I got the oil cooler on ebay.  just search Lockhart and some different options will show up.  The adapter puck was made by forum member Terry in Australia.

[tweakin]

Spoke wheel / GL1000 front end is complete.  I still need to bleed the brakes and while the tank is off I plan on synching the carbs.

SWEET!

Did you happen to take any pictures of the speedo plate and how you modified it to fit on the cb hub??  I'm doing a GL front end, hopefully a fishhead big brake kit too  looks AWESOME though man, seriously VERY nice work!!

Also, are those straight rate springs with the emulators?  Any other goodies from race tech??

[Zaipai]

Looking great tweakin! Well worth the time put into it..

Awesome build Howell, do you still have her?

FRESH.

I bought a machined speedo plate from a forum member.  http://forums.sohc4.net/index.php?topic=76835.0  I had to grind down the speedo drive unit a bit, but it worked great.  Those fishhead brake set ups are pretty cool but I wanted a more stock look so I just completely rebuild the GL100 brakes.

They are straight rate springs set up for the weight of me and the bike, with race tech emulators and adapters with race tech fork oil and new 1 inch under fork tubes from Frank's.  I also have a black anodized fork brace coming.  In the future I plan on upgrading my rear suspension from Progressives to either race tech or works.

Today I was able to get my stainless yoshi replica pipes mounted up.  Modified my foot / brake control brackets to fit with the new pipe.

Your bike is DAMN nice. That pipe and spokes really put your bike to a whole new level. I can't wait to see it up close and hear that pipe! You really should look into having your seat done by a pro. You did a good job on it, way better than I ever could but with all the high end parts you have into this bike don't cut corners with the seat!

Hi Tweakin... You've been very generous with your build information. Along with (I'm sure) a number of us, I'd like a very complete "how to" on the fitting of your '77 GL1000 front end with spoked wheels. So, if you could take just a little time and give us a parts break-down and any info including spacer sizes I'd (we'd) really appreciate it.

For instance, are you using the '75-'76 GL1000 triple clamps with the '77 fork tubes since (I believe) the '75-'76 triples take standard CB750 bearings and the '77-'78 forks will take the CB900 large front calipers? Are you using the early or late GL1000 rotors or the late "K" rotors? What front axle? Early GL front hub, or early "F" hub since you're using the speedo on the righthand side?

It's hard to find all the necessary info in one concise place so a list of compatible parts would be fantastic. Any direction you'd care to give would be much appreciated. TIA. RR

[tweakin]

Thanks.  Yep a professionally doing the seat has always been on the list but it keeps getting bumped back due to other things I want to do to the bike.  Actually you will be paying for the seat, lol.  With the money from the parts I am selling to you.  I just need to find a local shop I can trust.

when Twekin is done with this one...I'm gonna try to drag mine over with a couple of cases of beer...maybe magic can happen twice...

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

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.

Beer is always a good starting point...

[Ricky_Racer]

Thanks for the info on the front end, Tweakin! I didn't know that All Balls had sorted out the Late GL1000 to CB750 bearing combo. That sure simplifies things.

For some reason, I thought the '77 GL1000 rotors had five bolts like the '77-78 CB750K's. Good to hear that they'll fit the early "K" hub. I guess it's time for me to hit the parts books again.

BTW, sweet F2 build! Very classy!    RR

Looking great Tweakin, those pipes just make it perfect....

Well done!...man your bike is GORGEOUS!!! And I think that RevamP job deserves another run in the BOTM...its got everything it needs to be a superstar!!! Again...beautiful job!

[bluesmoke69]

I have mags on my 76F, but still have the spoke wheels may be changing my mind about the spokes. I did not like the look of the spoke wheels, but when the hubs are polished, and they have new spokes they look good!! Your bike is looking great!!!!

Tweakin...what bike lift are you using?  what's the height of it at it's lowest point... I just purchased a HF 1000lb lift... ( waiting for it to be shipped) and I need to be able to part my truck over it when no bike is on it...

[tweakin]

Its the HF 1000lb lift also.  At its lowest point it is 7 1/2 inches tall for the table portion.  I put on a different wheel chock for better stability.  



The wheel chock that comes with the lift is probably 5 inches on top of the 7 for the table height.

are those factory damping rods?
what are those silver parts in the center?

[tweakin]

jaguar...Yes factory gl1000 rods with extra and enlarged damping holes and up top I have brazed one of the rebound holes shut on each rod.  Once I brazed the holes shut I lightly sanded the rods, this may be what you are seeing.

I think he's asking about the two parts under the RaceTech decal. Look like maybe spring spacers?

[jaguar]

^what he said.
