Sounds like a kid banging on a pot on the kitchen. Pang, pang, pang...

2005 Polaris Trailblazer 250 Engine Noise - Knocking Sound - Panging Sound
Noise goes away at full throttle but sounds very clangy at 1/2 throttle
audio on video doesn't really relay the sound very well...
idles down very slow
help me diagnose please - sound is coming from front of motor @ ex mani


thanks for the help in advance

Hi,

Welcome to my first post here. I am Jeff from Raleigh, NC and thanks for reading about my problem.

I recently bought a trailblazer 250 - '05 model. It is my first Polaris - I know absolutely nothing about it. In fact, it took me well over an hour to start it up the first time once I figured out that the red light switch was in fact a faded out, engine on off switch.

Today is the first day I actually let it warm up and ride it, I rode it for about 10 minutes before I realized that there was no 2cyl smoke and assumed the oil pump thingy was not working so I premixed two gallons 50:1 (hope that was right) . And I hope that by running it for a few minutes oil'less didnt damage it too much.

I figured it'd be easier for people to help me if I posted a video - which does not really convey what I am hearing (thus) the pang pang description.

Rod bearing, wrist pin/piston slap, valve to piston clearance........

no vales in a two stroke......
time to tear it down OP.

just the top or the whole thing

start with the top. you may find a wrist pin bearing gone. you should be able to tell if there's a crank bearing gone as well by pulling up/down on the con rod or spinning the crank. running without oil is BAD.....

it was about 5 minutes maybe, how quick will it go you think?

top looks pretty easy to do, actually, looks real easy - probably needed to be gone through anyway.

I appreciate the input though

Could be your spark plug. I installed a new spark plug on my trailblazer and it was doing that and then i loosened it up a little and it went away
