Hi guys getting to the point where my race bike is nearly ready to put on a dyno but quick question do I need the hrc copy Airtray on for the dyno run or can I get it done without as it will make it easier to play around with the jetting if it off !!
Thanks

Without it the airflow to the carbs will be different.
So you may well need to get it done twice.

I have a fiberglass HRC tray for sale if you need one

I reckon it does more of a job shielding the carbs from the heat than any kind of ram air bollocks.

dyno run without it will be no worries I reckon

It should be fine to set it up without it fitted as long as its just the tray. We set the RC30's up the same to make it easier.
