I must admit that my rose-tinted glasses have been getting the better of me on ebay recently looking at ty, s and fantics, I'm glad you put that and I can imagine its exactly what I'd end up doing myself lol. A mid-late 00,s sherco or gas gas is probably the most sensible option cheers

Thanks for the comments everyone, I had my eye on a 2003 scorpa sy 250,looked very well kept and sold before I could get there. I think I should stretch the wallet open abit more and go for a beta evo, I did like my old rev 3 tbh.

I do like the look of the scorpa sy 250 and there is a few for sale at the moment, I like the idea of the air cooled older bikes as well no more '' why isn't my fan kicking in'' has my thermostat gone again lol. Why don't hardly any manufacturers make air cooled bikes any more?? I'd have thought thay would be very popular and easy to manufacture. The tyf125 looks like a fun bike but you don't see many for sale.

Sounds expensive to me unless it's an absolute beauty, I had 2 rev 3s over the years it was a great bike. only slight peeve I had with it was it was a left hand kickstart,and apparently the magnesium casing can become pourus near the water seal but neather of mine were.

Hi all iv been watching alot of the 80,s 90,s and 00,s World trials videos over the past few weeks as i injured my shoulder mountain bikeing. And obviously now I want another trials bike to injur my other shoulder on lol, looking at what alot of the 90,s bikes are capable of how much better realy is say a 2009 evo or rev3 over a 1999 techno, especially from a novices point of view. Obviously if your splatting 6ft rock faces I'd imagine the slight weight reduction will help, but from a middle of the road novice point of view? , Iv had a few bikes sherco betas gasgas all old ish early to mid 00,s versions iv got a budget of around 1500-2000 but thinking shall I go the other way and get say a beta tr34 or twinshock do I realy need a shiny sherco st or something cheers.. ?

I found pretty much all the decent carbon helmets we're around 900g. The lightest cheap helmet I found was the spada edge helmet.

It was originally designed by a South African chap called puzey

Ahh though you would of had to do a welded head tube job, I don't trust my welding abilities well enough to do a head tube lol. This bike goes by many names, it's a puzy rocky, a Cleveland ffx, a jumper 125, a stag rocky. A probly a few others, it's a great bike to modify, it has the fuel tank inside the frame and has pretty good geometry for a Chinese bike.the foot pegs are way to far forward from new to be used as a trials bike, but it's an easy fix to be honest.

Here is a bike I did a foot peg mount modification and welded some bash guard frame rails in, added a gasgas rear wheel and mini brake mount it was a pretty cool bike. I'd like to do a cub 90 next.

How did you get the head tube of the triple clamps to fit through the frame, iv looked at a few honda cub/c90 frames with the idea of doing a off road mod but the head tubes have all been designed for a old fork with a very thin head tube. Cheers.

Just out of interest today I was looking for the geometry of a beta rev 3, to compare it to a beta tr34 from the late 80,s just to see how much bikes have changed from that view point. after some Internet trawling I could not find the geometry charts for either bike, in fact not much info came up for any make which I was supprise about. I do abit of mountain biking and geometry charts are easy to find for pretty much any old shed, I'd would have thought with trials being a very technical sport geometry would be discussed a fair bit on here. Does nobody give a **** about the geometry of there bikes in the trials world or is it just a mountain bike obsession cheers.

No it's an odd length, with the piggy back at a slight right angle to the upper mount so most wount fit, after some research online some older tm 250 shocks are the same, but you don't see many up for sale.

Im just doing a refurbishment of a gas gas ec 250 2005,and found that the lower shock mount is cracked near the shock station so un repairable, I can't find a suitable spare, so does anyone know of and other manufacturers shocks that fit this bike cheers. The shock is 430mm eye to eye.

Had the same problem on a 1998,tx, it was a work kick start spring, lean the bike on its side, take the side casings off you can leave the clutch cover in place, you may have to drain the cooling fluid from the rad and remove the water pump pipes, you can leave it in place but it makes it easier just to move them, take the kick start gear out and check for damage and bent spring end's whare thay house in the casing, mine was a bit bent from use. Check your water pump gear whilst you're in there.

Thanks for the quick response, was hoping you would say that, il have to purchase one of them for my bike cheers.

Check gasgas. Com manuals iv had a few off there. Thay are not like a Haynes manual but better than nothing.

Try a short fox float or rp air shock thay are cheap lightweight and easy to tune for any weight, im 13stone and is not dead yet lol. Think its 165mm eye to eye you need.

Hi yrocmoto could you do a test on the bike for me as id like to buy one of the battery's, can you put the bike on full power settings and do some full throttle tests little pop wheelys and stuff, my battery used to trip out pretty easy, but it wasn't as expensive as that one so it was probably the bms rating thanks.

Hi just reading the posts seems like an interesting battery potential, has anyone actually ran the battery on full power and used it for splatting a wall or log,??? as i brought a similar battery a Panasonic 1200w 18000 ah it was a good quality battery and it worked ok pottering about on it, but if used by an adult splatting logs or quick wheelys power climbing, it would cut out and you would have to switch the bike off and on again, cheers

I think that would be fine but the actual boost battery made for the bike is pretty much the same price and comes in a strong casing, plus boost battery's are an uk company,so any problems will be solved alot easier than dealing with someone abroad. Check alexpress i brought the Panasonic lipo off there it was very cheap and pretty good quality.

Sorry Im lost on this one mate.

Just pop the rotor off then you can rule out woodruff key snapping, iv had two break one on an old yz125, and one on a freshly rebuilt gas gas txt 270,it took me ages to find out it was the woodruff key after taking a multi meter to ever electrical component....

Ahhh its oil on the crank, i was under the impression it was in the flywheel stator housing, it could be the seal gasket if you know the seals have been fitted correctly, could d it be pulling oil in between the casing gasket on the induction stroke, did you notice any pressure coming out the gearbox breather pipe when it was running, it could be a pinched crank case gasket or warping on the face of the casing.

You may have an overly worn crank shaft,pitting on the crank shaft can stop a new seal creating a good seal, or you may have forgot to fit the tiny seal springs on the new seals assuming thay are the type that come with seal springs, did you grease the seals before fitting them?.

A backfire on a two stroke is usually down to timing, to advanced or retarded, position ofvthe stator plate, or broken woodruff key, causing the fly wheel to move slightly out of position, this can happen and the flywheel still seems tight on the crank shaft and has just spun out of place a little.
