Don’t leave unburned fuel inside the engine
for long periods of time. The nitromethane
of the fuel can promote corrosion of internal
parts.
MAINTENANCE
Lack of engine maintenance will lead to
premature wear and engine failure.
Racing engines are very precise machines. Correct use and
maintenance are essentials for a long life.
Our Warranty doesn’t cover malfunctions or failures due to
improper maintenance
Racing engines reach 40,000 RPM, therefore the stresses on
the moving parts are extreme.
We suggest that you regularly check and verify the following:
•
The wear of the crankshaft and the play between the
conrod bushing and the crankshaft pin;
•
If the compression is adequate.
Compare these characteristics with the ones of a brand new
engine after break-in. If you have doubts on how to evaluate
the results, ask your retailer for hints and suggestions.
Mechanical problems are often caused by:
•
Poor fuel quality
•
Improperly maintained or installed air filter
•
Excessive wear of moving parts
Each of the above points requires regular checking and
maintenance.
When using the engine in racing conditions, we recommend
that you replace the following every 5 litres of fuel:
•
The conrod, as it’s one of the most stressed parts in
the engine
•
The ball bearings, as they are highly delicate
To replace the parts, ask an experienced user with proper
tools and skills, or ask your retailer.
