I want to detune a yz450f street-legal supermoto. It is mostly A-B riding, I'd say 30% highway miles, with some twisty roads once in a while. Very tame riding.
The maintenance schedule is really strict on this race bike. Given the tame riding, does that automatically reduce the maintenance schedule, and by how much?
I don't need anymore than 35hp or 40hp max - it's already a very light bike. Is it possible to get a low compression piston (ie. 10:1 or 9:1) to reduce it by this much? Or what are some options I have for detuning?
Stock it is recommended to have oil change every 5 hours, valve check/adjustment every 20, and piston/rings every 40.
I have a goal of increasing this by 7x between riding style and engine detuning (it'll give me roughly oil change every 1000 miles, valves 4000 miles, piston/rings 8000 miles).
I like having a commuter that weighs just 240 pounds, so going the easy way and buying a street bike is just not what I'm going to do.
Does anyone have any insight as to how I could achieve my maintenance schedule goal?
