I realize this is more than likely a "No Brainer", but I gotta ask. Are any of you guys running synthetic oil in your 450? I am a believer in synthetic oil and run it in pretty much everything. But I wanted to see what brand you guys are using, and if you've had any issues with clutch slippage. I switched my 12R over to synthetic at around 1000 miles. Nary a problem with clutch slippage. I use BelRay EXS and it has worked great, but geesh @ $8.50 - $9.50 a liter it should. I don't really want to use that stuff in the 450 because it is too expensive. I only went with the stuff because a guy at Muzzy's recommended it to me. But everyone has their prefference, and that happened to be his. I run Mobil 1 in the autos, and a lot of guys swear by it in their bikes. Also how many hours are you supposed to put on the break-in oil? I don't want it in there too long.
