heads

Decided to start an owners group for the ever popular Cats. One of my personal favorites, and I know there is a lot of interest...so I thought what the heck. Here is the link... share & post away !:thumbsup: http://www.oldminibikes.com/forum/groups/cat+%28hpe+muskin%29+owners+group.html

So I finally made the switch on my clone from the stock 22cc head to a 15cc head. I started it up the other night, and I didn't feel any difference in the pull start when starting. Shouldn't I have felt the added compression due to the smaller head, or would the compression release be taking...

These usually go for cheap. I got a head for $36 the other day, and a block for about $50. They are genuine OEM parts. I think the guy must be selling off dealer stock, because they came in boxes marked 'honda'. Head - HONDA GX200 6.5 HP CYLINDER HEAD - eBay (item 170594423701 end time...

Any opinions on these heads on ebay? The ad says they're 15cc. I'm sure they're Chinese, but at $20, they'd be good to experiment with. CYLINDER HEAD FOR HONDA GX 160 5.5 HP/6.5HP NEW &VALVES - eBay (item 350374332778 end time Sep-14-10 07:43:53 PDT)

I just finished doing 2 big valve heads. I got the biggest valves I can fit in the heads at 32mm intake, and 28.5mm exhaust. The heads will have everything done, surfaced, spring pockets, dual springs, 3 angle valve job, full porting, polishing, swirling, and unshrouding. The heads started...

I think it's pretty common knowledge that the older GX160s have a smaller volume combustion chamber than the newer ones, so I took some 160s apart to find out which ones have the flat top piston and which ones have the smaller combustion chamber. I was surprised to find that you can easily see...

want to see if any of you engine guys have any logical suggestions past what I have already done. I have a 1973 Honda z50A. when I first got it, it was smoking like a bandit and fouling plugs. Wet fouling and the compression was 60 psi when its suppose to be 170 psi +- 10 psi. What I have...

I have two 5hp heads for briggs. One is sandblasted in combustion chamber and is clean and grey. The other is dirty and needs a little cleaning. Looking for $12.00 ea. shipped. Or $22.00 for both shipped. Both have 3 tabs for housings, all threads are sharp. Thanks
