628

Hey guys, I've had a question bugging me for a while. Is the 628 crank, conrod and piston a bolt-on part for the -04 644? Thinking of doing this once I get rid of the 644 crank. It should last 100 hours more, will see if that's enough for the short but cold finnish summer. :giggle...

bits of this build don't really fit anywhere so ill put them here I'm building a 628 from bits i have laying around, only stuff i really had to buy were cases head crank/piston. Big thanks to Mopwer for a smoking deal on these parts.. best ever internet shopping deal.

I need the weight of the OEM pin and rod on the 628 if anyone has one to hand please? Taffy

Currently looking at a fs650e 2005. This has the 644 engine correct? And is there any difference in the engines other than the crank? Is the 628 the better choice? Thanks in advance.

put a new rod kit in 20 hrs ago found some flakes on the drainplug 2 oil changes in a row lower end of the rod is a little larger than the original and lightly contacts the crank when the piston is under full steam I think on the power stroke. it doesn't contact checking by hand so the crank...
