February 8, 200818 yr So the Scorpa manual recommends Champion spark plugs, with a gap of 0.7 to 0.85. However my 07 scorpa is running an NGK. What is recomended or the norm?
February 8, 200818 yr One of the first 'mods' I did with my 07 SY250 was ditch the Champion plug and replace with an NGK BKR5EVX as reocmended by Nigel Birkett. Its been in 12 months and is still as clean as a whistle and I ride nearly every weekend.
