Spark plug gap

bronevaya · 05-01-2008, 04:09 PM

my manual doesnt say. I put a champion in gapped at .060 and it doesnt run well (actually its probably my carb too)

any recommendations on gap?

I gapped mine at .028 it was the recomended gap for an old honda 200cc . seemed to be fine.

Probably too much gap for the stock coil. Go to what AZ used and try that out.

My stock Plug was gapped at 30. When I replaced it I went with the same...Bike runs fine.

owners manual from Roketa shows the needed sparkplug gap to be 0.6mm - 0.7mm - this works out to 0.027in which is what i gapped my new plug

.060 is waaaaaay too much. The stock coil cannot jump the gap. Stock is around .020-.025 on the GY's, Porterz runs .035 and seems to get better engine response and more pep going along the argument of larger spark = more complete combustion of fuel, in fact he has a thread somewhere on here about it. I would run the stock gap or try his.
