Just curious if anyone has had any reliability issues with this mod?
How many miles/hours have you guys done with/without problems?

ZERO reported failures and most have been running this mod since early 2003! It has proven to be a very safe mod....DO IT!! :)

I did the cam swap in my 02 YZ426 a few months ago and love it! I have not read of one failure. I wish I would have found this forum and completed this mod a couple of years ago. Don't wait, do it and enjoy it! :)

Why don't you just get a hot cam, upgradeing to stock parts is dumb IMHO.

because of $$$ (everything down here in OZ is much dearer), also, I want a grunter not a revver so I'll be better off with the stock cam.

actually I liked the powerband of the stock cam better than the hotcam...with the hotcam it was a chugger and then hit in the midrange...with the OEM 450 cam it pulls smooth from idle to the rev limiter....much easier to ride and just as fast. Oh yeah....the OE is cheaper too :)

Sorry I still cannot rap my mind around upgradeing to a stock part.

Whatever floats your boat though.

? Since when was stock and o.e.m not the same? You must have meant aftermarket.

It is a STOCK part for a YZ450F....different cam that was designed for the "oh mommy it rips my arms off 03 YZ450F"...might as well be aftermarket.

The decomp cam in a 426 isn't OEM, it's a newer part. Spending the extra money on the Hot Cam is silly in my opinion, when you can get a stock cam way cheaper and get basically the same results.

1 year (50 hours) on my 450 cam with zero problems. Hands down the best mod I've done to my 426.

That will be news to all of the guys who put Z06 cams in their Chevy half tons.

This is a great mod! I did mine 18 months ago. Starting is awesome. What is great is not worrying about stalling the bike over big jumps. (Not a good time) It is great if you stall you can use the momentum of the bike to start the bike again. :)
