My kit was so poor in quality, it took a few hours of work to clean up enough to run. The casting boogers in the exhaust port were crazy, I thought it was carbon buildup at first. Looked like welding slag. One of my transfers is a different shape and I had to hone out some scuffs in the cylinder walls. Together and running but I may consider an a55 airsal kit over this guy in the future.

piston orientation?

just installed and only started this kit, have not rode it. On this kit the piston has two holes in it that usually point towards the intake side that ive seen on other kits but the arrow on the piston that usually points down towards the exhaust is facing up when the piston is oriented with the holes up, not sure which was it right....

I ran the hell out of this kit. It is bulletproof if you can manage to kill this kit then you a very good at doing things the wrong way. Ran this until I had some con rod knocking when I pulled the running cylinder off it was missing the top ring just completely gone. It ran like this. You could see where the ring had hit the piston and head and snagged the exhaust port before shooting out the exhaust is my guess. Ran it like this for 3 more months.... I will buy one as soon as they are available just to keep on the shelf.

I get to review it twice. Possibly the best kit ever. Easy to port out, easy to add reeds, and cheap as hell. I bored a seized one for a Kstar piston and decked the cylinder 4mm. Stock port timings are around 150 exhaust, 100 transfer. Raising it to 190/130 and running big reeds resulted in something meaner than a Gila.

I conducted some research on this BEAST before buying. Stock, it is rated at 4.2hp@5,500rpm! Imagine after porting and pipe. Huge transfers line up perfectly to Tomos A55 cases. The cast iron is definitely a bonus as I don't have to worry about nikasil flaking off after porting. As others have mentioned concern about quality, the ports are a bit rough but who cares? They're going to get ported to shit anyways! Taco rating as is: Good
Well
