Does exhaust change affect performance of the bike?
There are several ways to make the engine do more work — enlarging it, making it rev faster, compressing the air intake, etc. An exhaust that flows better will reduce the work the engine must perform when it expels exhaust gases, especially when coupled with improvements to the flow of air and fuel on the intake side.
What causes exhaust to pop when letting off throttle?
Plugged slow jets not uncommon (and that can cause other major problems. If the bike never did it, sat a long time and started popping, that’s more of a possibility). Incorrect air screw settings can sometimes cause it, I’ve been able to tune it out (or hide it..) with an air screw adjustment in some cases.
Why does my bike feel slow at low rpm?
Starting with carb’d bikes, it’s fairly simple. An engine running lean at low rpm tends to feel snatchy and unpleasant. It’ll also need lots of choke and take a while to warm up. If it’s too rich it feels slow and fluffy, as if it can’t be bothered to rev, or for the revs to die back down again.
What happens when you let off the throttle?
Not uncommon, should happen when decelerating in gear, the explosions aren’t as violent, and don’t get as much gas burned, so left-overs happen.
Why does my car backfire when I let off throttle?
Backfiring happens all the time, in cars and bikes, you just don’t hear it because the muffler/exhaust. Since you’ve modified it, now you do. What it is, is incomplete combustion, fuel is left over, and shot into the exhaust pipes.

Why does my dirt bike have too much throttle?
Any number of reasons can impact the performance of the dirt bike’s “gas pedal” including bad maintenance or damage from an impact. “Whiskey throttle” however is all in your head. For the uninitiated, “whiskey throttle” is giving your bike too much throttle, then you start to loop out, panic, and give it even more throttle instead of powering down.
What does whiskey throttle mean on a dirt bike?
For the uninitiated, “whiskey throttle” is giving your bike too much throttle, then you start to loop out, panic, and give it even more throttle instead of powering down. A broken throttle is usually quite evident and typically occurs after a crash or from the careless dropping of the bike.
What’s the best way to adjust the throttle?
By rolling your thumb slightly up and down you can adjust your speed without removing your thumb from the throttle. Pushing against the throttle body, which doesn’t turn gives you a lot more stability and grip to keep that hand where you want it.
