Rev limiter question
Has anybody bypassed the governor and put a rev limiter on a Koehler 27 EFI to get more rpm’s? Just wondering if it would work with it being an EFI motor.

Re: Rev limiter question
Just adjust it to spin more. It'll turn up beyond 4400 if I remember correctly. Do some searching on the forum. It's probably been 3 or 4 years, but it's been discussed here at length.

Re: Rev limiter question
I have the 26.5 Kohler EFI. That may be what you were referring to. I bought a longer screw to put more tension on the governor spring so it would kick in at higher RPM. The coils on the 26.5 have a built in 4500 RPM limit. I think we discussed this in the longtail forum. I regularily run my backwater longtail at 4200 rpm. I am no authority though by any means. Good luck.

Re: Rev limiter question
Pretty sure you were one of the conversations, and i thought it was something simple like the screw. I do know those engines dont mind spinning past the stock gov setting, so thanks for helping the OP out.
