Title: Shorty PG has started hitting very hard when put into reverse
Post by: Jaychalmers on January 15, 2018, 04:57:43 AM

Any thoughts as to why my shorty PG (with stock case, brake, and aftermarket race internal parts), and which still runs great in both forward gears, has started to hit very hard when put into reverse, even though idle has not been increased?
Thanks.

Could be a couple of things, first thing is to check pressure at the reverse port. If its exceedingly High, something above 230psi it is possible the boost valve is stuck. If the pressure is normal then I would suspect a spring issue on the piston. I just did a glide a couple weeks back where the springs were laid over like Domino's.
