Good video, felt like I was in the woods with you when on full screen.
We should share what we know... someone may learn...

Nice video and  enjoyed it.

Only thing I would have done different. On the Aftermarket 372 I wouldnt use the restrictive jungle muffler. I would buy the afm muffler that exits out the top.

I would use this afm muffler http://www.hlsproparts.com/Husqvarna-362-365-371-372-385-390-muffler-p/h90365.htm

Not these jungle ones http://www.hlsproparts.com/Husqvarna-362-365-371-372-385-390-muffler-p/h90362.htm

Really informative, I really liked your comments about 'no longer a Husqvarna saw'! I agree with your approach and what message you are trying to get out there. Especially the value of using factory tools. I also am able to and do perform those sorts of experiments, some with very good results and some not so good.

Wish more would post up actual video content of the trials and tribulations! I got myself in trouble on another site by articulating one of my goals to get the discussion around these aftermarket parts, and cylinders in particular; about the source manufacturer vs. the reseller. Analogous to talking about Wiseco vs. Vertex Pistons vs. Parts Unlimited vs. Denis Kirk in the motorcycle world. ALL these parts are manufactured somewhere and many are sold through multiple channels. Would like to drive the discussion to where we talk more specifically about the actual part, ways to identify the parts, then let the reseller's / relabelers battle over the best price and sales channel to get us those parts we have identified as good and what we prefer.....lol I've got a Mako 272 thru Spike 60. Looks really good, after a hiatus from saws I hope to add it to the video library of experiences. Another guy claimed he was the only source! That's the stuff that drives me nuts.

Would love to have your story around that Husqvarna ... I'm hoping to do a video on my 1979 KTM MC80 420...

Thanks and obvioulsy good info, was trying to have a "typical" 372 as compared to a well thought out one...:) The idea is to give a visual metric on what would happen if a typical guy decided to replace his top end for what ever reason with one of these AM builds...So I've purposely build a mundane middle of the road 372 as the reference standard to compare AM things to...:) Maybe we could collaborate and build a few video's of simple things to make the mundane 372 less so....muffler mods, no base gasket, etc...:) Trying to have the "Farmer Jones" theme consistent where the changes are simple and repeatable by... Farmer Jones.

Trouble. Must have been one of those sponsor only sites.   LOL


I'm pretty much a basic stock saw guy now and leave base gaskets in. Maybe a muffler mod at most.

Thats all the local firewood guys want, saw that starts, runs, idles all day and sharp chain. 

Not worried about the speed in the cut anymore.  Used to be big time but not anymore.

Well that is a 1973 MK series Close Ratio 5-speed 400 Cross, supplied to me by Husqvarna for the 1973 race season. Usually got three bikes two race and one practice. The MJ and MK series did not handle as well in the turns as the MI series of machines from 1971! ForFab engineering in CA made a custom billet aluminum set of triple trees that improved it but Husqvarna never really corrected the steering geometries until 1976! At the end of the season they would allow you to buy one of the bikes. I no longer own the bike, it is owned by a long time friend. That is the original bike just as supplied by Husqvarna. The picture is recent, everything on it works and he keeps it in a spare bedroom. Does not leak one drop of oil!!

This is one I did a while back with the same goals as you suggest above. It would be my pleasure to collaborate on something with you. I do a 372 with a AM BB kit and use a Stihl 064 piston. They run real well and can be built by the average Joe. No porting, just a lot off attention to detail and tuning. This is not a new idea, it is in-fact not even my idea but it works. I like to build saws that run well using available off-the-shelf parts and are reliable. I also build Husqvarna CP 55s using a Stihl 028S piston that work quite well.

Think I will try a build next inspired by your information.. :)

Huztl build as I just did with 064 piston, no base gasket, but add enough back to get to .020in.
Bring the intake timing to 79 btdc. (Die grinder)
Blend a XT carb.
DO one of my muffler mods. Match the exhaust port/gasket/muffler

All this to see if I can match or even beat a stocker with a Huztl saw.
