jets

[wutangbuzz]

I've stuck a race can on my fazer which makes it sound much more fun but its made a big flat spot early in the revs. Anyone know what jets I can use to get rid of this?

In a single word: no.

It's a bit trial and error, but jets are cheap. Might be a ball ache to do though, buying some, fitting, repeat. I'm surprised it's caused a flat spot though - have you changed the air filter too? And have the carbs been balanced? My tail can breathes VERY freely, and I have a K&N fitted. I've debated doing the jets too, see this thread for some idea's, although remember - he has cone filters fitted:

You breath out of a tail? I'd check that everything else is 100% before going down the rejetting route. I'd also stick the original exhaust back on and see if the problem does actually go away so you know for sure it's the exhaust causing it

I had my bike rejetted, it simply didn't work, and had it put back to stock because it just didn't feel right.
It was Dyno'd at the time so no guess work either.

It's like talking out your arse, but more subtle


Replace 'breathe' with 'flow' if you're feeling pedantic. As His Dudeness said, I'd keep rejetting as a bit of a last resort.
