Welcome to the site. You will enjoy your diesel bike. I've had one for several years now. So far it has been mostly dependable. Does yours run good? I was lucky in that mine ran perfect when received. What about a title? I was also lucky in that mine came with a clear title. Do you have a copy of the Operators Manual? If not, I can send you a copy. Most of the bike is standard KLR650, except for the engine. Engine parts are non-existent, so I try to minimize miles driven. I've listed problems / issues below from my experience.
1. I had a fuel line rupture while riding. Fuel went everywhere. To replace, I had to remove the tank.
2. When I first got mine, I completely drained and washed out the tank and replaced fuel with new diesel since I didn't know how long the previous fuel had been in the tank.
3. The diesel engine was not designed to run on ultra low sulfur diesel, which means the lubricity in the currently available fuel is too low. I religiously add Optilube XPD fuel lubricant to my fuel to increase lubricity.
4. My battery was dead when I received the bike, but I was able to resurrect the battery after about two days of trying. I got almost two years out of the resurrected battery after the recovery, then it died completely. A new Odyssey PC625 battery was installed.
5. HDT recommended shaving off the fins on the outside edge of the battery to provide clearance. I didn't do that. I purchased a new longer nylon bushing to replace the original one and now I don't have to shave the fins off of the battery and you cannot tell the difference in appearance.
6. I drained and refilled the transmission when first received.
7. I drained and refilled the crankcase and replaced the filter when first received. Fred Hayes was adamant that AMSOIL 3000 5W-30 Heavy Duty Diesel oil be used in the M1030M1. It is somewhat hard to find except on the internet, but Fred Hayes said that modern oil would damage the engine.
8. Last Saturday I was about 30 miles from home and had the front tire go flat due to a bad inner tube. The front tire was also somewhat dry rotted, so I ordered a new tire and tube and I'm replacing it tomorrow.
9. Never ever use the compression release to aid in starting. The compression release should only be used when purging air from the fuel system. Fred Hayes was emphatic about not using the compression release when starting because it will cause serious damage.
10. My biggest complaint is that it stands so high, my feet barely touch the ground.
