Will Bent Head Pipe Affect Radiator

Had a slide out and bent my head pipe a little bit on an '06 yz450f. Aside from a little airflow constriction do I need to worry that the heat will affect the bottom of the radiator. It is now about 3/4 of an inch from bottom of radiator.

Plan on sending it out to get repaired but need to use it to race on Saturday and there is not enough time.


3/4" is a lot of room compared to most older 450's. It's a non-issue. No worries.

If you are concerned about it, let it idle for a couple minutes and get red hot, then push down on the header with your boot. It will bend back down. I have done this a couple of times. My header now needs a pro fix but it did bend back.

better yet use a pry bar and block of wood , u might melt your boot.

You may be able to get a new stock one from a fellow TTer for a good deal. I went that rout and was very happy with it.
