I've measured port timing and it's 170/120, I thought of 185/125 with, an exhaust port 70% of the bore diameter. Still have to run some calculations about that. What do you think?
Exhaust is without the catalyst.
Have you tried those BGM needles with a 28mm OKO, I know I would probably need a very thick needle, which one do you use? They have some strange needle codes, not same as keihin, so keihin needle chart is useless.
Thanks for the nice comments guys  |
185 degree exhaust duration is good for a street usage! I've used a custom made needle for the configuration! I made it on a lathe, and than I fine tune it! But you can find needles for a Keihin PWK carb..
