[St300 running too hot]

Newer ST's don't have pipe drain hole like first models. 

Oil can acumulate inside pipe if you ride for long periods slow. If after that, you ride it hard (uphill open trothle for long periods) it can ignite "gum oil" inside pipe and get very hot with a lot smoke. I think this hapened with me when bike melted rear fender.

Maybe backfire sheared the key.

Replace your spark plug and check connections, engine stop button, etc

[Sherco ST 125cc to 250cc]

125 has same stroke than 250cc?

If yes, you can study parts numbers and see what change.

i take it if you can't get michelin x lights or X11 and dunlop D803, you've tried Prielli MT43, IRC, and even Mitas ?

No. Only Michelin.

But have friends who tried pirelli (crap) and mitas (better).

Will give trialmaxx a try. 

[Maxxis Trialmaxx]

The idea is use them on my ST300. There is no michelin or dunlop here now.

Can mount them without a tube?

They are bigger?

Any traction loss?

Thanks

Spoonge can be related to Carb setting too....or ridding too slow

29 minutes ago, old trials fanatic said:

FWIW i was told by the Motul rep ages ago that full synthetic in a trials bike doesnt burn away in the silencer because the motor doesnt get hot enough like a moto crosser or race bike so they recommended semi synthetic. Actually they recommended their "scooter oil". I've used semi synthetic ever since with no problem but i am sure many will disagree. Always a horny subject this with so many different "recommendations". As long as the user is happy then thats as good a result as you can hope for. 

Look at "flash point" at oil specs and choose lower ones to avoid oil spoonge at pipe

Motul 510 is going OK for me. Maybe will test the 710 someday.

[Rear Wheel Bearing Removal Problems]

Jitsie sell this tools.

Yes, it is overkill for who change bearings of one bike 4-5 times in a decade. But your mechanic has to have one...if not, run away.

[Rear Wheel Bearing Removal Problems]

My answer is a expanding mandrel.

Fit the mandrel in bearing

Put the expanding rod from other side

Hit it with a hammer

The bearing will exit centered. This is important to not enlarge hub hole

To fit new one, you will need a tool to keep spacer centered and apply force centered only on external ring

[Gasgas trials 250 fan issues]

Fan should spin if you short circuit thermostat wires.

If not, check AC before and DC after rectifier/regulator (small square black box)

[Oil Level 2004 Sherco]

Theres no fill level. 

When you change oil (around 450cc) it should keep at same level if there no leaks.

Cooling system takes around 500cc.

what pressure works?

90 psi and turn the part you want to fix red hot with a torch.....use a pressure regulator to maintain pressure constant since it tend to increase when you heat the carbon inside (burn most you can before), use thick gloves, face shield and all proctetive equipment you have since it is something dangerous.

[Machining Your Own Parts]

Fixed some dents on pipe using air pressure and heat
