gilera setup business

yoo
ive got a runner 172 and im havin a few little probs,
1st one is the choke, ive never had a bike wih manual choke before so dont really know how to use it lol..im sure ill work it out but the other thing is more serious, every time i throttle it sticks open, just had the carb off and there isnt really anything out of place so i just oiled up the slider bit and put it back 2geva, could it be something to do with the spring?? is this a common problem with 172s? someone help me lol i dont want to fuck up the bike i nearly wrote off into a parked car because of this.
any help appreciated

*updated below*

 

this happened on my runner other night, check the actual throttle cable make sure it isnt frayed and also check the part where it connects to the throttle sometimes if its put on wrong it can be jammed in there

 

kooool it was actually the cable. sorted

 

*new*

right, i changed my plug today and the bike feels sluggish like it doesnt wheelie away from the lights and the power is delayed about 2 seconds after i throttle arc: arc: also when i open it more than halfway it makes that hollow baaaaaaaaaaar noise (thats the best i can describe it) and takes longer to pick up speed.. it wasnt this bad before and surely a fresh plug couldnt make it worse?? could it?.
also it was bogging when i wheelie, only stays up for a few seconds
anyone???

 

If you only changed the plug is it gapped correctly ?

 

had a butchers at my jet and it was a 90 :w00t: :w00t: :w00t: bit lean i thinks..

 

You wanna take your throttle apart and grease the fuck out of it.
It will probably be drier than a nuns cunt.

 

haha good way to put it.
