Nup...id say the donk is in 2 pieces on a bench atm  Top getting a going over as well

(gulp) if anyone knows where some good condition barrels are ..let me know

Absolutely crazy it was still running just so well. Anyway gudgeon clip missing so gudgeon has scored the right barrel very deeply & the mech isn't confident with a bore. Left rod is damaged also blah blah blah ..soooo all good full rebuild & I get a good bike back I can look after. Any UK recond barrels about ? I cant see any online going through the 5-6 main BSA shops online. We are both going to have a look about. He said the seat is really good though

If your barrels are otherwise good then price up sleeving to std and std pistons.  Its a good repair and may not be a pricey as you expect (fingers crossed).
Gudeon pin circlips should not come out (they are hard enough to get out when you want to) so the question has to be asked, were old ones re-fitted?

Just a note on this.  When Bergs rebuilt my engine, he found that the guy who rebuilt it before (who was supposed to be a classic bike builder - not), had used flat circlips that were not located in the correct slot but between the gudgeon pin and the piston.   It had been this way for 10,000m of reasonably hard riding.

For the full horror story of my engine rebuild, see: https://www.a7a10.net/forum/index.php?topic=17648.0

I've just got a new set of gudgeon pin circlips to replace while the engine is apart.  These are the plain wire type and interestingly the ones fitted are wire with a loop to make them easier to get out.  The new ones are very stiff and take noticeably more compressing to get them to fit.

There is a barrel on eBay at the moment. At 250 quid this seems an awful lot of money not to mention getting it to you.

It is close to me for a change.

Great mate tar, onto it now. Ive bought a few bits & bobs from them & their post is super fast. I did look there but rushed through looking for full barrels

Cheers mate, i let the bloke know. Hate mentioning things like this to mechs but ive been 42 years in my trade & ive learnt sometimes a simple bit of advice goes a long way. The older i get the more i think my father was right

Another benefit of sleeving back to std is that I think you may have more choice of pistons.  I think some of the oversizes are in short supply.  I see the Indian's are doing 8.5:1 with rings for £90 posted for a pair.

Good point. I kinda thought if I get a yr out of it before a build that’d be ok but it’s now a bit earlier. I like my bikes reliable & running well so a fresh engine & lots of new oil & no one but myself on it I recon it will see me out

STD pistons (NOS) are often cheaper and more common than oversizes too for obvious reasons.
