So I posted a problem a while back that I was getting acceleration without using the throttle and it turned out the throttle cord was pinched (that was on a friends bike). Everyone kept telling me that I had an air leak. Now, I know what an air leak is and kind of how to fix it, but everyone kept saying about adjusting the CNS carburetor because it was running too lean? This I don't know how to do. I kept reading that there's a needle to make it more or less lean. So I was wondering if someone could point me in the right direction for a CNS V3 Racing Carb lean setting- unless I don't need it because I'm not sure what the problem is.
And I haven't tried the choke method so I'm not sure if it's an air leak, but I get about 25-30 mph W/O any throttle at all. When I try to put the clutch in for idle, it revs way, WAY too high. The only way I feel like I'm not going to blow up is to kill it then put the clutch in.
-Before above problem-
My bike was running "fine" getting me from place to place w/o too much problems. It was only running at about 15 mph compared to the 25 I normally got. So I decided to take the engine apart to see if I could figure out and problems. I drained the engine, cleaned up the carburetor and got everything remounted (after noticing no problems). The bike ran really well (just like it used to before I started having all these problems) then a loud pop noise and the engine died right away. This was sudden too, no weird sounds then a pop; I was just riding and a pop. So obviously, I got off my bike to figure out WTF happened. Couldn't see any visible damage, nothing was leaking, dripping, smoking, etc. Once the engine cooled off I took it apart again to check the piston rings, crank shaft, all the housing, electrical, everything was normal. I still don't know where that noise came from.
Well I let it sit for a few days and early today I figured I go and try to fix it. Well as it turns out, it still wasn't working. I took it for a ride to try and start the engine (I enriched the oil mixture to a 32:1 ratio, switched out my exhaust for the original one) It kept trying to start it sounded like it would fire once, humm for a bit, then fire a few times consecutively, humm for a bit (all while I was pedaling, repeated this process x8). So on the eighth attempt, i hear another loud pop noise but this time the engine starts after the pop noise. After that it has some extremely hard times trying to stay on, but it accelerated a little bit, it idled; it would almost die then rev back up, almost die (repeat). I let it idle for a few minutes till it was idling a little more steady. It was working pretty good but then I get so far I hear more engine popping and it almost dies, instead losing all of its' power.
So I felt like it was a miss-fire issue or a fouled spark plug. I switch the spark plug out and now I have this acceleration without throttle problem. When I do give it throttle it sounds like I'm about to start flying. When I put the clutch in to try and idle it sounds like the engines trying to idle as fast as a car's engine.
Is this an air leak or do I have some other issue?
