Hello all, I'm building a diesel snowmobile with a kubota engine. The snowmobile is a 1962 (I think) bombardier alpine (valmont technically) that I have a D905BG put into along with a gearcase from a yamaha VK540 becasue it has low range unlike the original.
my question is can you rev a BG series kubota engine thats set a 1800rpm factory for generator use to say 3000 like you could a regular d905. I have searched all over then internet to find the answer with no luck so I turned you fine people to help me out, I figure if someone on here doesnt know off the top of there head you would know where to find such info.
Now that said I have adjusted the throttle arm so it idle's at 800RPM now and it will rev to 3000 rpm according to my laser tachometer, But I am afraid I might do damage to the engine even tho I couldn't find any info suggesting that there is any internal differences between the d905 and d905BG engine's. maybe there is a governor difference or something.
anyway enough talk here is some pics of what I have done so far.
