Engine Bogging when cruising

[robertseward]

When I am cruising along on my 1981 GS850G I get a bogging only at around 50MPH after it warms up. When I roll the throttle it picks up eventually almost feels like a grounding feeling. Anyway It starts instantly, runs beautifully the plugs look nice and lean the airbox looks like it is sealed good I put a new electrosport r/r and stator in it last year. Any ideas
would be appreciated.

Thank You

Plugs shouldn't be "nice & lean". How are you judging that??

I guess I am trying to say the burn colour of the plugs are a nice sandy brown.

That may be true, but unless you're doing specific circuit chops, that is just an over all burn colour, running thru all the circuits. Your pilot circuit (which is generally where you cruise in) could be rich, the main could be a touch lean and the needle circuit close to right, and you could end up with a good looking overall burn... Try a chop in 2nd gear, mid rpms, minimal throttle twist (like an 1/8 turn) ride like that for a mile, then hit the kill switch and pull off the road and pull the plugs...if they're not sandy brown, but a lil dark, then you need to back off your screws a half turn or more..
