Nice collection of parts;)Cam chain tensioner should be ready by the end of next week.
What size is the bore ? There is a set of 71.25 flat tops on for sale right now.
Nice tech porn pics! What about an inlet port view? Head port job is always interesting.Guides are stock steel?You will add additional case breather? Modification of the clutch cover works fine on mine. I should have been aware of this for 35 years ago.http://forums.sohc4.net/index.php/topic,172703.msg2010515.html#msg2010515I saw that mod a video of Mikes bike. //www.youtube.com/watch?v=y0I5q8-3DGc
Wow that looks great. Perhaps that "B" Turbine, even with the .40 housing, will get to spooling up even lower rpm-wise at moderate load. I think it should be a great road combination. At one time I had toyed with the idea of that F40 set up coupled to a B25 turbine for my street cruiser, using the 108 LC F-2 cam. The thinking was quick spool for very short bursts before the backpressure became an issue. So I'm excited to see how your system works out.What retainers and springs are those, are they coated?
Consider cryo-ing that extended kick shaft.They bend far to easily as is. Cheers,Brian

CB750 Racer, ya should have seen the inlet ports that Mike did on mine, they looked like they might swallow the carbs, haha.

Looking good! A lot of nice parts going in.... and I´m jealous of that lockup clutch with extended kickstart shaft! The stock clutch works also quite good with heavy springs, but with a drawthrough setup which is more agressive I think the lockup is a good idea. I also have a lockup clutch on my Kawasaki as it slipped over 15psi.Now that I think about it.... that extended shaft with spacer would make my kickstarter clear my footpeg!

The shaft is thicker than stock so I think cyrogenically treating it should be sufficient.Quote from: Ilja on July 08, 2018, 02:26:14 amLooking good!

The softer clutch pull really made the lockup clutch attractive. The extended kickstart shaft was just the icing on the cake. I don't think this engine will see more than 10psi often, race fuel just gets to be a hassle for longer rides.APE Pro Street rods just came in they look absolutely flawless. My 96 link DID 219FTH should arrive any day now which is the last part needed before assembly.Still in search for a ATP turbo intake manifold for a cb750 still offering 100$ finders fee for anyone who can source one.
