It may be just the normal 2 stroke sound.Post a vid of it running.

I dont know about anyone else but I certainly didnt rebuild your motor!

Ja post a video, its impossible to help you with such a little info

Could this be a banned member

 

[haydstah]

the u was a typo i ment i but i think it might be piston clap ill post the vid

 

[Surfrjag]

is it at idle or just when you rev it?

 

[haydstah]

mostly when it idels u can here it bad but when u rev it not so much

 

[haydstah]

how do i post the video?

how do i post the video?

use a site to host your video....like utube. Then copy the URL into your message.

When I (oops U) rebuilt your motor did you bore it? What exactly did you do?

 

[haydstah]

just a normal rebulid piston and rings

 

[Blaaster]

Why did you rebuild, what did the piston look like?

Pinging is usuall caused by lean mixture.

 

[haydstah]

i had to rebuild it because the motor blew and a piece of the piston acutally broke how do i just my mixture? i have the oil injected

 

[Buffalowinger]

It's not the oil mixture he's talking about, it's the air mixture, which is controlled by a little flat head screw on the side of the carburetor.

isnt pinging related to a low octane issue in the fuel...theres a big diffrence between piston slap and pinging from low octane fuel

What did the top of the piston look like and what part of it broke. The reason I ask is to determine wether the piston was fried due to rebuild.

Have you leak tested the motor, if you have just rebuilt it is the first thing that you should do.

Pinging is also known as pinking, detonation or pre-ignition.

Can be caused by heaps of things including, low octane fuel, lean mixture, timing to far advanced, carbon deposits, wrong heat range spark plug ect.

You are refering to the air mixture/idle screw which only (wait for it 8-|) effects the idle mixture ONLY.

 

[haydstah]

should i have it let less air in or more?

Shall we start again, this is going round in circles.

What are all your mods?

What is your jetting?

What part of the piston broke?

What did the rings look like before rebuild?

If it was pinging before rebuild, and doing the same after rebuild, there are a few things you should have done to correct the pinging problem.

Some of those things include doing a leak down test, checking if the fuel is flowing into the carb and it is not blocked.

A slipped flywheel putting the motor into advance can cause pinging, as can changing the octane rating of the fuel.

Please answer the above questions to the best of your ability, to give some information we can work on to help solve your problem.
