Anyone out there have experience with this?

My RGS pulls very well at higher RPM, and is great on the open road.
However, she surges in town between 30 and 50 km/h (20 - 30 mph)
By surges, I mean she is really jerky, even if I am very careful nt to move my throttle hand.

Any suggestions as to how to fix this?

Regard,
Steve

If it isn?t ignition or timing:

One possibility is that it is running too rich in progression. The engine is ?hunting.?You haven?t mentioned any popping on over run so it probably isn?t too lean.

Easy way to check is as you are coming into a town turn off the fuel tap. If it gets better before the bike really starts to starve you have your answer. If you are running dellortos then find the best idle speed with the mixture screw. If less than 1 1/2 turns out this supports this theory. The 2 main influences on this are the pilot jet and slide cutaway.

This is generic advice, not Laverda triple specific.

I don?t know mikunis either so I?ll butt out.

Rod,

I kind of think your suggestion is right, need to get some smaller pilot jets and try it out - thanks. I do have a set of new slides, might be worth a try as well.

Clem,

The exhausts are pattern stainless Laverda, purchased from OCT. Nothing radical, but look & sound sound nice.
Inlet system is standard.
