BOOM TRIKES V2 Automatic - Automatic Gearbox Operation; Frame, Forks, and Suspension Adjustment

2.6 AUTOMATIC GEARBOX
The V2 is equipped with a CVT automatic gearbox.
A) Automatically transmission
To ensure the most comfortable ride possible the vehicle is equipped with an automatic gearbox, a
centrifugal clutch and electronic engine management. This system was developed to obtain best
possible acceleration and lowest possible fuel consumption both on even roads and up hills. If you stop
the vehicle when travelling up a hill, e.g. at traffic lights or in a line of traffic, use only the brakes to keep
the vehicle from rolling away. Do not open the throttle, instead let the engine idle.
If you use the engine to stop the vehicle from rolling backwards, due to excessive
friction this can cause the clutch to overheat.
Avoid clutch friction over long periods. Other than in the situation described above, this can
occur when on full throttle up steep hills, or when moving off on a steep hill with a passenger
and luggage.
In the event of the clutch overheating observe the following precautions:
1. Do not ride the vehicle under these conditions over a long period.
2. If the clutch overheats, then let the engine idle in neutral for a few minutes to allow the clutch to cool
down.
2.7 FRAME, FRONT FORK, REAR DAMPERS, REAR AXLE
A) Front fork (maintenance-free)
b) Teleskopic fork
Front suspension is by a hydraulically operated telescopic fork. If the fork seals are no longer oiltight,
then take the trike to a specialist dealer to carry out repairs. As the front fork is a safety-relevant part, if
problems occur we urgently recommend that you contact your specialist. The front fork is a non-
adjustable unit.
Each fork leg contains 270 c.c. of SAE 10W fork oil, which should be changed every 3 years.
B) Rear dampers
Fig. 5 13
The standard spring pre-load on the
rear dampers offers an optimum
compromise for riding either on your
own or with a passenger, and in
both of these cases no further
adjustment is required.
However, if most of the time the trike
carries a passenger and large
amounts of luggage, then adjust the
pre-load to a higher setting.
