For half of a century, I've used ATF to lube the chain. After a ride I wash the bike than I generously lube with ATF, I wipe of the chain before leaving for the next ride. I found the lightness of the oil penetrate the rollers and push the mud out. Only thing, don't forget to put something under the bike.
I do agree with you Jon v8 that the Mikuni that come '' stock '' on TY are the best and I would never swap one for another make unless the original was worn out and I would not be able to find another original TY Mikuni, but the Mikuni VM are not the ideal replacement for a TY 250 in my opinion.
A few years back, I replace a TK carb on a model 434 by a VM32, I never could make it running well. I'm not saying that I'm a Mikuni engeneer but I know my way around them, if you don't find a rebuld kit, you should consider OKO. The comment are very good.
When I use ATF to try to improve a clutch, I change the oil after acouple of hour of riding 2 or 3 times before deciding if I need to change the plates, sometime it work sometime.......
I think that it throttle response is a personnal thing, for me no weight at all on the flywheel of my TY with an A model cylinder is the way I like, yes quick response but also the motor '' rev down '' faster when you shut the throttle. I have to say that I ride more in the mountain than I run trials event.
Here in Canada The A model had the sidestand on the left and the bracket was welded to the frame, on all the other TS it was on the right side of the bike and attatch to the swingharm.
I think that is body and skill are often the best guide for that choise, I mean even if he is tall and muscular but not very ''at ease'' yet on a bike go 125, he might be small and skinny but confortable on a bike than the 250 might be a good option. Don't look at him with a father's eye to choose and if you have a chance, have him ride a 125, he also have a say on the bike he want to ride.
I was riding yesterday, and as usual I used the first finger. Just for fun, I tried the midle finger for a while. It realy does not work for me, funny thing, I only use the middle finger for front and rear brake when riding my bicycle witch I ride a lot .
What I would do in order : Take the pads out check them for exess dirt or oil, sand them on a flat surface, clean the disk, and do the cold water treatment: ride and drag the brake untill the disk is hot then drop cold water on the disk.
I could give you my setup but I don't think that your the same height and have the same arm lenght ..... All that plus the handle bars position, the type of levers and so on. I srarted with a neutral setup and reposition all the control including brake and shifter so I am confortable.
One other thing, you could copy Tony Bou setup, but I don't think you ride exactly like him, ( that's what I told myself when I setup my bike )
I use Motul Transoil Expert 10w40 in my ST 250, I have very little grab when I ride the bike regularly. I also had until last year a TY 250 and 10w30 motor oil was doing the job ok, after rebulding each motor ( I had a few ) I would drain the crankcase, fill ( 1 liter ) of ATF ride for an hour or so replace the ATF with 10w30.
