Hi, I'm David Hauff from Grand Rapids MN, currently in Duluth MN for school, double majoring for cnc programming and welding with a minor in computer drafting. I've got a little experiance wrenching on bikes. I started out with a pair of '71 and 72' Honda ct trail 90's from my grandpa, then my dad's '78 honda xl250s, then I was given my '70 honda cb 450 k3 when I was 16 from my cousin when he was deployed in Iraq. Some day that bike is going back to him once it runs but thats why I'm here is to seek help to get it back running again. After I found out it had a hole in the left piston I bought a '80 honda cb 750 custom and I've had carb problems since day 1. I also sometimes run my dad's '77 fully dressed gold wing but I firmly beleive strip 'em down and ride 'em hard is the way to go!
