Mini-Quad Power-Up Kit
General Information
FITS MOST CVT MINI QUADS
-Your Exhaust Kit Should Include-
Hetrick Racing Exhaust System
Rear Torsion Clutch Spring
Rear Clutch Shoe Spring Kit
Front Variator Weights
Approximate Main Jet
Air Box Vents (If Necessary)
This performance kit was designed to work
perfectly on a Kasea Skyhawk machine. There is a chance you may
encounter problems within the installation of this kit but it is
unlikely. The exhaust will work on most CVT style mini-quads engines
(except LT80 style). Minor modifications to the chassis/body to mount
the exhaust are not uncommon. Common modifications are (but not limited
to)…
·Removal of Oil Injection System
…To clear way for the exhaust expansion chamber. This is a
common practice in racing situations because of the O.I.S.’s tendency to
malfunction & its inconsistent oil/gasoline mixture. The solution to
this problem is to remove the O.I.S. and mix your gasoline with quality
2-stroke oil such as Bel-Ray H1R or Klotz R50. We also recommend 32:1
mixture.
·Removal of Battery & Box
…To clear way for the exhaust expansion chamber. This is a
common practice in racing situations because of the added weight created
by the electric start system. These quads come with a back-up kick
start anyway.
·Silencer Mounting Bracket
…To relocate rear silencer mount.
Use a piece of flat stock metal to drop mounting location down
approximately 2”. Necessary only if above fixes do not solve problem.
·Cut up to 1.5” Off of Head Pipe
On some machines it may be necessary to clear floorboards or
other parts that may get in the way. It is a good idea to cut in
1/4" or 1/2" increments.
_______________________________________________
We recommend use of the
spring with the thickest diameter wire, typically “Red” in color. The
thicker the wire, the higher the stall speed.
”Stall Speed” – Simply, the amount of engine RPM at the
point where the clutch engages.
If you experience a lack of acceleration
you may have a stall speed problem.
For added stall speed we recommend the following-
· Drill up to five 3/16 holes into the
side of each shoe.
· Drill up to five 11/32 holes into the
side of each shoe, outside of spring.
Do not drill the entire way through
shoe. Depth depends on the amount of mass you would like to remove.
Start with less depth and fewer holes to assure you do not remove too
much weight. Take your time; drill only a few holes at a time. It may
require up to five of each hole per shoe. Any questions give us a call!
On the back of this pamphlet you will find a breakdown of a general CVT
setup.
Yours may be slightly different but keep in mind this is a generic
diagram.
