Am finally tearing the TRV apart to snorkel it and do some other performance mods.

I certainly know not to decrease the diameter of the air intake, but an wondering if the intake and exhaust for the transmission need to be such a large diameter (in other words, does the tranny move so much air through it that the snorkels can't be smaller?)

any thoughts from anyone with experience installing a snorkle on a 650 H1 or TRV 650 H1?

 

I was able to answer this question by looking at the Mudpro itself....

YES, you can run smaller diameter transmission intake and exhaust tubes.
