest to us has some tight corners. personally i dont like using first gear on the bike as i dont have the control thats needed for first gear through a corner and the bike will stand me up at part throttle in first gear if im not easy on it, plus i still have a little fine tuning to do to the carbs and last thing i want is the bike to hesitate a little whiel i roll on first and then come to life mid corner. for the most part it doesnt do it but with our temperature changes it changes the way the bike behalves. so id rather use second over first if possible. i come out of some of the corners mid to top of second, some in third, i could use first in a few but it makes no sense as id have to shift to second mid corner so id rather come into it in third gear and hold third than shift to second and require an upshift. same goes for one corner that i come into in third gear and its a double corner, second is much tighter but you maintain a lean while transitioning the corner and i have to take second geareither jsut before i hit that corner while leaned over still or come out of the second corner in third with the motor at about 4000 rpm. that double i could do in third if the bike were geared a little higher. thats why im after a 44 tooth sprocket, ive got a 43 tooth so if i go to a track thats a little bigger i can use the 43 tooth and on one thats tighter like the one were running the 44 would do just fine

 

So by reading your reasoning it sounds like you are geared too low already..... so why not gear down even more......
