Needle jets

[D.T.]

Are there more options for the 1980 GS models? My 850 has only one option as far as I know. No different positions on the needle, just one. I'm removed the upper plastic bushing to get the needle up a bit and it helped. But getting the needle higher would require grinding plastic off the lower part of the retainer above the needle jet.

I spoze I could just get the needles. Interesting info though.

Canadian needles have slots for adjustability?

Yup Canadian models have adjustable needles and no cap over the mixture screw. You totally removed the plastic spacer and its still not rich enough What setup are you running? pods, 4-1??

Allens in the UK may have alternative needle jets. You'll need to quote the code on the existing jets.
Won't be cheap though - I got a price for richer n/jets for the 1000, and finished up making a set...

The bike I'm working on is stock. Except someone put 170 pilot air jets in. I think the 190's would be fine since it starts with little choke. But maybe they were trying to richen up the transition circuit? I'm having some bogging issues right off idle. New intake "velocity stacks" are coming in this week. They weren't sealing to the airbox worth a damn, so maybe that is the problem.
