Does anybody know (KNOW) anything about thees motors. I wonder about the stock valve port size,in and ex ports (cylinder outlets)themselves, combustion chamber size etc. I don't think stock there's much other than wide stud spacing,nice size cyl walls. I run a 122 main jet. runs good. Does anybody have a mean custom built 80mm stud space ship? Any info on period

I know that the heads are totally different than the standard GY6 head. They have a cooling chamber that goes between the top of the cylinder and the cam support. Certain parts are hard to come by, such as cams. I have read that they can be bored out to a 232cc, but I have never seen a kit or any other info on how to do it. All though a 232cc motor in a 150 sized motor would be supper cool......

Top quality performance camshafts in three different configurations. These come in T-one (high 5.5mm lift) T-100 (for midrange) and T-300 (for top end). These cams are high heat treated and ground to shape. Good quality bearings. These are for the discerning engine builder only who knows what they are doing and knows what they want. Fits standard GY6 engines as well as our gy6-200 and the BN 150. Choose your cam below for only $109.  Above is Scrappy,also I found gy6 store has Tiada rocker assembly and valve seat. I think these will work if I blew Valves. You defiantly need 80mm stud spacing! Never heard of cooling chamber. Any pics and experience on these appreciated. Opinions welcome too |

Those will work if you plan on changing your head to a standard type GY6 head. The cam installs into the rocker assembly and then the rocker assembly, with cam installed, is bolted to the head on the 161QMK. The chain sprocket is bolted onto the end of the camshaft with two bolts so you can get to the C clip that holds the cam into the rocker assembly. Those cams will not work and the rocker assembly will not work with the 161QMK head.

ouch, I already got 1 odd ball (pathfinder) thought that was bad. No way near this. Well, I change oil with royal purple before black, and do valves lots. That's why they say-the best you can hope for is to die in your sleep  |
