Hi i just brought a brand new 08 yz450f a couple days ago. I live in michigan and its in the 20s and my dad and my brother told me they dont think its a good idea to break in the bike in the cold temp cause they think its not good for the engine. Can you guys tell me if its true and should wait till spring or would it be allright.

Google "motottune"

Temp means almost nothing If it is 20+ degrees out, you are fine.

Don't you think the jetting will be way off? I know there bathed in oil and all, but personally, I don't like running any of my engines lean. Especially while breaking in a new engine. Maniac

When did the FI get put on these bike? I think it was 09 so yes, your engine may be lean.

+1. No worries. Tape up one rad if you think it is not heating up.

Not a problem.

Even if the bike was so lean as to barely run, no damage would ensue. This is not a air cooled two stroke. After the engine has run for five minutes, it is broken in.

Just make sure you follow the manual and change the oil pretty quick (can't remember the exact specs)

enjoy your new toy :excuseme:
