I have a 99 KTM 125 exc that runs fine over flat ground but is bogging over bumps plus fuel is leaking from the float bowl when the bike is on the sidestand. I'd recently been messing about with the jetting on the bike and changed the float height (which obviously seems to be the problem here) but what I find strange is that I set the float to sit perfectly parallel with the carb, I used the blow down the fuel line technique. So my question is should the float level be set lower at an angle rather than parallel or is it just a case of experimenting to see what works best.
My other question concerns the seal where the kickstart shaft goes into the crankcase. This seal seems shot and blows back a small amount of oil. It's not a serious amount but is this normal on KTM's? Can I replace it easily and what effect on performance would this leaky seal have? I'm going to trade the bike in for a 2002 200exc in May and don't want to give the dealer any excuse to knock down the value of the bike.
