Yeah, honestly I started buying from them when I got a single outstanding engine the first time. It had the red insert clutch lever and ran like a champ from day one.This engine lasted me over 10k miles without giving me a single problem! I never needed to pull the engine apart, so I never did look inside the cases to see what was different, but it was the single best ht I ever saw. I recently sold the bike it is on and it's still running strong.
I've heard something about rico group motors being exceptional and I'm pretty sure this was one of them. I have never since seen the red insert clutch lever but I would love to find more of these kits to see if it was just chance.
The kits I now get all have been good running and durable as far as I know. I have never yet had one of my buyers call back with a major engine issue, so I assume they all still run. The only issue I ever had was one early kit came with a bad coil winding which was replaced free and fast.
All china kits are something of a cr-pshoot, but I like knowing the vendor stands behind his engine kits. I highly recommend these (this)vendors based on buying many, many kits problem free.

If more is better, then too much is just enough.
If you can't afford it, build it yourself.
