What petcock to run?

[highland]

I am in the process of putting a bigger carb on a trx 90. What do you use for a fuel petcock? Also this bike is for trail riding will the stock air box work,flow enough? It is a big bore 114, 26mm carb. Thanks

I just finished 114 kit on my 08 trx 90. With strater motor. Most guys mount carby forward so u can use the CRF80 fuel tap.
I still run my 26mm mikuni carb rearwards. but i made a plate and tapped a hole to screw in a 90 fitting and mount a aftermarket inline fuel tap.
To mount the carby i cut and edit and welded the manifold so the carby tilted just above the starter.
then run 1,3/4 silcone hose through the air box and placed a steel sleeve so i could slip the air cleaner on.

I have some pics if you need. Bit of stuffin around but over here in oz tracks get muddy and other bikes have troub with air cleaner clogging up.
