Thanks for the compliments on the seat, I think the gel was a good move to.

Looks GREAT! If you dont mind my asking, what did something like that set you back? This is very similar to what I want to do!

Nice! MAC's in Ballard - I'll have to check them out. Was toying with the idea of doing my own cover but yours turned out great!

Steve at Mac's does some nice work. Forum member rat400f recommended Mac's to me.

That's a sexy piece of bum pad there! Excellent touch to the bike!!

Nice! Funny thing is I was just thinking about asking if it was done yesterday. We drove by Mac's yesterday and it reminded me you had a seat there. Steve did and excellent job on your seat too. That guy really knows his stuff. Congrates!

So I got the dyna 2000 ignition set up and it was a breeze. With the new ignition and carb sync the bike idles nice and smooth and throttle response it 10X better than it was previously with the older dyna ignition. I don't think I ever had the bike timed properly. I am know on vacation for the rest of the year so I will have time to finish up the rest of the bike, I hope. New pics and video soon.

I am using a complete 1977 Gl1000 front end (trees, lowers and tubes and brakes) I used a taper bearing conversion kit from www.allballsracing.com

https://www.allballsracing.com/index.php/99-3511-5.html

https://www.allballsracing.com/index.php/99-3512-5.html

I am using a 1976CB 750 front hub with 1977 GL1000 brake rotors and 1977GL1000 speedo drive and speedo drive adapter from forum member http://forums.sohc4.net/index.php?topic=76835.0
I am using the axle from the 1977 GL1000 front end.

Everything bolted up nicely with minor adjustments made to the wheel spacers.

The rear wheel is from a 1976 cb750f with a stock 1977 cb750f brake rotor. This all bolted up well with minor modifications to the spacers. I don't have the exact size of the spacers, sorry.

I initially tried to use my stock 1977 cb750f tress and lowers with the 76f front hub but ran into issue. The 77 f trees are too narrow for the spoked with rotors and the 77f rotors were the incorrect bolt pattern for the 76 hub.

I am not much of a writer so I help this helps some.

Why didnt you use the GL front hub/rotors/speedo drive all together?

also, which all balls steering bearing is the top and which is the bottom?

Thanks-I'm using the exact same front end/F3 bike combo.

Essentially I did use all GL parts, the 76 750 hub is the same part number as the GL. I started of thinking I could do the spoke conversion and still use my 750f front end but it is too narrow. I already had a bunch of different 750 and gl parts so I used what I had. The easiest way would be using all GL parts. I used the machined speedo drive from forum member since I already had it and it is so nice. Once you get the bearings you will know which one is the top and which one is the bottom because of the circumference. The bottom is bigger to fit over the stem that widens at the bottom of the tree.

Hope this helps.

Ok, so the bike is close to complete, for the second time. I still need to do a shake down run, but I can finally see the light at the end of the tunnel.

I was mostly curious about the front rim, Did you use the cb750 rim to match? I'm struggling with that right now, use the 17" goldwing rear rim on the cb750f hub, or the 19" cb750 rim on the GL front hub, so they match.

tweakin · « **Reply #292 on:** December 24, 2010, 01:55:54 PM »

Thanks....

I got new aluminum Sun rims but went with the same size as a stock 77 cb750f. 19 front and 18 rear and had Buchanan's cut the SS spokes. The GL and 76 750 front hubs are the same hub.

Looks GREAT!! You took my keychain tho, I had that one before my last move, seems to be lost somewhere tho!

hapakev · « **Reply #294 on:** December 24, 2010, 02:49:15 PM »

Thanks man, i might end up using the 76F hub/rim with the GL rotors, so it matches the 76F rear wheel/rim

Great Inspirational Build.
