thanks for the inputs, gents.
the problem may be moot. i just recieved my mukini single carb. as soon as i work up the courage to remove the amal and replace it with the jap unit i'll post results.
..
any suggestions on this project?
Did you get a Mikuni Kit with manifold and filter pre-jetted for your bike from a dealer who set it up?
If yes you should have a pretty easy go of it. Install and try it out.
It should have come with instructions for adjusting carb.
No tickling required or even optional on this carb.
Remember Mikuni doesn't have a choke but a seperate circuit that when the lever is up acts to provide a fuel rich air supply.
It only works when throttle is
completely closed and don't crack it when engine first fires or you'll put out the fire.
I use my "choke" most of the time up to maybe 60 degrees. If no choke maybe 1/4 throttle.
There is an adapter kit that provides a cable from the "choke" to the standard handlebar lever. I like it a lot rather than have to fiddle with the carb with my hand during fire up.
I had a problem with my Mikuni staying stuck full open. Lucky to have a kill switch as I was going 70 at the time and winding up in third gear!
Pulling clutch would have blown engine for sure.
After stopping and checking everything was ok. Apparently high velocity air flow is able to hold slide up.
I found out on this forum that this had happened to others with the 34mm VM. Solution others used that I did was to add an Amal spring in addition to existing Mikuni spring. Makes throttle a little stronger but not a problem but hasn't stuck since.
