Engine for DoctorLaw!!!!!?????

[DoctorLaw]

In an attempt to uphold my position as purveyor of lucky white biker heather on the site I appear to have killed a second BMW. Good news I imagine for some of you but a bit frustrating for me - not least because it stuffs my plans to ride around the Highlands following a mobile cinema next week.

I will let PD explain:

" Gentlemen,

I bring you bad news of Roslyn's bike. Fresh from having tried to kill everyone who tried to ride it, it then got a stuck float valve dumped down the bore for about 60 miles thereby washing all the oil away, so that - according to the garage - the bike now needs new rings. For good measure, the rear brake is jiggered too.

I have not seen it running since Sunday night so don't know if it is smoking, and I don't have a compression tester to check it. Assuming the garage is right though, Roslyn would rather not pay for ten hours' labour before even finding out if the bore is shot.

The proposal is to get it out of the garage and into storage.

Is there anyone on this thread or elsewhere who's prepared to check the compression, and if it is unacceptably low, take the engine apart, inspect it and see if it can be fixed? Ros'd help out and learn and probably stand lots of beer. "

To answer his questions - it was smoking and there was no compression and yes I would stand lots of beer.

The latest suggestion is to buy a new engine and I am feeling a little overwhelmed, given I am hanging on by my fingertips in my understanding of the technical aspects of what is going on and what it means. I've found a 2000 engine with 4300 miles on it for £550 on M1 Salvage & Breakers - thanks to Rog - and would welcome comments on the merits of this plan versus (someone) dismantling and rebuilding the original.

If it helps I promise not to go anywhere near bikes belonging to anyone who offers to help, as bits will inevitably start falling off or exploding just because I am in the vicinity.

For what it is worth I also still think the offroad fun (if admittedly not financially) was worth it. Thanks in anticipation of continued XRV chivalr -ous-ness-ivity.

Jeepers creepers Ros.

Now what the Doctor really should have ordered was Boboneleg and AlanH's old bike, currently for sale for just over £2,000.

This is a superb example and I'd buy it if I didn't already own two of them (both mine are inferior to this one).

We could find a way of lowering the suspension and the seat, but I guess you'd have to sort out the full test to avoid restricting it.

I doubt even you could kill and Africa Twin RD04.

Roslyn, I have all the time in the world right now,but unfortunately I'm still not up to "spanner strength" . I do though, have a feeling things will turn out just fine,if I know the XRV'ers. Should you eventually need to get the job done at a garage.I can recommend a garage in N1,where the guys are good friends of mine.Although they may introduce you to areas of the English language most of us have never visited,they are exceptionally honest and cheep too.Let me know if I can help.

Damn, sorry to hear about that Ros! Am sure it is not just you as my down pipe has fallen off twice now, rather upsetting for a chap as you can imagine!

I'd go with the new engine or new bike option myself just because I need to place so much trust in my machine.

Two bikes broken, both F650's.
Not looking too good.
If you get the newer engine, it is not too hard to swap them then at your leisure get your engine rebuilt, and keep it as a spare.
Are you sure it is not the restrictor kit that is doing the Damage?

If you want to change the engine I could swap it in a Day or Two.
