Just done YZ timing

The power has sure changed and it seems to rev out much quicker but feels a little stifled up in the top end. I think it needs to breath a little better
to of all of you who have done this, did you change your jetting?
what sort of pipe do you have?

it appears to have spotwelds in it right down 3 sides of it and i assume they hold what baffles etc are inside. i did consider getting a mate who is very good with mig and grinder to look inside to see if there was any tricks we could do,has anyone opened one up ? that little inch hole just doesn't seem enough, especially when you see most aftermarket pipes.
am currently looking at Australian made Staintune pipe here is link.

I don't know of anyone who has tried to modify it, but I saw a similar thread a week or two ago with an '05 pipe, I think he was an Aussie too. Do a search for that and see what you think.

That pipe is different from the US models, looks exactly like the stock pipe that came with my Canadian model -
Yeah, this is the canadian model This thing is heavy as hell and way too much corked up. I would say the stock YZ pipe is a good deal. I've compared it to the FMF PCIV and I'd say the PCIV is much more noisy and I'm not sure any better than the YZ pipe... The PC4 sound is great though
I still have to try the quiet insert on that PC4 and see how it goes. I know of many TT members who think it's the way to fly... I'll see.
Oh and by the way, my bike is YZ timed with a WR needle and I do seem to have a little bug that might come from the needle according to JD so I might try the YZ needle (did not even know the needle from a YZ was different until Hamish's post).
