Default Clunk sound and backfires into the carb

This don't happen alot but once here and there when u tap the starter u get like a kick back clunk and backfire into the carburetor then u tap the starter again and it's fine.... Is this normal for bikes to do every now and then? I heard of bad compensatory in the past is this this mean that's going and whats that have to do with starting? I was kind of hoping this is a Normal thing since it don't happen every day

It needs a new motivator.


Seriously though, you can get any bike to do that on command if you just tap the starter. Push it till it catches some fire in the cylinders.

The starter is made for starting...


Don't 'tap' the starter, hold it down until the engine starts up. Of course, this is only good info if the starter actually engages, or you aren't just trying to turn the engine over a little bit for some reason...

When you 'tap' the starter, it either only partially engages (which may muck up the starter pinion, or ring gear teeth), or it rotates the engine a small amount. When you rotate the engine a small amount, it pulls slack out of the primary chain, and puts pressure on the compensator. This can cause the engine to stop rotating just before Top Dead Center, on the compression stroke. Which is likely to cause a backward rotation of the engine, expelling gasses through the intake and out of the air filter...

Yeah, it's kinda normal, if you don't use the starter properly.

Just noticed...

You've been a member since June, 2008. If you haven't learned what a 'compensatory' is yet, then I can't help ya. If yer just pullin our legs, well, pull the one in the middle. You'll get a much more satisfactory response from that one...

Every now and then my starter clutch will grind or make a loud clack... it's going the way of the dodo bird. Yours could be doing the same.

I allways felt it was normal it happens the second u touch the button I let off fast wait a second hit the button again and it's fine it only happens once in a blue moon... I heard a bad compensator can cause something like this... I guess I'll worry about it when it happens with every start and not once here and there

Nah, look in the upper right corner of my post, and you'll see where I'm from...

Not your typical NY *******, I'm an ******* with a surfboard, motorcycle, and a fishing boat. And if your other banking habits are similar to this one, yer probably broke...

Possibly a weak battery. Have it checked/charged and see if that helps.
