Go to www.thehellteam.com Look in CARB AND JETTING on the TECH SUPPORT PAGE - GASGAS INFO.

This is what I have used in the past MFA como drills 457RE540/1 MOTOR with mounting bracket 4.5 - 15 volt 15,800 rpm @ 12 volts www.mfacomodrills.com.

I cut the top off a GasGas pro sump/filler plug once and drilled it out through the allen head recess and that worked fine, do not tighten that bolt very much its about 4Nm torque if I remember correctly . Use a medium strength thread lock liquid.

Being that you are in the USA and have obviously never seen the SSDT in its complete form you can be forgiven for thinking that riders do not sit down for quite long periods of time on their bikes during the Scottish while riding on the road in between sections , although it is a fact that they do and always have. There is a lot of footage of the SSDT on the internet showing riders doing just that . We live and learn. As you say DL 12 is over 6ft tall and I think uses no bar risers and as far as I know uses a 4 1/2" rise bar . He is a 'croucher ' on the bike with very strong legs like most serious trials riders have. He obviously is not hindered by his taller than average for a trials riders height .

Not sure that its an advantage to be tall on a trials bike riding on the trail , overhanging tree branches will let the tall rider know that its not an advantage. If you are an Enduro rider it is an advantage to be tall for example Pol Tarres 6ft 7" who bailed on Trials competition and went over to the tall seat bikes scene. I know who I would rather be riding the Scottish Six Day Trial with all that road work to do on a trials bike , short legs fold up smaller than gangly long legs when you are sat on a trials bike.

i dont think there will be many , Trials riders are known to be a bit shy when it comes to spending money. I wish I had the money for one , the weight of them is the big draw . Enjoy it and buy yourself an AIROH helmet to go with it or you will keep falling over to one side or the other.

Your older trials bike is no different than a current trials bike in the way it feels when stood on it . You should support your self with your legs when stood on the pegs/footrests not lean on the handlebars while riding . if you are tall try using bar raisers or taller/higher bars .Use trials bars NOT MX ones if you do change them , you should also not grip the bars tightly or you will end up having arm pump. The usual way to ride trials bikes is one finger covering the front brake lever and one finger covering the clutch lever at more or less all times but of course you can ride it however you like its your life. The thing about trials bikes is they are designed for competing in trial competition only and they are not comfortable to ride on trails or on the road as they are not designed for that purpose you just have to adapt. If you are 5ft 6" tall then they will be much more comfortable , Bou and Jaime Busto are ideal size trials riders as on the trail they can stand up straight. and their centre of gravity is so much lower which is probably the reason that they are the top riders . If you are taller then unfortunately you need to bend your knees and crouch a little while riding and support yourself with a strong pair of legs.

@Jamiecollins03 Jim to the rescue , unfortunately the good die. He did it for you so rejoice in his life work of helping others FOC. https://youtu.be/PuUGLuUMmOs?feature=shared

The rear shock you have high lighted is one of them or they have a special offer on OHLINS SHOCK GG18330 with a choice of two spring weights for about £100.00 cheaper that will fit your bike , the OHLINS shocks are less heavily damped when set at minimum damping setting than the SACHS ZF {as they come from the factory} so if you like to have a pogo stick rear end for hopping the bike around then this is beneficial I have both shocks and there is a very noticeable difference between the two , the SACHS feels numb compared to the lively OHLINS. I much prefer the OHLINS myself but there is nothing wrong with the SACHS shock it works well. SPLAT SHOP can service your SACHS shock it will cost £174.95 + SHIPPING . As far as i know trials shocks are not just a one fits all but it will be possible to make certain ones fit between different munufacturers by making some changes , but in my opinion it just is not worth the hassle as the 2 X reasonably priced SHOCKS that are readily available to fit straight on the bike are all that is needed unless you are competing in the World Trials Champs. A top of the range REIGER 4 way shock will fit your bike but at a cost of £1,240.00 GBP it may be too pricey but its the best you will get . Good luck with whatever you choose to do.

The Sachs rear shock is rebuildable by people who know what to do but unless you know where there is a specialist that rebuilds other peoples shocks then it will be problematic OHLINS produce a rear shock that will bolt straight on your bike you just need to buy the correct spring for your weight if you are lighter or heavier than the standard spring that is fitted which is for a rider around the 75/80Kg mark , rebuild parts are available for the OHLINS and they are a well known brand so it is the best bet really. If you cannot find one in the USA then try SPLAT SHOP in the UK @ www.splatshop.co.uk , they have them listed for sale , they also may possibly be able to rebuild your original SACHS ZF unit for a reasonable price you will have to ask.

@dirtrider86 There are trials training videos all over YoutTube Pat Smage FactoryONE Motors , Ryan Young , GasGas Get on the gas with Albert Cabestany , cross training trials , trialstrainingcenter , mike haubrich , trials riding 101 Paul Brodies Shop, Trials Progression. Trials Progression is by a beginner from a beginners perspective so you may like to look at his videos as a starter as he explains how he set about his training not just how to execute a technique. enjoy yourself there is hours of the stuff on there.

I think it would depend on how old you are, how physically fit you are and most importantly how much money you intend to spend along with how easy it is to get the bike you want in the area/Country that you live in ?

The answer is to Google Marzocchi 40mm trial fork oil change You Tube or go to www.thehellteam.com in Tech support.

Google 12x19x3mm rotary seal and you will find a supplier.

If drag is a problem and you cannot obtain GRO 75w then try to get Motorex trial clutch oil as it has a similar effect

Hello first thing is to check you have fuel flowing properly out of the petrol tap, turn it to the off position then get a jam jar etc and get ready to put it below the fuel tap when you pull the fuel tube off it to catch the fuel then turn the tap to on and reserve positions to make sure fuel flows freely , if it is slow to flow then you need to take off the fuel tank and empty it before removing the tap and cleaning that thoroughly until fuel does flow freely. Also buy a new spark plug and some feeler gauges then set the plug gap to 0.7mm , next clean ALL the wiring connectors on the bike and make sure where a bolt connects a wire to the frame that it is clean of rust/corrosion and tight. Next thing is to clean the carburettor out very thoroughly and most importantly check the height of the floats/set the float arm position to ensure you have the correct amount of fuel in the bowl , you can find out how to do this on You Tube you probably have a Dellorto PHBL BS 26mm fitted so Google that to find plenty of information about it as its the most common trials carburettor. Hopefully after doing all these things your bike will run as its supposed to if not come back here to find out what the next step is. Good luck.

is that a mistake 80:1 mix in a motor that is air cooled ?

Always by the wheel rim or swing arm.

Makes sense , S3 have been making the cylinders , front pipes for GASGAS for years , these days I have to be careful what I assume as every one these days seems to be seeking ways to have less compatibility of products.

There is the KISS principle.

@Nedly S3 PARTS Spain make a head and low compression insert for your bike it costs £153.00 in the UK I think you should find S3 parts for sale in the USA at a Trials dealer , if you cannot find it then go to www.trialendurodirect.com in the UK.

Not real carbon but www.trick-bits.com. does plastic if you are interested.

@bikerpet as you obviously know what you are doing all I can think of is that you have a crimped/kinked hose and the crushed part of it is not allowing full flow on the brake fluid return to the reservoir so stopping the brake pistons from backing off, it may be worth a check just to tick it off the list.

Michelin X11 will pass MOT in the UK but for those in USA then I am not sure I suppose it may depend on what your State law is?

@woodsman If you have a bad back I would recommend using a wide elastic neoprene Lumbar support belt like ones that are made by a company called Lonsdale or also Everlast make them They fasten with a velcro strip and can be placed and tensioned to suit your preference to give the necessary comfort and support that you require. Every one has a preference of bike power , my personal opinion based on what you have said If you have the money then I would recommend a newer 200cc BETA or a 200/225cc VERTIGO , 125cc bikes have enough power for easy routes but need more rider input to get them through the sections and as you have a bad back it may not be the ideal bike for you , 200cc has more torque available low down so will make it easier to lift the front wheel using the throttle when required plus they do not stall as easily as a 125cc can . I have ridden both and over many years and 200 is definitely an easier ride . If your budget is low such as up to 2000.00 then you will probably find it easier to locate a 250cc bike and if that is the case then I would also join those that would recommend the 250cc bike. Have a great time and take it steady to build your confidence. Best wishes. 80cc will be under powered and hard work even if it will feel light and nimble because of the shorter wheel base ETC.
