Hello everyone I'm a new member. I've often came to this site for help.
All these posts and discussions are very helpful to me. I do have some experience and knowledge so maybe I can also help someone else out there. . Here's my question. I have 04 YFZ 450. It is all factory . The exhaust glows red when warm. Should I put bigger jets in the carb??
Also it has no baffle in the stock muffler . Is this GOOD. OR BAD ??
.
I did wrap the exhaust header with header wrap...

 

Welcome to the forums.

This happens a lot more than most people think. Check out the Yamaha section for the answers to this.

 

Thanks for the reply. I'm still learning my way around this site. I'm going to look there. Thanks
