Does the fuel injector cleaner helps clean the valves?

Thanks for suggetions.
If you don't have an owners manual, you should get one!

Mine says inspect every 3000 miles or 15 months.
My guess is that if not ridden HARD, one could probably get away with double that.
You are even past DOUBLE the recommended interval so, yes, I think you shoud have them checked. :oops:

FI/Carb cleaner does little or nothing for the valves.
The valve seats are generally self cleaning anyway.
If you have valves "dirty" enough to cause performance problems, then something else is causing them to get that way.
