I dented mine, but nothing as bad as yours Lian. Using the method Spark describes I was surprised how easily a friend was able to blow it back out. Its not perfect because the metal had stretched in places (titanium is pretty soft) but it was much better than having to buy a new one.
Thanks Jon. I have to agree that GasGas clutches are pretty good these days and I haven't had any problems since the first model Pro came out. After all, it's only for changing gear Dave
The oil you use won't make any difference to the amount of effort required to disengage the clutch. A lighter diaphragm spring was fitted from 2006 and you could go that route, but first off I'd check that the 'pack height' of the clutch discs is within tolerance because if this is wrong it can make the pull heavy. Jon Stoodley is your man on this. Search these forums and/or take a look at www.gasgas.com
The cross head screw at the bottom of the damper alters the damping and affects both compression and rebound at the same time. The threaded collars (which lock together) can be moved up or down the body to adjust the amount of pre-load on the spring. The screw inside the hexagon locknut at the top of the shock should not be touched as this is where it is charged with gas. Cheers, Dave
The FIM have no technical representatives. They have guys who go out and homologate venues, but very often those guys are not qualified to decide and venues should not have been homologated for various reasons.
The overriding consideration seeming to be good parking for the factory trucks rather than natural terrain for world class sections!
Thanks Nigel. I'm no supporter of the new rules and have only seen the video where it appears that even some of the observers find it too boring to watch! I don't know what the FIM are trying to achieve. Did they consult the riders and manufacturers? Is the aim of the new rules to make it easier to televise these events, or what?
I await Nigel Dabster's first hand account of the trial and verdict on the new rules with great interest. A superficial scan of the results suggests to me that if it was the FIM's goal to narrow the gap between the best and the rest then this has not been an immediate success. If Michael Brown 5'd every section(?) I rest my case!
Maybe you're right Nigel, and the organisers do know what they're doing otherwise I'd worry that the sections could be like the Boulder Dash at The Tough One. I just don't like the time element being tightened up so much that the effect will be that we've come almost full circle back to no stop trials without the rules actually saying the rider can't stop. I'm not advocating no stop trials, but would prefer that to having a time limit that is likely to play into the hands of the top few.
Thanks Andy, I was thinking of making the 1,000 mile round trip to watch the British round at the end of June, but I don't think I'll bother now as I don't think this new version of top level trials has any relevance to what I do at weekends. However, you're much more likely to see me at the 6 Days.
Mine was leaking and I bought a new seal kit, but when I stripped it down and cleaned everything I couldn't find anything wrong. Don't know if a bit of grit was lodged under the lip of the seal, but I put the original seals back in and its been fine. Just a thought before you go spending lots of cash.
Can't help you with the larger master cylinder as I have no experience, but can't see any benefit in making the retrograde step back to using brake fluid.
On the end of the gear lever shaft there are two spring loaded rollers that engage with the selector drum and rotate it in either direction. You've broken the little spring on one of these so the drum will only turn one way - into first gear and no further. I have a nasty feeling it could be a motor out, cases split job but perhaps its possible to withdraw the gear lever shaft from inside the clutch case? No doubt someone will come along later who knows for sure.
Get the bike hot and pull the waterpump out from the clutch case so you can see where the water is coming from? Maybe you've got a pin hole or a porous casting?
When you did the main bearings did you take the head off the barrel? I know there's no need to, but I wondered about the condition of the rubber 'O' rings. If they're on their way out the cooling system can be pressurised by leaking compression and make the pump leak. The bike will usually spit coolant from the overflow too, if run long or hard enough.
Sorry to hear about your difficulties. Are you actually losing coolant? I've found that my gearbox oil will go milky sometimes but the coolant level is okay and I wonder if its just down to condensation or water getting in via the breather. Once the oil has gone milky its difficult to get all of it out and it can take several changes to get it clean again.
