Hello,
My 77 850T3 was mostly off the road for a couple of years due to schedule and a new baby and some deferred maintenance i needed to do, but as of last summer I got it all set up and back out on the streets. This year, I'm noticing that it has a sputter, or kind of bogs down a bit while it is under load. this happens above 4K rpms, but tyically under 5K. I don't take it up that far in the revs all the time, but just want it to pull smoothly all the way when needed and want to make sure I have it running right. Does this sound like a slightly clogged jet or is there anything else i should look for? Hoping if it is a dirty jet I can run some sea foam and get it passed through, but if necessary I'll pull the carb and clean.
Thanks for any help,
Rob

Try just dropping the bowls...loosen the clamps and rotate if need...remove slowly to see if there is any crude in there

I had similar symptoms on my '78 LM. Turned out the floats were leaking.

Sounds like fine grit clogging your main jet. The real powder stuff. Take the carbs off and use some spray carb cleaner. Disassemble and clean.

The carbs are the best bet, but on a bike that age after sitting up it's possible that the ignition advance is stuck, you might want to check there. Just take the cap off the distributor and see if you can turn the points cam against the springs. Or verify timing advance with a timing light.

Ignition Advance was the culprit. Easy Fix! Now the bike is running like a champ again.

Heh Heh what's that old saying," 90% of carburetion problems are electrical ". :evil:
