1)

 

Check your vacuum tube. Its a small tube that is connected to your fuel tap under the tank from the left hand side engine block behind.

 

2)

 

If you have recently taken out your tank, take it out again and pull out the smaller tube stuck under it..this tube is a fuel tank breather tube. If starved..you get the problem you are encountering as describe. Next time cannot start again or you are starve off fuel again, just open the tank cap and see if you hear a hissing sound..if there is..its that tube I'm talking about that is starving off fuel.

The problem has been like this for about a days...have been riding the bike for a year and there wasnt any problem before...i have problem dropping gear..When im riding and regardless of the gear i wunt be able to drop gear,like the gear lever became 'soft' i have to kick down atleast 10 times before if can drop gear,bt i have no problem going up gear..even if the bike stall and i wanna drop gear is still soft...i cant figure out the problem...ive change clutch cable,change EO,change clutch plate...even adjust my clutch lever far and near but still the same and when i up gear the 'tok' sounds louder then normal..could it be the gear shaft? ive already try changing wat i though could be the problem..if there's anyone who know or has been through the same problen please share...

its has nothing to do with the biting point or how far or near the bitting point is...even when the bike stall and i move it back and front abit so that i can find the neutral gear the foot gear lever is soft...wat is making me worried is that when im riding and need to slow down besides only using the brakes i'll use engine braking but i wuld be able to drop gear....

Vtec series uses sensor for speedo.. price is alright for changing of sensor as it's a lot of hard work to replace it..

Vtec cant open doesnt link with speedo sensor.. you might wanna check your vtec sensor..
