Disappointing Motorcycle Part for Automotive Enthusiasts

As my tests showed, this part did not hold up well during heavy use and started to malfunction within a short period of time .The only positive aspect is the initial affordable price. However, the amount of time and money spent on repairing and replacing this part outweighs any potential cost savings..

Pros
  • Affordable
Cons
  • Poor Durability and Performance.

Not manufactured to specification / potentially hazardous quality.

Valves are not manufactured to specifications/tolerances listed in workshop manual. You can even feel a lot more play in the guide compared to the series part. Leads me to believe the valves are poorly made and can fail during use.

Pros
  • Motorcycles and Power Sports
Cons
  • Unreliable
