I think this depends what model year your talking about. A reliable source told me that on the 06 bikes the scorpa gas gas and sherco rear wheels are the same. in a round about way I can confirm this. I bought a sherco wheel second hand, fitted the Gas Gas spacers and it worked no problem. I then sold the gas gas with the sherco wheel in and the gas gas wheel went straight in the scorpa, again no problem. I can tell you that the mont wheel is different but you can get a GG wheel to work in a mont apparently by using a different spacer. However I dont think it will work the other way round as the mont wheel is bigger so you would need to change the hub.

This could go on for weeks 1990 As if the scott trial wasnt hard enough on my bike I realised between the 3rd and 4th check that I hadnt put any two stroke in the petrol, no wonder it was pinking........... 1986 At the ssdt back in the days of drum brakes I fitted a new back tyre but was running out of time. Quickly put the wheel in and went flying down the lane to the time control.... only i'd forgot to re connect the back brake and hit the caravan.. 1991 rode a trial at bootle before it was a national and managed to pass birks on the fells, first and last time. He was actually slowing down to avoid the bog I went cartwheeling into.. someone elses turn !!

Fork springs with the spacers are normally longer than the fork at full extension in my experience. Good way to try out if they are too hard is to put a zip tie round the stanchion tube, ride the bike and then you will know how close they get to full travel. Your forks should operate between 1 quarter and 3 quarters of travel in straightforward sections and only bottom out if you are travelling at speed or jump off somthing pretty big. your rear suspension should have about an inch to 2 inches of sag without you standing on it. bear in mind these are the settings I like but it gives you a start point. you should be able to adjust the spring length by turning the collars assuming the shock body is threaded.

lpd i'm puzzled. If the bush has been replaced surely the back end is higher so how does dropping the forks help ? that should make it worse ? You probably need to reduce the tension on the shock spring to get the ride height back to where it was with a worn bush or if the spring length is right then you just need time to adjust ?

The North East Centre has organised them before, Durham County has ran a few. No reason why the centre couldn't again. The new land Tweed Valley have would be ideal, suggest you kick this off sunday at Alwinton, I'll help you out if you want.

Eiger this is all from memory so it will pay you to talk to Birketts 01229 716806. But the 270 barrel will have had the base skimmed to make the the larger piston work. This is because the distance between the gudgeon pin and the top of the piston is about 2mm less on the TY 250 Twinshock piston (the twinshock piston had a bore of 70mm not 68mm) which was often the piston used. If the barrel has been skimmed and the correct piston used the timing should be ok but you may have to adjust carb. You should be able to check the barrel has been done correctly by taking the head back off and at the pistons lowest point the top of the piston should line up with the bottom of the exhaust port. At the top of the stroke the top of the piston at the outer edge should line up with the top of the barrel. The other thing to check is that the reed block didnt warp when it was cut and welded. This happend on my pinky but was fixed by fitting two gaskets. Just check its all square where the reed valve bolts on to the block.

The Raga Rep isnt usually released until April / May so I doubt there will be any info available as yet.

From what I have seen of trials in the USA on this site and talking to some americans at the SSDT I think the US terrain has more traction so you tend to have bigger obstacles. Loads of power is ok if theres loads of grip but no good for tight sections on slippy surfaces. Over here throttle control is key as you need just enough speed to get grip, to much speed / power and you overshoot the obstacle or spin the back wheel. just my thoughts anyway

Funnily enough I went from a 250 to a 300 a month ago. The 300 was like a rocket in comparison to start with but I find it ok now. I think i ride them both about the same, the extra power is useful at times as you can pull higher gears and actually ride slower. The down side is its more tiring to ride.

is the cooling fan cutting when its supposed to ? Trace all the wiring from the stator to the plug and check its not earthing somewhere, check the connections?. very unlikely but are the reed petals ok? quite unusual to get touble with a scorpa so itsa probably somthing daft.

Middle box is as per previous post, its easier to remove and re install if you warm it up a little first. Use a hot air paint stripper, it doesnt take much heat to make a difference. The clutch problem is most likely the wrong oil or it needs changing, what oil do you run ?

Dont forget the cable, I run wd40 or gt 85 down the cable once a month, disconnect from the carb end first. this makes the throttle feel lighter as well.

Anybody know why some people change the master cylinder and hose on the Pro. I've seen quite a few with the bigger master cylinder on with a larger diameter hose and i'm wondering if this would change the clutch action ? cheers

oh alright then I'll play your game Mr Serious Never owned a fourstroke let alone a 4rt but is it easier to tune up a 260 or de tune a 280 ? based on two strokes I would think it would be easier to calm down the 280 if it was too much for you. If you buy the 260 and its not enough you then have to buy the 280 anyway. there it is , a serious response . how about saving the money and grafting the 500cc kit onto it from your dads AJ ? oops I'm off again.......

Pro Truck or Fujiscott, who will spend first ? the suspense is killing me !!

I used PJ1 siver fire two stroke in mine at 65:1 and silkolene light gear oil in the gearbox. No problems with either. Scorpas are pretty bullet proof really just loctite the sprocket bolts, not much else comes loose. Its worth turning the HT coil upside down so that the plug lead runs up the frame tube rather than round the barrel (you'll need to extend the other lead with a connection ) , also zip tie the clutch hose so that its not touching the barrel. both of these mods are just to stop the barrel cooking the lead / hose when it gets relly hot. Apart from that clean the filter and carb every week as its easier to do in the garage than on a windy hillside and everything else should be fine.

thats not a bad idea mate, certainly worth a go if the terrain lends itself

I dont think the vast majority of people who started riding over the last ten years believe the people that rode before then but i'm going to say it anyway. My second trial age 11 was at a place called Rookhope in weardale. I was on a whitehawk ty80 and it was a centre trial with one route. I didnt get through many sections but I enjoyed it all the same. I've marked quite a few trials out in the past but I think the multi course idea is a pain nowadays. I've been criticised for making the easy course too hard before and i've told people that what they claim is too hard for them on a water cooled disc brake monoshock is actually an old section that my dad and his friends used to do on their bultos and montesas. I'm not saying either me or my dad were/are any good but that peoples expectations are different. everyone wants to feel like a superstar and finish on 20 marks so people stay on the easy or middle course rather than progress. the trouble I have with this is that its getting to the point in the North East were the hard course is considered last as it has the lowest number of entries. We therefore end up with lots of tight sections set out around the middle route. How does the sport progress if we scrap the top course ? I think getting back to one route over a period of time is the way forward well done richmond for having a go.

Matt the previous post is quite correct, the raga has a different front brake, some years have a different master cylinder and they all (so far as I have seen) have a floating disc. The disc helps as it means the caliper, which is fixed, lines up exactly with the disc even if the mounting brackets are out of line a touch. Having said that people were doing stoppies on twinshocks with drum brakes so good technique will more than compensate for the different brake can you let us know when you go over the bars ? we've all done it, its just a matter of time !!

You could also fit a slow action throttle if your bike doesnt have one already. Pull the grip back to reveal the tube the grip is fitted to, if its white thats a quick action throttle, you need to fit a black slow action one. cost about

I'd just check things like the gear lever, brake pedal, kickstart and sprocket bolts are tight and that it has oil and coolant. The dealer should check all this but it will only take 5 mins and then you get to ride your bike all day. I think the linkage has seals in anyway so it should be fine for a first run out. enjoy and go easy on the revs !

neutral should be between first and second gear, all the way down is first. Put the bike on a box so the back wheel is off the ground and go through the gears turning the back wheel by hand (better by hand than running the engine in case there are some teeth flying round in there). you should have one neutral and six gears. I'm just thinking your second neutral maybe a gear with no teeth left on it.

I can t say I always enjoy being on the receiving end but the fairest observing from the point rappers is making ( and this is only my experience) is probably richmond. The observers apply the rules by the book and to everyone, they also have the best trials land in the world in my opinion. Problem solved rappers ? I think elsewhere rappers is right. The NE centre has no stop at all centre trials but we also have a lot of tight turns and when you watch the expert course most people are stopping all the time if only briefly. i dont think the easy course people get away with as much.

I can beat that one mate I took the air filter box off my new Gas Gas to seal the joints up and I stuffed a rag in the back of the carb. Reassembled bike with rag still in place and wondered why it wouldnt go. Even borrowed a friends CDI box and swapped that over before realising the mistake. still its a neat trick if your going to the IOM with some mates and like practical jokes.....
