It doesn’t have a head insert to change, according to the manual/ year. I did wonder if it had a high comp head but the weren’t fitted that year.

Two other people have tried it and they couldn’t believe how sharp the delivery is, one said it was sharper than his 300 pro, maybe wrong jetting?cannot find carb settings to check it out

Hi all, just recently got a 250 pro 2011 and the power delivery is very sudden, the bikes not done much from new, original chain sprockets ,tyres etc. Gearing is 10/41 map is set in rain mode,slow action throttle fitted. I have a 2013 300 sherco which is a lot smoother to ride and I’m really surprised how bad the gasser is! Any thoughts? Maybe jetting or needle position? cheers john.

Thanks for the replies guys, maybe the rebore will give me oomph! I find it very flat at low revs but is fine mid to high revs. Crank seals have been replaced and electronic ignition fitted

Hi guys, I'm looking to get my 1978 ty250 ported as it's very flat at bottom end power,any recommendations where to get it ported/ rebored?

hi, i would recommend vee rubber trials tyres,they are soft compound and the tread is alot deeper than the standard fitment tyres.if i remember correctly the rear is a radial too

hi again, just found out that the coil is an updated part but unfortunately there is no info on the way to wire it up! any help would be appreciated!

hi all, the coil packed up on my sons 2002 rev 50,the new one arrived today but it is a different make(leonelli-old one was ducati) also the wiring is different. the old one has 5 wires( white,red,green,black,plus a blue earth connector) the new one has6 wires(brown,white,red,green,plus two small wires blue and brown) tried to call beta today but are closed,is the coil the wrong one? or an updated part? if so can anyone help me out with the wiring? many thanks, john

You filled them with the forks out, springs out and compressed didn't you? You can down load the manual from the Beta Uk website or email them for a link. couldn't find any info for the 2008 model-have searched and some say 180ml per leg, others 220ml per leg and 350ml per leg

hi,i'm looking for some info on my son's 2008 rev 80(big wheel), looking for fork oil quantity ,i drained the old oil and only about 100ml came out of each leg(fork seals were blown- been told that the quantities were 370 right and 350 left)-is this correct? forks seem quite firm with preload and damping fully backed off. also can the cylinder be rebored or is it plated?

hi all. can anyone supply me with the correct carb settings on my son's 2008 rev80? float height, which needle groove/ air screw turns many thanks john

it's about time we get a youth round in scotland, after all it is a british round! the scottish round in 2013 is still a 3 - 4 hour drive for me and my son and that's the closest one!i do agree that the amount of rounds is probably too much but surely it could be maybe 5 rounds counting out of the 8?

hi, broke mine about 7 years ago at a trial and the doc said that being in my thirties it was going to take a long time to heal,so they put a screw through it to help it heal faster but it still took 3 months.

hi, i had the same problem,but if you leave those spaces blank it works!!

hi,my son has just upgraded from a beta minitrial 50 (auto) to a beta rev 50. the rev is quite a lot larger a bike but he has got used to the extra size. he is 8yrs old and quite small for his age but the bike has improved his riding. here is a clip of him on it to give you an idea of size.

hi, i've used /www.motorcycledeliveryuk.co.uk a couple of time and they are brilliant. i can't fault them and are pretty cheap-hampshire to aberdeenshire

hi, my ty250 went flat, crank seals were to blame

hi,did you replace the crank seals? my ty250 did the same thing starts first kick but wouldn't rev changed the seals now perfect

hi, its is 2005,its is in very good condition and the exhaust is clear as is the fuel tank breather and fuel tap

hi,i'm having a few problems with my son's bike basically it won't tick over i've read all the posts on this topic and also phoned beta but still the thing won't keep running. i've cleaned the carb countless times,changed the clutch,changed the reeds,changed the spark plug,i called lampkins and they said to replace the carb as they are a problem. i ordered a new carb and after 3 weeks it eventually arrived the day before the next trial,fitted it and it now runs worse! another problem is that they recommend a champion L78C plug(NGK B7HS) my bike came with a NGK B7ES which is alot longer than recommended, the head thread length is right for the longer plug or is the shorter plug to reduce compression? i've tried both plugs but no difference! also i posted a thread before to see if there are any better tyres for it other than the cheng shins on it but didn't get any answers can anyone give me info on any of these problems as my son is begining to nag me! many thanks john

hi, i have a 2000 321 and its a fantastic bike,i've had no problems with it,with loads of bottom end power it's very easy to ride and really no need to use much clutch work.i've ridden new stuff and i wouldn't swap it.

can anyone suggest better tyres for my son's bike as these seem pretty useless,the new gasgas txtboy spec lists michelins on it,is this correct? and are the any good? many thanks jock.

hi, are gas gas rear shocks rebuildable? can anyone recommend someone who repairs them or do i have to pawn the family silver and buy a new one? it's for a 2000 txt321 cheers.

thanks,will give it a try

hi, can anyone give me advice on the jetting of a 2000 txt 321,at the moment the main is a 120-pilot is a 30-needle is in the second top groove and air screw is 4 turns out. the bike at very low revs seems a bit rich but is fine at all other times,are they like this?or will i change to a smaller main/bigger pilot? many thanks
