02 954: Bogs if you wack the throttly + Strange vibration
I have an 02 954 and it's recently developed some strange problems...
1) If the bike it sitting in neutral and you twist the throttle moderately, the bike seems to bog a bit before the RPM's come up.... Is this normal?
2) the bike has seemed to develop a strange vibration/noise at abour 4K rpms up.
It's hard to describe but it a very small vibration at high frequency, it's not enough to effect bike handling, but it does make my hands numb after a long ride (never did before)
The bike has 10K and as far as I know, has original plugs. I change the oil at 2500 miles. There is about 2200 miles on the oil now. It's honda HP-4. The air filter seems ok too. I hear people say something about adjusting the air box flapper and some device in the exhaust?? I don't really know where to go with this, time to change plugs?... any thought would be helpful
ALSO when you turn the key to prime the fuel pump, the (humming) sound the pump makes sometimes seems like it's not that powerful... IE the wine from the fuel pump changes it's frequency... can these pumps start to go out but not die completely?
Bike is stock except eron slip on
