One Way to Quickly Destroy a Two Stroke Engine

How using the wrong type is piston pin clip and or installing it incorrectly can cause it to destroy your 2 stroke engine.
Video demonstrates how to inspect and safely fit and remove the piston pin circlip / snap ring.

This has happened to me before on a motorized bike using these clips a couple years ago.
Didn’t know this was the issue I thought it was random.

Glad I watched this video now that I’m working on 2 strokes again recently.

It's aggravating seeing people act foolish on youtube and get paid well while we have you actually trying to educate people and can't catch a break. Thank you and Keep up the good work as long as you can.

Watched this after fighting putting in my 1st surclip.. i definitely bent the ears.... thanks buddy

[thomashowlett]

I did not know this. I had never really considered the orientation of the circlip before installing them, even though I've been working on two-stroke engines for many years. Thank you, I'll be more careful in the future!

solid advice from a Aussie in Perth

I am racing motorized bikes and a fellow competitor had the ear broken off. So I cut them off and cut a groove in the piston to be on te safe side for my last race engine.
Greay videos, but I like to see your face . It makes it more personal.

Good tip, I have not seen any other videos explain this with as much detail? The younger generation should watch this?

This was the best video I've seen on the G-clip. The 66cc engine gains power with porting as I have learned. Experimenting the Rookie way., I try to sneak up on how far is too far when opening the ports. Tearing top ends up just on this topic .

[cgriebel]

Thanks for the pro tip. I've never looked for this and sometimes it's the small oversights that can ruin a job.

I fitted some yesterday and I was lucky, I noticed the bend in the ring and faced it outward, I thought it was like that to make it easier to fit.

[timdryden]

An excellent point, I never considered this, and was unaware of the radius's function. THANKS

This is very helpful and I wish I seen it sooner. Last year I bought one of these engines from bike berry and I was new to this so when I installed it I pushed the bent pin in. Basically around 3 months later i went to start up my engine and when I dumped the clutch my bike wheel skirted against the ground, and upon inspecting it my piston clip was gone. I tried 3 different times to fix it and i eventually gave up and scraped it. Currently I’m gettin a new kit and the engine will be assembled already so I won’t have to worry about that happening again.

Thank god I saw this now, I'm will swap my cylinder and piston soon, and I had no idea about this tiny important detail 😮 thanks for making an actual educating video😁

[outbackenduro]

Thanks for this in depth video. Isn't it amazing what detail can do for your outcome. In this case the difference between a disaster outcome and one of many trouble free hours.

[louiemilton]

I thank you very much for this interesting fact bet I been fitting them wrong way for years. Thanks mate top bloke

Awesome advice - I've stripped an engine and found the ears close to breaking off. I now always remove the ears from the clips if they happen to be there.

EXCELENT VIDEO, EXCELENT EXPLANATION, GREAT, GREAT, I was a victim of that specific damadge in my 52cc engine. The machine had problems 6 months after purchase. That clip was installed from factory and when I dissasembled the engine, liittle part of that ear of clip broke and scratched all cylinder and piston. Fortunatlely I saw this video before reasembly all. Thanks...

Thanks very much AuMechanic. I'm looking at buying and rebuilding an outboard motor, so really good to know about this.
