D722 Max rpm

Post by alexanderfoti »

Hi all

All the documentation shows the D722 as having a 3600rpm redline, however, mine only revs to 3000 rpm ( with no load on the flywheel)

I am assuming that there is another variant with a lower redline, but I cannot find it.

I am thinking that I have to modify the weights in the governor to increase the redline?

I believe that, that has to to with the speed control plate and the spring(s) attached to it.

Thanks. I shall investigate, as I believe up to a point, that control plate controls it and them after that the weights in the governor control it.

Turns out mine is the 3600 rpm variant.

Its just that 90% of travel on the governor lever gives 2800 rpm.

that extra 10% bumps it to the 3600, my throttle linkage did not allow full travel!
