If you mean linkage bearings it's not difficult but a bit expensive. A kit from 'All Balls racing' is about £60 includes Bearings, Bushes, Shims and Seals.

Plastic nut & bolts used for number plates work very well, some cable ties are tougher than the mudguard and can split the mudguard.

Great Pic's

I have cut and pasted this from the Gas Gas pro technical bulletin; Transmission oil: Recommend type: ATF DEXRON II Alternatives: NOTE: We have a few customers using the type "F" automatic transmission oil with good results. Dramatically reducing, and in one known case eliminating the clutch pack swelling. NOTE: Gas Gas Spain recommends only Dexron III automatic transmission oil at this time. Oil type warning: DO NOT USE #12378508 GM auto-trac II (blue) oil Never use synthetic oil in the transmission~clutch. The synthetic oils are “stickier” and this adhesion tendency, when applied to the areas between the clutch plates contribute to excessive clutch drag. Some brands of synthetic oil will chemically react when mixed with water, (from creeks, rain, or waterpump seal leakage). This reaction alters the pH factor of the oil. This acidic condition accelerates corrosion of steel engine parts, and loosens the bond of the clutch fiber plate material. Please do not second-guess this information. We have twelve years of experience with the Herbringer/Adige brand clutch plate materials, and we are in direct contact with the technical departments at Herbringer, Adige, and Gas Gas Spain.

I've still got the manual for my 2010 bike that got stolen, there is a table with all the torque figures. You should be able to down load a copy from Trialspartsusa.

What thickness of gasket to use under the barell There is a video on trialspartsusa.com how to measure up the 'Squish' Tthe spark plug gap (manual says 0.6mm but trialspartsusa.com says 0.9mm) I set mine to 0.7mm The tightening torque for the barell bolts Owners manual says; Cylinder stud bolt fasteners 25 N-m. and Cylinder head screws 11.5 -13 N-m. The volume of gear oil, manual says 550cc but this seems to be too much Yes it is too much, fill it half to two thirds in the sight window.

I use Dexron III ATF oil in my Pro models (2004, 06 & 10) and not had any issues

I hope you hav'nt just bought my stolen one!

Stolen 7th March from stockport area; GAS GAS TXT Pro 250 year 2010 Frame No VTRTG2503L0100391 and HUSQVARNA TE250 Year 2004 (Yellow/Blue) Frame No ZCGH800AC4V000635 Any information please call Rick on 07525968468 or PM me

It's prety normal. Neutral is almost impossible to find while the engine is running but is easier to get by hand. or if still rolling.

I was there last Sat the stream was deeper and flowing faster than usual, Got my feet wet. Send me a PM when you're next playing!

Its a bit of personal preference Cheapest way is try a different front sprockets 1 tooth more & 1 less then see what you like

I am on 10/42 aswell

Chain length depends on what sprocket sizes you have, chains are available in all lengths If you are happy with the gearing you have now just count teeth and the links including the split link. many dealers just keep a stock of long chains because you can always shorten them its not worth buying a chain tool, just grind the ends off the rivets with an angle grinder only takes a minute.

I noticed when on the sunny you get more revs at top end. If there is a difference low down I can't tell.

Very common fault after an off the silencer gets pushed inwards and does this, I always check mine after a crash. New ones will be available from GG UK but pricey about

I can't get 400ml in mine but I'm not complaining! Definately fully synthetic 2 stroke oil. I am using normal Shell petrol and Putoline Trials oil at 65ml to 5 litres its about 77:1 never fouled a plug with this mix. ATF is not expensive but try a local auto spares shop something like 'Comma' is cheaper but the DextronIII spec is what to look for.

Most people use ATF DextronIII oil, takes about 350ml or fill to halfway in the sight glass. I fill mine then run a few minutes and check it when settled. Forget the owners book it is full of mistakes! It says put 550ml in the gearbox (it wont go in!) and it also says petrol mix 50:1 when between 65:1 or 75:1 is what works well.

I put one on my 250 when I first started, smooth power delivery and less stalling. A bit pricey but more effective than a head spacer. I believe they are even better on the 280's.

Cooling fan failure will allow the engine to get hot but if you know it was working then; A leaking cyl'head seal will boil the water and presurise the water system. The pressure should all escape via the Rad vent pipe if this is kinked/blocked then the next weak point is the pump seal. Worn/damaged crank seal (right hand side) will create pressure in the gearbox and force the oil out of the breather. Your spare cylinder should fit but the 280 head has a different size inner O-ring seal and is too big diameter for the 250 cyl. ie, the head will go on but the seal will be wrong!

Also soaps and detergents contain Caustic and this eats Alluminium for Breakfast, Dinner, Tea, and Supper. Anodised alloy parts such as wheel rims are a bit more resistant to it untill it gets through the surface.

To do trials run by an ACU club you need a trials registration card, to obtain this you have to be a member of an ACU club. You can get a unique code from your club so you can reg online, or print off a reg form and the sec could sign and stamp it then post it. I think you still need a photograph for a first time application so doing it online might just be for renewalls,

I've got a Kliponoff 'Lite' single trailer and am very pleased with it. CMF Engineering do some trailers that fold in half and then lean against a wall.

Decathlon have quite a selection.
