Thanks to global warming they've been 400 warm miles . . .
Is that a greenhouse gas complaint I hear coming from the North Sea oil region, or jubilation? :giggles  Anyway, I hope you ride thousands of comfortable miles—be they steeped in appropriate soddeness or bathed in foreboding balminess—on that non-pareil example of semi-queered–out mobility.

This is my attempt at rectifying the damage caused to the RHS seam where the tank leaked. Fingers crossed it comes out alright.

Is this another way of saying that the coating of the tank's interior didn't work?

No, no. The coating on the tank worked perfectly.

The tank didn’t leak before it went for paint, didn’t leak once immediately filled afterwards, or four hours later. It wasn’t until the following day that I realised fuel had migrated through overnight and had removed the paint in the RHS step. That was what prompted the POR15 repair, which worked perfectly, I’m only now rectifying the paint damage.

I'm glad to hear that the product worked well. Tank leaks can strike any of us, regardless of political affiliation or handedness.

Thanks, Laitch. I wish I had just done it as a matter of course in the first place. Should I ever build another, this will form part of the process regardless of tank condition.

Lessons learned.

The touch-up came out alright;






Got a shock at how dirty the oil seems already. I’m 602 miles in now. Like any internal combustion engine I suspect this is normal?

That's what you get for changing the sight glass. The rest of us can blame fogged up glass for the dirty looking oil.  :hehehe. Anyway that looks reasonably clean to me. When its black its dirty.

The new turn signals arrived so I set to work:

OLD




NEW


The eagle eyed of you will have noticed my tail light is smashed :( Design flaw on my part. Strangely I hadn’t considered it being ravaged by stones off the back tyre... anyway, new one is on order and I’ve marked out a deflection plate in some 1mm steel which I’ll spray black and install with the new unit, should be unnoticeable. Luckily the actual LEDs are red and not just a red lense so I’m safe for the moment.

Really happy with the turn signals.

Thanks to you, Skunky!!

Unfortunately not, it won’t arrive until Tue/Wed. Not going to win any prizes for a smashed tail light but there’s always next time.

I didn’t ride her for three days and now she’s angry.

I went out to ride her to the gas station for a top-up ahead of the run to the event tomorrow. No start, no start, no start.
Pulled the tank 4 pin, cleaned, dried, no start. Pulled the FICU plug, cleaned, dried, no start. Tank off, 4 pin, no start, ICU clean, dry, no start.  :dunno2: Pulled the FICU plug again, cleaned, dried and she started on full choke but when given any throttle, died. This went on for about 5 minutes until she was a little warmer but then would not stay running unless the throttle was open even on full choke.
I let her die, threw on my helmet, jumped on started and rode off. Once the bike was up to temp I closed the choke. First set of lights she died but then restarted off choke and idled fine. This was a hit or miss for the next 10 junctions/lights, the ride between each set of lights was a mixture of no issue or a miss firing feeling as if running out of fuel, very spluttey, feeling starved.

Got fuel but then half a mile from home she died at the side of the road. I restarted her and no complaints, rode home, pulled up to the garage and she died.

What do you guys think? Fuel Pump, injectors, FPR, electrical. Potentially the pump is too far down in the holder as Laitch once experienced. FYI the filter is new and the bike was running perfectly when parked-up on Monday.
It’s worth noting also, I changed the fuel sender on Monday when I painted the tank seam... could this be a problematic 4 pin?

I have a video here, the bike is at temp and maintaining an idle now albeit erratic:

Reading this post back to myself I realised I was forgetting Law #3, trouble shooting: Look where you last worked. Went back in the garage, drained the tank, pulled the pump, disconnected the new old sender, removed the new old sender, reinstalled the old old sender, boxed everything back up, started, no complaints went for a 3 mile run, borderline perfect.

Why was there a new old sender in there anyway—treatment by part substitution via the shotgun approach? Don't run over any glass slippers.

So it probably was the 4 pin into the tank? Can't figure out why the fuel sender (fuel level sensor?) would cause poor idle?

This seems to be the year for dodgy fuel level senders.  I'm read about half a dozen or so different threads where internals on the senders suddenly go intermittent.  Every year it's something -- dodgy HES, dodgy ECUs, gummed up injectors.  It's inevitable.

Clusters of sprag problems, leaking tanks, etc.  The srevivce issue of the year.  How does that work???

Page 1, post #22, the original sender plug connection was fire damaged. I dressed it up with some heat shrink and electrical tape but that half assed approach was not the direction this build went in and I’d have been embarrassed to ever sell it in that state so purchased a new used one from my local motor works. I did notice the plug connection wasn’t great, the fire damaged one was nice and tight whereas the replacement one was more like throwing a hotdog down a rabbit hole.

So it probably was the 4 pin into the tank? Can't figure out why the fuel sender (fuel level sensor?) would cause poor idle?

Potentially the 4 pin connection itself yes or the internals degrading as RBM has mentioned, I’ll never know. Anyway, out with the old and in with the old... wait, what...

Inevitable concerns me. This is my only bike, think it’s time for another so I can walk away when the K is crying for something else.

We rode up to the Tomintoul Motorcycle gathering today, I decided not to enter the bike in the comp as the prize giving wasn’t until much later on and we weren’t overnighting due to commitments tomorrow, plus, there were some real heavy duty builds there.



I instead sampled the local delicacys, chased some Haggis and tossed the cabre.

Anyways, I was two up for the journey there and back. The bike wasn’t running fantastic, felt a little lumpy, throttle wasn’t greatly responsive, a little slow and spluttery. I have yet to sync the throttle bodies, I’ll do that this week, valve clearances are all fine also- what are the causes? Vac leak? I did install the plenum mounts with gasket sealer as well as the o rings and the rubbers where all fresh so don’t expect a leak around there.

At mile 112 she started to run out of fuel, luckily the road consisted of twisties to the next gas station, she died as I was rolling in at 115 Miles. So, 115 Miles to a tank with pillion averaging 50/55mph. Does that sound like good range carrying pillion?
