Bump starting on your own is normally a recipe for dropping the bike, because unless your weight is on the saddle the back wheel will probably skid, and getting your weight onto the saddle is the hard part as it isn't nice and level to the floor like older bikes. Also once it is started (if) need to watch the clutch and and get it out of gear otherwise it can try to take off with you.

The SV is a very hard bike to bump start, only attempt with someone else pushing, even then you will struggle.
There is nothing wrong with the Stock Curvy R/Rs.Mine is stock and in it's 19th year.I have a stock R/R on a Honda CX500 that is now in it's 38th year.

As for ,"Old Technology" Mosfets were invented in 1959

The Curvy has a Vacuum operated/assisted pump and is driven from the rear cylinder carb balance spigot or at least my 1999 does

Many curvy owners would disagree with that statement. You have been lucky.

The biggest problem is lack of cooling, there is nothing wrong with the old style RR's, apart from the heat they produce. MOSFET runs cooler, hence the lack of cooling on the SV is less of a problem.

Maybe MOSFETs were invented in 1959, but they have only become common on bikes in recent years to my knowledge, presumably as the costs fell?

I went through 3 standard RR's, then I gave up and went MOSFET.

I have non MOSFET RR's on all my other bikes, none have ever caused a problem, but they are all cooled far better than than SV RR.

I've not been lucky.I've been vigilant and as for,"Many" that may mean many have been misled and reading complaints/failures from the Internet is not a valid,"Real world" testament as there are countless hundreds of thousands on Motorcycles using stand R/Rs with no problems including Curvy SV650s.You rarely see a post saying,"My R/R is working perfectly

I don't disagree that the Mosfet design is superior and if some one has had problems it may well be a cure but it by no means a common problem IMHO just a commonly,"Highlighted" one.

How can you be vigilant with a RR? It either works properly or it doesn't, and you cant do anything to service it.

When my third one failed, I bypassed all wiring back to battery, and spent the extra 30 or so on the cooler running RR to be sure. It charges to 14.3 on the nail all the time, the old one (with old wiring) was never so perfect, even when new.

Calm down.
It all came about because of the Mazda MX-5 .
Not repeated faults on the curvy....

2 for me (including one that ruined a holiday with the ladz) then I bought an Electrex MOSFET one. Unlike the 1970s there's no guarantee the Suzuki one will give up, but it's by no means indestructible. My SV is also 1999 so has had plenty of years for stuff to wear out or pack up.

You are correct in that as a solid state unit they are unserviceable however the connectors leading to them are.

Electronic devices are not,"Pass/Fail" devices.They can partially fail just like electromechanical and mechanical devices.

In the case of the Regulator/Rectifiers components inside can degrade overtime leading to on the Regulator side an increase in Voltage at the battery to a point where it ruins the battery.
On the Rectifier side any one of the Diamond formation diodes can partially fail and cause AC current through to the battery.This again will destroy a DC battery.
The most common cause of these failures is lack of maintenance of the Electrical connectors,especially the larger one that carries the three Yellow HT wires.
There is a lot of current passed through this connector and if the pins and sockets start to corrode the resistance at that point will increase.This will normally lead to other parts of the charging system trying to compensate and work harder to a point where they are taken out-of-spec.The increased resistance also has been known to melt the large connector and then the Stator HT wires short and the high current from the Stator feeds back on itself and burns out the coils.

There's plenty of pictures and posts on the net when this has happened and it's not nice and potentially lethal in the case of an Automotive fire.




Whatever unit you use please make sure that the Large connector pins and sockets are free of corrosion and electrically and physically secure.I use ACF50
http://www.acf-50.co.uk/motorcycle.htm

on ALL my electrical connections and for good measure if you ride a lot in the rain you can also double secure using Dielectric grease around the connector.
