Hi guys,
Strange symptom.
Upon take off at between 0-15 mph I get a lot of vibration on the front end.
So much that it caused the straighter valve in the air valve stem to become lose and leak air.
Potential causes? What part of the transmission might be affected if it is in fact a transmission issue?
Thanks.
-
Straighter valve or Schrader valve? You mean the little spring valve thingy that screws into the tire valve stem?

Yes, the valve inside the air valve stem where you pump air into the tire.
But that was just a side detail, the main inquiry is regarding transmission. I have an appointment for a diagnostic next weekend but want to go in there armed with knowledge.
Any idea what are some common causes of low end throttle vibration?

My thinking....
Big-time clutch chatter?.....after 15mph clutch locked up and chatter gone?
Front end vibration - and you say it is caused by something in the rear, "the transmission"? Clutch pads glazed might be the easiest and least expensive to fix....unless belt is failing.

Mine was pretty bad, possible.

The drive Belt was prematurely replaced at 10,000 miles, and there was only minor glazing on the original belt. That was about 1500 miles ago. I highly doubt it's the belt.

Well, would you care to share the solution you came to?

Thanks MJR.
Would you be willing to help me determine if this is the case?
I could drive out there next Friday if you're cool with it.
I just don't know how to take stuff apart and all that.

Would it be inconvenient to you if I got there around 5:30 or 6:00?
If so just let me know, don't want t bug you. I also wanted to see if you felt anything wrong with my bikes performance.

By the way MJR,
Next time could we please try my bike on the freeway to explore the other symptom I mentioned and perhaps get your opinion on that?
Thanks.
