Transmission problems when bored?

[Honda2000]

I have searched and i haven't found anything. I am wanting to bore out my 400ex to a 426. I was wondering if i would have to do anything to my clutch or transmission. I was wondering if anyone had any problems with the transmission going out. THanks

Clutch will need to be upgraded, transmission will be fine

well the 400ex clutch would need to be up graded eventualy. the stock clutch cant handle much more than stock power. its one of the 400ex's week spots. the tranny should be fine. you will runn hotter and need a rebuild sooner probly.
