Sorry I've been out of the loop for awhile!
Things have been busy here at Electrosport.
I understand your questions and concerns, and thanks for the heads up on normal freeway cruising RPM
Like I said at the beginning I don't have personal experience riding one these bikes (I've always been a sportbike guy if I'm on the street [GSX-R600 & 750!]
so the 3500RPM test was my initial guess.)
There are a couple things to point out here though.
First, I think everybody is severely overestimating the stock stator output based on Yamaha's specifications.
I have found in my testing of most OEM stators that the OEM is very liberal with there power output ratings.
I believe the stock stator I used for these numbers was from a 2001 bike.
First of all, on a completely subjective test, the guy testing the part on the bike has seen a very real and large increase in power output, in the form
of charging his battery at all RPM's while using increased lighting and accessories. While I know most of you want real numbers (which I will provide soon), take a minute
to consider those real-world results first.
Now, rather than discussing what are not real world numbers (the test results I posted above, which are NOT using the correct flywheel), here is the plan to get you guys the real deal:
I need to locate an OEM flywheel and stator from each generation of Roadstar that our ESG752 fits.
99-03 Roadstar 1600 OR
04 Roadstar 1700
Stator & Flywheel
05+ Roadstar 1700
Stator & Flywheel
I will then test actual power output numbers from each stator and flywheel, even different combinations (in case the flywheels vary slightly between the 2 generations, and you mix/matched parts).
I will then test our stator power output with both flywheels, and provide you guys with all the data you could ask for.
I believe in doing so I will prove to you the generous margin Yamaha built into their power output rating for their stator.
I will also show you power output from our part, across the RPM range.
So I'd like to ask, do any of you guys have an OEM stator and/or flywheel from the bikes listed above that I can borrow for a couple days?
I can offer a 10% discount on your new ESG752 stator in exchange for letting me borrow your parts for a week!
This will speed it up greatly rather than me going to locate and buy OEM parts.
If so, please call me or email me at the below info:
