Car Starter Conversion

[fjman]

I understand that the original 84 starter from the fj1100 spins slowly when it is hot.Already tried rebuilding it but i'm not satisfied. I was thinking of converting a car starter to use in the bike. I know that I could just buy the xjr starter as to not have any problems but i'm doing this as a project. Has this been done before? If so, could someone help me out  any help would be appreciated

Try upgrading the starter you have with Randy's 4 brush kit.

You cannot convert a two brush starter two a four brush as the brush plate matches the field magnets.

It's all good, if you play, you have to pay.

I have no issues with my '84 starting cold or hot.  Are you sure there isn't some other issue?  Have you measured to see if there's a voltage drop accross the starter relay while turning it over?

The only time I've seen car starters used on bikes that I can think of is when they're outboard.  Only done at the racetrack, and involves a starting cart.

You'll have to be able to find a pretty tiny starter from a car, and honestly the only cars that I can think of with starters  small enough would be ones that make quite a bit less power (thus less compression, easier to start, etc) than the fJ.

Instead, if you wanted to be only slightly screwy, you could mount a secondary battery and have a 24v starting system.  It's a bit tricky to wire, but is fairly common for racebikes that have to fit "street" guidelines with ridiculous motors (1640cc hayabusas with 15:1 pistons, for example, under rules that say "must be self-starting").

My project 84 Fj had 4 starters on it within 1 year, the guy I bought it off of just replaced it for the fourth time just prior of my acquisition of the bike. I checked out all my wiring which was ok, still cleaned all my connections. I replaced with Randy's four brush starter, has started with no for the last 3 months / 3000 miles. Starts fine cold or hot, actually it does turn over faster and starts quicker than the other starter. I would highly recommend Randy's before trying a conversion. Just my 2 cents worth.

   Save yourself alot of time and headaches and fit a four brush starter. I fitted one to my'85 about 2 years ago and have not had a problem since.   Regards, Pete.
