Break-in procedures for Ultima® Engines
Follow these guidelines closely or you may void your warranty.
Avoid over heating your engine!!!!!!!!!!!
The heat of a new engine can be directly related to engine rpm, load and friction.
Do not lug the engine. If you have a 6-speed transmission do not run your bike in 6th gear during break-in. We strongly recommend you keep
the engine rpm above 2400 and below 3500 rpm for the first 500 miles and run the engine at varying speeds. Setting the Idle at a minimum
of 900-1100 rpm during break–in is desired.
Short trips under 10 miles and not in traffic on the first 2 rides are preferred. Try to ride on cool evenings and do not idle the bike very long.
Keep air moving around the engine to keep it cool. Making the next 3-4 trips fewer than 30 miles will help to keep the heat down. When taking
your initial rides on your new engine do so riding solo to avoid lugging the engine. If the engine feels like it is getting excessively hot shut it
down and let it cool. Typical engine oil operating temperatures are 165°F-205°F degrees and should not be exceeded.
If an engine overheats during break-in due to improper ignition timing, improper jetting, or excessive heat you can collapse or (stick) a
piston which may not be covered under warranty.
During the first 500 miles of operation we highly recommend running the engines on open road at varying engine speeds. If you have an oil
temperature gauge try to keep your engine oil temperature below 200°F degrees even after break-in.
For the first 1000-1500 miles you should monitor your engine temperature and always avoid prolonged idling or sitting in traffic. If you get
stuck in traffic pull over and take a break. DO NOT break-in your engine at Daytona or Sturgis or any other rally.
After 2000 miles avoid running your engine above 5500 rpm and if your ignition has a rev limiter, set it to work at this RPM. In most stock
Ultima
®
engines no additional power is made above 5500 rpm and running the engines at these higher rpm’s will only shorten engine life
especially on poorly tuned engines.
