thanks for that ,the bike has been stood for while by the last owner s ,starts well ,but runs like its on choke still .carb strip and clean? do the chokes stick on this model?

Its probably mixture screw on carb, they are usually about one and half turns out and go from there.

right fellas stripped the carb down ,no probs there took flywheel caseing of oh dear covered in rust ,the guy did say it had been stood for months,gonna get the rust off tomorow plus spray with wd40 someone has sealed the caseing with silicone,shall i reseal or is it best to leave air gap for moisture to get out ?hope the stator is ok ,ime no mechanic guys HELP

please help bought a 125 04 for my 2 boys been stood for a while i was told,changed the oil ,antifreeze new spark plug,bike running like a pig at high revs ,won t clear its self ,took off flywheel all rusty inside cleaned it all wd40 put back together took it for a spin still running bad ,carb been off cleaned ,airfilter ok, bike start s well and ticks over ok what wrong with it .my lads are gutted ,so am i, gone to my limit money wise ,they were into mx but it got too expensive for me, so i thought trials would be the cheaper option i could be wrong. please help

Hi Jack

Sorry to hear its still not running right..

When you say rust ...this will just be the fly wheel weight unless its been taken off...

They are all prone to rust up with any hint of water etc etc.

Do NOT use WD40 (Use a contact cleaner) LIKE IN LINKY http://www.putoline.com/en/products/catalogue/segp_kart/pmp/540/karting/maintenance-products/contact-cleaner-spray-ae/

WD40 will only let any rubbish (DUST /DIRT) stick to the electrical components and build up all sorts of crap

Have you checked the bikes kill switch ? (even on a new bike the beta ones are not the best) if its been on the bike for a long time it may be faulty.

Is the earth lead on the bike clean and fixed down properly ?

Check the HT lead at both ends

If all else fails it may be to strator problem... (i would phone lampkins /beta uk importers 01535 655970) and tell them your problem and they will point you in the right direction. (they have a very good after sales reputation)
