I had a fall at 10kmph, the rear tyre skidded while off roading after which the handling has changed the bike doesn't corner as well as before. The fall was on the left side and now while riding the bike leans slightly to the right. Also if i leave the handle bar at 30kmph the bike moves towards right side.

The handle was bent so got that changed got the oil seals changed and fork oil refilled. Still the issue is not 100% solved but handling definitely improved. Now whichever mech i take it to tells me that fork is out but i think they just want to make a quick buck. If the forks were bent shouldn't they have damaged the oil seals? But ive ridden more than 2k after the fall and there is no leakage.

Another mech told me that it is chassis bent, i didn't believe him but still gave him my bike because i ran out of options and as i guessed the handling is still the same. Now what else can i try to fix it? One mech tells me there is no problem with the triple tree and another tells me its a bend in the triple tree. What to do?

Also the steering is very light to turn which is good for city riding but for high speeds the hanlde should be firmer, is there a way to tighten it so that it will feel more planted.
