Montesa Decompressor Position

Featured Replies

Hi another question regarding my 247, It has a Decomp fitted, but it is in the vertical position with the plug at the 45' angle position - is this correct or should they be reversed?

I'm not aware of the actual combustion chamber shape, but suspect that the central position would be a better place for the plug for a uniform burn

Should I swap them over? (I'm assuming that they are both 14mm)

Originally the plug would have been in the central position but in practise, it won't make any difference to the way it performs whichever way around they are fitted

Thanks Woody, I wont disturb them then and leave them as is (It certainly makes access to the plug easier this way round - which will be why someone has swapped them previously it seems). Popped a new plug in earlier and it fired and ran first kick so getting somewhere with it now :thumbup:

Only had what fuel was in the pipe as got tank off at the mo, so couldnt tell much more than that but i've got most of the weekend free to work on it so hopefully can get a blast around on it soon to check everything else is in a serviceable condition
