Hey folks this is too good not to share, and I haven’t read much on it so her we are.
Backstory: had a red pipe, ran awesome. Came loose/ blew gaskets 3 times in 8hrs. Went back to stock pipe + the list below got me very impressed in a hobby where more power is never enough.
Current setup:
- Ported (yamanube templates)
- Exhaust sleeve for stock exhaust. Not sure how much of a difference this makes but I had it so I put it in.
- Back flush fitting on stock pipe to pisser (has a smaller hole (3/16ish?) to dump less water, better for reliability imo, while maintaining visual ref of the pisser)
-h.s.i. Thin head gasket
Jetting: Single 44 Mikuni, 120/145, 95g spring, 1.5t out low, 1-5/8 out high. Impeller/ electrical stock. Pic of plugs below.
This setup has 75% of the power of what I had with the red pipe. I didn’t think it was possible with the stock exhaust that has an extremely uneventful-non-existent powerband.
It is somewhat snappy with a legitimate powerband that gives that “on the pipe” pull right around 1/3 throttle.
I think most people going through the hassle of porting probably want or have a pipe already, but if not. I would recommend the ported/ stock pipe combo and see how you like it.
So there you go, ~$150 and a few hours with your Dremel gets you some brap plus the satisfaction of having more than just bolt on power.
