Alternatively measure (ruler will do) outside diameter, inside diameter and the thickness. My local agricultural spares place has always found what I wnated and its heaps cheaper than a specialist trials shop. I've also used simplybearings website which is dead easy to use as well.

2% is by the book which I think is 50:1 but most people myself included go about 80:1, I use 63ml / 5L of fuel and no body's dead yet!

The rattle is completely normal for a gasgas, as long as it disapears when the clutch is pulled. Yes you should see oil in the window when the bike is held completely straight up right. I'd drop what ever is in the bike now and refill, ATF seems a popular choice.

Ah,so, 164mm rear travel = 54mm sounds reasonable, too the tape measure!

I keep meaning to have a look at this on mine. How much laden sag should I be aiming for when measured at the axle?

Correct go for it.

Check the settings of your clutch pack, I believe its simple to alter the feel of the clutch by altering the finger height via clutch pack thickness. There's some good how to vids on youtube from GasGas USA.

Change the plug.

I think a little lubing with 2T oil is the order of the day, not sure about more oil in the premix but I'd think it would be a good idea, someone more knowledgable will no doubt be along shortly. Where'd you get the piston kit from?

63ml / 5litres which I think is 80:1, runs well plug colour good.

Go back to AtF, cheapest and quickest potential solution.

Those that have ridden the wee scorpa 4t's love 'em, myself included. I did not ride the 175 racing version, just the standard one, but would think it would be an excellent lower end clubman bike. I'm certain that the majority of clubmen riders would loose less marks on a smaller/less powerful machine. I rode it a great deal for about 18 months and sold it for more than I paid for it at the first attempt. The combination of a simple durable low maintenace air cooled motor in a gasgas chassis is very appealing to me. I like my 200 pro but can't help wondering when the first engine rebuild will be needed, done the kickstart pawl and gear twice now.

A bit more info available if you google the gasgas Randoner name, and an explaination for the name perhaps: "Randonn

Would be a pretty much perfect for me, wobbly clubman level. Should be priced well there are loads of the yam 125 engine about in various machines, and lots of tuning options available too. Bring it on GG!

Ta for the reply, after walking away from it and coming back fesh and unflustered I can see I have assembled the shaft incorrectly, I got that very strong circlip thing the wrong side of the aluminium top hat spring guide, henc ethe loss of about 1mm worth of movement. I did file a small flat off the edge of the top hat in line with the bulge in the crank case where the enging mouning interferes with it which made it a lot easier to wriggle in and out. Yes Jim makes it look very easy. I hope the 08 verison of the shaft leads to a more reliable assembly. I really dread the thought of those little bits swilling around inside the engine. I wonder if it is worth mounting one of those neodymium magnets between the bash plate and the clutch cover to try and catch the bits which come off the gears http://e-magnetsuk.com/magnet_products/neo...cked_discs.aspx

I'm having a bit of greif getting a new kick start shaft to fit properly into my 07 200 pro. I'm renewing the usual damaged kick/idle gear as well as the shaft and it's pawl, I understand that the 08 shaft has a quicker helix which helps with the engagement issues (it looks a shallower helix as well). My trouble is that after wressling the shaft assembly spring etc back into the case, which is a mission all on it's own, the pawl cannot drop away far enough to miss the idle gear on the kick start return stroke. It looks to be only a millimetre or so and it would miss it, very frustrating! Any clues? It's driving me mad.

I'm thinking about freshening up my 200 pro, it's sounding a little rough now I suspect the mains are getting on a bit, just wondered if anyone here has done a fairly comprehensive rebuild either themselves or a dealer job. I'd be looking at doing rings and little end, mains(not big end hopefully) and the kick start gears + whatever bearings there are in there while it's all apart. Any clues as to expected costs would be appreciated.

Might be worth checking the routing of the hose from m cyl to res, it can get snagged on the shock if you bottom out and then pulled out of the res.

Try Mike Husband at moto merlin, very knowedgable about the pamps. http://www.motomerlin.co.uk/ phone/fax 01403 257626 there is also a owners group on yahoo groups which might be useful to you. Gronno

what John said. Having said that last time I tried to download the form from the ACU site it was the wrong form (or it looked like it was wrong).

Not sure where to post this really but thought a club might be interested. http://www.vantageland.co.uk/land-for-sale...incolnshire.asp Nothing to do with me and I have no commercial interest.

Is the mini Maj frame any lighter than a std TY175 frame?
