Spark plugs and Tires.

No question. No advise. Just changed plugs. 35,000 miles. NGK. They looked like they could go 3 times that. Gap has not even changed. It has 6 new ones of the same anyway. Dunlop E3 7,500 miles. Looks like it could go 3 times that. I like the  Dunnies for mileage. But. Even when balanced  they still "gallop".Just my observations. No warranty expressed or implied. Ride safe.

I removed my number 6 plug once to avoid hydro lock from a leaking petcock. Other than that, same plugs are in the bike from new back in 98.

I wonder if something like Ride-On would help the "gallop"?

What tire pressures are you using? Too low and tires get cupped. Try 40PSI in the F/R .

Are tires out of round? Dyna Beads work great for a continual dynamic balance. As said above, keep the tire pressures up, 42F 44R.
