I need help I have a completely stock yfz 450 and the pipe when riding is turning bright orange is this normal ????

 

Did he tell you to check the oil???

You probably never need to do that either! DUH

Wow, what a bunch of strange posts.

Captain Carl. . . Dude. . . W R O N G

Two guys saying don't bother re-jetting with modifications??? WTF

If you do have a failure, it is probably Yamaha's fault!

 

technically you don't have to. But if you don't you won't get the performance that the pipe is there for. But it depends how far off your jets are.

 

raptorchick, lol can you start your bike too, jk.[img]i/expressions/face-icon-small-wink.gif[/img]

 

I rejet to temp's night or day, hot or cold, lean is mean.

 

Jet up!

I've seen a YFZ that was just brought home do the same thing. I know the exhaust of that engine is always hot but, if your head-pipe is that hot your valves are that hot too [img]i/expressions/face-icon-small-blush.gif[/img]

Go one larger jet size and see what it does. As long as the performance is still there you you are now running safer.

 

while riding hard it might be normal to have a orange pipe, I know it is on the honda 450 4X4's.

If you are below sea level you might not have to re-jet[img]i/expressions/face-icon-small-wink.gif[/img]
