My model 400 has a slightly different timing on the rotation of the one track to the other. It is just the way the front axle was made. If you have original cotton fiber reinforce belting, that tended to shrink over time especially as it dried out from being wet. That might account for the mis-fit i...

I believe the L252s are a 25mm taper with a key. There are some model 700's that have the 25mm tapper, I am running one on my 400. If you are looking for a model 500 fixed sheave, I might be able to come up with one for you. I will have to look through my parts supply.

Also the Fairbanks primary clutch was not designed for a 2 stroke engine. It was not rated for the RPM's possible for the L152. If someone revved up he motor without a belt on or if the belt broke during operation, the engine would over rev and achieve RPM that exceeded the limits of the clutch. Thu...

You have to keep in mind that many of the updates than eventually made up a factory issued 200A were applied to the model 200's at the dealer and owner level. See my write-up under Hus-ski Information, model 200A. Ken M.

The bolt in guides are the same ones installed on the 200/200A/400 Hus-ski. They just have an "L" bracket welded to them to allow them to be bolted in rather than welded in as I did not want to wreck the paint on a restored 444. It corrects the issue where the unsupported top track sag caused the tr...

I have at times seen discussions regarding the track slapping the bottom side of the fenders on the Hus-ski 444. Some have raised the engine compartment and fender from the under carriage to provide more clearance. The real problem with the model 444 is they did not install the upper track guides th...

Hello all, here is my two cents worth. Most piston failures are caused by lean running, not the ratio of oil. Now saying that, there is a minimum amount of oil required to protect the engine. I run almost all of my 2 stroke engines at 40:1. But, I choose a high quality oil. I will never run oil pack...

Barrie, I did not know that. My 400 does not have it, but I believe my lower chassis is from a 200/200A. I will be re-restoring my 400 some day soon, that would be a good addition to help support the fender. Ken M.
