My 2000SE has developed an odd "Stumbling", when cruising 65mph, causing the engine to throttle back very slightly.

It only occurs when:
-A Headwind is encountered, or
-Going Down hill.

I don't think it's a Fuel Supply Issue (eg Bad fuel pump) as I can:
-Negate the effect by immediately giving More Throttle, to compensate.
-Avoiding the problem by cruising at a higher speed (>70 mph), or lower speed (<60mph)

It never occurs when going Uphill... This might suggest Driveline Slack, as the line would definately be under load (and not alternating between load & non-load) in this situation.


Any ideas?

If you suspect the problem is in the drive line Alex, the first and probably easiest thing to examine is the universal joint.

When my final drive splines were wearing out I would get that kind of a feling once in a while...

It got so bad that eventually it woud kcik out the cruise control when I hit a bump...

Found a ZERO mile trike take off final drive and a 9000 mile star gear to mate with it and now it is all wonderful again...



It would be worth a look....?

Both Universal Joint and Splines are OK, and checked just 4k miles ago.

"OK" meaning no obvious visual wear.

I kinda knew that would be your answer....:?

You are typically on top of the maintenance on your bike(s).

Update: The Stumbling/Vibration problem has Gone Away!... and I don't know why. Put 300 miles on it this week, and not a trace of the former issue.

I had the bike parked for past 3wks, and did routine tune-up on it... Somehow I fixed the problem, and am wondering what the cause was. If it was Tune-up or Fuel-supply related, then it may be the case that a Rough Running Engine can cause Vibration that otherwise can be mis-diagnosed as a bad driveline (eg U-joint)

Work done:
-New spark plugs
-New fuel filter
-New sub-carb air filter
-Cleaned and oiled K&N air filter (It was very dirty)
-Removed the Fuel Petcock (permanently)
-Oil and filter change
-Removed and re-installed compufire alternator (no change to rubber dampeners, or position of them)
-Applied a shot of teflon lubricant to both slides in the carb, in case they were sticking

Curious....



It must've been ONE of those things...

The alternator seating perhaps..?

Or a gentle "miss" from the plugs, tune up items, etc...?

Bad gas in the old fuel filter..?



Aside: I will be interested in the overall performance of the bike over time WITHOUT to vacuum petcock....



Just wondering if it creates any unexpected issues....:waiting:
