thanks for all the advice going to have a look monday night going to get a jitse screw ordered and check everything thats mentioned will keep you posted

the plug did seem very black and coked up

cant beat new shape navara awesome power and comfort

tried new plug it didnt make any difference also checked cap to make sure that was fine, bike was running fine for about 20min previous then went slowly down a fairly long bank just using engine braking

taking it steady then the at the bottom when i started to throttle away the problem started ??????

after some advice i have a 08 4 stroke that for some reason wont rev smoothly ticks over fine have drained the fuel and filled with fresh just in case of any contamination and also stripped and cleaned carb twice and still no luck as soon as you try throttle it coughs splutters and backfires any advice welcome

have taken the plunge bought a mint condition 08 rev 3 4t am finding it very easy to control but only had 30 min on the drive with it due to the snow looks like im going to have to wait till next weekend to give it a full test

may have been a one off have had a quick go on a couple of monts and never really noticed but they were only quick goes but not had chance to try the rev 4 yet

must admit am tending to sway towards the beta rev4 they seem alot better priced than the mont and to be honest fingers crossed the rev 3 has never let me down with any of the problems reported by others so am fairly confident about build quality and i plan on upgrading bike every year so dont really have to worry about any long term problems , will have to test one and have a word with the local dealer

cheers champ will have to take you up on the offer sometime have heard the beta is softer to control

dont seem to be many around for the amount i can afford but the mont seems to look slightly better and sounds awsome

looking at getting a new bike around xmas time i only ride for fun will have around 3 grand to spend after some advice whether to get 08 beta rev 3 or a 05/06 montesa 4rt im currently riding a o6 rev 3 which i enjoy but cant make my mind up whether to make the jump to 4 stroke i think they may suit my riding style any advice welcome

thanks in advance
