Installation in a HPI BAJA

Installation in the vehicle is straightforward. The engine is designed to make use of most of the existing mounting points
with the exception of the left side of the chassis. Here two brackets are supplied as part of the engine package, which
replace the original parts. 

Some adjustment will be required to your throttle linkage to connect to the carburettor due to the size and spacing.

The RCMAX exhaust mounts to the engine with a sealed joint and to the chassis via the supplied brackets
and rubber support mounts. Thus it is quick and easy to release if you need access to your radio gear, etc.
It is recommended that you fit a 

Team Chase

 roll cage to your vehicle to protect the engine and expansion

chamber in the event of a roll. 

Left side front mount

Left side rear mount

Right side mounting bolts (2 behind pinion)

: See supplementary sheet for installation in the Losi 5ive-T

Due to the considerable increase in power over the standard engine it is advisable to replace the standard
drivetrain parts, such as gears and drive shafts, with heavy duty, upgrade parts. We would recommend 
using a billet aluminium alloy diff case with steel gears throughout. Blackbone Racing now make a full set
of replacement, heavy duty gears for the Baja gearbox. 

Primary drive gears should only be from Blackbone Racing, which we stock a full range of sizes. We would 
recommend using 26/48 or 27/47 gears with your 65cc engine depending on taste.

Drive shafts should be heavy duty types. We would also recommend  that you fit a locked or limited slip differential.

To make control of the vehicle easier it would be advisable to fit some sort of wheelie bar on the
rear of the chassis. This, together with heavy oil in the diff (250-2M), helps to make the vehicle more driveable
on the throttle. The ideal solution is the RCMAX HEX-LOCK KIT to forget diff failures for good!

Finally a good set of wheels, preferably BRP wheels will be required to prevent constant foam blow outs!
