Went together well, other than the flange on the exhaust pipe isn’t thick enough to fit against the manifold like it should. I had to use plenty of washers to get a tight enough seal.

Everything was perfect. The customer service and time frame from ordering to the arrival of the shipment was very speedy. I am super happy with everything. The only thing I would recommend is offering the stage one kit with several breather filters included. One for the valve cover and one for the gas tank. I had to order those separately.

Needed a clutch for my engine swap on my yamaha g2 golf cart. Your clutch worked perfect on my harbor freight 420cc motor.
