I am sure this has already been asked (cause I am still a SQUID) but is it safe to run JE Pistons (11.5:1) with Mori Stage 2 Cams without going too stupid with this modification. Also what would be the spark timing adjustment for the JE Piston compression to the original piston?
Thanks

You may want to contact Roger Ditchfield of Revolution Racing in the UK for this type of information (he did development work on racing VTRs for both HRC and Moriwaki). Your main concern may turn out to be getting the crank to last as stock cranks running aggressive cams tend to let go...

You will also need to source valve springs as STG2 cams will not work with the stock springs.

I was going to get the springs from WebCam.

as above it will need the springs to stop it all getting a bit messy..
