2xmonty

The sound of good reasoning thanks I would rebuild it but the parts are hard to get hold of. I should have looked for a 4 stroke engined bike in the first place because I would be using it on road throughout the winter months as well as a bit of light trail riding. The 248 starts 2nd kick has good compression but smokes a lot which is not too good for the road, the bore is good carb rebuilt with original spec parts just cannot get my head around it so will probably sell on. Thanks for the reply Got a pair will fit and try again.... Cheers

That looks a pro job... I did not think of a C15 motor its just my mate has rebuilt several small brit single engines with higher quality bearings and upgrades. He did suggest a Triumph 350 saying it would fit in fine, he has built Tribsa's and the like in the past. The alignment is out of my league so only going on advice really. The Montesa 248 engine is difficult to get some parts for (common bottom end with 349) so looking to use this long term, I would buy a 348 or 349 engine if one was going but you dont see them often. Thanks for the reply

Hi all I have a 248 that I cant get to run clean after much effort so my engineer pal suggested fitting a 250 BSA engine in it. Has anyone had an had a Monty with a four stroke motor fitted, I know it may be sacrilege but will be using it for green lane work and after having new forks (chromed and new seals) new rear shocks new headlight and frame paint wheels rebuilt mudguards it seems too good to stop here. Maybe not the best choice but I had a 348 years ago that was good for trail stuff, if not could sell and look for a 4 stroke. Cheers Noel
