THIS LISTING IS FOR A CUSTOM CYLINDER BIG BORE JOB FOR "YOUR" 90CC CYLINDER

WHICH WILL TURN IT FROM AN 89CC INTO A TORQUE-IER (((104CC)))

SO, YOU SEND US YOUR (((CLEAN WITH GUIDE/DOWEL PINS REMOVED))) CYLINDER AND WE WILL RETURN - YOUR CYLINDER, WITH, A FRESH BORE TO MATCH OUR 54.00MM BIG BORE PISTON KIT.

=============================================================================================

CT90K0_to_1979 OR ABOUT 1966 TO 1979

ATC90 / US90 ANY YEAR

ALL ST90 S90 SL90 CL90 AND CM91 'S

NOW FOR THE CYLINDER:

(ONLY ONE INCLUDED) PLEASE PACK IT LIKE IT WAS AN EGG

WHEN YOU SEND THE CYLINDER INTO US BE SURE TO INCLUDE THE ORDER NUMBER,, WHICH WILL BE SENT TO YOU IMMEDIATELY AFTER YOU CHECK OUT VIA EMAIL.

WHEN PACKING UP YOUR CYLINDER DO "NOT" USE JUST PACKING PEANUTS AS THIS WILL ALMOST GUARANTEE A BROKEN FIN.

THE BEST WAY IS TO USE SOMETHING LIKE AN OLD BEACH TOWEL AND MAKE IT INTO A BALL, THEN IN THE BOX.

JUST ALL CARDBOARD DON'T ALWAYS WORK EITHER.

!!! WE WON'T BORE OR BE RESPONSIBLE FOR A CYLINDER DAMAGED ON THE TRIP TO GET TO US !! (IF BROKEN ALREADY, JUST TELL US BEFORE YOU SEND IT)

PLEASE HAVE THE TWO CYLINDER GASKET SURFACES COMPLETELY CLEAN OR WE WILL HAVE TO START CHARGING A CLEANING FEE.... THANKS

WE HAVE TO / MUST SEND IT BACK TO THE ADDRESS ASSOCIATED / LINKED TO YOUR PAYPAL OR CREDIT CARD ACCOUNT (SORRY NO EXCEPTIONS)

IT WILL COME BACK TO YOU BORED OUT AND FINISHED WITH THE CORRECT CROSS HATCH AND CLEARANCE TO MATCH THE INCLUDED PISTON KIT. SEE THE 2ND PICTURE TO SEE THE LOWER SKIRT THICKNESS,, NEVER A PROBLEM !!!! BEEN DOING THESE FOR 40 YEARS (:

=============================================================================================

THE PISTON KIT:

(ONLY ONE INCLUDED) THIS PISTON LOOKS JUST LIKE THE STOCK PISTON WHICH HAS THE LONG SKIRT.. I BELIEVE THIS WILL GIVE A BIT LONGER LIFE SPAN.

THE RINGS WITH THESE KITS ARE MARKED R1 AND R2 FOR THE TOP AND 2ND RING, THEN THE NEW TYPE 3 PART OIL RING. THE NUMBERS FACE UP ON THE TOP 2 RINGS.

THE TOP RINGS ARE .97MM THIN RINGS FOR BETTER BREAK-IN AND LESS FRICTION.

OK WITH THE 53.50MM KIT YOU WILL STILL HAVE THE ROOM TO RE-BORE ONE MORE TIME , TO ONE OF OUR 54MM PISTON KITS.

BUT IF YOU GO TO THE 54.00MM,, WHEN YOU HAVE TO BE REWORKED THE NEXT TIME ,, YOU ARE UP A,, "YOU KNOW WHAT CREEK". BUT THERE WILL ALWAYS BE PLENTY OF USED 90 CYLINDERS AROUND. RIGHT ??

=============================================================================================

SO IN CONCLUSION WITH THIS LISTING YOU GET YOUR CYLINDER BORED,, ONE NEW PISTON KIT,, AND free return shipping.

=============================================================================================

TURN-AROUND IS USUALLY LESS THAN 7 WORKING DAYS FROM WHEN WE GET IT.

*** NOTE !!!!!!!!!!!!

DUE TO WEAR ON ROD, CRANK, DIFFERENT CYLINDER DECK TO DECK MEASUREMENT, AND OTHER VARIANCES,,,,

"SOME_TIMES" THE PISTON DOME WILL JUST BARELY HIT THE HEAD'S DOME.

SO

A SPECIAL SLIGHTLY THICKER COPPER HEAD GASKET IS INCLUDED WITH THE RETURNED CYLINDERS.

YOU MUST USE IT AND THEN THE REST OF THE STOCK TYPE GASKETS

IF YOU HAVE ONE OF THE OLDER ALL ROUND HEAD GASKETS THEN YOU WILL NEED TO FILE DOWN SOME OF THE TIPS ON THE INCLUDED HEAD GASKET

@ UNIVERSAL BIG BORE HEAD GASKET 335T

OLD_90CC_HEADS AND CYLINDERS
YOUR HEAD NEEDS TO MATCH YOUR CYLINDER

BUT EITHER SET WILL WORK ON ANY BOTTOM END
