March 14, 200620 yr 250 is a champion N7YCC think its probably the same. Some recommend a N5YCC think it burns slightly hotter.
March 14, 200620 yr Author I have just bought this bike and it has an NGK BP6HS fitted and that plug is a lot shorter reach than the Champion N7YCC. Is the wrong plug fitted or would there be good cause to fit the BP6HS ? Could it be to lower the compression and smooth the power delivery? Edited March 14, 200620 yr by Dab Myster
March 15, 200620 yr I can't imagine that the (7mm/0.25") shorter plug would help. The correct NGK plug would be one of the following: BP5ES, BP6ES, BP7ES. I've successfully used all three heat ranges, but I typically run the middle heat range, i.e. the BP6ES. Hope this helps, Don
March 15, 200620 yr the reccomended plug is the BP5ES and i often run a platinum plug heat 6 just for durability. I think that is something like BPR6EVX BUT IM NOT SURE ON THAT ONE. Bob
