I got the kit. The dimensions are a little misleading because its a 43.5mm should be a 65cc not 70cc. But all in all its decent there are a few things to mention one of the stud nut wont fit so i had to grind done a fin to get it to. Toss out the included intake due to it being 1mm smaller then stock. Before using the gaskets port match the cases first.

Such a gnarly-ass kit. Putting it together was easy. I did use my own allen bolts since the stock ones were not-so-great. Holy HELL does my 505/1A on my General 5 Star rip now after hella tuning.
It went from a 20mph bike to a 40+mph bike with a MLM People's Pipe + Mikuni on there.
I'm still having trouble keeping it from air leaking through the decomp set screw, but that's probably just cause I have shitty tools and can't torque it properly in that tiny space.
The airsal intake for the bing is definitely nicer than the stock intake but it sits too low. Use some extra gaskets to keep it from hitting the engine case.
Switching to the MLM VM20 angled intake + Mikuni VM20 setup is WAY better. The piston + rings + head were great quality.
The piston clips were so hard to compress that I ended up using my old piston clips from my original piston instead.

so this thing is pretty great kit and easy to install. a few things you might want to do before you install it. 1) the intake will not clear the case with out a double spacer 2) gasket match the intake to the bottom half cause its not even close 3) case match the transfer ports cause its almost laughable how blocked they are with the case in its stock form 4) maybe cut better gaskets cause the ones with the kit are pretty crappy and thin but they do work 5) get new bolts

excellent kit for the money, would recommend to everyone and anyone with a sach, bolted right up to my 78 Colombian commuter with a 505 1b engine, like all the previous comments don't use the screws provided their junk. Put over 100 miles on the kit so far and loving it, using stock pipe and carb with an 65 round Bing jet hitting 30's (mph) and the clutch is still going strong. Good low end power and high end is amazing.
So far so good
