Default Engine Knowledge?

How hard is it to remove the cylinder from a Honda foreman 450? Is there alot of work involved or is it pretty srtaight forward?
What are the bolt torque ratings for the cylinder and head bolts? Is this something that someone with good mechanical skills could handle? Thanks for your replies.

Easy as pie. It's a pushrod engine so you won't even have any timing to mess with. I'm not sure offhand what the head bolt torque is but maybe somebody here with a manual can help you out there.

I am at work and dont have my manual handy. But I would recomend that you invest in a manual. If not the honda version for $50 bucks maybe see if you can find a Haynes manual for considerably less. I work off shore and wont be home for a few more days so I cant help you much.

Yeah I totaly agree w/ Sparkey, a service manual is very handy for looking up just about any thing about your atv. But to mabey help you out a little the torque values for a recon cylinder head bolts is 22 foot lbs. so I would not think it would not be that diffrent for a forman but the $30-40 is well worth it.

I wouldn't assume a foreman and a recon are the same. I think the Foreman is more...like around 29 ft\lbs for the headbolts (also hold the cylinder on) with the four little 6mm bolts around 9 ft\lbs. You should at least have access to a manual for things like putting the rings in the correct groove and right side up, boring specs, etc. But it's really way easy. The hardest part is getting the cylinder back on. There isn't much chamfer to get the rings "started" in the cylinder. Sometimes they go right on but other times it can get dicey when you get down to the last oil ring rail. I've seen more than one experienced tech break or bend rings in the process. A second skilled person is sometimes handy.
