Are these motors that cheap that its worth it to throw away instead of rebuilding the top end?
Iv never rebuilt a i4 before.. But the vtwins have always been only a few hundred bucks to rebuild..(keep in mind that's just parts.)
Parts are expensive but for "just" a top end rebuild it is usually cheaper to rebuild the top end than buy a used engine
and it really comes down to what parts does it need
EX valves are $45 each
IN valves are $29 each
pistons are $54 each
rings are $44 each
head gasket is $72
base gasket is $26.........although you could just throw it away and go without
guide seals (16 of those at about $5 each)
considering its age---those gaskets and O-rings inside the head cover for the spark plug wells...... 4 orings at $3 each and 4 well seals at $6 each
and they are nikasil cylinders, no boring (not without getting them recoated)... so you do have to look at that too
I always go after the "known" and rebuild what is there whenever possible, otherwise you could just be buying another hunk of shit that you have to rebuild anyways
Hey I started a couple threads about doing just that..... and that is fucking expensive!
