Yep, Guzzi made Army Tractors. and they were 3 wheel drive too.
Harley Davidson MT500 - that didn't become the official US military motorcycle
The Kawasaki KLX250 that DID become the Official US Military Motorcycle
Eventually they opted for the KLR650 designated as the M1030B1 - Gas powered (as god intended).
Then in the interest of NOT having a bunch of bullet un-friendly gasoline on the battlefield, they decided to go Diesel. Despite every ass-hat on the planet thinking they want one (I'm sick of hearing it already) the project failed and they all essentially died a horrible death. So there...quit talking about it. It was such a disaster Hayes Diversified Technologies doesn't even exist anymore. Nuff said. If you want a diesel motorcycle, you're not fascinating or clever or the first person to think about it. Even these guys couldn't make it work.
Diaphragm Carbs -
Yep, you're boned. You can't fix it, you're gonna have to buy another one.
You know who you are...I've been to your website...you totally did this just to move that thing along on Craigslist...you're the devil and you should be punished.
Oh, then I found a website that claims to make rebuild kits for these things.
