Kx 85 problems

[welsh.Z.S.]

Hi guys I know it's not a gasser but thought u might be able to help .. my mates Bought a kx 85 that has a few problems .. first problem is when u kick it into gear unless your revving the tits off it it'll die .. and the second problem is any sort of small hill it'll bog down an die , but on the flat it rips tidy .. had the carb cleaned which helped a bit .. the bike starts up easy enough and will idle for as long as u want it too ..
