Hooli's 14 Mk2...

[grog]

A tough one, those stainless bolts require lubing absolutely, tightening??Sometimes I think hand feel is better on small bolts.When doing auto transmissions etc,I always used 1/4 torque wrench.Not much help am I😂

[Eric GSX1400K3]

Agree re hand feel on smaller bolts. My rule of thumb is that if lubed, apply 2/3 specced torque, unless you find info that specifies bolt torque AND thread condition

[Hooli]

I only ever do them by hand on such things, nip them up & then just a tweak.

I think they are just crap quality bolts, they feel cheap & nasty when you handle them.

As it's actually been nice enough to do stuff outside today I've made some more progress.

Advancer mod done, the magnet on this was broken in half but went back ok. Hopefully it won't affect the running as it's held in place with two screws so can't move once clamped up.





Then by evicting Snotbox into the garden I could move my proper 14 & get up the LH side of Mk2. The clutch slave cylinder appears to have never been off, it took ages to crack it free from corrosion on the mounting sleeves. Utterly disgusting inside too & the cylinder has seen better days. It's smooth now though so should work. If not I think I've got one somewhere as I bought one ages ago & don't remember using it. The front sprocket is genuine with the noise reducer too, more evidence this side has never been touched. It'll need chain & sprockets in a year or so looking at the front teeth, but that can wait till it's needed.





I didn't bother bleeding the clutch up as I'll be disturbing the master cylinder when I get the bars I want for it. The covers aren't back on the other side either as waiting on those new bolts, I'll change the wanky-snappy ones in the stator cover at the same time too.

Off the top of my head the list left to do is a lot smaller now -

Fork oil
Check & grease steering bearings
Paint strip the clocks & headlight to get the chrome back
Sand the engine fins down to get the upper silver ones back
Maybe paint stripper the throttle bodies cause they've been painted black too
Vacuum hoses just because & then balance the throttles as I bet it's never been done & the idle sounded a little rough when I collected the heap
Rebuild the front brakes as I don't trust anything the PO had touched
Refit the chain guard & oil cooler cover. I was going to get different ones, but these can go on for now as I'm not fixing every bit that got painted black for no reason so they'll look ok
Fit different bars

That should cover it I think. The bars are the only thing that might hold it up as I've not ordered them yet. The plan is to buy a mate new bars & have hers as I like them, but she's not sure of the ones she wants as the person who's got them on her 14 hasn't checked yet. Oh yeah & I need to find my original grips, I know roughly which box they are in but can't get to it without moving the bike lift.

Re stator and broken magnet, mine had the same.  I superglued the halves together and it worked fine.  I did end up finding an aftermarket stator plate and fitting that, when I was chasing the stutter and misfire late last year (ended up being the crap injectors i found on ebay, original ones back in and all is well.)

I'm not convinced that with only the two screws holdingvthe broken magnet in that the Hall Effect sensor gets a clean pulse for crank position.  Gluing the magnet def helps, but a new magnet would remove all doubt.

Here's the one I found that fits my K3  perfectly:

Cheers Eric, I didn't know you could get them aftermarket. I had the same thoughts about a clean pulse so will look for one of those more locally.

[Hooli]

Well there's nothing locally, but they are 'only' £95 from Webike Japan rather than £370 here. So if it does have running issues I'll get one, I'll probably need to order the top bar clamps & stuff for my proper 14 as unlikely to find them second hand. Not that I've looked yet though.

[Hooli]

Small updates...

My bolts arrived & I've found out the bars I need to order so they'll be here this week. I've even ordered bar end mirrors as the standard ones will look awful on it, I think I'll hate them as I always do when riding with them. But I can ignore them & turn my head.

Can I ask how does the magnet get broken ? 😳

Vibration and heat I think Chris. 

I think the stator plate gets hot and warps just enough to stress the magnet, and as the magnet is so brittle, it can't flex with the plate so it breaks. Engine and bike  vibrations wouldn't help either.

The sensor sits over the top of the magnet, inside its magnetic field (it's a permanent magnet), and gets 5V from the electrical system. The rotor fixed to the crank sweeps past the sensor leg with only 1-2mm clearance, at whatever rpm the crank is doing, this disturbs the magnetic field around the sensor and this changes the voltage that the sensor sees.  This is how the ecu knows when the crank is at TDC and sets the spark and fuelling timing accordingly.

Magnet and sensor are held in pretty securely with two screws. The magnet is like a little bowtie, with holes in the outer 'bow' bits, and skinny in the middle where the sensor sits and rotor sweeps past.

Mine was broken exactly in the middle, when glued you couldn't even see the join.

I suspect that when its broken, the magnetic field is not as strong or whole, so the field disturbance is not as good, and the crank signal sent to the ecu gets fuzzy, this would lead to incorrect fuelling and ignition timing, resulting in rough running.

AI & Google agree completely with Eric on the magnet,   AI answer to the broken magnet question:

In a nutshell it's a disturbance in the force you seek.

That's a very comprehensive explanation Eric thank you 🙏

Aren't I glad that my University degree in Mechanical Engineering is now at least compatible with some useless bit of ai software that just trawls the Internet looking for comparable keywords.

No disrespect Col, I don't take myself too seriously at the best of times, life's too short.

[grog]

Great answer, never knew any of the magnet stuff, Col from the net👍Eric from the first hand. Good on both of yas👏👍

More frustratingly slow progress today due to the skills of the previous owner, but I'm getting there.... I'm off work for two weeks & expect this thing on the road before I go back so I tried to crack on today.

Clutch & ignitions covers fitted with new gaskets & new stainless bolts that aren't made of cheese. Stator cover bolts replaced as well, but two left loose as the sealing washers were missing & I don't have any to hand. I've ordered a pack & they'll be here in a day or two.
I wasn't happy with the clutch slave cylinder after putting it back the other day. I was sitting there later that evening & decided it wasn't right & I was looking again. Well I was right, I hadn't cleaned the bore properly. I have now & it feels right to push in & let the spring push it right back to the top of the bore again, it was sticking halfway when I took it off earlier.
At this point I popped into town on Snotbox with a handful of bolts I needed to get longer versions of. So it chose that point to rain as I rode back, good job it's not far.
Engine bars fitted, which was a nightmare as the threads on the frame where the triangular engine mounts fit were all damaged as the previous idiot hadn't used longer bolts with the comedy climbing frame (renthal?) bars he'd fitted so they were only in a few turns. It's sorted now though & new longer bolts used on the rear of the plates where the new bars fit to ensure they're into good threads.
I've put the oil it came with back in as it looked clean enough & I'll ride it for 1,500mile or so to get to 48k & then change it by mileage in future, well I put most of it back in as it was overfilled so I've got about 300ml of that oil left so it's correctly on the full mark. I also adjusted the chain & set the back wheel straight as I'd not done it when I put the back end back together the other week.
I've replaced the crappy bolts he'd used on the grabrail with the proper ones & discovered he'd stripped the threads on both sides for the smaller front bolts. Thankfully there's just enough room on the end of the bolt to add a nut to save needing to get that sorted out. I'll just have to remember to catch them when the tail comes off to clean the thing properly, I'm sure it's filthier in places than my old 14, just not as rotten.
The longer bolts I'd got for the exhaust clamps went on so the cans are now supported, the ones it came with were too short to put the nut on once I'd replaced the missing washers around the rubber bungs in the peg hangers. The last job was cutting down the bolts that held the ugly mirrors on & pop them back in to fill the holes in the lever clamps.
Finally I swapped things around in the garage. My old 14 is now on the ramp & pushed right into the corner, Mk2 is pointing out & stood on the floor again. So it's ready to strip the front end down & see what horrors I find there. I might carry on tomorrow, but think I'm busy for most of the day doing other stuff. I'll get there though.



Have a pic of how it looks now.
