I've been reading the many posts here, and am hoping some of the more learned posters can give me their recommendations for a unique bike, Honda's VTX. There has been considerable discussion about this topic among the VTX community, and having read most of the articles here, I can see there's a lot of misunderstandings there as well. So, I'm hoping a few of the knowledgable posters here, will share their thoughts with me.
The VTX is a water cooled V-Twin, with an 1800cc displacement. It has a very long stroke, and cylinder walls coated with Nikasil (silicon carbide in a nickel substrate). The jugs, gears, and very large wet clutch all share the same oil supply. It has a huge dual pin crank, and square cut gears. The motor runs at RPM's less than 5600, but with very high piston speeds due to the stroke length. Those coffee can sized pistons produce a lot of carbon.
Most of us have been using Mobil One red cap 15w-50, both in the older SJ formulation, and in the newer SL "syuper syn" variety without problems. There are quite a few that use dino oil of varying types, and a lot of confusion about when to start running synthetic, which oil (of any variety) is best suited for this motor, etc.
Thanks in advance for your thoughts..
