I'm sure these are in the Service manual, but i'm just too lazy to walk out to my shop right now.

What is the bore/stroke size of our motors, the compression height of our stock pistons and rod length.

I'm also curious on the diameter of our lifters....I want to cross reference parts for future projects.

thanks

from my 2000 X1 manual:

10.0:1 compression
3.498" bore (3.625" is more fun) ; )
3.8125" stroke
73.4 cuin displacement (1203 cc)

manual doesn't list rod length or lifter diameter, only service wear limits for each part.

you're lazy.

let's ride this weekend.

I need the compression height of the piston and the rod lenght to do my math...

FYI comp height is the top of the piston minus the dome or dish to the center of piston pin for those that dont know...

If anyone has a lifter out and has a caliper, I'd sure like a diamter measurement...I want to find out what lifters are availible in that diam...Since there are only 2 lifter manufactures left in this country, it wont be very difficult to cross reference that part for a more cost effective one.

If only you'd asked a couple of weeks ago.... I do have a set of lifters in the garage somewhere, but it's late and I'm too lazy to go look for them right now. I'll check back in a day or two....

.84"



I've got plenty of stock pistons around that you're welcome to come measure cuz honestly I don't completely understand what you said about comp height.
