I think mine really needs a rewire, so much of the harness has been butchered, other parts are brittle, a lot of it is waterlogged. The principle I’m working to is track & trace fault finding in all the usual “barn find” areas, got it running, now running well, get it stopping, steering, bouncing, see where I’m going, tell others where I’m going, what’s that puddle, how fast will she go, ooh that’s rusty, but one day soon I’ll be able to jump on it, go for a blat on a B road, realise just how good it is, maybe use it for commuting, ride past that bikers caff where all the shiney weekend hogs park up (have to, its on my way to work...), relive the fizzy days of my yoof..
Sounds all poetic doesn’t it

Cheers! It’s not actually been that full on today, just 10/20 minutes on and off, hardest part was getting the bottom bearing off the tree, luckily I’d bought a blowtorch as I’ve got snapped studs yet to do.
These are the relays, not as small as I’d hoped but at about a third of the size of normal ones I can fit a few in the headlight bowl!

I’ll fit small blue crimps - remove the insulation then heat shrink over the crimps to hold them in place. I’ve removed loads of twisted wires and a few blue/red crimps and there won’t be any going back on!

Good day today:
Relocated ignition switch to under tank.
Tidied up wiring loom under tank, added a fused heavy positive lead up to the headlight and fitting micro relays for horn, headlight (H4 conversion), and coils. Added an extra earth lead bonded to the frame. Wired horn to/from headlight, same for coil live side. Don’t think my kill switch is the best hence fitting relay, maximise voltage to new coils, caps and plugs. Already sorted static timing and last time out the bike was pulling nicely so should be even better.
Test fitted tank, no wires fouling.
Renewed head races, refitted forks, wheel, waiting on new pads. Rebuilt the caliper yesterday.
Renewed all brake hydraulics down from the master.

Tomorrow refit clocks, fit caliper if pads arrive, start building new sub loom in headlight for the above. Renew throttle cables and route properly. Refit rear mudguard and rewire rear indicators. Replace master fuse holder...

I’ve made up a bracket from some old VW seat mounts, see how I get on with it. Didn’t even know it was supposed to be down there, I thought that was K0s only. Shows what I know! The “originality” rebuild went out the window early on when I realised what a mongrel I’ve got.....

Could anyone show me how it’s mounted? I’m stripped down far enough to do it now. The flapping fob annoys me in the bars and it’s taking the paint off the idiot lights! My Triumph does the same but no messing with that one....

Yep, just spent the last hour doing exactly that obviously ditching the speaker wires for the correct colours. Did the K2 have it on the bars or the frame? Got me thinking now!

Consensus wins
Having a look at the ignition switch harness, I think you’d call it hotwired.... Surprised it even ran like this!

Having slept on it, the main reason to strip the caliper was a dragging brake - on inspection this was clearly caused by the pad not the piston, the pad was rusted around the edge and possibly even a few thou too big. The piston was pristine, the cylinder also. It wasn’t leaking before so I think I’ll be best just reassembling rather than risk a bodged seal...

Spent the day working through electrical stuff as I’m held up waiting for head races. Stripped back the front outer loom to find it very wet, a lot of old tape etc. Worst bit was when I took the ignition switch off and found the whole sub loom was wet, taped to death and twisted connections on both ends! Glad I bought a new soldering iron..
The new coils fitted best with the HT leads pointing forwards, is it best to run the leads back over the rocker box and p clip them there? Can they be cut? I’ve also found a light green wired female bullet, looks OEM, under the coils, and I don’t know what it’s for!
I’ve also laid a fused heavy wire from the solenoid to the headlight bowl, and ordered some micro relays so I can beef up the lights & horn.
New pads ordered as the half worn ones were sticking in the caliper and a bit chewed up. Piston good just new seal and rattle can job to do. New hoses and line to go on as old one was rock hard.
Got to replace the throttle cables, stripped down and found lithium grease on the grip end, is it ok to regrease when refitting?
Tacho cable screw stripped in the head so that’ll have to stay there for now.
Still enjoying it, I’m getting more disciplined with hobbying it rather than working against the clock :-)

Stripped the headstock....
Made a ball catcher rig


These vinyl wrap magnets have been invaluable on loads of projects, expensive for what they are but bloody useful



Only problem was 17 balls top, 17 bottom so a bit short. The races are chewed so I can’t re use anything. More bodgery betrayed by the loose lock ring, although there was no slop, only grumbling.

I can also recommend this liquid for degreasing, far better than its intended use, at 20% alcohol it kinda interferes with the D&A policy at work, and it stings!

« on: June 26, 2020, 11:23:03 PM »
well, judging by my recent experience, I wouldn't worry too much, the 750 tanks seems to look pretty good and fits well.  I might weld my old tank sometime but I'm in no hurry.
I’m right up there with you, my 750 tank fits fine, I’d rather enjoy my bike as is, assured in knowing I do actually have the right bits if I need to sell it, which isn’t likely. It’s far better to be smoking round on a bitsa than stay at home polishing my pension!  I’d really like to get mine to a level where it makes my daily Triumph Triple redundant. Now that I’d be happy to polish....

Massive shopping list this week, spent all my PayPal balance! Stripped the front down and found the legs are bent back about 1.5mm, stanchions rusty, headstock rumbling. I have to shout out to Dan at Legend Motorcycles on eBay for great comms, help and next day delivery.
New OEM coils, plug caps, brake lines, headstock bearings, fork seals, gaiters, throttle cables, caliper seals, sourced a used factory manual (brilliant), getting the rolling chassis sorted at the moment. K1 tank off for proper repair, 750 tank back on for now. General wipe down and degrease whilst it’s on the lift, lubed tacho/speedo cables etc etc

Sorted, got these of eBay and they fit perfectly.

I thought so but they have the same thread as the front ones, if I can source the nuts I can put them on without some bodged brackets. Bike is off the road on the lift, this is the last job to do on the rear end, then I can spin it round and do the forks, caliper seals, brake hoses/line, throttle cables, headlamp wiring, and just get out and ride it!
It’ll have to remain a bitsa for now, but I love riding it as is
