I can see your problem Paul. Not a lot of room under the
top of the cowl.

How far would you need to move the pulley out to clear
the ign pickup? I think a 1/4 inch would not hurt anything.

Paul,

I am not home right now, but when I was looking at it I was thinking
somewhere around 3/8".  I am going to have to figure out a side mount
for the renesis.  I appreciate all the responses.  I need to think also
about belt slip above 4000 rpm it sounds like.... plus a different size
belt.

3/8th would probably be OK but it looks
like you will need a lathe to make a spacer that pilots
on the crank shaft and water pump shaft. This to be absolutely
sure the pulleys don't have any run out and are concentric.

Mount the alt as high as possible to keep as much belt
wrap on the e-shaft pulley as possible.
