Oh ohh.... Combustion chamber fishing?????

So I get to the second to last shim for my valve adjustment, and the cheapo wire tie, tie wrap, zip tie thingy I was using broke off the tip (about 3/8") in the spark plug hole. Can anybody tell me whats the best way to get it out or if I even need to. I'm gonna wait for you guys before I even look at the bike again. Thanks.

 

Use a small tipped vacuum. Is the tip in the chamber or in the intake/exhaust of the valve you are working on?

 

I cant see it but as you know that's a small hole to look through. But I rotated the cams several times before I realized it was missing. So I don't know if its still there or worked itself somewhere else. Im not very knowledgeable about the inner workings. I try and rig something with my mini shop vac. Which is worse out of curiosity, valve or chamber?

 

I doubt it "worked itself" anywhere else. Most probably just bouncing around on top of the piston.

 

If it's the PLASTIC tip, I wouldn't worry about it too much...it'll burn up real quick.

 

Unless it gets caught under a valve head when the piston is on its way up...

 

Might pay to drop exhaust, bigger hole to look in or poke shop vac into?

 

turn it over a few times with the plug out will probably blow out of the spark plug hole. Not saying it won't get stuck in a valve think i would take a chance before pulling the head

 

Yeah, turn it upside down like a piggy bank and give it a good shake, it will go out eventually, lol!

 

:}) I think I better get back in the gym before I try that. I tried the vacuum with the hose through the spark plug holes, then I tried to pull the exhaust but I couldn't get the bottom part to break free, so then I pull the carburetor out to look in that way, but I couldn't see anything. Pulled off the intake boots off to get a little better look also, which I needed to pull them anyway because theyre cracked and whoever installed them had the seal blocking part of the passage on one of them. Any tips for the stuck bottom part of the exhaust before I through the bike on my shoulder upside down and start jumping up and down?

 

Wire wrapped with fly paper through plug hole...call me crazy!

 

2 Q-Tips taped together.
Q-Tips taped to Coat Hanger Wire.
Dip Q-Tip ends in High-Tack Spray-a-Gasket.
Let get tacky.
Jack Piston to height for "Good fishing".
Good luck!

 

Absolute Genius right there!

 

Roll the engine until both valves are closed and shoot compressed air through the plug hole. It should come out.

 

As Rick would say...choose any prize of the top shelf! :idea:

 

cool. thanks mlew. That'll give me something else to try tomorrow after work. I did finally get the exhaust off and I cant see anything in there. I tried fishing for it with the hanger with a bunch of inverted duct tape zip tied to a small loop I made (I didn't have any fly paper......or spray a gasket). So now with carbs boots and exhaust off I'd imagine I should see it blow out somewhere. Thanks.


LOL...... you guys may not understand if you've never seen the show, but you guys could make the challenges for that show Minute to Win It. : )

 

when i helicoiled my spark plug hole... i used cotton rope soaked in motorcycle oil. Try something similar with spray adhesive maybe?

or try one of these. I use this often (my fat fingers drop small screws into small spaces constantly.

thanks guys for all the help, hopefully when I get off work I can get out. My next question is, now that I have my clearances in check, and i get everything back together, I planning to sync my carbs with a home-made synchronizer. I have my mason jars and Im planning to buy the necessary hoses when I get off work. Does anyone know what size hose fits on those vacuum (no sure what theyre called but on top of intake boots)?

 

Be very carefully at this point you are risking a bent valve.
Nylon in wire ties is very, very tough.

Do all movement slow and with the other plugs out. Cover them with a rag. Any sudden resistance means STOP and find out why.

You must fish it out and Know you got it out.

I have been down this road. Your only port hole to see is the plug hole , so don't waste time with the exhaust that needs penetrating oil and a torch.

And don't roll the engine so fast it gets smashed into the head or piston. It will do your crank or bearings no good.

Tilt the engine to one side to narrow the playing field. Then sticky or suck it out. Or take off the head.

They are called vacuum ports. The drawing I referred to to make my own sync tool says 1/4 inch interior diameter vinyl hose.
