K1200 Gearbox

[TomL]

I think that the main problem would be cleaning all the pieces of swarf out of the engine. Would the swarf have already travelled to the grankshaft bearings? Would have to be a total stripdown.

Time for an engine and gearbox transplant. Bad luck Chris. Hope you get it sorted one way or another.

Unless a donor bike can be sourced VERY cheaply, the transplant option makes no sense to me. Even more so if the donor bike being looked for is a 1300. The improvements on the 1300 were a lod more than a few extra CCs, Given the work involved I'd definitely be looking at finding a K1300R then using the 1200 to be the donor bike for any of the customised bits that you'r really attached to, scrapping the rest of the 1200. It'll likely be less work, no more expensive, leave a bike that's better over all and will still worth something.

Except you still get the 12 gearbox which Chris is saying is a suspect design. One wonders what it would run like if it was just a 1300 engine and box plumbed in with no ECU changes etc.

As to Tom's comments about the swarf, if it is merely the shift levers that have bent then there won't be any. Did it actually explode with lots of whirly bits going graunch Chris, or just get stuck in gear?

And yes, being a cassette box means that it all just pops out as one unit rather than having to strip it all in situ which would mean an engine strip.

Anyone else done it?

Sorry Brian,  but if the first para of your post is a response to mine it makes no sense. I'm suggesting scrapping the 12 and getting a 13, gearbox included.

There was some initial graunching, but stopped that with a double clicking from 4th to 6th, after the stop at Shobdon, first time I took it to sixth it stuck that way and hasn’t moved since, biggest pain is having to clutch it to even move it in the garage.

Re a solution...too be honest their are quite a few ranging from scrapping it to heaven forbid fit a 1300 motor and the hassle with the software, as I said in the other post...it’s only when you go searching for video’s etc about such..the amount of great info is astonishing.

Currently the front runner is a 1300 gearbox and clutch, how one acquires such...now that could be interesting, but at the same time if I get a phone call saying how much for the bike as is could be another complication...because the immediate answer wouldn’t be yes i’ll Sell it...just something else to think about.

Ah, I thought you were suggesting getting a 13 for the gearbox and doing a transplant.

Woo boo after much huffing and puffing finally got the box into neutral..at least I can move the dam thing without the clutch, and shows all the signs as per the YouTube vids of being selectors.

[TomL]

Time to remove the gearbox and take a look.

[chriscanning]

Thank heavens for all the individuals who take the time to post YouTube vids which has been most enlightening, even those that show the problem without the solution, and as bizarre as it sounds already had to threaten the individual who’ll strip it  ...that I expect to pay as a punter, cuz I know he’ll want to do it for peanuts.

Anyone got a link to priming the gearbox oil pump... cuz that looks currently to be the only missing link.

[TomL]

It explains how to do it on the Reprom 11 41 000.

Looks like you need to pressurise the oil tank and crank the engine on the starter without it starting.

[Phmode]

Blimey! How do you prevent it from starting?

[chriscanning]

When i’ve worked out if the 1300 oil pump is a must and sourced a motor, will give priming the pump a tad more thought or my mate but thanks Tom and I do have the eprom...all of which doesn’t close currently compared to the 4 blokes I have at the house sorting the roof out.   

How the hell I ever found time to go to work...i’ve Absolutely no idea!!!!!!!

Please don't forget to take a few photos as you get it apart, for the next unfortunate soul that may need them.
Cheers!

And put a leek at the bottom of the replacement, for good luck. Or is it an onion. I think my grandad used an onion.

You have to connect up to the diagnostics and carry out a crankshaft sensor test. This will crank the engine without starting it. I presume this can also be done with a GS911.
