A question about spark plugs

Recommended Posts

Hey guys, I just got bike back from the shop today. I had to bring it in because my clutch rod and ball seized up after upgrading to stiffer springs and stuff so they upgraded me to the pancake bearing adjuster. But i also had my guy rejet my bottom end cause it was running like crap on bottom end. Well whenever I looked at the bike at the shop before i picked it up I noticed that he dropped the spark plug heat from the stock NGK 8 to a NGK 9. Just wondering why you think he might have done this...Im planning on asking him myself but he wasnt at the shop today.

So im guessing its not unheard of to run colder plugs in banshees? It runs great, but i find it is a little harder to start it, which id point towards the colder plug for doing that.

i personally run the 8 ngk resister plug . i have run the 7 and it kept it from starting ruff and run alot better in the cold. if your just trail riding go wwwwwwith a warmer plug. if you really run the bike hard for longer periods, run the colder plugs like the 9.

There may be a perfectly good reason to run a 9 on gas...some people setup and jet their motor that way.

 

Man i hope your right, I havent been able to get a hold to my guy to ask him. Thats pretty much all i been thinkin bout since I got my bike back from the shop.
