FAQ:

Q: Do you need a bottom end rebuild?

A: Many riders associate the need for a bottom end rebuild with a costly trip to the shop. However, saving on labor and parts isn’t out of the question with the help of ProX.

Q: Does my dirt bike need a rebuild?

A: Just because your bike has one or more symptoms doesn’t mean the engine needs to be rebuilt. It could be another issue causing the same symptom. Remember to always start with the easiest things first when troubleshooting a problem on your dirt bike.

Q: Will a Top-End rebuild fix a bike lacking power?

A: If the carburetor is clean and everything is tuned properly then a top-end rebuild may fix your bike lacking power. You can do a compression test to check for low compression, but a leak down test will more accurately tell you what’s worn or leaking on a 4 stroke.

Q: How long does a dirt bike crankshaft last?

A: The crankshaft is generally referred to as the bottom end of a dirt bike engine. The bottom end will generally last much longer than the top-end if it’s getting proper lubrication. A bottom end can last several hundred hours if ridden conservative or moderately. Engine vibration is an indicator that the bottom end needs to be rebuilt.
