I really wanted this book but no transaction should be this difficult

.

HPbyStan

Guess I didn't order it after all. Just got an email that my order was canceled and my PayPal account wouldn't be charged ?????

HPbyStan

Ordered the book. Tks to those who helped.

HPbyStan

In simple enough terms that a thick headed Yank can send for it .TIA !

Thank you guys, I had a good day. March 15th, big day, Stan turns 77, BSA buys Triumph lock stock & barrel in 1951, I go from only being allowed to lift 10 pounds clear up to now 25 pounds. Whee,

Stan has been fondling nurses and making sure all the latest medical equipment is up to date. He is now supposed to be taking it easy with his feet up, so if anyone winds him up and raises his blood pressure, THE MODERATOR WILL BE ROUND!! Hope you are feeling better now Stan :cool: :lol: Last few d...

Well, here's Stan again talking about 20/50 Ams/Oil as a cure all. Ams/Oil s base stocks are so good that they don't have to add friction modifiers like most synthetics which cause clutch problems. One of the major USA flattrack race teams used Ams/Oil in their Rotaxs to cure the clutch problems the...

If one was worrying about kick back with 34 degrees BTDC, why not just use the 15 degree advance points assembly.

HPbyStan

Speaking of looking the part, that ride looks like a show bike.

HPbyStan

Like.

HPbyStan

I'll give that a go Barry, TKS !

I found a really clear photo of my rear motor mount fix BUT the damn computer won't let me cut and paste it. I've been trying different plans for three days now with no success.

HPbyStan

Photobucket has sure turned into an even bigger bad joke. They now want $500 USD to rescue MY pictures from there.

HPbyStan

Very clean ! Nice job Midgie.

HPbyStan

Gerry did get the password problem straightened out for me :-)

6 cylinder Mercury Marine outboard engine. Has the right threads, right dia., and 1/2 inch longer,,,,, Or just have Ed make them up for you.

HPbyStan

Thanks mates ! I see I even made it onto the www.vft.org/vftforsale2.html page.

HPbyStan

You guys are quoting numbers that are being measured at all different valve lifts. You need to get on the same page and THEN compare numbers.

HPbyStan

If one lives long enough one can see / hear all kinds of stuff imo.

HPbyStan

If the inlet opens at 51 degrees before tDC @ .040" lift, your cam is too far advanced and wont be a big rpm'er.

HPbyStan

I didn't realize any of the B25 rods came without the oiling hole. Shows ta go ya what I know these days.

THIS IS PROBABLY THE LAST FRAME I'LL BUILD FROM SCRATCH. Bike is now racing on the South Island of New Zealand. http://i296.photobucket.com/albums/mm170/HPbyStan/BSA/DSCF0022.jpg When last I was at your web site, you were talking about building your own frames. What became of that ?

I think you should replace the unit. Those tabs are prone to breaking without having been hammered flat. Just make sure you don't get one for a Triumph twin as while they look almost the same, they rotate in the opposite direction so the advance unit is backwards as well.

HPbyStan

If you have a large gap, the gearbox mainshaft spacer is the same ID as the camshaft spacers.

HPbyStan

IMO, you want the heaviest cam wheel you can fit in there for inertia. The cam wheel dia. is too small and only going 1/2 engine speed to gain anything by lightening it and there's not enough lobes on the shaft to smooth out motion the for and aft pressures that the valve springs cause. If you want ...

HPbyStan

Yes I think it is the wise thing to do. Although it seems good enough to run, this engine is a little low on compression, and it appears to be leaking past the piston and rings rather than the valves. It also has traces of Red Hermetite on the rocker box and cylinder base joint, I hate the vile stu...

HPbyStan

Wow,,,,,,,,,,,,,,,

HPbyStan

Unit singles aren't perfect to be sure. They do however let one fix everything except in my opinion the camshaft area is too tiny and we can't get proper cam lobe shapes. I've changed the rocker ratio to try to bandage that problem. Otherwise it is really rewarding to see the improvements one can ma...

Probably BUT, since I had cataract surgery, I can't focus on squat at close up so I leave my glasses on now. Cataract surgery is great for looking a mile down the road and really helps night vision. People that didn't need glasses to read with before are gonna be POed though imo.

HPbyStan

HaHa, I feel your pain. I had almost given up Tig welding steel as with the "high freak" only on to start the weld, I had almost no idea what I was doing or where I was going. I also bought a 2x lens for mine and now it looks like I know what I'm doing again.

On my B50 flattracker I used a pyramid reed valve that was sold by a company in Carol Stream, Il. USA, right after 2 smokes started having reed valve induction systems from the factories, as a retro fit into enlarged non reed intakes. It worked almost too well as a crankcase breather as the 40mm DeL...

May the force be with you,,,,,,

Some time ago when I was still running the B50 flattrackers, every time I tried "modern" electronic ignitions from whomever it lead to engine failure of some kind or other. It wasn't until after I'd quit racing full time that I saw a Pazon ad about their electronic ignition NOT being effec...

Del West 350 Chevrolet titanium valves need to be cut down to B50 dias.

HPbyStan

An interesting project !

HPbyStan

That sure looks more like it huh.

HPbyStan

Where is the 2ed spark plug so both halves of the combustion chamber produce power ?

Just teasing mostly.

HPbyStan

one can get out the aluminum wrench and make the cover fit anything.
I'm not sure why one would use any part of a C15 if B25 stuff were available.
