That part isnt making sense to me....if you ran 11/69 with the stocker 208cc, you should be needing more gear not less gear, for the big bore stroker, since the big bore stroker is going to make more power and at a higher rpm, with a higher peak torque than the stock engine did. What rpm do you have the clutch engaging at and what is your target rpm on the track, how big is the track, and what air pressure are you using?
A big bore Honda stroker should be making peak torque around 4400-5000rpm, maybe more or less depending on the cam and rest of the build, i would not have the clutch engaging anywhere less than 4500 if it is a true open honda big bore stroker. I had one of these engines last year that was 3" bore .175 stroker with a .356 cam and it was making peak torque around 5000rpm, turning 9500rpm on the small tracks.
I guess im not understanding your explanation but it maybe im explaining it wrong.
So if you go out and your turning 9500 at the end of the straightaway and you want to drop top rpm to 9000 why wouldnt you take gear off (meaning higher gear)?
