Fellow M'bikers of the world, I have a dilema.
Let me run it by you, to get some opinions.
I have 2 ht engines.
Engine No.1 (F80b) is only a few months old, but recently began making fairly loud geartrain noises on the clutch side, & upon investigation I found that the crankshaft has about 1.5-2mm side 2 side play, & there is slight gas\oil mixture on & around the magneto, not a whole lot, but enough to see its there. So from my homework here on MBc, I assume the bearings are shot, & as far as i can tell I need to split the case in 2, to replace the bearings.
Engine No.2 (a $10 unknown origin special) needs a new top end, but the bottom end seems solid, although it looks to be a few millenia old!!
Is it ok to take the top end off engine No.1 & put it on engine No.2???
Should engine No.2 be considered a ticking time bomb because of it apparent age???
Or should I stop being such a cheapskate and rebuild No.1??
I will be ordering a new RSE, either 49cc hp stge 2 or a 66cc hp stge 1 in the coming weeks for my cruiser build, but I would like to keep my old thrasher alive for the occaisional dirt track thrash!!!
Any sugestions/advice would be greatly appreciated as I'm travelling by pedal-power at the mo!!!
Also any recommendations on the RSE 49/66 will be taken on board.
Thanks, Chris.......
