[Two stroke Crankcase sealer]

I use a good quality clear instant gasket and the proper paper gaskets. never had a problem with oil or fuel leaks  

[Splitting Villiers Crank]

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

[Mont needs a doctor]

its hard to tell from that picture but the piston & bore look ok?

take a picture with the piston all the way down

If you want to stick with Amal then a 622 concentric is the one I have always used and is the one specified/supplied by Amal for a C15

I have a spare perfectly good used one but I’m guessing you’re in Australia. I’ve seen trials type pattern on 20 inch C15 wheel maybe ok for green lanes but not a trials competition tyre, 

New concentric 

[Spoke Torque Settings Montesa Front Wheel]

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

Do as  b40rt says 

[Midlands Newbie]

Nice too see a tidy workshop 

[Engine oil on left and right flywheels - 247]

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?

Use a blowlamp to heat it up to cherry red.  Allow it to cool down naturally.  

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

[Coronavirus and trials?]

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 ?

[HELP NEEDED]

Locking wire from an electrical connector?

[Cylinder repair]

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.  

[Tiger Cub Swing Arm]

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

[Tiger Cub Swing Arm]

Yes, cub & bantam swing arms are interchangeable  

Are you just after a swing arm?

I now think it was something to do with the clutch dragging if you changed it more regular it helped

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

[Dexron2 or dexron2 mineral]

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

[Rear sprocket/brake drum]

You could have a blank machined to suit

[Front Cover of TMX - Made me laugh anyway...]

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

[rsvrt9]

If it is your ignition try Bradford Ignitions. 

He did one for me, cost £125 and works well (not for a gasgas though) 

[Bultaco model 92 big bore ? How big can you go]

Why would you want a fast trials bike? 

[Tenaci-wong]

They now have a forum as well 

[Tenaci-wong]

I see someone is selling them on ebay, has anyone seen one at a trial?

It looks quite heavy with an electric start?

Semi or fully syn 

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 

[Pre mix]

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

0.2mm = 0.008"  dont worry about it !

Very True

the only way to find out is to do a trial 

[Undersize fork seals]

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 ?
