Okay so I have a G series 2 stroke 80cc motor, when I go to try and stop cause as of right this minute I don't have brakes so, what I do is let go of the throttle all the way and I'll push the clutch in, but when I go to push the clutch in all the way, the engine revs really high and this is while I'm still moving! What is going on? Can someone help me with this please

Air leaks around the intake manifold. Ya might need gas resistant glue

Sticking throttle cable or it's too short.

okay I fixed that problem my new problem is,. I'm just cruising down the road, next thing I know it makes a weird pinging noise then cuts out, but right after it cuts out while the bike is still coasting I'll pull them clutch in and release it she comes right back to life and sounds fine. What could that be? I'm so confused. Like I don't understand why I'm having so much trouble with this engine...

that's what she looks like it's a good color, that's about close to the color you want out right?

What you describe sounds like pre ignition (knock and ping)
What octane gas ya burning? Ya need to burn high octane.
Low octane fuel 87 can cause pre ignition - Fuel air mix igniting before spark

By adding oil to the gas it greatly lowers the octane of gas, so if ya use 91 octane by the time ya mix the oil it turns into 89 or 87 octane This is OK

If your using 87 octane by the time ya mix the oil it becomes like 85 or 83 octane and that no good.

Some guys use octane boost

Oh **** okay yeah well I've alot of forums and alot of ppl day it honestly didn't matter what type of gas to use. But okay I'll take your advice thank you. But question how does the spark plug look? That's a good color for it right

I wonder if he's having a fuel-delivery problem, like a clogged filter or something that's keeping the fuel supply keeping up with demand? I had an old car that did not respond well to gasohol in the early 80's.... it would idle and do okay at low speeds, but cut out on the freeway, yet restart no problem.

Fuel delivery problem can also be incorrect float height, a clogged petcock fine filter screen, a gas tank that needs a vent. or your low on gas.

So I'm not low on gas, the petcock is clean. The tank might need a better vent on it. And IDK about the float. I did buy some octane booster tho, like somebody suggested. I'm going to take pictures of it and post it and I just need to know if I got the right stuff. Thanks everyone!
