More Air Drain Isuses

I would really love to bring "Boss Hawg" down but Don't know if I will have the bugs ironed out enough to bring it down the mountain,and don't know at this late stage if they even have spaces left .If not ,may just drive down in the Suzuki one day.

I am a lot more cautious going down the hills than up.Jake brakes on these two cycle engine's are useless!!!

My Jakes seem to do a pretty good job on my 91 silver 8V92TA. Maybe your engine is worn out. Think you gotta have a little compression to work.

Determining the efficiency of any particular Jake install needs more information.

Under what speed, what gear, what RPM, are they not working well?

Jakes of all types need high RPM to work their best.

Jakes need to be properly set, using fine measurements, same as the rest of the overhead.

A Jake won't do much at 50 mph in top gear no matter what drive train is involved.

There can be troublesome places, there are combinations of slope and speed that won't match your available gears and Jake strength for a smooth descent. With a little practice, you will discover which variable to adjust to get it all balanced.

Even in the newest coaches, the driver is choosing the gear and speed to match the available Jake strength, 3 stage Jakes complicate things further!

There's more to it than just flicking the switch.

happy coaching!

Jakes on a 2 stroke you need to be in 3rd down to have much affect,when I changed from 3:73 to 3:36 gears it was like not having any Jakes in 4th gear,you have to keep the rpm up the 2 strokes are a little weak on oil pressure at low rpm for Jakes to work good
