SRS engine packages are tuned to give their best performance at the temperatures and track conditions they will actually encounter. An engine can be tuned to make an impressive dyno “trophy pull” for bragging rights by running the engine at less than operating temperature on a cool dry day.

Diaphragm Carb Operation PDF Print E-mail

 

The diaphragm carbs used on most kart engines have been adapted from power tools such as chainsaws. The usual mixture needle settings for power tools give a relatively constant fuel mixture curve throughout the rpm range from idle to peak rpm. This provides a stable idle, smooth part throttle operation and a limit to peak rpm.

Maxima 927, Burris Blend, Amsoil Dominator, Redline Kart Racing oil mixed @ 6-9 oz per gallon of fuel give excellent lubrication, low deposit formation, and eliminate ring sticking. Consult specific engine instruction pages for details.
 
Carbon Build-Up PDF Print E-mail
Just .002” of carbon buildup on the piston top is 0.1cc. Be sure to remove the head and clean any deposits from the combustion chamber and piston top before any race after which the head cc’s will be tech’ed.
 
Air Pockets PDF Print E-mail
If air pockets are left in the system, water may not circulate and the engine will overheat. If your racing and/or track rules permit, use Redline Water Wetter in the cooling system to prevent corrosion.
 
Richer Jet PDF Print E-mail
Always start rich and lean the jet until maximum performance is reached. Never run leaner than the maximum performance jet size. The maximum performance jet size will vary with weather conditions. If two jet sizes run the same, always revert to the richer jet.

Octane PDF Print E-mail
Increasing the octane level does not gain a performance advantage in the S3 spec Hondas, but prevents engine damage from detonation.  Preventing the engine damage from detonation by increasing the octane level of the fuel will keep the current performance level, but reduce the spec Hondas' top end maintenance cost without changing the engine rules.
