I started my experimenting with my wife's '89 Kawi LTD 454. Although the engine is small at 32hp its no slouch and will break the rear tire free pretty much anytime you want. I can detect no appreciable clutch slip.
With that success I tried it in my '82 Honda CB900F, thats a 90something HP bike IIRC and will gladly sit still and spin the rear tire to shreds all day long if you let it. Mobil 1 didn't change that. It did change the cold start characteristics (which was mostly what I was after) in that the bike got slightly easier to start when cold. Its still a bastard if its been sitting any amount of time, just slightly less so. -Curt Date: Fri, 15 Feb 2013 15:45:13 -0500 From: Mitch Haley <m...@voyager.net> To: Mercedes Discussion List <mercedes@okiebenz.com> Subject: Re: [MBZ] Oil (Dino) Message-ID: <511e9e59.5000...@voyager.net> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Curt Raymond wrote: > I used M1 5w40 in my motorcycles (both asian bikes) with excellent results. > Loads of people told me I'd have troubles with clutch slippage but I haven't > seen that. I guess if you use the "energy conserving" oil that can happen but > that badge isn't on the 5w40. Back in the 1980s I tried 15w50 in my CB200 when it became available. (M1 was initially 5w30) Couldn't break the clutch loose by rolling on the throttle, but if I launched it hard or shifted fast, the clutch could not pull the engine (all 16hp of it) down to match road speed. Dumping the clutch at a standing start would just let the engine rev until the bike caught up to the engine's speed. After my next oil change, it went back to normal behavior, in which dumping the clutch from standstill would result in wheelspin and a little wheelie, and shifting under power would result in the bike lunging forward instead of clutch slipping. I suppose it all depends on how strong the clutch is in relation to the engine, but 1980s Mobil One definitely reduced the friction in a wet clutch as compared to dino oils of the time.
