My diadora muds arrived today

try diadora mud boots ,

At 2 thou let it warm up before you ride it otherwise it may nip up and use a good 2 stroke oil Dave

one Dave

That thick black treacle is un-burnt oil so its over-lubing the barrel. Either re-adjust the autolube or blank it off and mix in the tank and use a good oil or a fully synthetic one that will burn off better thou they all leave some unburnt oil behind Dave

The lobe rests on the casing at around 1 o'clock which is where the kickstart should be (and at a position that you often hit with your shin!!!) , if you put the kicker further forwards the lobe will puncture the mag housing case when you kick over fully. Dave

I re-bored my 247 to 00.003 thou, dont know the metric as i only bore in thou. Dave

Fit the bearings flush to inner casings then the crank, fit crank into the mag side first as the gearbox should rest that side then fit clutch side next. Dave

I use atf in my mont 247 clutch and ep90 in the g/box Dave

As you have got the new piston i would get it bored Dave

Hi, my 247 runs on a bultaco piston without any probs and i did the re-bore. Go get it bored out and also check the small end and big end for any play Dave

Hi, bearing size is 6205 for both sides, you must use C3 bearings for heat expansion, Dave

If they are 6005rs then they are the same. Dave

Just got my old mont 247 piston and the ring pegs are at the front around 10 and 2 o'clock as were the bult piston. Piston fitted had a rear window and 2 small front holes, made by GPM of Italy. It works fine Dave

I would put a mt43 on the front also, my 247 montesa handles fine with them and a good front will stop you sliding sideways on a sharp up-hill turn Dave
