dab myster Posted March 14, 2006 Report Share Posted March 14, 2006 What spark plug should be in a 2004 Rev3 200 ? Quote Link to comment Share on other sites More sharing options...
wilsoff Posted March 14, 2006 Report Share Posted March 14, 2006 250 is a champion N7YCC think its probably the same. Some recommend a N5YCC think it burns slightly hotter. Quote Link to comment Share on other sites More sharing options...
dab myster Posted March 14, 2006 Author Report Share Posted March 14, 2006 (edited) 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?

dhubbard Posted March 15, 2006 Report Share Posted March 15, 2006 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 Quote Link to comment Share on other sites More sharing options...
bob Posted March 15, 2006 Report Share Posted March 15, 2006 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 Quote Link to comment Share on other sites More sharing options...
