shift under load

[fullthrottle]

hi guys just wondering if anyone else has the same problem.

when i am in a race situation that requires me to shift up without letting off the throttle but using the clutch it wont shift unless i back the throttle off abit, the bike has always been like this since new i have tried motul and maxima g/box oils. On my 125 i could just hold the throttle pined and use the clutch and shift. i feel like i am losing quite abit of time over a 6 hour event just because of this. I dont ride like this everywere but sometimes its required if ya are hearing me
any ideas???

keep trying different g/box oils?? or are they all like this??

any ideas?

The 125 probably has under-cut transmission gears. This allows better "meshing" of the gears under a load.
There are shops that can perform that mod for you.

Trying different fluids may be your best and cheapest option.

Here's a description of under cutting.
