Honda-SOHC

It's a non-runner at present. It's all there so far as I'm aware but has a couple of broken studs ...I'm not sure if there are other issues as I haven't had it running. Head is currently off plus there is a spare head and possibly barrels. It's been sitting part dismantled in the garage for ages. I can take a few piccies if you like.

It's East Yorkshire for me (but currently in exile in the South)!

I used a method an old American bloke uses on his XS650 on YouTube, same principal but using a large nut and bolt wound out inside the piston, stick an open ended spanner over the bolt then a bar through the ring end to twist while pulling up gradually.  Photos might help with this description 😀

I think I can picture that - I'll try on the rear stuck piston/ caliper...I think that only has one piston!  The great thing is, once something works I start to feel a bit more confident. These brakes had been really getting me down.

I've been struggling with extracting 6-pot pistons from my ZX6-r (which has sat through lockdown and beyond and slowly seized up,) and I've been slowly trying to fix. They were stuck solid..all 12 of the little blighters.

I've seen various other tips but haven't found them easy in my garage and with limited tools;
- grease...I've only got a tiny grease pump and it didn't seem to get any pressure going. Plus it's putting lots of muck in the caliper.
- compressed air ...attaching a line always seems tricky. I've used this before on a garage forecourt but never felt it seemed very safe. Plus, with these caliper body shapes it's been quite hard to hold or fix anything to ensure one didn't pop out too far and still leave the rest.

So I found this clip online (and from Yorkshire!) and it certainly works. I split my calipers first so I could get to three pistons at a time. Jam the inside of the piston with screwdriver bits ( or small sockets) and a large allen key which you'll use to turn it. Once you start turning and it all jams up the piston will start turning. Then twist it upwards and it will slowly wind out. Amazing! And no mess.

I tried it a few weeks ago and managed to get them all turning but they were still not keen to come out.So I sprayed a lot of wd40 around the pistons and forgot about them until today. Today they just twisted out relatively easily. Genius!

I'll dig out a piccie of my LC. It had the Pro-Am fairing and bellypan but non-standard paint, so had probably already been crashed when I bought it. Unsurprisingly , someone (!) crashed it again.. I fixed it all up but sold it on in about 2000 for just 400 quid to someone in Harlow. it's still showing as MOTd- I would love to see it now, probably fully restored and immaculate. I still have the original number plate and a very bent/ crashed rear brake pedal! TJA242X - if anyone sees it!

That looks like a racing oil catch thing. In the old days (!) the MPS and M&P paper catalogues used to have universal bellypans .. they were smaller than those though.

Or try and find an old fairing and cut the bottom down to size? There are CB500 (the modern twin) race ones on eBay but they may be too narrow.

I still have a vision of a silver GS850 hardtail in AWOL magazine, with a small bellypan and sharks teeth painted on t...fabulous style!

Looks awesome..and warm too! It's only -4 down here (and far less Oop North)!
