guys

Montesa's of course and the blue and white bikes are Yamaha's

Found another one that I'm going to try: GRO Gear Extreme 75W (comes very close to the recommended Elf oil)

It should fit because it's the same caliper that's on the 315R made after 2001. Don't know if the master cylinder also changed after 2001...

Do the pistons slide easely in the caliper? Are they not stuck from dirt build-up? Another option is a master cylinder with a smaller diameter plunjer. (if that exists) Also, but not cheap: http://www.splatshop.co.uk/xblok-billet-racing-caliper.html Back to galfer pads maybe...

Does the backflip count as a 5 in the new no-stop rule?

No thanks :-) As far as I know there are no additives in Alkylate fuel. so your valve and valve-seats have to be able to take unleaded fuel. And I think the same about the cost of Aspen fuel + the guy behind me waiting at a nonstop can breathe a bit better ;-)

I use the Aspen 4: http://www.aspenfuel.co.uk/products/environmental-fuels/aspen-alkylate-petrol/aspen-4-alkylate-petrol/ Which is 95 RON. I've also tried Aspen R (Racing fuel) (102 RON), but I did not notice any improvement to the Aspen 4. I'm a low level (randonneur) rider so I don't use the full power of my Cota 4RT. A Beta rider who rides in a higher class than me, says he can feel the benefits from the high octane fuel. There's also Aspen + 98 RON, but I've got no experience with that. Aspen also sells pre-mixed 2-stroke fuel: Aspen 2 (95RON)

That's some nice soil you've got there .

To much ethanol in fuel, can be a problem because it absorbes water. And we don't want to much water in our (metal) gastank, carburettor or injection system. About the other chemical crap in fuel: This is the reason why I use Alkylate fuel in my trial bike. It's better for man and machine. It not cheap, that's why I don't use it in my other motorcycle. http://www.aspenfuel...lkylate-petrol/

Just what we need, another crazy dude Welcome

Welkom. I've been on a motorcycle-holiday in Greece in the 80's... Perfect for trials, lots of rocks and mountains there

In Belgium it's the same , maybe even worse.

Altough i'm from Belgium my French leaves much to be desired. So I asked the organisers from the 4-day trial for info in english and they responded in English. Worth a try isn't it? ;-)

Works of art, those bikes! Very nice.

Here's another one (Motul):

If you've still got the original clutch lever, compaire the stroke the plunjer makes when you pull the lever, and the diameter of the plunjer.

Maybe it doesn't displace enough fluid to make the clutch work properly. I would sort this out, before dismanteling the clutch. This is normal.

So, apart from the price and availability (which is not a real problem for me), I don't see any major advantages ATF has over the Elf HTX740 oil. Or is there no drag at all with ATF oil? I have alway used the Elf oil in my 315R and also in my current 4RT and the only (small) problem I have is getting it in neutral. This is what the Italian Future Trial Racing team uses: Does anyone have any experiance with this gearbox oil?

AHA! So you're the one that's been nicking all the stuff!

+1 If Scorpa recommends fully sythetic motorcycle oil for wet clutches, I would stick to that, also make sure it's the right viscosity.

http://www.ajpamerica.com/master-cylinders.html Here's a list of the different AJP clutch (and brake) master cilinders. It's comes from the Gas Gas importer Trials Parts USA, but Montesa (and most other trial brands) uses the same clutch and brake levers. When I had my 1998 315R, I also had clutch problems and ended up, after a rebuild, replacing the complete master cilinder and rebuilding (seals and piston) the slave cilinder.

I think most riders already use this positioning of the levers. I do anyway for at least the last 10 years. On my mountainbike also.

Tubes in a tubeless tyre without a tyre clamp don't last very long is my experiance. Here's how I fixed my rear tyre. It's still air tight. http://www.trialscentral.com/forums/topic/43968-cuts-in-rear-michelin-x-light-tyre-sealed-with-stans-notubes-tire-sealant/
