Arrowhead starter motor ,shoots itself in the head

[chrisshrops]

I finally got around to fitting my replacement ignition from motorworks on the old money pit today ,so whilst I had it stripped I put a new arrow starter motor on at the same time . The bike started and revved alright before it stalled I should have kept the revs up until I had it warm,anyway I pressed the starter and got the dreaded wizzzz ,when I had a closer look the aliminium cone had shattered the motor whent in with no hassle and torqued down alright ,it must have been the backfire before it started that did for it.
I wonder if motorworks will have the pissing thing back?any of you lot used the Nippon ?im thinking the high comp pistons may need a better starter
I would say you live and learn but I don't seem to

I have a Nippon on my moorespeed engine. It's very nice!

In truth I fitted and haven't given it any thought at all since

Kind of what you want Rob

To be fair, would a standard Valeo have survived a harsh kickback whilst still engaged. The cone casting always looked a bit suspect to me

Hi Chris, the only reason the motor would backfire and kick back is the timing is way off. i only ever use the the valeo on all of my race engines apart from Eddy Wright who brought his own Nippon Denso .

Hi Richie
Yep it was off ,I will swap my busted Valero for a new one and give that a go

I think the moral of this may be do not fuck about fixing motor bikes after working stupid hours for 6 weeks without a break,you will fuck it up !!!

When I was restoring my B44VS I also found that there is a daily limit to what I could sensibly do too.
I was working on a distant construction project l my working day including travel was 12 hours, so by the time I had supper then started on the bike it wasn't long before 15 hours were up , and that seemed the limit for sensible decision making and judgment.
I found myself doing silly things like using a shifter instead of walking six feet to get the correct spanner,etc,etc. and probably a few things I didn't even realize I was doing wrong.
Not a problem now that I have retired , off course, but I still like to allow myself three or four hours for a set of tasks that I think I can comfortably complete in two to three hours, then have a decent break before starting another easy set - it is when you are rushing to complete at the end of a long day that the real disasters happen!

Nippon Denso

.... but then the same thing happened to me with TWO Denso starters! The cast bells fractured. Both starters fitted to correct torque settings and both replaced by supplier. I believe that's not uncommon with the Denso. I got the impression that the casting couldn't handle the power. Now have (post 2002!) Valeos fitted and no problems since.
