cylinder - iron wombat (i don't know for sure) bored out to .080" over exhaust - expansion chamber (on side), don't know what it came from or goes to elevation - 26 ft, from my city's wikipedia carb specs - I have a brand new 28mm Mikuni (NOS?) on the bike. I can't find specs on it anywhere. Mi...

Thanks for all the info. I will give the leak down test a try. I think the cylinder might be warped. Will try bigger jets to see if that makes it run better once I fix the air leak.

Thanks for the reply. Yes there is some free play in the throttle. It idles, as low as I can get it without it stalling out. Before it was leaking at the head and wouldn't idle at all but I think I fixed it. My clutch engages at the very last minute at the end of the lever, so I'm reving it a little...

If your air/fuel ratio is too lean will this affect rpms? I took the bike around the block and I wasn't giving it much but the rpms were getting real high so I shifted to 2nd and without barely any throttle the rpms went up so I had to shift to 3rd. This is within 100-200ft. Is this normal for hodak...

Ok I will try that thirdstone. I cleaned up the mating surface earlier today. All around the inner edge was low. The worst was in front and in back right on the inner edge. This is where it was leaking. I started with 220grit using wd40 to lubricate and did it in a figure 8 pattern that I remember s...

I got a 1/4" piece 12"x12" Ok, I will go with 200 in/lb this time. I'm pretty sure the bolts are free of any "blobs". I cleaned the outside of them up on the bench grinder and would have noticed something like that. I actually got new washers before I bolted it up so I shoul...

Thanks for all the advice I tapped all the bolts prior to putting it together and cleaned all the studs. They should have all gone on freely. When I torqued it, I did it in 5 ft/lb increments (about 60 in/lb), 3 times around making it about 180 in/lbs. I was using a bar torque wrench so I don't know...

Does anybody put anything on their head gaskets? I thought base and head gaskets were supposed to go on dry but when I put the engine together after replacing them, it leaked oil (or premix) from the front and rear on the head while running. I've got some permatex copper spray gasket I was gonna use...

Here's the pictures Socal When I got it the right petcock wasn't being used and probably hadn't been for awhile. When I hooked it up there was a bunch of rust particles/chips in the line. I pulled the tank, painted some of that rust performer on the underside, inspected the inside, cleaned and reass...

Thanks for the reply. The only number I could find was C-04828 which was on the frame between the triple tree. The mfg date is 7/72. I also forgot to mention that someone who owned it once did a couple modifications. From what I can find they seem like the common performance setup for that time. It'...

I'm pretty sure I have a model 94 wombat (chrome tank). I don't have money for a manual so I need some help from someone with a shop manual for this bike. I need to know the oil grade/how much, spark plug (the one in it is b5hs but I saw somewhere that it's b8hs), spark plug gap, chain tension, and ...
