Hrc carb tray help

Post by fatkid_loves_cake »

Hey folks
I have a question for people who are using carb trays on there road bikes, what sort of mods have you done to the carbs and air setup to get them running as best as possible?
I realise this has probably been done to death but not really found much via the search
and I know airflow is a big issue on these bikes just wondered if many people still used them and got a nice clean rev range with them

Cheers zeb
when u say .5 washer do you an extra washer or the standard orignal one
did you try running it with the standard airbox lid or have you always had the tyga one

I have the air tray on both my bikes - all it does, really, is keep the carbs cool. it is not ram air or anything like that.

All flaps in place too..

there are a lot of different opinions around when it comes to airflow.
I modified the airbox and have no rubber flaps and it works :grin:
