Shuder on take off

Post by Prlwng »



New to me 83 1100a.

Noticed it a couple times turning corners in 2nd gear. Upon acceleration would get a shuder. Almost like a preignition. Or clutch slipping. Notice it now also on take off in 1st from stop on hills.

Any ideas? Vacum leak, timing not adjusting, clutch ready to fail?


Do miss reverse of newer wings.

A couple quick suggestions.
Get your RPMs up a bit and see if it helps. Lugging can cause shudder. Bring the revs up a bit when leaving and when downshifting and accelerating after slowing down.
If the bike has been run on synthetic oil it may have affected the clutch. When I first got mine the PO said that he was running on synthetic but did not mention whether it was automotive or motorcycle specific. I switched over to Valvoline 10w-40 motorcycle oil and the shudder went away shortly afterward.

Most likely it's carb sync. Unbalanced carburetors cause unbalanced power pulses at low RPM, particularly when the engine is lugged, which sets up vibration in the primary chain.

The oil and carb sync comments are both worth considering. I'll endorse what was mentioned earlier about keeping the revs up, in another thread you mentioned a Sporty "Back in the day" Four cylinder rice burners don't have that same stump pulling power down low like you where used to, it was one of the things that took me a lot of time to learn to get past. These engines like to REV and are just getting into a decent power range at the same RPM we where used to having to shift at in order to avoid catching a broken piece of top end in the nads. I keep my bike above 3500-4000k most of the time, once you get used to that you'll love what your right hand can make these things do, especially in the twisties.

Going thru and changing oil again. Was doing a clean out oil for a couple hundred. Put the synthetic motorcycle oil in. On trip to town this morn for bfast, packing mama, it seemed not as bad.

The 1800 and 1500 did not have to rev as much for take offs etc. Been over 20 years since on a 4cyl. But they are alot more power in the grip.

Thanks all for the input.
