Good afternoon.

I am learning how to clutch/shift. The video links are one from the right and one from the left of the bike, with my first effort. I need to adjust the clutch lever rod, I’d say. And, of course, develop some technique. This is the first time in my life that I have worked with a foot clutch/tank shift and need to be very sure of myself before I put this out on the road. I do not want to hurt this bike, and I’m pretty sure my customer does not want me to hurt it. He has asked me to do the first 50 miles, and I most likely will do that.

It will come to me. It is fun, just sitting on this bike.

Hopefully, my customer will like this bike.

Small issue, he has a fuel strainer and the fuel line from the crossover on the fuel strainer he brought has a different thread. I was hoping to hook up the hard fuel line, today, after the first trial with the clutch/shift and not need to use the fuel bag for future learning. But…

Anyone know what should be on this bike? He did not bring a fuel line from the cross over, so I ordered one for a 1948, which would fit on the Linkert float bowl, it appears, but without the strainer.

Also, any guidance on technique and/or adjustments that you can see I need, please let me know. I am in a steep, clean slate learning curve with the foot clutch/tank shift.

Thank you.

Bob

Naval Aviator! Cool. So is my son, though, now he is retired, too. :-) Age advances.

Yes, O-6, Mustang. Went in an E-2 (some college) in 1966--Came out an O-6 in 1999 (lots of college). Good career. I was a Hospital Corpsman, in-service commission to Medical Service Corps.

The CAP'N in my business name came to me because Eddie called me Cap'n Bob. We were stationed in Portsmouth and I needed help with my 1978. Eddie had a shop, Boomhower Cycle Specialties in Chesapeake. I spent a lot of time there. He sold me the 1947 engine I have in the trike, and he put me in touch with the man who sold me my 1953 Pan. He has helped me in person and via telephone ever since the early 90's, when I met him. So, in honor of Eddie, I named my business CAP'N BOB'S BIKES, Inc.

What did you do in the Navy?

I just now saw your question, Cap'n. I was a pilot. I flew A-7s off the USS Carl Vinson for a few years. Separated in 1989 after 9 years active duty.

Law of unintended consequences bit me. The throttle cable clamp worked well, right up until I was installing the left side fuel tank, then it was too big/tall. So, here is my solution and a video link to show it also works, this time with the fuel tank on! :-) Pictures 3 and 4 are not a repeat, they are to show that the linkage works all the way with the tank on. And, the clamp is nigh on to invisible with the tank on. Time to powder coat!

Marry Christmas. Thank you, all, and especially Tom.

It works, Tom, I am going to leave it alone! :-) Controls the idle and revs up and pulls back down easily.

Is there a way to hook a spring on that linkage so the throttle pulls back to idle when a person lets off the throttle, instead of needing to push it back closed? Ok, so that does not sound like I am going to leave it alone, but assisted return for the throttle plate seems like a good idea, if it is doable.

If your livelihood actually depended upon it, Cap'n,...

You'd know better than to try.

That certainly illustrates what I meant by 'flex', Cap'n!

If it works, don't fix it.

This is for Tom Cotton to see how smoothly the throttle works. With any luck, this link will work: https://vimeo.com/658238466

Went to their site and ordered a pair. Thank you, camsaure

For pan cover gaskets, I swear by REAL brand. They are silicon rubber. I run these on my 50 and do not use D rings and they never leak a drop and are reusable. The REAL gasket company makes rocker cover gaskets for antique aircraft engines. But the proprietors are antique motorcycle enthusiasts as well. I have been running their pan cover gaskets for years. You can find their website by doing an online search.

I will look them up on the internet. Thank you camsaure.

You're a good man Cap'n Bob! You have a a great attitude and . . . a retired squid, to boot!

Did you retire as a "Cap'n", O-6?

Cheers from a fellow squid

Anchors aweigh!
