It does not fit my XL70 so if your camshaft doesn’t have bearing on it like I had(I had no bearing on my OEM one) it is not the right one buy another cylinder head but I figured out how to make it work(I stack 2 gasket on top of each other) yet I don’t know if it works but with 1 gasket the piston is hitting something but with 2 it doesn’t. And the spring a longer but are easier to compress so it might go bad at high rpm

Cylinder head looked good except one bolt on cam sprocket was screwed in at an angle. Not sure if this will work for me !! Two out of three bolts were good but one bolt was cross threaded !!

Brand new complete cylinder head should be ready to go and just get bolted on. I know how to set valve lash but that's not the problem. A leak down test showed that both the intake and exhaust valves were leaking. I pulled this new cylinder head and then in a dark room, shined a flashlight towards face of the valves. Looking down both intake and exhaust chambers, I could see light for both. Neither valve was fully seated so no way to fully build enough compression. This should net happen on a complete brand new cylinder head. I am going to return it and am hesitant to get another one from here to replace it. I think I will try another option.

Easy install. The only thing is don’t try prying off chrome cap. It has a Bolt on the other side of the head and it comes right off.

I bought this for an atc 70, but the combustion chamber design is different than the original, and the piston hits the head. I suspect this would be the same for older honda engines, but this would likely be fine for chinese clone engines. Other than that, the head was flat, and the valves sealed fine. I gave 3 stars because its says it'll fit atc 70 in the description, but it clearly does not.

Update: 1/24/2023: GOOFIT is still garbage. Update 4/20/21:Goofit (goof it seems fitting) has NO customer service as stated. Horrible. Update 4/3/21: Goofit just stopped responding. Wasted my time for a month now. I could’ve just bought a new cylinder head instead of being led on by these people. Update: 3/13/21: Goofit responded to a Facebook message 5 days ago which I replied and have heard nothing back. They have not responded. What does the warranty say above?? Don’t expect any support. Spark plug threads stripped on 2nd plug change. I used anti-seize, replaced when engine was cold and I used a torque wrench. Fit good but cheap metal.
