[QUOTE=Chuck78;2573954]Confusing title at first, I kept thinking of what size GS650 piston would make 710cc, or what you could do to destroke a 750!
Then I saw the clutch cover linkage... Then the 710 started making sense! Not quite as talked about as the 7/11 swaps... A hyphen or backslash would make 710 (7-10 or 7/10) a lot more self explanatory!
You're absolutely correct. I take full responsibility for this snafu... This build wasn't intended but since the 750cc ripped #1-2 cam cover out of the head I purchased another cylinder head. While waiting on parts a 1000cc mill showed up... and then the 2002 GSXR 750 called my name. So here we are !!!
I think you're going to be searching for shock springs for a while, but you may want to look into ATV and snowmobile shocks. Something of a laid down angle on one of those heavier machines could be closer to your range needed? Then you'll need different valving as well vs standard bike valving... There's likely going to be a lot of trial and error involved unless you enlist someone like Racetech to plug everything into their computer formula for a valving answer, or if you know someone with a shock dyno and you find some online calculator tool that gives you valving/damping rate targets based on suspension geometry...
I'm going to keep it old school and build my own with what I have. No fun in paying someone to do something that I need to learn about if I am going to be street racing and cruising the First Coast. When I want to dip into the 8's, then I'll talk to a shock specialist. I do however have access to a LSR holder that currently goes around in squiggly circles... on a Triton!!!
Personally I would shorten that swingarm A LOT, to maybe 2.5" or 3" longer than stock if I was only looking for higher hp straight line performance.
Are you going with a 16v 1100E clutch basket? Or custom making a H.D. backing plate for the 1000 clutch basket?
This swingarm gives me a range of adjustment from 3-6". I am NOT looking to turn corners as I have a BWM R1100 for this.
I'll look into the clutch basket. Not going that quick... yet.
Suzuki Performance Spares sell a spacer kit for the clutch cover to be able to run an 1100E clutch basket without loosing any clutch discs (as the basket has to be machined down to fit in a 1000 otherwise).
IIRC MRE sells a cover that orients the clutch cable to run down the right side.
Welded crank will be VERY necessary, from the rear tire choices alone... A lot more traction than a 79 GS1000 had available back then, & hard use/abuse could twist a crank on those even!
I've looked into this and I'm sure it's in my future...
What pistons? MTC had some bargains on some old school 74mm GS1000/1100G pistons a year or so ago. They are pretty old school though, NOS, heavier than a modern Wiseco or JE by a fair bit.
Would require 1100G cylinders, 1000 base gasket trimmed, block decked a fair bit (.020"?)
Stock.
What carbs? Can't make out in the pics. Sticking with the small port head?
Jetted 26's for now.
Best of luck.
Thanks
As this is the initial assembly, engine wise everything is stock except for the jetted carbs, Dyna S and V&H header into some $15 fleabay muffler that actually sounds pretty good. Deeper tone. I'll play with the gearing, learn about spring rates, rebound and more all while having some fun. Then after the thrill wears off I'll start adding duration and lift, pistons and more.
