Lovely job, Peter is a friend of mine and does a brilliant job on reworking those starters. He even upgraded mine roughly 15 years ago to more windings and therewith a bit more power, water-sealed it and added new contacts etc. Runs sweet and reliable still today in my 180° Jota (ND)!
 
realy?
I know that you have to use a different gear to use the SJCE in an old Bosch engine.
Also the orig. gear from the Bosch dont fit the freewheel in a 120° engine?
Am i wrong?

there are transition-models. my 180° ND engine has the Bosch-Starter, though it shares the general setup with the 120° Jota models. Not sure if SJCE maybe started with the RGx-Series maybe??

Piet will know for sure... ;)
 
My Jota 120 has an old Bosch 180 starter motor fitted it works a treat. The number of teeth on the pinion is the same as an SJCE starter. As I said before the starters are completely interchangeable. You can of course fit an SJCE starter to any 180 engine.

Yes - the only thing that does not work is using the starter gear of the Bosch starter on the SJCE or vize versa. The gear itself is different, hast the same number of tooth though. See:

That's one hell of deal for a Breganzie starter - I paid $900 CAD for a Bosch starter back in 72 when I inadvertently hit the the Starter button while down shifting into 2nd from 3rd at 7500rpm and turned the innards of the starter into ash. I grounded the Starter Soliniod through the Transmission Neutral Switch after that.

I also had to straighten the back plate and tack weld it on the flywheel.

I had no alternative but to buy that starter directly from the Breganzie factory at the time costing me 1/2 the price of what I paid for my 70 Breganzie 750SF brand new ;o(

After complaints, the Breganzie factory rewired the starter circuit by integrating the clutch lever depression cut out switch. I would sooner forget that and just ground the Starter Solenoid through the Tranny Neutral Switch.

My basic mechanical knowledge makes me think the crank spinning at 7500rpm could in no way allow the rollers to grab, if the go button was pushed inadvertently.
Or am I overthinking it??
 
what people forget is that the Bosch starter has a spin out bendix and doesnt need it, due to the sprag clutch engaging and disengaging the drive, the SJCE doesnt have this bendix, and as Alan J states they both interchange 100%, why would you want a bit of SJCE with a bit of Bosch integrated into it, go for one or go for the other.

If the Back Plate is loose the Dogs or as you say the Barrel Pins will Grab if you inadvertently hit the starter button at Hi-Revs and engage the starter - I know BETTER that the starter clutch failed. That's why after replacing the starter and repairing the starter clutch, I wired the starter solenoid through the transmission neutral switch to ground so the starter would only activate in neutral to prevent such an incident from happening again if I accidentally hit the starter button while in gear at Hi-Revs - Meaning I had to be in neutral to start the engine - Believe what you want.

How TF else could you explode a starter and turn it to ash if you did not engage it at H-Revs ;o(

As I previously pointed out, sometime in 1971 the Breganzie Factory started to use a clutch leaver starter disengagement switch to stop this issue.

If I had waited another year to buy a Breganzie, I would have bought a 3 Cyl Jota. The Jota did not exist when I bought my Breganzie.

Hmm ... I'm wondering if your starter solenoid might have jammed in the on position. If your starter motor was burnt (you describe it as "turned to ash") then it sounds like it may have overheated from being continuously energised. Inadvertently hitting the starter button may have been a red herring. If it was purely mechanical damage from being spun at high revs, I could imagine it being smashed to bits, but not necessarily burned.

Happened because the starter sprocket was picked up by the rapidly rotating starter freewheel - nothing to do with the starter button - unless doing that set the rollers into a frenzy and they went sideways down there and caught up and seized. I blew mine because I fitted a new starter sprocket and didn't ensure an adequate amount of sideplay.
 
That happened at the end of a day after terrorizing my territory, I would have noticed my starter dragging - It happened all at once when I inadvertently hit the starter button while gearing down into 1st from 2nd at 7000rpm to make a left 90 degree turn off the HWY. No sign of over heated windings in the starter as it simply engage and exploded into ash. Did not stop the bike.

It was a 70 Breganzie MFG'rs wiring fault.

However it happened, Ron, as we know it's unpleasant and VERY expensive! What's the ratio between engine and starter sprocket? 4:1 or something - so 7,000 becomes 28,000 on your starter - you were luck to even find ash in there!
 
Ya! Like $900 CAD for a Bosch or Ansi starter back in 73 special order from the Breganzie Factory that took 2 months delivery time - I seem to learn the hard way ;o(

Just saying: Once I wired the starter solenoid to ground through the tranny neutral switch it never happened again. Without a Clutch Safety Switch, I had to be in neutral to engage the starter - No big deal to save a $900 Bosch or Nippon Denso starter;o)
