Yikes !!! Siezed, chunks out of throttle plate
Posted October 06, 2003 - 09:14 PM
Anyone siezed up like this? I have read a couple posts where the chunks go through without damage and Brandon said he found a piece inside of his. I have not read any posts that mention bieng siezed.
If anyone can give me some info on what to expect I would appreciate it.

Did you remove the throttle stop on your carb completely as I understood this was a likely outcome from not just grinding it down or repalcing with the YZ one ?

I would still like to here from anyone who has had an engine siezure as a result of a broken throttle plate.

Here's the latest:
I pulled the carb and yes the bottom right side of the plate is gone. So I put a wrench on the fly wheel nut to check and see if it would turn backwards and
So I took it to the bottom and beat on the cylinder with a plastic mallet. It still wouldn't go past TDC so I turned it until the intake valves were open and blasted air through each valve (while using the hammer!), I also blew through the exhaust while pulling the decomp. Same with the plug hole. Yeehah, I could go past TDC.
So I kicked it through easy while listening closely and I saw something fly out of the plug hole. Couldn't find it on my (dirty) garage floor, so I kicked a little harder. I heard something small bounce off the wall a couple times while kicking it over more. I never felt any resistance while doing this.
I'm going to fix the carb and ride it!

You won't see my bike there though.

I'll be sure and let everyone know how it goes.
I wonder if GrahamO and Rockieman ride with their teddy bears?

I was just cracking up at: So I took it to the bottom and beat on the cylinder with a plastic mallet. It still wouldn't go past TDC so I turned it until the intake valves were open and blasted air through each valve (while using the hammer!)
I just love the thought of beating on my cylinder and kicking it over with metal chunks in the cylinder... LOVE IT!.
I do know a guy who rides with a teddy bear... rides very fast with a teddy bear.

I got the new carb slider installed and now it runs better than ever. I think the slide had been developing the crack for a while and it had been throwing off the jetting and causing it to run a bit rough. It also looks like Yamaha re-engineered that piece to make it stronger (machined vs. pressed.)

She runs great!
I've got 50+ miles since, and all is well. I found that I do not have a throttle stop, I think that was probably the root cause.
I've read a lot about the length of the stop, does anyone know the thread pitch/dia?
All is well that ends well.
