So i've gotten my bike tuned and it feels smooth through the whole range of throttle. The problem with overheating was due to a pretty serious air leak at my reed block. i got that fixed, downjetted and now my temps are staying between 270-300. It will occasionally hit 350ish after a long run at WOT or uphill.
So not necessarily a problem but i'd like to see if anyone has any suggestions on what I could do to make my setup hit 9k. I'm currently topping out at about 8700 rpms, which puts me at ~48 mph for top speed. I've heard that this technigas next pipe revs to about 8500. So i'm wondering if that's what's stopping it where it is.
If that's the case then is there a way to use the timing to squeeze out another 300 rpms. According to the wiki, when you retard ignition timing you raise the temperature of the gasses as they exit the exhaust port. This makes them move faster and in turn raises where the powerband is.
So if I'm understanding this right, if I was to retard my timing a bit more then that would raise the rpm where my pipe hits.
So I guess my question is can I hit 9k with this pipe and setup by retarding my timing a little bit more, or am I stuck hitting a wall at 8700 rpms until I get a higher rpm pipe?
