I just serviced my bike today. I was told in the past that the cam chain tensioners need to be adjusted after about every 4000 miles or so. I was told its a job that requires the bike to be cool, and you have to pull the tank and all that. The Suzuki dealer told me its about a $400 job....its mostly labor ($35 per hour) actually once the heads are pulled. Its not something I would do...I'm mechanically inclined, but this is a little above me.
I brought the bike in this morning and the guy asked me how many miles were on the bike. I told just over 4000. He started in with the "you need to adjust the cam chain tensioner speech".....I just told him I couldn't afford it. He changed his tune, listened to the bike and said I didn't need to do it anyway.....I didn't think so either. I don't hear a ticking sound anyway. My bike runs flawlessly....but then again, except for some holes drilled in the stock muffler baffle, the bike is bone stock.....and though I have fun with it busting through canyon curves, I truly do not beat on it either so that may have something to do with why it didn't need an adjustment either.
My bike has just over 4000 miles on it and its a 2002 SV650S. The guy I had look at it at the dealership told me not to worry about it. I ran the bike for him and he said they didn't need to be adjusted.
