I doubt you are going to give up that easily :D

Never mate.. I told him to get some bits done then bring over here, but i can see where he's going as some of the jobs would need doing twice if he does them now, then uses it, then does them after.

My argument was "What's the point in having a bike ready in November, may as well get it mechanically right for now, use it at end of summer, then address the other bits later on"

He didn't go with it. :thumbdown: :wtf:

I think the last fill up was in Belgium or France and will have been 'Super' so I think that was why they were 'clean'.

Amazingly the float bowls were still full, so I think that as the fuel in them evaporated they refilled so as they didn't dry out there was no gunge.

I drained the fuel and it came out looking like 'bitter'.

But, yes. Very lucky - I envisaged gunge and sending off to be an ultra sonic fest.

You got me worried there.

One cheapy - £9.99 endoscope from Eurocarparts later (the software with it doesn't work but generic USB camera software solved that) and a nightmare when the camera got wedged behind the fuel sender :wtf: we have a mostly clean tank with a little surface rust in places.

This is the worst of it:

I'll get some DEOX and give it a good swill round. Monsters use a Fiat fuel filter so any that gets washed off should get caught.

Might not be too bad, but if funds allow I'd still seal it...

My SSie tank leaked at the rear seam, the POR-15 fixed it really well, makes the inside of the tank look all nice too.

{{{{shudder}}}}}

Hmmm, never liked that stuff and it's a bugger to get out, did a tank which rusted through and ended up cutting the tank in half to get it all out and getting new bits welded in.

I've silver soldered the rear of my tank where they split at the spot weld so it doesn't leak. In reality I don't think I actually need to do anything the rust is only surface rust, the petrol sloshing will stop its spread but I'll do the GEOX and see.

Citric works well. I use it diluted 30:1 weight for weight with water. Wilco sell it mail order.

I've never tried it but plan to on the KH I'm very slowly rebuilding :oops:
It does work well, specially with hot water. Where is the KH thread then?

Too late, just pressed the buttonon these two:

https://www.bilthamber.com/car-cleaning ... /surfex-hd

https://www.bilthamber.com/corrosion-pr ... nts/deox-c

The pair cam highly recommended for cleaning out fuel tank, degrease then a fill with the Deox solution.

Will do some before and afters to see if they're worth it.

As it had been standing the belts will have 'set' so ordered new ones which arrived today with some moving tensioner bearings.

So off with the belt covers, however while I was taking them off I noticed oil over the back of the motor, damn! The rear cylinder base gasket has been weeping.

Undid the rear cylinder exhaust nuts to sse if they would move, wow, one good soaking in penetrating oil and off they come. Removed the breather tube for better access to the nuts.

My 620 motor had the same leak. I took it to bits, put a new gasket in and a bit of sealant... it still leaked. Lots of them do. Ended up with a sponge wedged under the bottom cooling fin to stop any oil from pooling and flinging. This was a rough and ready race bike so it didn't really matter about the cosmetics.

Gaskets and a couple of other bits to be ordered from Germany. So while I wait for them I decided to start at the front on the cleaning and checking.

Front wheel came up OK, going to need repainting though, that can wait until winter. So onto the disks, some before and afters.

Mine never used to so it maybe curable, or maybe I've never noticed it before. :)

There's not much there and I'm still mulling over just cleaning it off and waiting until I do a proper engine out frame paint job. I let Docca have a ride while I followed on his Buell and it was smoking a bit so the engine could do with a top end refresh. There's also a pair of 944 pistons and spare barrels sitting on the shelf. :D
