I bought a wiseco PN K1168. It says the cylinders are bored to 1166. I bought a cylinder off Fleabay that the seller says it's a 1168. I have 75mm pistons in the kit. Is the max bore 1166 or 1168. I am getting conflicting numbers and am hoping I bought the right cylinder.

I don't know the answer but if it turns out to be the latter then your forum name is wrong huh? LOL! :lol:
 
If bore and stroke are 75mm x 66 mm then displacement is 1166.319cc

Bore x Bore x Stroke x .0031416 = Displacement

75 x 75 x 66 = 371250 x .0031416 = 1166.319

Small varations can exist in the formula depending on which method you use and how far down the decimal place you run pie (3.14).

Good Luck, Ed.

I just purchased an 1166 kit from J&E. I used there kit because I was told by many that they have stronger wrist pins. I had originally planed to purchace mine from Wiseco. At the time I also was confused about the 1166 or 1168 kit. It turns out that the 1168 is just there part number. The kit is for an up grade to 1166 with a Bore Size of 2.953" and a Stroke of 10.25:1. I completed my up grade a couple of months ago and have never been happier.

Yes you can bore the stock block out to 1166cc (75mm) without any problems, This is the max you can go without cutting the cylinder walls too thin. When a machinist bores the cylinder they also need a piston to measure the clearances. Any size larger requires sleeves, but you can only go up to 1261cc in a Suzuki Block. Any larger requires a "Big Block". Then you can go all the way up to 1500cc or larger. I run a 1428cc Wiseco Big Block in my dragbike but have run 1166cc engines in street form with great success. With the right setup they can usually run right with GSXR's of old. If not sometimes better.

The Wiseco kit part number is K1168 but it is still 1166cc. That is just the number they use for there reference. See http://www.wiseco.com/PDFs/Catalogs/CB06/SuzukiCycleStreetOverbore.pdf
This gives you all the main part numbers and general info on the wiseco kits.
 
Yeap it's the piston size that matters. In my case my pistons are 82mm and that equals 1395cc, now if I go up to a 83mm piston then its 1428cc. So a 1166 should have 75mm pistons, a 1197 would be 76mm pistons and the 1134 would be 74mm. Stock pistons are 72mm on a 1075 motor.
 
So the Fleabay seller is full of it? I should be good to go with the new (to me) cylinders? As long as they're not worn out.
 
As long as it's a package deal you should be OK.

Now if the cylinders have been honed/worn out to much and exceed limits then you'll need to go up to the next bigger MM pistons and that will require boring or new sleeves.

I've never seen a .010/.020 oversize piston once you go big block ???
 
Man, got home and the cylinder had arrived. Was really excited until I saw the present inside. Broken cam chain tensioner mount and broken fins:( Asked for refund plus return shipping. There is no way he didn't see the damage and misrepresented the item. @!#$%^&*(:|
 
Take pictures of the block and the box to show it's condition and file a claim with PayPal if you used them. I wouldn't even wait and let Ebay lock his account before he pulls the money out.

There's alot of jerks on Ebay that know they are selling junk and they expect 90 cents on the dollar and when you called them out they act like their butt's are sqeaky clean.
