13.5:1 and Hotcams

I am going to install a JE 13.5:1 piston and Hotcams in my 08 YZ450F which is being used for supermoto. Got a package deal I just couldn't pass up.

Just want to check with the collective to make sure I'm not going to run into any piston / valve interference issues or anything else I should be concerned about.

Anyone install this combo? Impressions?

Thanks in advance, John

only issue i can think of is all the $$$$$$$ your gona spend on raceing fuel

There shouldn't be any interference problems, and depending on your elevation 93 pump gas should be fine to run in it.

There won't be any clearance issues.

Let us know how it turns out! :thumbsup:

Also, update the jetting database if you change that to help others who want to mod.

Many people run 13.5:1 without race gas. You may have to run it if your at sea level from what I understand.
