The first 500 miles of your new 5-port LML engine‘s life are without a doubt the most important. The parts are all new, and they all need a few heat cycles to expand and contract and settle into their correct operating tolerances. Taking your time and getting the run-in right will help to ensure a long, reliable life from your new engine.
Avoid over-straining your new engine with excessive speeds/rpm, and try to keep (more or less) to the speeds, below.
- 1st Gear : 0-6 mph
- 2nd Gear : 7-12.5 mph
- 3rd Gear : 12.5-22 mph
- 4th Gear : 22 + mph
Also, be sure to vary the bike’s speed while cruising, rather than running “steady state” or simply laying on wide-open-throttle (WOT) for long periods of time – this will allow the engine to break in properly under a variety of load conditions.
Be sure, as well, to allow 5-10 minutes of “cool-down” time for each hour of steady use, and check to ensure that the gear box oil stays at the recommended levels.
During engine break-in, it’s also advisable to check and fine-tune your engine’s carb jetting. CLICK HERE for more carb jetting tips, and feel free to call 1-888-968-3772 with any questions you might have.
