Rejetting required ? Need help. :)

[Pablo]

I purchased a Yoshimura slip on pipe, and I don't know if re-jetting is required.
In the case that it is, I won't do it myself but a friend who will do it for me asked me if I knew what is the stock jet size for a '05 Kat 750.

Does anyone here know?

Thanks!

you don't need to re jet for just a slip on, only if you go with a full exhaust then you need to jet.

yep, you don't need to jet, don't worry about it.

Thank you both!
