Part of their pricing problem is doing what they do in California. I have had long conversations with Barbara and Jim about the cost of everything from electricity to waste disposal. They have to make a minimum of 150.00 an hour or they aren't making enough for payroll etc. Their prices are high...

The port shape looks good. Did you open the intake seats to .9 of the valve OD? I am glad you mentioned the heads losing their temper after welding. Try milling a head after it has gone soft.....you will pull your hair out. ;D

Don't know what Wiseco's run at .004 unless special application (nitrous etc). Wiseco CB750 836, 915 pistons @.002 and .0019 respectively. I run 72mm CB750 JE pistons down to .0013 in my billet block....your "normal" for cast pistons. Those TRW pistons are close to 40 years old...like those...

I think at this point it would have been cheaper in money and effort to just get some new Wiseco or JE 836 pistons that fit the chamber out of the box. Those pistons are old and clunky.....the .003 skirt clearance says it all.

New. 3 piece oil ring. Part# 13011-391-004 30.00 for both sets. Includes USPS shipping continental USA

No burn out=it never happened ;D

I just ordered one...Kemp is a good fella to deal with. I have run a Hindle 4/1 with comp carbon canister for over 20 years....I have always preferred the 4/2/1 design.

Big-Serts are nice if the hole has been screwed up from a previous coil repair. I installed hundreds of helicoils that have worked fine. Many, many Time-Serts too.Many different lengths with the Time Sert compared to Helicoils....they come in stainless too. I get the Time-Serts from these...

That's a real performance 45 cut @2mm width. ;D

If the steel plate is flat and thickness OK bead blasting them works very well.

You can't have slotted sprockets as the cam flange bolts thread into the sprockets....not the camshaft flange. Slotting the camshaft flanges suck on those engines as there isn't much material. It isn't one of Honda's better designs having the intake cam driven by the exhaust cam. I have set...

Queequeg.....my harpoon! ::) ;D

PJ....you know me and my not like me (I think you don't) from The SOHC forum but I respectfully disagree with you. I make the Big Bore Billet blocks from a 75 lb chunk of aluminum for CB750's and have ported hundreds of heads and built engines 750/550 engines with 750 engines that make over 100...

Todd Henning had a problem with the inner valve spring hitting the seal and pulling it off but that was a Kibblewhite conversion kit for the 450. If the seal is non OEM maybe there is a problem

Why is that?

Once again....I disagree based on my experience with air cooled motorcycles.

I disagree. 99.9% are worn out if they have served a normal life cycle.

After 42 years I'd say all the parts are wasted. Stem tips, guides, adjusters....everything.
