1980 gl 1100 jumping noise during acceleration in higher ge

Postby saluther » Tue Aug 05, 2014 10:19 pm



can anyone please shed some light as to what may be causing a slip in my tranny during harder acceleration in higher gears. It usually happens when I'm in say like 4th gear running low in the rpm range and I try to accelerate somewhat rapidly without down shifting? The sound is very similar to a timing belt slipping teeth on a drive pulley I am also cant seem to get the clutch adjusted to where when I shift from 1st to second gear without it shifting kind of hard this happens during rapid shifts and acceleration.

This "might" be in the rear....You'd have to pull the rear wheel and inspect the drive coupling splines,drive gears,etc...including the driveshaft coupler...

I know this thread is a little old, but this is the first time I've seen it and wondered if you found your problem?

I think it is the cheap gasoline we are paying big bucks for.
My 80 started doing the same thing just as you described.
First thing I am changing is the fuel filter, Then my gas cap as my engine is starving for fuel on fast acceleration.

'slipping' is usually a clutch type issue, if i am at low rpm in fourth, i only accelerate in that situation as mildly as able or possible, otherwise i quickly get or hear complaining type sounds (grunts, groaning, clanging etc) that i never pursue further with more power,

in all other areas, my engine is completely normal i'd include attempting to accelerate outa low rpms in fourth gear, where you have to be very careful if for whatever reason, accelerating outa that deal

dunno what you mean by
cant seem to get the clutch adjusted to where when I shift from 1st to second gear without it shifting kind of hard this happens during rapid shifts and acceleration.


i don't need any clutch adjustments or even perhaps call it fine tuning, for normal shifting results,

an obvious 'clutch slipping' issue is engine reving in excess or not proportional to actual acceleration, which doesn't sound like what may be going on here

'hard shifting' and or 'jumping noise' during acceleration in higher gear could mean lotsa things? accelerating out of a high gear at low rpms situation can and will easily bring on abnormal noises or complaints that would be completely normal from even an otherwise good engine
