I haven't been in the case to count the gear teeth but from what I can see from the drawings in the shop manual the rotor is spinning quite a bit faster than the engine. It's probably set up so max output is reached at normal engine speeds.

The shaft that holds the rotor is mounted forward of the crank and also you'll see that its gear is a lot smaller than the gear on the crank. Just as on cars this is the norm because the alternator needs to be driven faster than normal engine speeds in order to provide sufficient output.

The 05&up is better but due to limited size within the right side cavity and the diameter of the rotor,they can only get so many windings in the stator. Electrosports stator had no better output then the stock 05up stator according to what I was told from the guy at electrosport way back when. Anyone who owns a 99-04 would benefit by changing to the 05up stator/rec. But those who own 05's and up have the best thing out there.

The crankshaft is attached directly to the cam drive gear which is quite a bit rearward of the alternator. Scott B. Edit: The gear in your picture is for the starter - the gear I'm referring to is on the other side of the case and meshes with a larger gear on the crankshaft.   Logged     Last Edit: 2010/11/29 10:53 By texasscott1.   My 99 Standard Test Mule Scott B.   The administrator has disabled public write access. #325510 slothy (User) Platinum Boarder Posts: 1883 Re:Electrical load bearing capacity of the Roadstar ? 1 Year, 5 Months ago   texasscott1 wrote: slothy wrote: that gear is for the starter No, that gear is for the shaft that the #6 woodruff key fits in on which the #5 alternator rotor is mounted in your next post.

Scott B. nm..i stand corrected - now i see what you are talking about - once i thought about it - its not even in center of motor lol...   Logged     The administrator has disabled public write access. #325512 texasscott1 (User) Two of a kind Platinum Boarder Posts: 1824 Re:Electrical load bearing capacity of the Roadstar ? 1 Year, 5 Months ago   With the exception of the slick tapered mounting on the early bikes it's a pretty good setup. It provides enough reduction for a smaller starter to operate and in the reverse can spin the alternator fast enough. I noticed that 5,000 rpm spec in the manual years ago and that's not the only time the manual has left out an explanation. LOL The float setting is another bad one.   Logged     My 99 Standard Test Mule Scott B.   The administrator has disabled public write access. #326229 JourneyMan (User) Soli Deo Gloria!
