lesser forces on transmission with cam swap

Hello,

i know the cam swap thread and have already read all of the messages, but since my YZ426 01 broke down i have a question which is not discussed in this threat until now. Background: In the summer i tried a new huge table and have problems with a stable airtime. During my tries to bring my front wheel in a better landing position my engine went two times out and the following landing was all the time a struggle between surviving and crashing. The result of the second landing without running engine was a broken 3 gear. :cry:

I can imagine that the forces in the engine are huge if the motor will be started from the back wheel. Could a cam from a YZ450, because of the automatic decompressing system, reduce the forces at the TDC? A 450 cam is much cheaper than a new transmission.

Please don´t look at all the mistakes i wrote, but i´m a European student in NYC and still studying the language.

Regards Martin

Congratulations for the nice forum, the speed of changing informations is really impressive. :cry:

I belive that was one of the fixes of the 450 cam.

Your english is better than most Americans (writing, anyway)! If you didn't tell us you are new to the language, we wouldn't have known !!!

ABSOLUTELY!!! The cam makes the bike easy to bump start....which is what your doing if you kill it in mid air and hit the ground with a dead motor. I highly recommend the mod for many reasons and this is just another one of them.
