BC,

If the muffler is in good condition and you are thinking of going with an aftermarket, I might be interested in the old muffler.

Thanks,

small update, but there IS slow progress. Been cleaning parts and slowly P/Cing and re-assembling. Brake system is ready to go. Wheels just need powder (need to find time to go do that).

Scored a Guiliardi F-model seat from Wobbly. I love it because it's different, but it's way bigger than I thought. Did a quick first vision rendering just to gather my thoughts. Not crazy about the Marzocchi shocks. I'll rebuild them and decide once it's "done."

Once the wheels are done, the motor will be coming out and at least getting the head serviced and rubber pucks replaced as there is a decent amount of oil coming from that area.

This is finally coming together! Turns out owning a business and having a son don't leave me much time to work on this, but I'm squeezing in time whenever I can. I have a lot of parts to assemble now! As you can see I've strayed a bit from the concept rendering.

Powder was done by Atom Bomb in RVA. They did a set of AMA superbike wheels in flat red and once I saw it, I had to coat the frame that color. Tank and tail will be silver with carbon fiber graphics.

I think so, I can't find a reason to use a tube with these and they didn't have a tube to begin with. On that note, I bought Shinko 705's but I'm thinking of going with something a little more "street" like Avon AM26's


or


Thoughts?

I know they came with 79 DOHC and on some 78SOHC bikes.

Than there were people who use tubed Comstars to run tubeless, general opinion is that being risky to some extent, the tire rim is different.

Maybe the PO was one of those people?

Tires are for a long discussion, I used a set of BT45s and was very happy with them (one front and two rear tires, total 12 000 or so miles)

But when I needed new set for long trip, I bought a set of Shinko 712s and they served me well through Tail of Dragon and ever since.

Than there are people who run or did run Kenda dual sport tires on CB750 - Andy750 is one of them I believe

I have the Bridgestone Spitfires on my 76 f model.  They are great. dual compound, good in the wet, last a long time and reasonably priced.

I've had the Bridgestone Spitfires and Avon Roadriders. I prefer the Bridgestone BT45s.  Roadriders have good grip but tend to track the grooves in highway pavement.  Spitfires do not provide the best edge grip.  Just my $0.02!

Hey all, I'm having a bit of motor bad luck and am looking for some confirmation. In addressing the head issue on the motor, I opted to swap out the studs for HD studs. Well, 6 of them are stuck good. Even tig welding nuts to the snapped portion didn't move them.

So I was looking at getting either another F bottom end or another F set of cases.

My question is, can I use any bottom end from any year for either of those scenarios, or do I need to stick with an F model?

Thanks!

One thing you can not do is mix and match top and bottom halves. Gotta use a matched set. With that said you also need to use 77/78 F or K ONLY as they have the 10mm double row offset output shaft bearing. The 77/78 F utilizes less oil returns from the top end. Better let someone chime in on that subject to determine if you can use the F top end with a 77/78 K bottom end.   
As of today 3/13/2012 my original owner 75 CB750F has made it through 3 wives, er EX-wives. Free at last.  ;-)

That is helpful. I knew something was different but I did t know what. I'll let others chime in about the F to K sharing.

Haven't touched the bike in a while due to my company growing and work overwhelming me, but I've finally had a breather and was able to clear the work table to get something done. Swing Arm has new bushings, and the Triple is ready to go in. Now if I can just get back into town to make this thing a roller.... on a plane now.



Stay tuned!
