5 posts in this topic

Hi would 2000 yz426f valve kit fit straight into 2002 model. I've just blew my piston and cylinder to pieces and have started a slow full rebuild but have been offered a full valve kit for less then £150. Bargain??! I'm looking to find a cylinder also but am struggling any help appreciated.1410903936630.jpg1410904486120.jpg

The '00 valves will fit, but they will require the use of the '00 springs because they are stainless steel, and 40% heavier than the Ti valves your head was built with.

Thanks greyracer the kit I've been offered is everything inc all seals and buckets springs etc. Can you tell from the pics if that cylinder is just worth junk or is that repairable? I'm not mechanically minded but am willing to rebuild this MACHINE from the heaps of cases parts its now in maybe (most likely) with a little or a lot of help from TT thanks in advance. Phil.
