Aerox losing revs and power up hills, HELP!

when i hit a reasonable hill my aerox loses revs and power it happen about 2 months ago, aswell so i put new rollers in and it was top notch, then it happened again so gave the whole vario a really good clean and it was okay and its come back! :banghead:

one of the plastic ramp guides is it has snapped a tad? or could this but be my variator being knackered, or is it litterally crap in keeps getting in!?
polini hi speed with polini rollers by the way

any help would be much apriciated!

thanks, dan

 

whats the year of bike , my mate brought a 07 with 5g rollers in and he could hit 50 but when he went to go up hills it would die , turns out his main bearings are fucked try wiggling the crank around and that , the variator will only get fine dust on it wont do that affect and anyway you can buy the guide rubber things there like 3 quid and might help

 

2007, its done 15,000 miles though, which is alot really isnt it?
thanks for the reply btw
and the revs drop aswell though, i think it might be the bearings now you've said, you said wiggle it, taking the variator off would do this a tad, i took the rollers out today cleaned them and put em back in and it did it a little bit by not as bad... :-/

 

hmm yer grap both sides and wiggle it , usually 15000 is allot and its probably been ragged , i would say the bearings have gone ill be happy if i get this right

 

cheers mate, ill have a go ad giving it a "wiggle" haha it seems better since i cleaned the rollers again though! could it be a carburetter problem?
