For initial starti ng, set the high speed jet (81
a t 1Y2 turn s op en, and the low speed jet (C)
at 1 turn open. Set the idle speed screw (AI
for best idle R.P.M. The high speed screw
can now be set for t op performance, this
must be don e while the vehicle is running
with driver aboard. Find the best setting and
th en open the high speed another Y.1 turn.

Remember: A lean carburetor will
cause severe engine damage.

BRA KE ADJUSTMENT
Can be made in one of three different
ways or a combination of all three ways.
Init ial setting, w hen new, should be
made at the ca liper lever (Item " A" ,
Fig. No. 4 ). Then furth er field adjust­
me nts can be made at t he handl e bar
cont rol lever by loosening th e jam nut
(Item "C", Fig. No. 6 ). Then turn ing
sleeve (Item "0'-; Fig. No.6) to tak e up
cable slack, then re-tiqht en jam nut.
Cable adjustm ent s can also be made at
t he nuts (It em " B", Fig. No. '1).
Do not adjust brak e too tigh t . After
a d j u s t ing brake make su re ca iiper
assembly does float side to side .

A. T he sh o c k absorber is installed at t he fa c to ry in the rear hole location " 3 a" . This p osit io n allo ws

B. T he mid d le hole posi t io n " 3 b" lowers the fea r of the mchine and restricts the suspens ion t ravel to
betwee n 4 to 5 inches.
C. The forward position "3c" further lowers the rear of the machine and restricts t he suspension
travel to between 3 to 4 inches. This setting is suggested for rac ing on relatively sm o o t h conditions.
FRONT SPRING TENSION
4.
(Note: Minor adjustment of this sp ring d o es no t alter the ride to a great deal but it d oe s affect the
track angle contact w it h the sn ow. I
a. Normal adjustment for average condit io ns would be approximately 2 threads exposed through nut
No.4.
b. Tighter adjust me n t of nut No.4 woul d b e for heavy loads or minimum ski pressure , a nd maximum
weight tra nsf er to rear axl e .
REAR SPR ING TENSIO N
5.
a. Normal ad just m ent for soft ride or light loads should be with approximately 11," of threads exposed
t hr o ugh nut No.5. This adjustment produces maxi m um weight transfer to the track and gives m ini­
mum ski pressure during acceleration.
b. Tight adjust ment of adjuster nut No.5 is for stiffer ride or heavy loads. This adjustment produces
mini m um w e igh t transfer to the track, and gives maximum ski pressure during acceleration.
2 .
CO M BINA T IO NS & VARIATIONS O R ADJUSTMENTS
The ma in points to remember wh e n adjusting your "Super Flexion" are as follows:
1. a. Mor e tension on front spring reduces ski pressure and increases weight transfer .
b . Less te nsion on front spring increases sk i pressure and reduces weight transfer.
2. The opposite applies to rear spring adjustment.
a. Mo re tension on rear spring increases ski pressure and reduces weight transfer.
b . Less tension on rear spring reduces ski pressure and increases weight transfer.
Remember th at " S ki Lift" is not desirable for good control and manoeuvrability, but it is ideal for
best acceleration. Wit h a little experimenting in the adjustments you will arrive at a setting that
will give y o u the "Super" Ride.
3 . Do ~ overtighten sprin gs.

5. Apply light oil around steering post bushing s and spindle shafts, and all bare surfaces of ski
assemblies.
6. Siphon gas from fuel tank and run engine until it stops. Remove spark plug and apply small amount
of oil into spark plug hole. Turn engine over a few times and replace plug.
