can i install the piston, etc. to make it a 416ex myself (beginner mechanic) without taking it to a machine shop? if not, any good shops in the Phoenix area?

 

well if i was you i would take it to a shop because....you have to remove the motor from the chassis the cylender wont come out of the frame...a 416 ex is only a 2mm bore if you can find someone experienced id do it..

 

You do not need to remove the complete engine to remove the cylinder. It will come off and clear the frame easily.
You will need to take the cylinder to a machine shop to have it bored out. They will need your new piston and rings also..

 

YOU DONT HAVE TO TAKE THE MOTOR OUT DUDE, YOU DONT EVEN HAVE TO MACHINE IT...THE STOCK CYLINDER IS BIG ENOUGH TO HOLD A 416cc SLEEVE,YOU JUST POP THE OLD ONE OUT AND PRESS THE NEW, THINNER ONE IN...GIVES YOU 416CC, YOU CAN DO THIS UP TO A 426 I KNOW FOR SURE, MAY EVEN BIGGER...

 

No the engine doesn't have to come out of the frame, but....

Actually, the 405, 416, and 426 overbores are just that, they are a bored stock cylinder. The "440" (89mm piston) setup is the one you re-sleeve for.

Unless you have the equipment to do it yourself, yes, a "416" setup will require a machine shop to bore it for you.

 

I KNOW, BUT YOU CAN BUY A WHOLE NEW SLEEVE...FOR NOT ALOT OF OF MONEY, I GOT MINE A PRO FAB, CANT REMEMBER THE PRICE, ITS A 426 SLEEVE

 

SO NO, YOU DONT HAVE TO MACHINE! !

 

Hey Bubbag,
Are you yelling at everyone or is your "Caps Lock" key stuck on?

 

Wouldn't the new sleeve cost more than simply having the stock sleeve bored? I know the mechanic shops around here wouldn't charge much at all to bore a cylinder (can't quote an exact price off the top of my head though). Unless you have your own press, you'd have to have the shop press in the new sleeve anyways.

 

sounds like the bore would be the way to go.... no need to resleeve for a small 416 bore
