Sure you can find the, or a pair, of replacement speakers rather cheap.
Likely better to buy a matched replacement pair then trying to match a vintage one.
Look for the same OHM rating, and if you can find the blown speakers specifications,
try to match those as the ratings of the crossover is designed for various factors.

To add to the post above. It is possible to blow the resistors or capacitors
in the crossover network. And that will drop out one or more of the drivers
sound production.

My vintage JBL L65 fry'd  a resistor and the mid-driver stopped making sound.

Thank you to everyone that attended the event...
And an EXTRA BIG thank you to the event staff for putting
on such a great EXTRAVAGANZA 2021...
Also to shout out to Wolf Creek for allowing us to smoke out
their parking lot and providing some very tasty brews.
Can't wait till the next gathering.
Cheers, Jeff

  4 days to go.....A couple Q's

Where is the Saturday ride starting / going / ending.
Guessing it is Angeles Crest area, but, could it be the Rock Store?

How about an attendance estimate. Do I need the get there extra early
the secure a spot to set up an EasyUp?

Parking for the Truck/Trailer? Last time I was @ Wolf Cr. parking was
about 1/4 mile or so away from the brewery.
I had to drop all my bikes and stuff at the entrance and drive away leaving
it all piled up for several minutes.

Thanks, looking forward to the event.

  Something I was wondering about just a couple days ago.

My Austin Healey had a leaky fuel needle valve in the front carb.
Ordered a Grose valve from Moss Motors and fixed the problem perfectly.
Wondering if I should order two more for the other SU carbs....
I wonder if the thread size and valve length would work on an RD carb?

cheers,

I plan to be there. Not sure about the ride. Depending on
where the ride goes, and how far. Wolf Cr. is more or less
45 miles from my home. 6:00AM load trailer, 7:00 leave house.
Unload @ Wolf, and be ready by 9:00....... note to self, bring
extra coffee...
hmmmm? Now what bikes should I bring??!!
Cheers.

Russ = the well of knowledge. Who knew he was up on Trials bikes.?
Russ, you need one of these. Then we can do vintage Trials.
I'll  break out my TL125.

I picked a couple of clear float bowls for the DelOrto carb on my trials
bike. The leaked like a sieve and I could never get them to seal up.

Wonder if these work better.?
Cheers, Jeff

Russ, buy it. You can store it in my living room. 

BOM calendar was my favorite. I always ordered 2-3 and gave one to friends as a Xmas present.
Kept mine in the living room for daily viewing.
End of the year, I cut out the best pictures and saved them.
Understand there are often not enough quality bikes presented to make 12 / year.
Cheers and thanks to those who did it in the past.

Just thought I'd toss out the latest picture of my finished project.

Still messing around with the jetting, it ain't quite right yet.
Cheers, Jeff

Sold for $18,500  wow!!

It did look nice though.
thanks,

Thanks guys. I eventually found the torque table on page 46 of the .pdf Clymer manual.
It showed 8mm = 15-18 Ft/Lb  and 10mm = 25 - 30 Ft/Lb. I was wondering if the
studs were 8mm or 10mm, couldn't remember when it was apart.
I have an old 1/2" drive, spring loaded torque wrench that I am not super confident
in it's accuracy. Will give it a try on a larger bolt / nut set at 18ft/lb and see is it feels
close.

Next step back to the jetting.
When taking off from a stop, adding the choke seemed to improve the stumble.
Easiest would be to raise the needle one more groove. after that.....
I may go back to the 35 pilot and up the main one size more.
Cheers folks and Happy New Years.

I guess it is time for an update...
The RD250 is more or less finished. I have put around 100+ miles on
it so far.
Seems tweeking the orange point wire and replacing the points and condenser
has fixed the spark on the left cyl issue.

With the 35 pilot / 150 main with the needle in the middle clip. The bike had a very
pronounced bog from low RPM into mid-range. I dropped the clip, raised the needle to
this richest level and the bog mostly disappeared. But the bike would not pull above 5K RPM
in 5th / 6th gear.

I figured that the Needle jet was too lean. Stock it is a O-8. So I ordered two new sizes.
A P-0 and a P-2. Installed the P-2. Figuring I might be too rich with the needle clip in the
bottom groove, I moved it to the 2nd from the top. Thinking the 35 was also too rich as adjusting
the air screw seemed to make no RPM difference I dropped in a pair of 32.5 pilots.
  ( I know... never change more that one thing at a time!) I'm not done. Since stock was 120 main
I had a 150 in there. Thinking it was too rich to pull above 5K RPM I dropped the main to 145.

So?  The mid-bog was back, but it pulled well into 6-7K RPM once it got beyond the stumble...

Put the clip in the middle position and the bog was reduced, but, not as crisp as I think it should.
And with the 32.5 I do not get a pronounced rpm shift moving the air screw from 1-1/2 turns either.

Confused... Through all of this the plug colors have remained a fairly nice tan to a slight lean look.

Kind of chasing my tail, but yesterday was warmer, (82F) and the bike seemed to pull stronger
than the last test ride in the mid 60F's.
Guess I will drop the needle clip one more groove, 2nd from bottom, and see if it improves more.
Suggestions are always welcome BTW....
P.S. Was looking for the torque spec for the head bolts / stud nuts and could not find it in the manual.
Can some one let me know? Thinking it is around 18-20 FT/LB, but, don't want to screw up.
Thanks, Jeff

Excellent, very entertaining.
  I do not know how to embed a YouTube vid here, but, this one
used to be one of my favorites.

Cheers and thanks.

Carbon / Carbon brakes in 1993?
I don't remember that.
Bet it sells for more than the US average home price.
Cheers to the new owner.
