Here is the one I'm considering. Looks easy to install and lots of power.

has anybody fitted one of the enduralasts? and if so how did you find the instalation, and what is your feeling on the unit now?

There are a number of threads on this subject here. Do some searching and you will get lots of info. Snowbum did do some testing on these, never mind the specs, the omega system did put out more power than the enduralast.

I like the design of the Enduralast. It's much simpler physically than the OEM and the Omega. Also, the rectifier winds up in a location where it gets airflow. I have not had any experience with the Enduralast as a conversion but in its Moto-Guzzi OEM application it works quite well.

Thumb Endurolast alternator

I've out one of the Endurolast in both of my R100RS's ('78 Twinshock & '87 Mono). Instal is easy if you follow instructions - very clear instruction available both on delivery & on the website (also specs etc). The main advantage to me is output, & especially when this kicks in - much earlier than the stock system. That means no issues if you commute, and get stuck at low speed, low revs.

Got sick of replacing stock parts (rotors, diode boards etc).

Enduralast took me to alaska and back this summer

Mlandi (sp?) took his round the worl & he was one of the beta testers

not totally plug and play - you need to make the connections - but it is a good couple hour project if you're handy

also - unlike the Omega - the idiot light is removed from the charging circut and is just an idiot light!

I have an Omega system on my PD and it has been great. Not without problems - i.e., several "open" rotors - but Rick is awesome and you can always plug in an OEM BMW part if you need to.

Looking at Snowbum's data, it looks to me like the Endura makes its watts at relatively low rpms, while the Omega is still marginal in the same region. OTOH, the Endura didn't get close to the advertised max and the Omega exceeded theirs.

This past weekend was spent riding dirt and fire roads 2-up on G/S. A lot of the time (e.g. going downhill, technical sections, etc.), I was moving along at what was probably 2k or less (wish I had a tach sometimes). Towards the end, in one tricky section where I had to stop, I got the dreaded "click" and found I'd drained my battery down. Luckily it bump-started right up. But if it had occured at a low-point creek crossing, it would have sucked.

Based on my style of riding (little highway...), I'm leaning towards the Enduralast for this simple reason: I need the watts at low rpm's.

Of course I'm also looking into headlight switch options, LED tailights, etc.

E-kev-
A fellow ST pilot chiming in. I just installed an enduralast a week ago and it's running strong so far (it better be after only a week). The reason I didn't go with the omega is that the enduralast:
  • makes more power at lower revs
  • no brushes or rotor windings to burn out
  • eliminates the no charge condition when the charge indicator light burns out.
  • only has one component that can fail, so spares for long trips are easier to carry
The major advantage of the omega is that it is the same system as stock, just beefed up considerably. This makes it, for the most part, a bolt on installation whereas the enduralast install is rather involved. Also, you maintain the stock troubleshooting procedure. In my opinion though, there are more pieces to fail: diode board, voltage regulator, rotor, brushes, etc. It'd be a bit more difficult (and expensive) to pack all those spares on an extended trip.

I don't have either one, but have been checking into mounting a small automotive alternator somehow. I visited the local alternator rebuilder and had a good talk with him. What he recommended was a permanent magnet alternator, often called a dynamo, but had no source for them, new or used. He says he never sees them, and that if someone brings one in, he spins it (and if it spins) he gives it back to them and says it's good. He told me the only thing that goes is the regulator, or rectifier - not sure what it's called exactly, but that's all that goes bad.

Until I'd talked to him I was a bit leery of the enduralast, but now that's the one I'd go with.

I have the Omega on my g/s, and did EXTENSIVE slow riding this summer on the TAT and in Mexico--trail work, downhill double track, city traffic, etc. Never once had a problem.

+1 Enduralast

I have the Enduralast, easy install, but take your time and do it right.

I put the rectifier where the stock horn goes, nice and cool.

it has a bit of a whine, like a turbo, but you get used to it, and having all that power available is really handy.

110w headlight, electric grips, two electric vests, AND charging!

I've never had a problem with the standard alternator.

So you're saying the Enduralast is noisy??
has anyone else noticed the same?
