You need a press, some centres and a lead mallet to true it up I use a 6 tonne press, it does the job ok but does struggle on more modern cranks

its hard to tell from that picture but the piston & bore look ok? take a picture with the piston all the way down

New concentric

If you just go round with a toque wrench your wheel will go out of round rather quickly Do as b40rt says

Nice too see a tidy workshop

the bearing face on the little end looks like its seen better days, maybe the crank mains are also worn? the oil also looks quite contaminated with gritty looking particles?

It needs to be quenched in cold water to anneal (the opposite of steel)

I caught a virus at a trial, it causes a large rash of 5’s. It’s nasty, I've had it for years and it doesn’t seem to be curable ?

Locking wire from an electrical connector?

if its below the piston rings you can drill a small hole at the top of the crack to stop if getting worse I've done this on a few cylinders and its lasted years. Not my preferred method, but it does seem to work.

you need a press to get the swing arm spindle out (or in) the are very tight!

Yes, cub & bantam swing arms are interchangeable Are you just after a swing arm?

I change mine every 6 months (if I remember) never had a problem with clutch drag

I use dexron II in my txt pro I'm sure there's issues with the clutch and synthetic oil on the Gasgas, the clutch pack swells

You could have a blank machined to suit

I could do with a pair, it would clearly state my riding ability

If it is your ignition try Bradford Ignitions. He did one for me, cost £125 and works well (not for a gasgas though)

Why would you want a fast trials bike?

They now have a forum as well

I see someone is selling them on ebay, has anyone seen one at a trial? It looks quite heavy with an electric start?

I use Silkolene comp 2 which is synthetic I did use Castrol power 1 which also worked well it's also worth noting that Castrol and some other manufactures state a maximum of 50:1

I use 40:1 on my air cooled bikes, never had a problem

Very True the only way to find out is to do a trial

I wouldn't have fitted them normally, I just presumed they were correct. It was only after I looked at the old ones I noticed the size difference ?

I recently changed the seals on txt pro but the od of the seals supplied are undersize. They seemed to fit ok The od should have been 52.2mm but the ones supplied are 52.0mm, they don’t seem to be leaking but I’ve not done a trial yet! Anyone else had this issue, I don’t fancy wasting the oil to change them
