Anything modern is going to be so much better than your present bike.Trying as many as you can may leave you confused as to which is the best for you,there's not a lot to choose between them and they are all good.Ideally you need to ride a few sections,test riding in a dealers car park doesn't tell you much?Can you scrounge a ride on some friends bikes and end up with a short list and go from there

There's a filter on the fuel tap inside the tank as standard,but another can't do any harm

Are the clutch plates fitted in the right order?

Apico will be fine,Putoline GP10 is good in the gearbox

Comprehensive answer

Got an 18 280 rr,fitted slow throttle otherwise standard.Very controllable low down,plenty of go when you open it up,love it .300 is too much for most,brilliant if you're good enough,250 I found not hugely less powerful than mine

Set it to where it runs best,1.5 turns out is weaker than 3/4 turns

Flywheel weight and slow throttle works for me.10/42 gearing i found too low,mines 11/43

It's done a lot to wear the black off .Id look for another bike

I'd replace the clutch plates

Are the areas on the clutch basket and hub where the plates touch smooth,any notching will give a terrible clutch

I wouldn't wear a helmet that old ,they're not able to give effective protection that long.A new one doesn't cost much,certainly less than a head injury

Not as above.If for example the spring is 200mm long uncompressed,8 mm preload means turning the threaded rings clockwise till it measures 192mm

You could take the shock off your bike and compare it

Id check the cylinder head O rings again,that's the only thing that would pressurise the rad to that degree.Does it have a pressure release valve in the top of the rad?if so sounds like it's faulty

Racing and Gp are the 2 different models of a gasgas pro trials .The Gp is a higher spec,carbon airbox,better shock are the main difference,the racing is plenty good enough for anyone outside of world championships

Why did it shear the key originally?

Quickly,cheaply fixed,perfect

The 250 rev 3 did grip well,mainly down to having soft power.The modern 250 is much more powerful and has less flywheel weight,great for steps and climbs with little run up.Once you get used to getting your weight further back you'll be fine ,bit more damping on the shock helps grip,standard is quite bouncy.IRC rear tyre is best when it's muddy

Oil looks very black,looks like its sucked in dirty gearbox oil.Looks the wrong colour for 2 stroke oil.Whats the cylinder bore like,worth putting a piston in it as well while its apart.You deserve a bit of luck with it after the grief it's caused you

Does sound a bit weak,what colour does the plug come out?After what you've changed on the electrics it seems unlikely it's that.Do you know anyone with a similar bike you could swap parts with?

Drilling the bolts won't grease the bearings,the grease will only get between the bolt and the bush unfortunately.youd need a groove in the bush lining up with the hole through the bolt.Used to do this mod on Beta Zeros.It definitely prolongs bearing life,but had a few bolts break where the drilling weakened them

Sadly this happens every week everywhere now and the police don't seem able to do much about it.Can't help thinking that new bikes like this go out of the country and the scum that nick them are informed from some source as to the locations of the bikes,.They seem to get through any security and nobody ever sees or hears anything Wish I had an answer but seeing as there's been a significant reduction in the amount of police and an increase in knife crime I don't think much changing unfortunately

Steves engine was rather more than standard that day,those hills were killing a lot of the other bikes.Steve gave the rest a riding lesson in awful conditions in a classic venue which has sadly been lost to the sport.The local boys struggled all day at a BTC then,much as they do now I think the difference now is the fact that 5ing a muddy climb is unlikely to damage rider or bike,failing a big rock step is a bit different

Assuming it's the one on a certain auction website,it looks good ?The front pipe is nice to have rather than a big performance increase,it might have been rejetted to suit.Check chain and sprockets,linkage swing arm and wheel bearings etc.Get it hot enough so the fan runs and check it still runs well,ignition systems on these are known for problems which show up more when hot. Be good at £1750,how good are your negotiating skills?Lastly is it registered in the sellers name and address?good luck
