Anyone have a bunch of hours on a 200rr? A friend of mine has one. He's got over 50 hours on it and loves it. I've ridden it and another one. Great bikes, so nimble with enough power to hang with the 250/300's except in sand or maybe long hill climbs.
Anyway, to my question. My friend's 200rr started losing low end intermittently sometimes. At first we thought it was an exhaust leak so he removed, inspected and re-installed the pipe with sealant at all the joints. That didn't fix it.
Messed with the carb a little and that didn't fix it.
That's when I rode it. I put about 2 hours on it and it felt to me like the power valve sticks. I rode it up a hillclimb pinned wide open. Once at the top the terrain leveled off and turns into a whooped out turn track section. That's when I noticed the bike had no bottom end. We decided it must be the power valve sticking when it reaches full open.
He called our local dealer who suggested maybe it was out of adjustment. So he adjusted the power valve at the pivot arm behind the side cover. This seemed to work for awhile but it also changed the power aspect of the bike. Not in a good way either, it seems there's no adjusting it to get the power delivery it had when new without the valve sticking when the throttle is pinned.
To be clear:
1. we adjust the power valve so it doesn't stick and it doesn't have as much power on top
2. we adjust it so it has power on top but then it sticks
3. there is no sweet spot, it either sticks or doesn't have top end power
We have not removed and inspected the power valve yet but that is next on the list.
Does anyone have any other advice?
Is there an after market pipe that changes the power aspect to compensate adjusting the power valve so it wont open all the way?
