If you balance the carbs first, then adjust the mixture which as you say
will increase the idle speed you now have un-balanced carbs again. I'd go
the other way round.

| Mike, The only two screws in question is the big one (idle speed) and the little one (mixture). The first adjustment is to adjust the big ones so that you balance each cylinder. You want each cylinder to work the same. You do this by |
| the idle speed. I would recommend that you use a carb stick to do this. Once you have balanced the carbs and set the idle speed that you want then you go to each cylinder and turn the little screw. In will lean the |
| and out will richen it. The idea is that when you hit the best mixture the engine rpm's will increase slightly. It is important that you wait approx |
| seconds between turns as to let the engine adjust to the new setup. What I do is go to either end of the turns where I feel the engine start to run off. Then I narrow in the range till I get it just about right. Once everything is set you can adjust your idle by turning the screws the same amount (in for increased idle and out for a decrease). I would also recommend that you take your bike out for a good run and then have a look |
| the plugs. They should be the same colour....tan. While I am on that subject....I replaced the o rings on my choke |
| I'm not sure if it will make a difference but the ones that were in there were quite old and worn. I figure that old ones might richen the mixture |
| be causing your problems. Sorry about the long winded post. Let em know how it all works out....Ian
