365-372

Some 365s had a bolt on intake boot as well.

I thought that was only 362s but you are probably right. Was it a year split?

365 open port is bolt on intake.

Some cases will fit the xtorq cylinders. I've ported them on my old cases.

The 75cc xpw was from 2007-2009 or so. There were other xpw but it was 71cc as is the xtorq.

The covers, handlebar, and brake handle are taller on the xtorq with the decomp in the cover.

The decals say different numbers but they still interchange.

Like my 2065. Whoop.

Great information guys I really appreciate it too

Alright I got the answers I was looking for, now who’s got all the 371-372 parts hoarded up

The 51.4mm (75cc) XPW top end can be swapped onto an OE 372 and the XT. My brother @XP_Slinger swapped an XPW top end onto his XT successfully earlier this year.

Can anyone recommend a good aftermarket top end for a 372?

I personally haven’t done one of these in aftermarket. “Yet”

Meteor kits are good. A friend of mine used a Hutzl top end and it’s still going strong. Some guys frown upon using the ultra cheap stuff like Hutzl but the bottom line is they run and I know I can’t always afford an OEM top end. If you have the ability to refine them a little by way of cleaning up casting slag or sometimes adjusting port timing you can get good power out of them.

One of my favorite builds and well worth it.

Oem is $150 or real close. Meteoris too close unless it's on sale to not pay the difference

362's didn't have the bolt on boot. That was only on the earliest 365's from 1996/1997. Pretty rare.

50mm OEM kit probably costs about the same as a Meteor. (I sell them for $140) With that in mind, i agree with @XP_Slinger that the Huztl kits are a better AM option than the high end AM brands.

The other option is to not throw away the 48mm 365 top end that is on the saw. They can be made to be very strong runners. @mdavlee please jump in here.

If the original cylinder is roasted, then of course replace it with a larger one. But if a 48 is in good shape then have some fun with it instead of just tossing it under the bench. Can always get a larger one down the road.

I would agree with Spike60's analysis, depending on usage, going with a bigger P&C isn't always necessarily better.
Call me crazy if you will, but I think that the chainsaw "play" world would have a lot of fun with an under bore kit, more so than the big bores.

If I used a AM cylinder would I be better off using a quality piston or no

AM piston in an OEM jug can be a good idea, but not the other way around, so that's kind of going in the wrong direction IMO. Quality piston on top of buying the AM kit adds up to where you're not really saving much. And there's some consensus here that the better quality, harder rings are not a good match for the plating on many AM cylinders.

I have heard that many actually prefer the 365 over the 372 when running all day. Between sound/vibrations...the 365 is a bit smoother. I must add...this is not my experience, as I have never run a 365.

Good point Bob, I've heard that about the rings and lower grade plating in some of the AM cylinders. I personally don't prefer to mix n match piston and cylinder brands. Not based on any negative experiences, I just like to keep the parts "Matched" when I can whether they are aftermarket or OEM. The only exception to this is I would have no reservation about using a Meteor piston in an OEM cylinder because of Meteor's reputation for quality. Something I may have to do in the future on my recently aquired 394.

I've never noticed any big difference in vibration. There are both soft and hard springs available for the 372 chassis.
