Forget about plugs when checking the idle speed/slow jets.  And engine speed is a second order effect.

Wrap some tape around the throttle/body and use a sharpie to mark 1/8, 1/4, 1/2 3/4 and full and put a small piece of tape with mark on it as an indicator.

Starting from cold should require choke.enricher, so just get it started and get it warm.  Air screw should be between about 3/4 turn out and 1 3/4 turns out.  If it works better with the air screw further out, the pilot jet is too large.

Once you get it to idle, find a nice long road with slight hill and ride it wide open up that hill and do a plug chop. Do not ride home with the same plugs in.  Take the plugs out and examine them or swap in a spare set and take those home to examine them in safety.

For main jet you want the center insulator to be white.  Mixture you read where the insulator meets the shell. Look for signs of pepper spots (detonation) or cement boil which are signs of overheating from lean mixture, wrong plugs or too much ignition advance.

Once you get those dialled in, try 1/2 throttle to 3/24 and move the needles up or down to change mixture strength there.

Thanks guys will def get into it This next week. Perhaps my 30 pilot is a little large then because I think I got max rpm out or 2 turns out with the air screw. I have a 25 I could give it a shot and see if it's better.

Ax,  knew you'd get her going.  Good deal on the R60- can't wait to see it.

It's been a long and rusty road but I think i am at a good stopping point on this old girl. She runs pretty good right now once you get er going still needs some fine tuning on the carbs but I got a couple gaskets changed put some High grade honda oil in and it holds it like a motor should. I spend alot of time just staring at it in my basement. lol. Still got a few things to do with it like rear sets, I'd like to upgrade rear shocks, gonna have to rebuild the front forks this winter and Get new Rubber. But Here it is.

Looks great!  So now we can ride!  I'm out of town this weekend and work next, maybe over Labor day weekend?

Very nice, now please add a front section to that rear fender to keep rocks, dog shit and water off the engine and out of the filters. Racers all have rear fenders/rock guards on clean dry tracks.  How is it that cafe racers have a force field to keep that stuff at bay?

Can't do it teazer. She is just a dirty whore i guess who spreads her frame for anyone.

Dropped the needle down 1 notch (to lean it out) performance improved a good deal. May try to take it to the top notch of the needle and see how it feels. Also put the 25 pilot in. It is better off the line and the air screw adjust is at 1 1/4 rather than the 2 turns for the 30 so i feel that's pretty solid. Running pretty damn well now. The 145 seems to be pretty great at the top end so i am not gonna mess with success. so my setup that i am running now is.

VM30 pilot: 25  -needle 6f4 -159 p5 (needle on 2nd clip from top), 2.5 cutaways,  145 mains.

Prob gonna stay that way for awhile
