Hi All, I mentioned on a few threads the option of fitting a Mosfet based R/R as a replacement for the original items. Since any improvement would be a good thing rather than having fried wires and stators. Anyway, there is a new type available which is described as a "Series Reg-Rec" and to use Shindengen's description "These regulators rectify the output from a three-phase generator, charge batteries, and control charging when battery voltage is high by opening the generator input." Shindengen Japan http://www.shindengen.co.jp/product_e/electro/reg.html I recently purchased one, for my Yamaha project, as a kit with connectors from http://www.roadstercycle.com/ Looks like this. The supplier was prompt and friendly. And you can find a lot of discussion about these at http://www.vstrom.info/Smf/index.php?topic=20426.0 I have nothing to add to the discussion. I trust the Japanese manufacturer and they have produced a better product using better technology. This unit can handle a maximum of 35 amps. That is good enough for me. cheers Blair
Given the amount of overheated alternator connectors that owners have posted pics of, I would describe it as the best option for the 250s. It may not be the cheapest, but in most cases I think cheapest is just a waste of money. cheers
Ive not heard of any problems with the FZR250 RR ..... but it is a piddly looking thing And of course any upgrade has to be a good thing I think its the FZR600 that has an RR fault by design .... theres alot about it on here http://fzronline.com/forum/ The ZXR has the problem of bad positioning/no cooling / overheating /burnt wiring which would of course be nullified from a much more efficient setup
What I forgot to say is that the most significant improvement would be extending the life of the stator. Replacements, or having them rewound, can be an expensive proposition and in that light the money spent on the reg-rec upgrade is easier to justify.
