Fortunately the instructor chap has a whole stable of bikes so he seems to know what he’s doing with his. I on the other hand do not. The little CBT bike would start no stress, but the 600cc needed a long time to warm up before riding.
Didn’t get out today but put the Suzuki idling for a while to see where the revs would sit.
There was definitely an air leak - the jubilee clip that should have been holding everything tight on the back of the carb was dangling about loose! I tightened it up, and managed to get it to sit around 1500 and not cut out, but then trying later it stuck at 2000 and if left too long idling there’s a ting ting ting sound from something in the thingy or other. Goes away when pulling the throttle a little.
It would be nice to get a lower idle and more defined needle movement, as it drops very slowly after any pull of the throttle. On the road it’ll be totally different I suppose. So long as it doesn’t go through the roof and refuse to drop.
I was trying to see if changing the choke was making any difference, but the choke seems less than smooth in its operation. At least it starts up properly now, unlike the other day.

I got the old carb version of the yamaha 125 you did your cbt on and it's pretty much impossible cold, I could never get anywhere in a hurry. If I can get it to idle cold with the choke off it cuts out as soon as I touch the throttle and it hates riding with the choke on or half.
Morning / after work routine is firing it up full choke, then go get dressed up. Come back 5 mins later and I can turn the choke off and it'll behave fine.
