New-2-Me '80 GS750L

Thanks for the Props guys... You got that right Pete. Itchin for spring already and we got 3 months to go, well maybe 2. March can be touch-n-go around here.
Sci: Thanks for the heads up I just watched the morning weather report and sat / sun are supposed to be clear and back in the 40's. Unfortunately that usually means my driveway is mud for a couple days after a thaw.

P.S. Gotta love Googlemaps, helps me long for summer!
 
So today it it got up to the low 40's, sunny and DRY. That's not supposed to happen here on the day after Christmas! :)
I did a quick pre-ride inspection, fired her up and went for a longer ride around what I call the little square, 4 miles with one road being curves.Working her through the paces to get used to how she feels. Made it to an intersection that has a small church and parked it there to check it over and snap this pic.



On the return leg I rounded the last corner and have about a 1/2 mile that's flat and straight so I grabbed a hand full of throttle into 2nd then 3rd, looked down and was going over 70. DAMN she pulls harder than I even hoped!! Once it gets past mid point on the RPMs the Kerker / Suppertrap combo begins to roar along with a pull that gets stronger the higher you go... no flat spots, no mis-fires, just a surge of smooth pulling power!! Not wanting to flog on her too much, I upshifted to 4th then 5th and took her home. Confident the oil was warm and had flushed every internal crevice, I drained it and gave her a fresh filter and 4qts. now that snow is predicted for tomorrow, She should be ready to go this spring.

That's a great shot of your bike. She looks real good out in the sunlight. One thing about that paint job is that it does a good job of breaking up the shape of that tank. Admittedly, the L tanks are not my favorite gas tank ever. Real nice work.
 
Thanks Testa... I tried to make the best of the hand I was delt. Fortunatly I wasn't going the Cafe' route on this one. The shape would have been all wrong for my vision on how those should look. But for an '80s Brat bike look that I was going after I think it fit's the bill rather well.
 
I am not sure if the paint job is growing on me or if by having it outside in the sun and in the open if it makes the paint look less busy, but she really looks good in that last pic. Glad to hear she handled like a dream was there much shimmy due to wind when you were testing her upper limits shall we say? Glad she is all good. I am planning on cleaning up the left hand controls tonight and maybe taking the bike to my buds house to see about removing that stuck bolt. Once again nice job on the bike, still waiting to see what you work on next.

Hey, Hoosier. This has been rattling in my brain since you posted it. Could I trouble you summarize the main mods you did that directly contributed to this kind of power?
 
OMG that bike is gorgeous, that is mighty fine work there HD, take a bow, another masterpiece on the road, may you have many happy and safe miles on her.

Thanks Flyboy, glad you like her!

Internal engine mods? - NONE shes a stock TSCC
The Kerker Header / Supertrapp muffler with 9 disks in it and the oiled Uni air filter mounted to the airbox in place of the Factory filter box. The sprockets are the stock ratios 40/15, rear tire is a stock "L" size 130/90-16. The front tire is up one size 100/90-19 so I believe the speedo was realativley accuate, since that should make it read slow if anything. However, the tach is really sluggish (slow) so unfortunately I don't know what kind of RPM's I was turning, revving by ear I hope I wasn't taking here past her redline...but it was still pulling.

Awesome work! I picked up a 750L last year that had been getting passed around with no one really ever getting it road worthy and that I was really iffy on myself. It only has 16K miles IIRC (which is why I bought it) but I am really not a fan of the stock L look. But what you did here... man, that redeems the L into a quite a looker!

Do you remember the handle bar brand and part number and where you bought it? I really like the way they look.
 
I really like the paint job

Thanks maddog, I subscribed to your 550L thread, keep the updates coming!

Thanks 87DaytonaPac, These bars are called "Super bike" or "Superbike" and are available from most major vendors... I bought mine from Ken over at "Cycle-X". Great place to do business and very good prices. You can find them HERE
 
... and the saga continues. I have purchased an aluminum GS1100 swingarm from gmansyz, Props to him for dealing with my trials and tribulations on the purchase.
THANK YOU!
Plans are to ride her "as-is" this summer and get her to the strip for a rude awakening while gathering more performance parts. Then next winter do another tear down and build her back up as a Street / Strip bike. I think I even know where there might be an 1100 TSCC engine setting waiting for a home and some attention. ;)

Oooooh more go faster bits hey?

What's the advantage with the swingarm from the 1100? I imagine it's lighter but does it give you better rubber options or something as well?
 
Longer wheelbase, better weight transfer to the rear tire for straight line applications, not as much as a "Pro-built" extended swingarm but at a fraction of the cost. You want the energy to propel you forward instead of lifting the front wheel.
Imagine lifting a bucket of water with you forearm straight down and bending your elbow (like doing a curl), that is stock. Now hold your arm straight out in front of you and raise it using only the shoulder, that longer reach makes it harder to lift, that is similar the leverage of an extend swinger.
Much simplified, and not totally accurate, but kind of the idea.
 
Off Topic but congrats on Making the NWG calender with the Bomber. Just went through it last night. May have to order one.

LoL and I was browsing Youtube videos and found the ones you took of the Bomber. I looked at my wife and said hey look baby its HD. She likes the bike.

Yup, that makes sense, especially when thinking of a bike for the strip :)

Hoosier Daddy................I didn't recall seeing anywhere in the post, but I'm sure I must have missed it........what did you do to your carbs as far as re-jetting with the new exhaust? I'm eventually going to be going the same route as you so I was hoping you could take some of the guess work out for me. Thanks!
