For what it's worth when we first bought a Rhino 700 in 2009 I changes the oil at 10hrs to the factory recommended 10W30 then I switched to Rotella 5W40 synthetic and noticed a major difference in how the engine revved and shifted. Not sure if your Pioneer has a shared sump along with the transmission but if it does you may want to consider an HDEO like Rotella or maybe a full synthetic like Castrol / Mobil 1 OW40
Rotella T and T6 meets the JASO MA spec. Many many people use it on all kinds of bikes quads and other stuff with a wet clutch. It's also not $12/at like boutique oils with a bike on the front. It also makes heavy equipment last for 25K miles lmaoIf the transmission and engine oil are the same, do not use an automotive oil that has the "Energy Conserving" label on it. They have friction modifiers that can cause clutch slippage. Use a motorcycle specific oil or a HDDEO that has the JASO MA ratings.
maybe you need moar magnets

Yep, I used Rotella T6 for years in my ST1300. I work for an oil distributor now and can buy the Shell Advance Ultra 4T for about the same price as a gallon of T6 from Walmart. I don't notice any difference between the two in my bike. I also have over 100k miles on the bike and the T6 didn't cause it to blow up!
