my blaster runs but it take about 4 kicks and then it doesnt idle well until i've run it a few minutes. im sure my carb is out of whack plus i lost one the idle screws on the side of my mikuni carb. well i guess they are all mikuni if they are all blasters (stock anyway.) I was wondering if any one had any tips of tuning a carb and where i can replace one of my idle screws. also if any one has tips on how to repair exhaust leaks that would also be helpful thanks alot to all you blaster experts out there.
blaster runs but needs tunning.

if its on the side of your stock carb then more than likely it wasnt an idle screw it was a fuel mix screw. which if you dont have it wont be adjusted correctly. first off do you have any mods? if not then the jetting should be fine. next go to a dealer and get the screw you need and replace it... the screw should be turn the whole way in to stop then out 1 1/2 to 2 1/2 turns any more or less and you need to adjust the pilot jet. this should fix your problems if not you may have bigger issues.
http://kenoconnorracing.com/Carburetor jetting.html try reading up on 2 stroke tunning 1st thing! im not sure what screw your missing the idle screw on the stock carb would be on top of the tors unit. maybe show a picture and we can figure out what your missing. i have lots of spare carb parts if you need anything. exhaust leaks are best fixed with a welder. how bad is the exhaust?
Missing an idle screw is definitely the problem. You are going to want to replace that. Also where is this exhaust leak on the exhaust? Pipe? Silencer? In between pipe and jug?
surferjag: when i hit the throttle is makes a sharp wheezing noise every so many seconds. i think i may be affecting back pressure. and its hard to tell where its leaking from cause it only makes the sounds when i hit the throttle. unless you guys know how i can tell easily. ?
if you dont have any noticable holes in the head pipe. more than likely its coming from where the pipe meets the engine.
No oil filter on a blaster. Oil for the clutch/transmission goes in at the plug on the clutch cover.
there is no damage. i was riding in my field that is very bumpy where my exhaust meets engine came lose so i put a couple screws in it which was probably not the best idea. i also put one screw where the the muffler (new to parts terms.) meets what i believe is my silencer.
oh sh!t. do you put oil in the gas? or do you fill the oil tank on the back of the bike under the seat? thats for the engine. to oil the tranny you take the drain plug out of the bottom of the engine on the very bottom. let it drain for 20-30 min. then take the cap off the oil fill on the brake pedal side of the engine and fill it with 650ml of your favorite tranny lube. mine is belray 80w
Best airfilter there is imo
Uni Air Filter | Rocky Mountain ATV/MC
And oil for it
Uni Foam Filter Oil | Rocky Mountain ATV/MC
