If you’re excitedly powering your custom bike with an Ultima 127 engine, then you know it’s a beast of the road. Alas, like any other high-performance motor, issues can arise at times. In this article we’ll be examining common Ultima 127 engine problems and providing innovative solutions from fellow riders who have encountered them before as well as useful maintenance tips to keep that powerful engine humming along smoothly.

Ultima 127 Engine Problems

Before we dive into the list, let me first say that this is a comprehensive list of things that you may encounter with this engine, but it’s likely you may not encounter most of these Ultima 127 engine problems, or any at all. This is just to make sure that either a potential buyer or current owner knows what they’re up for with potential Ultima 127 engine problems. Let’s get into it:

Identifying and Fixing Pushrod Issues

If your engine is producing a rubbing sound and seems to be misfiring, it may be the result of an inadequate roller on a lifter. To diagnose this issue thoroughly, make sure you check for open holes at both ends of the pushrods as well as witness marks on their sides. Furthermore, if the lifter has indeed failed then you’ll observe its displacement from its place. It’s also essential that you evaluate the cam lobes for signs of wear too.

Solution: Midwest Motors can provide any replacement parts, including upgraded pushrods. If your engine is still under warranty, they’ll ensure you get the best service without hesitation.

Dealing with Lifter Noise

After replacing the cam, lifters, pushrods and oil pump of your engine, you may find it is noisier than before. This could be due to an incorrect setting on the lifters – so consider consulting a mechanic for their advice on whether these adjustments should have any different specifications.

Overheating and Shutting Down

If your Ultima 127 is suddenly shutting down and only rebooting after it’s cooled off, there are a couple potential causes for this:

  • Ignition cover: To test the engine, remove its cover and observe whether it helps. If so, adjust tune it accordingly while allowing some spacing between the cover and other components.
  • Fuel delivery issue: Ensure that the float is not stuck, needle seat isn’t plugged, and valve isn’t hanging for optimal performance.
  • Vapor lock: If your motorcycle is equipped with an emissions control canister, it might experience a problem known as vapor lock.
  • Wiring: To ensure safe operation of the motor, make sure to route wires away from any areas that generate heat.
  • Fuel line routing: Make sure the fuel line is routed away from the motor and guarded against heat.

Charging Issues

If your motorcycle’s charging system gives off an alarmingly high voltage, it could lead to the engine shutting down. Use a multimeter and make sure that nothing is higher than 15V; this can be indicative of a possible problem with the regulator. Resolve any troubles by replacing or fixing the regulator, so you get back on track as soon as possible.

Maintenance Tips for Ultima 127 Engines

To give yourself the best chance to avoid Ultima 127 engine problems, here’s some tips on maintenance that you should follow:

  • Change the oil every 5,000 miles or 2,500 miles for added safety
  • Replace the oil filter when you change the oil
  • Use NGK iridium plugs, which last longer than conventional plugs
