ZXR400 Cam Info.

ZXR400 Cam Info.

ZXR400 Cam Info.

(OP)
Hi all, hope someone can help here. Have scoured the net for this info but to no avail :(

I'm look for cam lifts, durations & opening times for a ZXR400-H. An older thread by MBurgess yielded the lifts & durations (thanks!) but just wondering if anyone (Mburgess ;) ) knows when they open?

Cheers,

D.

RE: ZXR400 Cam Info.

Here is a manual.

Thanks guys - actually found it at the start of the manual... what an idiot I am! ;)

MB, just prepping a racebike for next year but intend sticking with standard cams for the time being.

RE: ZXR400 Cam Info.

Make up some slotted adjusters out of the std cam wheels. A little bit can be found in the timing. Only prob is the std wheels have to be annealed, machined then re hardend.

RE: ZXR400 Cam Info.

Just grind the slots and forget about heat treating them.

RE: ZXR400 Cam Info.

Unfortunatly std cam bosses are solid (cam sprocket & boss a single forging). You will need to anneal them to machine them down to cam sprockets, slot & machine up some bosses, then re harden. Not sure if ZX6 use same width hivo chain, might be worth checking.

MB
