Review on Partman Replace Compatible 2GU 85540 51 00 2GU855405100 by Sam Bhushan

Don't buy this unless you want to spend money and have an ATV that runs like crap. My current CDI works fine but I decided to try this one. That's what happened with this CD box, my Yamaha Banshee wasn't revving at high speed, I was having constant loud kickbacks, the left cylinder would fire and the right one wouldn't fire, then it would switch at random intervals, the left cylinder wouldn't fire, and the right cylinder is fire. The quad worked like an idiot, actually it didn't work at all with this CD box. Used my other cdi, the quad rips it up. It's amazing how a cheap CDI device can affect performance. Revain really shouldn't be selling them, it's that bad.
