gear shift problems

[markrolls88]

i have one of them rubbish chineese import engines and all the gears go downwards to shift up the gears and to shift back to neutral you move the lever up well when im riding say im in forth and i go to shift down its going straight to neutral in all gears but if im moving sometimes i can get it to go down and i have to rev the crap out of it i have done two oil changes on it in the past week because of this problem so im ruling that out

Check your gear linkage for excessive play.

the shifting is neutral 1 2 3 4 5 but say im in 5th ill shift to go to 4th and it goes to neutral then shift back to 5th but sometimes if i shift back to forth again it goes in with some reving off the engine but i cant seem to find first unless i rev it from neutral and it clicks in to first on its on the lever is secure on the shaft it hasnt been dropped and the shaft has no play in it

It sounds like the gears are going into what's refered to as a "false neutral" which means the selectors aren't doing their job and pushing the gears over properly. The gearbox isn't actualy in the neutral position, it just feels like it is as the gears havn't selected.

If you're lucky, it won't be a gearbox problem and, as Damon suggests, could be the gear lever or linkage fouling and not pushing the selector forks far enough.

It could be down to clutch adjustment but I fear it is just because it is Chinese.
