Does...it fit?

Does a k8 engine fit in a k6 frame?
I'm afraid that my k6 engine will soon need a rebuild and would be cheaper for me toss a k8 engine in to it...

Thanks guys

I'm pretty sure the k6-k7 frame is different from the k8 generation. Not saying it won't, but that's not a good start.

Thanks for the reply
My engine has now 70000 on the clock
And it's starting to make a funny rating ish noise from the lower engine side
The engine has a new cam chain and valve clearances are done, compresion is half bar under the minimum, one cyl could use a replate (obviously if done...all are going to get done.)
Don't know if it's really worth to rebuild these engines of get one second hand...
Any advice?

Two sides to that coin. Say you get an engine with 12,000 on it. Maybe it was well maintained. Maybe it wasn't. Maybe it had some hack engine work done and is a ticking bomb. You might get a jewel, you might get junk. Plus, you'll need to get the wiring harness and ECM from the newer bike too. Add to that any wiring pains for mismatch between harness, engine, and chassis wiring.

Or, drop your engine and have it overhauled professionally. A rebuild from KWS wouldn't be too expensive (except for the shipping) and you'd get a known good engine that slips right into place. Give it a good tune and let'er rip!


And then you can take the dirty side. Say your bike is worth $2500. Take the money it would cost to do the swap and you've got at least $3500 to throw at a newer bike. Around here, I can find L3 and L4s for that. Granted most of them are in rough shape, but in the long run you'd be out ahead. But, that jewel or junk rule applies.

Thanks for the update
I'm in Spain and here the guys that rebuld engines are easy asking 3k € and I have seen some work of different guys around Spain and most (of the ones I know...) of them are...the brown stuff you leave in the toilet after a strong black coffee in the morning.
I could do this job...but better pay the dollar and get some sort of warranty...:/ For 2 k I could get an engine but it is as you say the 50 50 game get a win or get shiat...
I know once engine is out it would go for
- all the shells
- replate and rings (pistons?) Here the replate is done by airsal and the stuff I hear from them is not good.
-cams also show some wear, when I first bought the bike de dealership recommended to change the cam chain tensioner...so that was done just to find out years later he had put the gasket the wrong way leaving the oil intake blocked there.(nothing to do with cam wear)
Oil I am using is motul 7100 10/40
No oil consumption,interval of oil+filter change 4000/5000km maximum.
Original oil filter only.
-check valve stem play
And so on what Haynes manual would recommend.

Down to all this, is it really worth to keep a k6?

Thanks for reply and help

Could you find a complete k5/6 from a wreckers and part out all the bits you don’t need, keeping the engine?

If I were you I’d either get another engine that will bolt right in, or buy another bike and sell yours (either as a “project” or part by part).

If you buy another bike, get the frame, engine/transmission checked before spending the $$. At least then you hopefully won’t get a lemon.

Good luck!

Does someone hears of AHL ? I am looking for engine con/crank bearings and these show up, material aluminum alloy ?????? :/
Where could I get some for the entire engine without a mayor pocket breaker?
Thanks

Know of any good one?
Apart from crank and con shells and rings, what else should I look to do?
Plating here is momentary not an option...
