Question for the experts
Hi All,
I’m taking my ‘06 twin cam with an S&S 97” kit to 106”. The 97” cylinders have 600 miles on them. My question is, do I need to deglaze the cylinders when I install the new S&S 106” pistons and rings?

I would. Within a 100 miles, all was probably pretty matched on your previous rings.
Are you doing it? It is only going to take a few seconds with the correct tools and experience.
I just went thru my Jeep and with brand new loaner hone, I had trouble actually getting a finish. (seemed to be too good (smooth)..hone was a medium.)

you do realize that you are not going to make an 06 twin cam a 107 without replacing the flywheels i hope. this kit make a 107 out of a stock 07 and later 96 inch motor, not what was originally an 08 TC88. if you are installing the stroker kit also, they usually come with the stroker piston, which is different than the stock stroke piston, so deglazing is most likely a good idea, if you question your own ability for it, it wont cost much at the machine shop.

You know, I thought about this after I posted. I believe the biggest the OP could go with the stock stroke is 100" with a 4" bore. Not doable with the stock cylinders. I believe the S&S 100" kit uses the same thin spigot cylinders the 110" kit does, with pistons appropriate for the 4" stroke.
Thanks all for your reply’s

If changing pistons but using the same cylinders, I'd check clearances.. I'd probably run a few strokes with a hone but would look at the condition of the cylinder first.

I think everyone that has posted knows that; however, your OP did not mention replacing the crank. Apparently you are replacing the 4" crank with a 4.375" crank and the 3.937" bore pistons that come with the crank but you are retaining the 97" 3.937" bore cylinders that have 600 miles on them. Deglazing would be a good idea but a ball hone will actually remove material so just a few quick strokes with some lubrication and a very thorough cleaning to follow. More importantly though would be a piston to cylinder wall clearance check (in torque plates) as Max has pointed out should be the first order of business.
