J gap

[addicted]

anyone J gap their plugs? seems the GPR's can do it once they change there coils. Can the "old school" ignitions fire them on the stock coils?

[w/rpm500]

yes.. most claim some gains, 50 rpm's I think is about the most I've read..

Do you need to change your coils on the gpr's?

Side gapping / J-gapping will work fine on all of them. No need to change out coils

Mine idles smoother after I did this, that was the first thing I noticed on my TACH

What kind of gap would you guys suggest for our older ski's? Is indexing still a good idea with J gaps?

I set my gap at the recommended gap setting, then I made the side cut.

This is a new idea for me to try. I'm in the mix of doing a lot of things to my craft right now. How would you go about indexing the spark plugs? That has to do with the gap of the sparking electrode right. Like the last person said, what kind of a gap are we talking about for the GPR's??

GPR plug gap should be around .090 for maximum performance.

I also forgot to add, if you change the plug wires to solid core instead of suppression core it is even better.
