Potential Group Purchase - Wiseco GS650 741cc pistons

[Ace07]

Ok sweet. That puts us up to 16 then. Hey ray are you in for a set?

 

[Chuck78]

Ray is just one of our resident high performance engine builder professionals, he only has 16v tscc gs1100 engines pretty much, was just commenting on the price

 

[Ace07]

Oh ok thanks for the info chuck

 

[Ace07]

what date does everyone want to order the Pistons by? The sooner the better for me, but I also want everyone to have a chance at it.

 

[tkent02]

I'm in no hurry at all, but I'll go along with what everyone else does.

 

[Ace07]

Ok does the end of the month sound like a good time to close the polls to everyone?

 

[Chuck78]

Funding is looking tighter than planned, so later than that would be welcomed by me and make it more of a possibility.

 

[tkent02]

Me too.

 

[Ace07]

Sorry for the late reply guys. I am fine with waiting because I have alot of other things that still need to be done to the bike. Are you guys thinking a month out, 2 months, 6 months? I dont mean to sound pushy or anything, I just a excited about the project.

Hi from France! Possible to ship them for me? I'm building a 550 / 650 swap, could they also work for me?? thanks!

 

[tkent02]

I could possibly carry them to Germany and post them there if shipping is a bitch for you. I think most of us want them for 550/650/700 swaps.

 

[boris.h]

ok, thanks! If the price, for each would decrease under 100$ each, it would be wonderful. Could you confirm me that it is still possible to use them with a gs 650 head?
thanks

 

[tkent02]

Yes they are made for a 650 head.

 

[boris.h]

ok! So what is the status of this potential group order now? thanks!

 

[loud et]

I'm not saying I'm all in, but If it's a good spring at work here, I would really want to do this.
Just got a lead on a 650 engine too....would be nice to have one on the bench to build up a litte.

 

[tkent02]

We have five buyers counting you. If we get it to seven sets of pistons, the price will be $95 per piston. I'll do an extra set or even two if necessary to make it go, but I'd rather wait a little while, as would some of the others. I guess we'll see how much of a hurry I'm in once I try the 550/675 with the stock pistons... If it goes like hell I'm in less of a hurry.

 

[Chuck78]

Yes $95 per piston is AWESOME. If I weren't so tight on money for the next 2 months I'd be buying up 2 sets! The 650 head/piston design is by far the ultimate / mist efficient / most high performance design of all 2 valve GS's. A stock GS1000 would perhaps even have trouble keeping up with a 550-650-740 or a GS650E-740cc on tight twisty backroads. That's saying a lot. If I didn't have a GS750 & a Rickman looming to get a 750-894cc, I'd be building up bunches of GS550-650-740cc's & GS650E-740cc's, this is a really potent setup and a fair bit lighter than the bigger 4's, plus much more cornering clearance.

Tom, my local buddy David "drey6" is in between jobs currently, in college, coaching high school wrestling team, but when he gets some more regular income, he'd likely buy a 2nd set off of you this summer if you bought some spares.
If my house were sold now, I'd be buying 3 sets... for now, just 1 set is a struggle on the budget.

 

[tkent02]

A stock GS1000 would perhaps even have trouble keeping up with a 550-650-740 or a GS650E-740cc on tight twisty backroads.

Hell a stock GS1000 would have trouble keeping up with a well ridden 450 on tight twisty backroads. Quick and nimble trumps massive and stable on tight roads, unless your definition of tight is 70mph sweepers.

 

[Ace07]

Hey borish what part of France are you from? Last summer I spent a lot of time 45 min south west of Toulouse.

 

[loud et]

So aside from the cylinder boring, pistons, wristpins/circlips, head and base gaskets and honing, carb syncing....
What other machining, mods or parts will be required to make this big bore kit work?
What else will it take to fully complete the swap?
