Hello all. So this is my first k bike, a 92 K75rt with 105k miles. The original owner had the bike up to 103k and the PO maybe rode 1.5k in 2 years. I have a stack of paperwork and a book full of service stamps.
I have only ridden it 100 miles so far, so I may be premature in my questions. The bike runs great. Idles around 1250, had the throttle bodies snyced 9k ago, fuel filter replaced, air filter, and some other stuff. The PO had non ethanol in it when I bought it and I have put non ethanol in it too. I should add that the 9k was 9 years ago.
The air filter looks clean, the tank looks clean, I checked the tb sync with my twinmax and they are spot on.
Ok, so above 5k the bikes feels throaty, not smooth and linear like it does up to 5k. Is this a k thing, or should it feel smooth all the way up.
What would cause the bike to not feel smooth above 5k? Fuel or air?
