High torque starter ?

 Wondering how well the stocker does on a big bore,or higher compression engines..... and, is there an upgrade?  thanks

Yes, there is a guy that rewinds them for drag bikes. Try the search function...

Call Paul Casio 504 393 2260. A good man to deal with.

The Paul Casuo rewind is an amazing starter -- BUT, just 2 things you have to remember with it -- you can't try to use it with a low battery and you can't keep it spinning like for a compression check or if you are having starting issues or you will burn it up. 

Another option is the 4 magnet starter off the XJR (RPM carries them).

Simi Ed has had hot start troubles with his big bore engine....even with a 4 brush starter.

So, being the clever guy he is, he hooked up some relays to a 2nd small lithium battery, and now he has a 24 volt starting system.

24V starter, spins like nobody's business!

2 great options...outstanding!..you guys are the best. thanks a million.

Just out of interest, Is he applying 24v to the old 12v starter, no other modifications?

Yes, that is my understanding. It is a 4 brush XJR starter.

Stay tuned.

Ed will give us the details in the next couple of days.

I'm running the later 4 brush starter. BTW, when I spoke with Paul Cashio last year he told me he can only rewire the original 2 brush starter. I figured that if I toasted the 4 brush starter I could always send my original to Paul for a rebuild.
Anyway, 2 lithium batteries, a bank of relays, some wiring and your FJ will crank at 800-1,000 rpm like mine does.
Details to follow ...

It is much better to run higher voltage through an electric motor than low voltage.   Obviously too many bolts through it will kill it, but most 12 volt starters will do fine on 24.   Running any starter on low voltage is worse and creates a ton of heat in the windings and will burn one out - in short order if you constantly grind on it due to starting issues

Edit: The bike runs on 12V, but starts on 24V.

Maybe this can help somebody  http://www.1st-to-the-finish-line.com/products/Descriptions/TBB-1324auto-harness.html   Makes things a bit easier if you go the 2 battery route

Leaving aside the wisdom or necessity of this mod, as mentioned, the high voltage in typical use should not be a problem but the mechanical engagement of the starter motor with the engine could be.
The components were not engineered for that sort of load or speed. It was common practice on 6V cars for many years where the pinion connects directly to the crank and all the parts, including the motor itself and the housing it bolts into were much more robust, even then, there were failures.

Increasing the speed, the torque and the load (compression and capacity) is a triple whammy.

Depending on the type of vehicle, sometimes you get away with it and sometimes you don't. I have experienced both, never on an FJ though.

The fact that someone has done it and not had problems to date is not necessarily proof of it's success, but then again, it might be!

Just something to consider.
