Title: 916 Engine - Monster V’s Superbike Post by: MonsterMadMarty on August 16, 2019, 03:01:53 PM G’day all,
What are the differences between the 916 engine found in the Monster S4 and the original Superbike? The most noticeable visible one is no oil cooler! Cheers [thumbsup] Title: Re: 916 Engine - Monster V’s Superbike Post by: Speeddog on August 16, 2019, 09:58:38 PM Original '94 916 SBK motor?
Single phase charging system, not 3-phase Cases are machined narrower and for only the pivot shaft, bearings are in the swingarm wide ratio transmission, not close ratio Crankshaft is to suit the single phase charging Does not have the low-exhaust-cam heads Early style oil pickup screen, not internal under the plug-cover Oil pump does not have the relief valve Relief valve is in the cases Primary gears are 2:1, not 1.84:1 Coolant fittings are different Longer duration intake cams Shift drum/neutral switch is mechanical switch, not a grounding 'commutator' setup Has an o-ring on the vertical cylinder oil feed, so it doesn't get the base gasket leak Probably another half-dozen things |
