Re: Star
Beat, if you place the rings so that the patterned faces are against each other, surely they will turn and fall into each other and the stacked height will be reduced. I have little idea how the should be stacked, but not how you have them!! I would guess that the patterned face should be down on both....

Re: Star
hi minety
the uper ring is just flat at the lower face with a pre-ground chamfer.
so they can not fall into each other.

well, the patterned faces are not the same on both rings, just the " lower " ring has some pouches cut in this face.minetymenace wrote: ↑Mon Jul 29, 2019 7:36 pm if you place the rings so that the patterned faces are against each other, surely they will turn and fall into each other

this is my guessing two, - but should I not have full faced ringsides facing against the piston material ??minetymenace wrote: ↑Mon Jul 29, 2019 7:36 pm I would guess that the patterned face should be down on both....

Re: Star
Well, in a cupple of weeks the racing season 2019 is over.
it looks as I will overhaul the Goldie engine.
by this occasion, we would like to give it a bit more punch.
the Target could be: 636 ccm by Bore 90, Stroke 100 mm.
there is this Norfolk guy Phil Pearson, he offers something the like.
dos anyone of you knowing him ?
are there others going with Goldies in this direction ? ( except the dutch ABSAF place ?? )

Re: Star
Hey beat
Phil Pearson is a renowned guru for Goldies.
He does an electric start too, which seems very popular with the 'mature' riders we all are now! No good for your racing needs of course. You could perhaps persuade him to do B50s commercially based on your design!
Cheers

Re: Star
thanks guys so far.
if Phil is the only one, I will go this route.
just tried to start the Goldie this afternoon, - NO success
a electric starter would not help aider because the kill switch failed !!
and there is a race this weekend, so it must run

so, in state of working on the bathroom renewing, I try to repair the switch
my Hannelore is not very pleased.....

anyway, - the kill switch was working but one of the batteries got empty in heat 4 and we failed one last Lap.

Hi Beat
I remember Stan commenting about fins but unable to trace the thread.
I know Mark can 'grow' new fins, maybe worth making contact to see how he does it:

Re: Star
Hi Beat
From what I have seen from other welders work it would be grown in 'free air'.
I guess it's a long and laborious task involving welding then filing and shaping, then welding, filing and shaping again, then keep repeating until full growth.
I think we need more advice from people who have actually carried out the work
Any one?

Sorry I haven't dropped in for a while Beat, seriously impressed it is for off road. I thought it was for road use. I have been reliably told M21 crankcases are stronger. If there is anything I can help you with you have my email.

Re: Star
Well, - the front fork is done,
the gearbox is overhauled and the head is welded: now, the engine is getting a new piston ( 90 mm ) and a new Nicasil coated barrel and a new crankshaft with 102mm stroke.
will make 650 ccm in state of the 500 ccm it had....
I am wonder what the old
is able to do with this mod

Re: Star
500 to 650 doesn't sound much, but it is a 30% increase. Are you doing anything to the head/carb? What about the transmission, will it be able to handle all that additional power?

Re: Star
well, now, with this more than 50 years old piston it should bring 40 ore 42 HP, - this in best condition.minetymenace wrote: ↑Thu Nov 21, 2019 1:46 pm 500 to 650 doesn't sound much, but it is a 30% increase.

as it is consuming around 0.5 Liter of oil during a race day, - it is surely NOT in best condition, so we have to renew the engine.
with 30% additional ccm, longer stroke, renewing valves and head, it should bring something over 50 HP.
but I don't know save numbers of the output anyway......
the transmition is from a Norton Atlas ore Commando, I guess this engines are around 50 HP's, so it could hold in place I hope.
not sure about the belt drive. it is a 34 / 45 gearing now, and I will reduce it to 30 / 45 next.
I hope, it will not slip on the smaller gear, - if so, - I have to go back to the 34 sprocket, which is to long now for the use.
so you see, all is a bit " over the thump " calculation, - but I give it a try .
what is worry me a bit are the engine casings, as mark cook says.
I have welded them once already, - not sure they will hold long......

Re: Star
hi skip,
you mean the starting the engine ? yes ?---- ( not starting the all Race ? )
until now, with this 50 years ( and more ) old piston , it was not evan necessary to use the valve lifter to kick it over.
Kompression was so low.....
next, the comp Ratio will be around 9 : 1 and with the heavy Boots for MX and the mod. Timing advancer which ensures NO kickback, I guess it will be doable.....
the knobby and dirty tires makes it impossible to use a starting Rollers device I guess.
I do not have any knowledge about HOW the cases usually brakes, - any pictures around ???

I must and I ( myself or Monky Lo ) will be able to set it in motion by kickstarting I think.
