Gears not engadging

Hi Guys
Ran this weekend the desert drag wars and had lots and lots of problems with my gearing. Struggled to shift from 1st to 2nd. Then approaching the line in 4th it felt like the bike is cutting the ignition
Any suggestions?

Sounds like you've got tranny issues. But I'm not sure as your description is a bit vague. What is wrong with the 1-2 shift? Hard to get into gear or popping out of gear.

The other issue sounds like the gears aren't fully mating and the gear dogs are popping in and out of the slots.

If I was to speculate, you've got shift fork and/or drum damage. Both require opening the motor go replacement.

I had the problem before and found two out of the three shift forks bent and to top it off my second gear's dogs were completely worn out. I replaced all new. Now, i am running both dynojets quickshifter as well as the mps air shifter. What is the possibilty that my air shifter is causing this to keep happening? Could it also maybe be that the nitros is coming in too hard?

Very likely that is the issue if the air shifter is too hard too soon and not waiting for the fuel to get interrupted fully. This is part of the reason I'm not a fan of the Dynojet quick shifter. It cuts fuel at the injectors, which takes a small amount of time (milliseconds) for the interruption to travel down the intake runners and for the engine to respond. I feel that the ignition interrupt is more immediate.

With the kill times set to milliseconds for the shift to occur, the tranny might not be fully unloaded before the air shifter attempts to change gears.

Do you suggest I set the kill time for a longer period and try again? What is strange to me is that I never had the problem before I changed from slick to semi slick. Another thing, what do you guys think about this pair valve being blocked off?

get a shifter set up that lets you adjust delays, that way your ram isn't trying to shift before the engine unloads the trans, otherwise it will continue to break parts. Here is an example of what I am using, it kills the engine and then after a set delay shifts.
