Ok, will look at new jets but for now there are many other things to fix...and by the way I didn't find them singularly on internet, I found dynojet kits but from 70$. Don't you think that maybe I could let mine stay in solvent and they could clean a bit? Like winegar for the rust of the gas cup, or Coca-Cola or diesel ..? And the leakage problem was definitively fixed, we forced the small piston closing the hole where the gas comes in the carb, cleaned it and the hole and applied a bit of motor oil, no more leakage at all. Before it was stuck in open position...The motor seems to run fine, like has always run or better, maybe a bit lean...Those jets look filthy, should be shiny. I would get new ones, cost maybe $6 each from a shop. Your leaking problem is probably the float needle seat. Either some gunk is stuck on it holding it open or the seat has dry rotted and needs to be replaced.
Yes, replace the entire clutch cable.
I don’t think so. If I remember right, the brake rotor hub is a larger diameter than the rest of the axle, meaning it all has to be removed from the left side.I'm thinking about trying with the other one, is it possibile to do the same job working on the rear right hub?
