Read through entire instructions before starting installation. If you can not comfortably install this
product, hire a professional mechanic to do it.
Hot Grips® can be installed on any snowmobile with 7/8" handlebars and a 12 volt electrical system capable of powering
a headlight. It must have a thumbthrottle, not a twist throttle. Some electrical systems cannot handle the power
requirements of heated grips and the headlights at the same time. If you have modified your sled's thumb-throttle to a
motorcycle twist- throttle, then you must use our Street-Bike HOT GRIPS® kit instead. The difference with the Street-
Bike
is that the twist throttle grip's inside diameter is 1.000" diameter instead of . 875" and the shape of the grips in-
board end is different, adding more inboard rubber cushioning.
To pretest the grips, use a V.O.M. and check that each Hot Grip's® resistance measures approximately 2.4 ohms.
You may temporarily wire them in series and test on a 12 volt car battery or battery charger of minimum 3 amps if you
desire.
Do not leave them unattended, and do not heat them up for more than a few minutes, because without the heat
sink effect available from the metal handelbars, they may be damaged.
PREPARATION: Remove old grips and any remaining residue on handlebar with solvent. Roughen the handlebars
with sandpaper or the edge of a steel file. This will create an aid in the epoxy bonding.
EPOXY INSTALLATION ONLY: Obtain a two-part slow-curing epoxy, such as Duro, Devcon, Borden, JB Weld,
PoxyWeld, etc. Make sure it is not the quickcure type, such as a 5-minute epoxy. We need the slow cure (6-8 hours +)
because generally these epoxies are good for service up to 250 degrees F., whereas the 5-minute quick cure type
epoxies are generally good for only 200 degrees. Do not use any other method to install. We have tested everything
else, and they don't hold up under the stress and strain, torque loads and heat that is present. (Do not use silicone
seal, crazy glue, gasket cement, weatherstrip adhesive, etc. None of them will hold reliably under severe riding condi-
tions!) Check that the grip will slide onto the handlebar without effort. It is designed to be a loose fit, to have the small
gap filled with the epoxy. If it is not a loose fit, do not force the grip on. Your handlebar diameter isn't .875" and must
be filed down until the grip fits on without excessive force. Some metric handlebars we have
seen are up to . 020"
diameter oversize. Now drill the center-end of one of the grips with a small drill, to allow the air in the handlebars to
escape as the grips are installed.
A full length pencil is helpful as a tool to spread the mixed epoxy inside the grip interior, and on the handlebar. Use a
very light coat, and push the grip on 75% and remove, then redistribute the epoxy with the pencil and remove any
excess quantity. Then install grip 100%, and again remove any excess epoxy. Be sure the grips do not interfere with
any of the handlebar controls or the thumb-throttle lever. If there is interference, use a new single-edge razor blade to
trim the grip as necessary, using care not to cut near the black lead wires that exit the grip. Allow to fully cure per the
epoxy's instructions, or you may quicken the cure by temporarily wiring the grips in "series" per the diagram below, and
wiring them to a 12v. car battery, or battery charger with a minimum of 3 amps charge rating. The epoxy will set up
firm in about 30-45 minutes. Allow grips to cool off, and test epoxy for hardness where it oozed out of the grip. Do not
twist the grip to test the epoxy as it is curing, as this will compromise and weaken it.
SWITCH AND RESISTOR: The switch can be located at any convenient practical location for your left hand that
doesn't interfere with safe vehicle operation.
Drill 1/2” hole to install switch. The ceramic resistor may be remotely
