XBR 600 first ride

[blew]

The bike was always running rich with the original carb,perhaps the needle and jet were worn.The Dominator carb was a straight swap,with a bit of fiddling to get the cables sorted.I left all the jets as they were.The plug is now a much better colour,and the bike seems a bit smoother.I haven't noticed any great difference in performance.I used the original airbox and filter.The main jet in the carb is a 140,and it seems fine;I don't know whether to try anything else-I wanted smoother running,not more performance.So far,it hasn't stalled once on tickover or on decelerating,which is a definite improvement on before.The tickover used to be erratic,but not any more.

Ahhh... XBR erratic tickover - there's a well-worn thread.

My only observation is that although the Honda revised settings and pilot jet help matters, all of my bikes have been much better after having their valve seats reground.

The Dominator carb is the same bore as the XBR carb (39mm),but the jetting obviously suits a 600 better than the XBR500 carb.There is also a clever little lever that opens the CV piston at small throttle openings,which I think is responsible for the smoother running.It behaves much better at idling and lowish revs than the XBR carb,and the plug colour is a nice brown,whereas the XBR carb always produced a black plug.
