Re: I did it! I cut my muffler off and added a new one.

Were you able to see little markings on the jet that noted the size? It would have been chiseled on there "128" or something along those lines.

Even if they didn't actually bore it out to a 130, that shouldn't really matter. A 128 is pretty close.
Take it for a full speed run and see if it feels laggy or if it seems to pull a little better. You'll still probably want to raise the needle just to be safe. These things are already slightly lean from the factory.

The other stuff that I mentioned, jetting theory, still apply.

PM if you need more help with this. Send me photos of what you got or something and I can walk you through this stuff. It can be a pain in the ass getting it right. But once it's set, you can leave it alone forever.

Yeah, the jet he gave me and supposedly opened to 130 had a printed 128 on it. My concern is the hot motor and smell of hot oil. I will take it for a ride maybe saturday. Heat wave coming tomorrow and thursday and i dont ride in that dangerous heat..

I'm assuming you've checked the usual things, like oil level.

How many rides have you taken the bike on since you put the muffler on there. Is it few enough that you're just now starting to smell the familiar scent of the metal going through it's heat cycles and burning off some of the imperfections? That's not uncommon for a new exhaust.

I put about 75 miles on with the new muffler.

That's enough then to have already been through the first real full heat cycle, assuming you put on more than 1 mile at a time.

Well, it is not illegal to change a muffler from stock, it is illegal to change it to another muffler that does not meet the original EPA specs as the stock muffler.

Wow, you have only put 75 miles on your bike since May 8th? Do you have another bike that you are putting all the miles on? Oh I forgot that you are a New Yorker :roll:
