1980 1015cc stock compression and cams. What cam timing should I install them at? I've read where wider is better for boosted applications...

I found the following on KZzone tech tips...

Turbo Engine Timing
Turbo bikes under boost create a tremendous intake charge. In order to release this charge the exhaust must stay open longer than usual. Suzuki and Kawasaki engines benefit greatly when exhaust cams are set at 112 degrees lobe centers. Set ignition timing at 28 degrees.

Sooo, any suggestions for the intake lobe center? 112 degrees as well, so as to avoid blowing all of the intake charge out the exhaust? Somebody out there must have played around with this...

TIA,

Gavin

When I read through this, I assumed it was 112 for exhaust and 110 for intake. This is what I have mine set at. The turbo kit is officially in the mail, so I'll let you know how it works out for me.
