Need help with triple pipe
I have the above referenced.
Last weekend it was running fine, until I stopped. When I went to leave it would not rev above 4500 rpms. I drove it home with no heat in the pipes or the cylinders.
Tonight I replaced the plugs and it reved up higher on the hose than it did the other day. I let the motor warm up on the hose and hamered it for enough time for it to rev up to 7800 rpms.
While running it on the hose I noticed one of the pipes where they mount to the manifold was moving in and out as I reved it up. Only one of the three was moving in and out. I know that springs hold those pipes in and
there was oil on the pipe where it was leaking.
My question is , could that pipe moving in and out foul a spark plug?
Do I need to replace the springs to stop the pipe from moving in and out?
Thank you in advance.

You got the two springs and the 3 orings on each pipe. Make
sure your brackets are tight on each pipe too. Could be a foul
plug, or even ignition.

Are you saying you put three o rings in EACH pipe?

im sure u looked already...
make sure one of the bolts that holds the bracket for the spring didnt walk...that pipe should not move. if all else looks ok (mount on pipe also) get a set of new springs.
i would pull the pipe and check your kevlar seals and o-rings now. probability would be that the kevlar got blown out from the pipe moving. the change in exhaust pulse probably fouled a plug.
pressure check the pipe while your at it.
compression check out?
if the above checks out i would look at a few other things before pointing to an ignition issue.

Compression is fine. I will check the mounts and brackets. I am surprised
I found the pipe moving. I am getting better. I think I only have one ring
in my pipes, which explains why they seep exhaust all the time.
My single is ready after crank let go. My triple is going to get covered,
and put on a stand after I fix.

Hop is 100% correct again, check the kevlar packing cords, mine only lasted 50 hours.
I have had good results using ultra gray permatex to lubricate and seal the o-rings.
Make sure to let it dry for at least 4 hours prior to running it. Ultra gray stopped all the oil spitting blowby from the flange pipes for me.

Did you HEAR any exhaust noise inside?
Sounds to me like you lost a reed, or have a cracked pipe...or more than one item.

Hope it was just a fouled plug not running on all the cyl.. Mark you can go by a miller bearing if you have one up your way bring in the o-ring they will match it up and they come in a package of 5 for a whole lot less money. You will have to get the kevlar o-ring from riva though. If you are going to order the kevlar just order the heavy duty springs also they work a whole lot better
