If you've not had the pleasure of bleeding a GasGas rear brake before, I predict this might be your next question!🤣 It really is a huge pile of fun!

You say you had a leak, so as the fluid level dropped it has sucked the rubber boot down into the master cylinder. Don't worry that's how it's meant to work. Just collapse it back into shape then put it back in the top of the reservoir and then put the cap back on.

There are other mistakes, it seems like they just cut and pasted info from the TXT manual to Pro manual. Fuel mix says 2% (50:1) the TXT crank bearings were lubricated by the fuel mix but Pro crank bearings are lubricated by the gear oil so you don't need as much in the fuel. Many people on here run between 65:1 or 75:1.

Yes you're right, about 1ml of soap in 1ltr of water.

I've fitted a couple of non genuine sets. The piece that goes on top of the airbox can be the trickiest part of the job and you need some masking tape to hold it in place until the soapy water has dispersed and properly dry (24 hours).

See how you get on with it! Try somebody else's to see what you may prefer, my opinion would be a 250cc. So there's a bit of personal choice what you feel comfortable on and what you enjoy riding. That's what it's all about!

I think you could change it if you wanted to. It looks like you have glued the drier to the outside of the 4-way, you could cut the 4-way just in front of the nozzle of the drier and re-attach with an inch long piece pipe on the inside of the 4-way. so it would be invisible.

I'm not sure if they are still available but there used to be cylinder head spacers. flywheel weights are good at slowing the acceleration and great on muddy off cambers but also slows the decreasing revs (i.e. keeps going). I softened the rear shock so the back would dip and take up a little bit of the power before take off, so add that to your list of things that cost nowt. Broken ribs I know what they feel like, I felt like I couldn't even blink without squealing! and collar bone I used to hear it grind when trying get to sleep😮. Hope you recover soon.

Gas Gas clutches do drag a bit.

The Exhaust looks like the earlier type where the silencer would be bolted onto the mid section. Previous owner has welded over the bolt holes and welded the two sections together. Making it more robust. You definitely have a Pro motor and it has a 280cc barrel on it. The fuel tanks on the 07's were black so you may have an earlier one. I am still puzzled why the frame is black underneath the VIN sticker, that says the bike was built in 2003 Feb. Maybe a newer frame with the old sticker transferred on to it. See if the numbers match up! I wouldn't worry about anything as it looks fine, If you're new to trials then I hope you enjoy it and don't throw it at too many rocks!🤣 I've got a 04 model but the VIN has an "E" in it which was the first letter they started using.

There should be a letter in the middle of the VIN, 2004 E, 2005 F, 2006 G, 2007 H.

Yes you're right, The Raga replica models were a year infront of the standard models but there are fewer of them!

It was late 2005 when they changed the clutch from brake fluid to mineral oil. I use Dexron III ATF in the gearbox.

If you wash your chain then WD40 may help to dry it, ('W'ater 'D'ispersant 40th attempt) It is a water repellent/dispersant but Not a lubricant so bad news for a chain! For trials a heavy gear oil will be ok, or old gearbox oil. Just pour/brush it on.

it makes it almost a pleasure cleaning filters🤣
