Broken E-clip on Needle
« on: October 03, 2024, 08:38:33 AM »
Well, I had read about this happening to some people recently...and I wondered how could that even happen! Well I go for a ride this past weekend and out of the blue my bike just dies!!!

It wouldn't start back up unless I had the choke on.....it would idle....but as soon as you tried to move it would die.

Towed it back to the truck...loaded up and off to the home shop.

I thought at first it was a clogged Pilot jet....but it was fine.....then I saw the needle in the Nozzle of the carb and NOT attached to the slide!!!! DOH!  ???

Here's a pic of what was left of the E-clip..... Just glad it didn't make it's way into the Engine.

Bizarre. I have never even heard of this until recently. Maybe there is different thickness or materials being used for the clips?

It looks like a lot of the clip is gone. It wouldn't hurt to put a bore scope down the sparkplug hole and check the piston and cylinder. Glad it was a cheap and easy fix for you.

Best regards

Jason - The good thing is the cable holder is screwed into slide so it contained all the shards of metal.....no chance of it entering the engine....but yeah it is weird.....makes ya wonder what they're making the e-clips out of these days.....for it to break apart like that....must have been too brittle.... ;)

i never heard of this either, but in 2022 race season it happened to a competitor on 2 different races.  Then around middle of 2023 race season it happened to me.  Near as i can tell the clip evaporated lol.  i've been riding/racing these for 30 years prior without this happening

Wow this is very odd. Never heard of this ever happening.

John was this clip the original to the carb? Or did you replace the original clip at some point?

Not sure if the Clip was the Original.....I believe it was on the Needle when I decided to change from a DGH to a DGM....to clear out an off throttle blubber....I really made it responsive after that.....so whatever that needle had on is is the culprit.....pretty sure it was a KEIHIN clip.
