hi there,had bike out with gas gas carb on it and alls well,was running perfect so definitely the carb,,just need to get some new jets and see it that fixes sherco carb!!

no problem!!! beats paying stupid prices for a little piece of rubber,everything on trials bikes seems be a fortune these days!!!

Hi there,sorry for late replies,not been near a computer for a while,i,ve got the carb changed over from the gas gas ,going to take it out this weekend and try it,It starts and runs fine with the gg carb on in the garage so hopefully it works,thanks a lot about trying your electrics,i`ll let you know how i get on at weekend,im not far from you,cheers

Hi there,i had this bother a few times,i took my pipe with me to a car breakers yard,there is lots of cars with hoses with the same shape/size pipe if you look around,i just cut a few so i have spare ones ready to go on when i need them and its free!!!!!!

im goin to order some different jets,im tempted to try my gas gas 250 carb on it as its the same carb but i dont know if this would work with it being the 250,might be wrong but is`nt the shercos a 272cc anyway. thanks a lot!!

it does feel like that,I`ve had the fuel filter off since i`ve been working on it and trying out the bike,its getting good fuel from fuel tap and through hose,,Its becoming a mystery!!! thanks for reply!

hi there,thanks for reply,i have sorted the choke lever now but as you say i think i`ll order some different jets and see what happens,I`ve been running bike on 15ml to a litre of fuel so 5 litre/75ml of 2 stroke,it has`nt been fouling the plug,do you think that is an ok mix???

Managed to get bike out to try it and its still the same,I stripped carb off again,took all the jets out,blew them out etc..the jet sizes are 30 and 126..I greased idle screw again incase of leak there and fuel valve is fine,, The one thing i noticed is when i took out the choke lever on carb to clean the lever with the spring on it that goes up and down when choke is pulled/released isnt straight,it has a bend on it so i straightened it as much as i could without fear of snapping it,Still wasnt right after trying bike again..Think the choke lever could be problem??????? thanks

hi,the jets are ..30 and 126,cheeers

puch

we are covered in snow just now so not been able to get bike out yet to see if its any better after cleaning fuel valve and trying grease on idle screw to seal but just by revving it in the garage it still doesnt rev cleanly i would say!

not yet,havent had time to check yet,will check soon as pos and let you know,thanks

The banjo filter was a bit dirty when i cleaned carb but didnt have too much crap in it but i cleaned it all out. I took off fuel valve,it was quite stiff to turn valve,this normal?? i stripped it and cleaned it and blew it out.there was some crap came out of it so hopefully that could be problem,it started up and ran fine but didnt take bike out as it was dark so i`ll post tomorrow when i try it out,thanks again!!

Hi,im not sure what size the jets are,im going out to the garage just now,will try the things that people have said and see if i have any joy,,wish me luck!!!!!!
