Mounting a WF to a cadet chassis?

Hi guys,

We're currently running a Comer K80 on a Top Kart cadet chassis for SCCA autocross but I'm curious how difficult it would be to mount a WF motor on this chassis instead. Doesn't look like there's a lot of talk on here about cadets. Anyone have experience mounting on a smaller chassis? Also, what is the weight of the WF motor? We have to add so much weight already because he is so small that the WF might actually work better for us since it's bound to be heavier than the K80.

Thanks, Scott

Hi Scott, It will fit if the right side seat post will allow it. You will need a slide adjustable motor mount to align everything. I have used the Burris series and have had good luck.
This is an older top kart chassis and you can see the side mount has been replaced with a post.

This is an Animal on an older CRG , it has two seat posts added to allow for seat placement.

Here is a side view of the same CRG Animal combination to give you a perspective of the motor verses driver position.

I just weighed my spare WF on a bathroom scale and its says 42 lbs with the clutch and starter. If you are not running a spec class, ditch the starter and clutch as there are a lot lighter drum clutches out there.
The seat posts I used can be bought from most on line kart shops, they probably won't have the correct diameter for your tubing size, I just bought over sized and used some alumn to make shims for the difference.
Hope this helps, it will take some work and some ingenuity but will fit.
You might want to look at using an Animal instead if you can as it comes without the clutch and starter, plus I think you will find the bottom end is better that the WF. There are some good cams out there for the Animal, but a word of caution if you go with some aftermarket cams that don't have the easy start , you will need to get a starter nut and use your hand held to fire the motor. Those little motors can really hurt your hand when you are not expecting it.

I just mounted a clone to a Top Kart cadet using a BMI mount offset to right by one hole. The clutch just clears the seat after I bent the mounts a tad. The chain runs nicely to the side of the third bearing rail. If I had to reverse the clutch it might hit the seat mount. I bought a clamp on seat post just in case. I can email pics if needed.

Might work, if the seat has enough space to be placed to the left a bit. the second issue is, as has been mentioned, the motor mount. A flat-style adjustable one will do the best. The alternate seat strut setups using the frame-tubing clamp style can be made to work on almost any setup. I needed a longer strut than was available, so I fashioned one out of an old bumper. Can get a picture if needed.

An alternative is to get a full-sized chassis and set it up for a smaller driver to grow into.

For SCCA, the WF is the only legal OHV Briggs. Starter and standard clutch must be part of the package.

Just did this very thing on a Birel cadet. Had to put the drive sprocket out board of the clutch, and had to bend the seat brace quite a bit to go around the chain and clear the cylinder head.
Burris 2 piece mount made it all possible.

Now to mount 60 pounds of lead Rolling Eyes
