M750 Rear Cylinder Removal
Hi,
I'm about to lift the rear pot on a 2001 M750 as it's leaking oil which is somewhat vexing me. Is it possible to do this with the engine in the frame or is it a frame off job? Cheers |

Maybe not a huge help. On my 2003 1000:
it's possible but I need to remove the pipes and suspension rocker to clear the rear exhaust studs. There may be just that fraction more space on a 750, not sure sbout the older suspension arrangement, a quick look downwards with the tank up should make it clear. |

Rear cylinder comes off with engine in the frame no problem with the older (hoop) suspension models M600/750/900.

Jerry did his 750SS recently with the engine in the frame for the same reason. I know he was plagued with a persistent oil leak which I think was eventually sorted after the 3rd attempt.
Perhaps he will post with his tales of woe?

Excellent.
As well as being handy info for future reference, this is further evidence that the early monsters are one of the easiest bikes to work on. |

if it's the head, try lapping it to the barrel with some valve grinding paste. if it's the base, more 3 bond but double check it's not a damaged crank breather before starting surgery

Does it have its full complement of o-rings?
See slob's diagram at post #13. http://www.ukmonster.co.uk/monster/s...ad.php?t=54988 |

Thanks all, I'll order new o rings from Moto Rapido tomorrow and tear it down tomorrow eve.
I can't believe how Micky mouse the base gasket o ring seems to float on top of the base gasket It's not the breather as that's new (first thing I changed). I'll also lap the head. Cheers |

Oh, is it worth putting 3 Bond on the head gasket joint?
