Crappy piston poorly made

Putting everything together and when I ran it the piston broke and totally ruined my cylinder. I want my piston refund and I want a brand new cylinder!

Pros
  • Great for me
Cons
  • Upgradeable

Rings do not fit - Scooter and accessories

I am a certified mechanic by profession. I installed this below using the appropriate Reed-Will port. I placed the rings correctly. The rings each broke into about 30 pieces. Assembly lube used and used 16:1 during break-in and 31:1 thereafter. Disappointing

Pros
  • Certified GOLS
Cons
  • Bad instructions

Didn't work in scooters and implements

What I didn't like about this product was that when I ordered it I wasn't told if it was a high or low center piston, so after I bought it and tried it In order to install it I found out that it was a high center and I needed a low center. It would be nice if the product told you what it was for because now I can't return it and I don't have the money. Although if it were right it would look nice and probably work great.

Pros
  • New
Cons
  • Nothing

The window piston works by itself, it requires a reed valve assembly to compress properly.

Piston with sight glass fits perfectly, easily installed with a little "sanding" on the machined edges of the piston before final installation. The piston installed in the engine does not work! It wasn't until I added the reed valve assembly that the Roar engine came alive with more power! The fenestrated piston and diaphragm assembly is a notable upgrade! Done right, you'll notice more power, improved performance, cooler operation, and longer lifespan.

Pros
  • Handy part
Cons
  • Reliability

Exactly as described; high hole; Rings installed

The goods arrived on time, corresponds to the description. Came in bubble wrap in a small box. The rings were already mounted, which I really like because it not only saves me time, but also doesn't break them. I ordered extra rings to have on hand just in case. It looks pretty neat, there are some rough edges that need tidying up, but that's not a problem for me. I don't mind cleaning it myself. It came with a pen and pen holders. It looks like a regular two-slot piston, I'm sure. As I saidโ€ฆ

Pros
  • As far as satisfied
Cons
  • I'll write later
