Boo hoooooooooo - Betty has BANGED!

[Joni]

Oh dear... sorry to hear this Cath...
Is she repairable? Or dont you know yet?

Hope it gets sorted real soon...

[pete376403]

Details needed - when it went "bang" did the back wheel lock? If it did lock, did the wheel start turning again when you pulled the clutch? (ie are we looking at a motor bang or a transmission bang? Did oil come out of the motor? (This assumes there was some in there to begin with...) Will it turn over on the starter motor and, if so, does it make bad noises, that is, worse than previously? (Don't be too persistant about this, if it won't turn, don't keep trying).
Let us know, might not be as bad as you think.

‘pparently it feels ‘grounchy’ when kick lever pushed down. Needs inspection. I’d offer Cath, but I need to find a house to live first, maybe when things have settled down. Someone?

Hope the wee Honda is up and running again soon CSL.

I think I can lay my hands on an entire CB250 bottom end including gearbox. How much would you be willing to spend, or do I buy it and we pass the hat around? I think CSL deserves our support on this one,.

Happy to help a worthy cause! Can't let that new paint go to waste...

[Paul in NZ]

I'll help!

I'm not an hexpert on Honda motors (or anything except excessive consumption and bad manners) but before purchasing a bottom end and bit of a rudimentary investigation into the problem could be in order. ie We might end up with 2 good bottom ends! (and I'm always VERY suspicious of engines missing bits as it assumes it had a problem some place / time)

If we can find a serviceable unit....

We could have a transplant-a-thon at chez Nuttridge. A round the clock spanner twirling session until the job is done. Rabid teams of KB's fuelled on pizza, coffee and beer listening to dodgy music ripping out the old donk and installing the new...

Then..

With the beast strapped to a table we wait for a thunder storm and winch it up to the tallest part of the tower (the bit the lightening always hits), practise our maniacle laughter and Igor stands by to.. oh.. hang on thats a brain transplant..

But we could do it in town at someone else place too..

Cheers

Mr Paul in NZ has a point.

Most likely bang on a motor that age is probably the cam chain going, leading to the valves shafting the piston.

Bottom end could be OK in that case. (might be munted too of course. Mr Conrod often objects to Mr Valve impeding his upward progress. )

Justa pure guess of course, but cam chains are always the weak point on OHC engines.

[F5 Dave]

Or if you're real lucky the starter motor has lunched itself. Best to check.

Well said, Igor...

True Ixion - the CB250RS is an XR250 motor,famous for camchain stretch and inlet valves contacting piston with lots of bent metal.Bottom ends are good,I'd say a top end is required....or a chain...or...who knows.

It's an XR250 engine you say.... very hinterestin'

Would say.... a 'bigger' XR engine fit relatively easlily?? Maybe??

[F5 Dave]

Yes, that was a common mod. Had an article on it somewhere. Problem is XR500 engines aren't exactly common or cheap nowadays.

[James Deuce]

Righty ho. The CBX250RS with missing head has been sold over the past weekend. For $130. So that idea is out.

My brother in law has a line on an XL250 and an XR250, so I'll report back when I find out what state they are. He's a motorcycle mechanic btw, and the CBX250 was alright. Thanks for the vote of no-confidence.
