hello,
my problem is still valid
since i 've build my bike i can't really past 6500 /7000 rpms in 6 gear.
In fact the bike go over 6000 rpm on the first gears and more i go up the gear more the area where the bike can't go over is down:
i can't go over: 8000 in 4 gear / 7500 - 5 gear /6500 - 6 gear!!!
I do a lot of testing, but nothing has solved the problem.
It's a 4G5 model with BMC pods and megathon
Carb are very clean, no problem, diaphragm are new
timing is good (tune with flash light)
synchro is good
fuel level is good (clear tube method)
the ignition advance is free and work
I've try 125 (stock)-135-145 main jet but nothing different for this problem
i've try other coil
i've try new spark
The best carb configuration for me (under the wrong rpm) is 135 main jet (10 point more than stock) and needle 3th groove
the bike is very pleasant and powerful under this area
I'm desperate and I do not know where to look
Help!!!
