Finally have the rocket going and all in one piece. Now tidying up all of the fiddle bits you leave behind just to get it fired up. I seem to have a problem with mismatched carbs. The bike started out as a 73 R75, then due to storage issues from the previous owner, it would have required a complete rebuild to bring it up to scratch engine wise. So a78 r100 motor was sourced plus wiring loom tank and seat. Many years later it's a goer and I've a suspicion that the bloke I got the carbies from might have been telling porkies. He said no worries mate these suit a 78 r100.
The right hand side is a 64/32/306 from an 83-86 r80gs and the left side is a 64/32/347 from an r65ls. Yeah they look the same. They appear to have the same main and idle jets as an 81- 84 r1007. The r65 carb has the different needle arrangement, the r80 carb has the push and turn adjustment method along with no jet arrangement in the corner of the bowl that the r65 has. Only a brass fitting with a hole which I imagine is the same as the jet measurement.
I know there are different mixture settings and whilst the bike idles ok,which after so many years you are tempted to ignore until it really pisses you off, is this a situation that won't take too much to fix. Rather than scratch around for suitable carbs.
