So - nearly there, so thought I'd post some pics of what an Engine swop involves - plenty of work, but doable at home and good a challenge in project management
! Engine popped so bought a 50k miles replacement " Here's hoping it fires up!
-
Very cool!
Carry on.....
-
I can envision clamoring here for the polka-dotted work-seat/footstool. Amazonians, take note!

Awesome - I picked up a spare k75 engine/rear and have been thinking about looking through it...
Take lots of pictures for me!

Learn to do that and the TSA will hire you on the spot. Good part-time work!

Yep - last night put Injection back on and wired in Computer now that it's turning over again safely.
Couple of my sons mates - 3 in Total helped me move the Frame back onto the Bike...
Found a connection issue - fixed, though I think it's for the ABS which I removed including cutting out the Wiring Loom - that's 12 kilos and future trouble removed. Yes, I know - The one day it works, it'll save you... way over complicated for a 1991 Bike... ABS was working but couldn't be bothered with it for all the extra tech - removed both relays and Pipes front to back - leaves me needing a new Front Brake hose and Rear...
Found the Temp sensor in the old Engine and wired it in also last night...
Fitted Rad, Pipes and filled with Anti-freeze / Coolant mixture - here's hoping it doesn't find it's way into the Oil this time round.
Old Engine is sitting in the Corner, sulking, stripped to bits awaiting further investigation for those that read the sorry tail of it eating it's coolant.
Stripped Pump front and re-sealed with Silicone and re-fitted.
Most useful Tool - Wire Brush
- Jeez, 30 years of muck and crap on every bolt - wire brushed, stripped and cleaned every single nut and Bolt including Centre stand... treated myself to a new one this morning
Some more pics of Engine on Bench plus some others.

It's fairly straightforward with a Dry Garage and Home Tools - Undo everything, wiring, cables, frame Pins - pull et Voila 2 big bits -
1. Bike Frame and Front - Fairly clean
2. Engine, Gearbox and Drive plus Rear Wheel - full of muck and crap from 30 years on the road and British Winters
- lots of buckets and boxes for bits and a Wire Brush and some Gunk / DeGreaser
- most time so far is all the cleaning and painting of the bits, plus pulling the frame off, then walking it back on.
On the home run now - hope pics are useful..
-
Pump looked pretty good inside compared to the old unit on original engine.
Just waiting on replacement second user Downpipes / Manifold - old ones were shot when I pulled them off - all studs out easy enough though - new studs and exhaust nuts purchased.
New Oils this morning ready to fill Engine... Gearbox Oil and Final Drive
New and Old Pics...

Save all receipts in case DMV asks you for the motor number, as they did to me when I first purchased my current K.
It's a 'reconstruction' thing. Happened to me twice, once a reconstruction and once on a simple title transfer. All the cars and bikes bought and sold over the years and never asked for engine number? I asked why, they just repeated, go write engine number here, drawing a blank on the title. I did it and they said I had the wrong engine? That one took five months to correct and never found out why? And the bike had the original engine? According to manufacture data anywho. Two centavos, FWIW.

The Ministry of Transportation inspection in the UK is probably much worse than anything Minnesota has thought up, although I'm sure officials in MN are frying their brains in an effort.

Actually they are pretty easy over here, they don't check Engine numbers at testing time... only Chassis number to check it's the right Bike they are Testing... I can change number on log book though, good shout. UAE is harder than the UK in this respect... everything has to match, including Colour of Tank.

Replacement Manifold arrived this morning, re-fitted Tank in readiness... should fit tonight and find some Fuel.. will report back or post another "Help" thread!!!
-
Success - exhaust manifold and silencer on, couple of cranks, bit of choke and it starts and runs...
I put 10cc of Oil in each pot to seal it and seemed to do the trick... very pleased that this Engine is good - circa 54k miles on it...
Will try and upload the final start up Video and a link soon.
Meanwhile final Pic of re-build from earlier today - took maybe 40 hours in total... just the brakes to sort and then roadtest..
-
That came together very nicely.

Thanks, and thanks for all your support on this forum. Very helpful to get advice from you...
Here's a couple of pics on my first ride out.
Connected brake lines last night and reverse bled with a Syringe, that worked well... runs a little ropey, not sure why but couple of pops... maybe needs timing sorting but overall revs well and goes OK. Won't tickover without a bit of throttle so any advice welcomed on what to tweak first to settle it down?
I know every nut, bolt and cranny now on this Bike and I'm glad I removed the ABS - looks cleaner too.
Note Gauges mounted on right hand side - work well - I'll make another post about this, but really easy for RT to Naked conversions like mine... even glow in the dark!
Enjoy!

Very nice. Wow is that license plate huge!
