hi guys, i recently bought a SuperPower 70 2010 model in black as slight used from a friend of mine. When i got it tuned first time the bike began "missing" upon achieving higher speeds. Bike use to run fine if i keep it near 40 or 50 km/hr. but when i throttle it to go faster it begins missing like the bike behave when it running out of fuel.
i went to mechenic to get it checked. he checked everything then he removed the seat, n checked the Air filter housing (some mechenic call it LOTA) the end point of that housing was too narrow. so he wider it with help of blade n cutoff extra rubber. then he again tested the bike, but nothing changed. then he again tuned the bike but still their was no change. after that he again put a wire on end of air housing and made it narrow again. or in other words decreased the air intake.
then the bike somewhat get better. but the problem is still there. i some time feel that bike is missing when i use to accelerate alot on 3rd gear or 4th gear. i also have noticed that there are petrol stains on carberator. most of the time i use to have smell of petrol. is there anything wrong with carberator ? or is there anything else thats causing the missing issue. should i put a CG-125 carb in my SP70 ? as i have new carb lying around.
your problem is in carb .. mostly there is some leak b/w the path from carb to head .. also thoroguhly clean all the jets .. and screws ..
and make sure ur float level is ok .. i suspet ur float level is out of order ...
