    Thanks!
    The jeep is usually a winter project. I've been stockpiling supplies... I'll get back to it when this bike is done.

    But...
    I have to correct you guys. It's a 3A. :thumb The 3Bs had the high hood.

    I'm taking the hippo on one last berry-gathering run this morning. :ricky The season is about over.

    Finally found the time to work on this saw mount. I almost gave up on finding the latch that I wanted; I thought I was going to have to order a gross of them from china, then I found them buried in the Home Depot website of all places.

    I made a stinger for the receiver hitch that accepts a small clevis for pulling, and I mounted a press-style saw mount above it for my bigger saw. This keeps my rear rack relatively open. Pull the pin and the whole mess slides out. Mount weighs 7# and the saw is 16#.

    I still plan on riveting the scabbard to the mount and adding a patch of rubber on top. I can have the saw out and back in within seconds. So much nicer than a ratchet strap.

    Final weigh-in with full tank of gas, skid plate, saw mount and saw...

    Front: 165
    Rear: 240
    Total: 405

    That's actually not bad! It is surprising how difference there is front to back, though.

    The centerline falls almost directly on the center of the crank. So the starter, transmission, battery, bulletproof air box... all behind center. Not to mention the ~100# of unsprung weight in the swingarm, axle and brakes. :D I think the whole thing is hilarious.

    The 2WD upgrade would really balance things out ;)

    So... the Hippo has its first major test under it's belt. Overall, I'm very pleased. It crawled up a hill with ease that I'm not sure I could have made it on my XR. Super steep, big rocks embedded throughout, and a momentum-killing 90° turn in the middle. The skid plates did their job and have the gouges to prove it. E-start is awesome, this saw mount is sooo much faster than a ratchet strap, traction is insane, and it's a downright awesome machine for clearing trail.

    The minor flaws: The weight is daunting and a little tiresome; I was riding in fear all day of losing it down a cliff. The bike is so heavy, shifting my body weight has little effect on its trajectory, so I find myself sawing the bars back and forth to keep it in a straight line. The gas cap vent kept falling off and eventually went missing. I'd really like to add some sort of parking brake, even if it's just a little latch on the lever like a quad. The shifter needs a pivot in it.

    Heres it's biggest flaw of all that I didn't see coming. The tires are shorter than the standard dirt bike, and the forks extend about 4" lower than the axle. This leaves them very vulnerable to rocks. And when they hit a rock, the added leverage rips that bar right out of your hands! If I had $1 for every time this happened... I'd have $2. But it made me very receptive (to the point of paranoid) to rock outcroppings.

    Ouch! I would be looking for forks that don't hang down so low
