Howdy,
OMG! where did you get that junk. I still say that they're coming from the same place. I know you say they look different. It might be possible that they have different production lines but, they're fairly small as far manufacturers go so I really don't think so. I know when I drag the numbers out, people don't believe it, or say they don't tell the whole story. I agree with that but, I think the error percentage is small. We keep a good record of these numbers so we can judge viability by product performance. I believe our equivalent for the kit tested would be the CKN 066. For 2012 we sold 361 with 3 returns. Does this mean we recorded every single one that crashed?, of course not. But, I do think that when our customer has at least a Benjamin tied up, and they don't think it's their fault, pretty good chance a large percentage is going to let us know. There are others that claim we're out of touch with our product but, when we run our $30 labor special for a AM cylinder replacements, we literally install 100's of NWP kits over a 3, or 4 month period. These saws come from all over the country, and, I would imagine they get run through just about every wringer out there. We use all the parts that come with the kit, 50:1 mix, stick in the test log, and run it like we own it. I know everybody has their own way, and I'm not saying they're wrong, I'm just saying what works well for us.
Regards
Gregg
 
Thanks for doing a test like this, Wiggs!!

It's good to know that these things aren't plug and play. I've been considering these kits as a cheap bolt on for some saws, but I guess they need some lovin' first.... Time is money in my world, so if you have to "massage" these things before you can run them, the point of the low cost is lost.

Howdy,

Glad you like it. It's taken me a lot of years of pushing, pulling, and prodding on a shoestring budget to get to this point. No, they're not quite there yet but, we're getting closer all the time. If you have a stock bore kit there, and the exhaust port has been raised with a shortened piston, something is wrong. That set up was just for the big bores where the crankcase has random clearance issues with the piston. Doing it to a standard bore would cause you to lose displacement for no reason.

Wiggs.... Thanks for the test and honest review. This will go a long way to show that we want some changes to the kit.. Thanks for your time!

Randy... This is the toughest one to get right. I think Johns test of the 440 is going very well as are most of the others.

This thread will go back to the manufacturer for review and hopefully a correction to the product. AND I believe threads like this help us as a community force change.

These 066 Hyway cylinders are not for sale on the site any longer. If you have a Hyway 066 cylinder from me, please send me a PM.. I think this is the only one I let out.
 
Been following these threads since you became a sponsor.....uphill struggle most of the way....you have showed your metal in this thread..I don't have anything modern enough to use your products so have no dog in the fight.....but the way you handle yourself goes along way to form my opinion of you and your business practices.. You hit a bump on this one...and shut er down right then and there...rather than send more bad units out or argue that this was the exception...good for you...this is how progress is actually made..talk to the mgrs....show the pics.....takes time and money to make money...

Thanks for giving me the opportunity to review it. Really wish it hadn't hit the snag, but such is life.

When u give the manufacturer feedback, make sure to tell them, if they alter the roof shape, not to raise it any, if anything, lower it .020-.030 or so. And while we're on port timing, if the intake went up .050, it sure wouldn't hurt anything.

Thanks... I'm at a loss as to why this hasn't happened this way before AND I'm tired of hearing the same old song and dance.... Aftermarket parts are junk and always have been......... Your input matters if we ever plan to advance, today was a win in my book because of guys like Wigglesworth, TBone75 and all the others testing and documenting these.... I appreciate your input, honesty and time you've put into your projects. Wished there was something else I could reward you with, I can say THANK YOU :msp_smile:

Thank you Randy for trying your best to help all of us out ! The 440 kit is doing great so far !

Don't mean to hijack this thread , but I nee some opinions on this 372 BB jug I just got. The exhaust port looks a little flat ? :msp_scared: LOL
 
I sell OEM Husqvarna top end kits, a healthy expensive alternative to AM kits with no questions on quality...... :potstir: :givebeer:


Just adding my humor, carry on folks don't mind me :rock: Progress is the necessity to success :msp_wink:

Best way to go , but they cost as much as most used saws ! LOL Unless its a big saw . So here we are . LOL
 
Just picked up a pair of 6401's and one needs a handlebar. Looks like it got run over buy a truck :eek: Hope to get them pulled apart tomorrow night. It's been tough to keep up with work, busy busy up in a tree most days weather permitting. Just posting all the pics and those other interesting reading swap meet treads lol. Anyway, I think they both could use a BB top end. One turns over super weak compression and the other is yet unknown. The recoil will not grab :msp_ohmy: Team blue needs help. I'll do pics of the tear downs this time so you guys have something to laugh at. You will love the "see-threw" bar on one of them.

Hope the plug and play goes my way again. If so then they get the grind and other good things :hmm3grin2orange:

So what seems to be the conclusion here? Are the others ok?. just the 066 kit that is bad?
Click to expand...

Maybe just THAT particular 066 kit had an issue, but the roof shape of Tbones 372xp top end also had a questionable exhaust port roof. I've had a WP 066/660BB kit on my milling saw since 2008, with the grooved rings no less, and its been fine. Obviously they aren't all going to fail, and likely its just a small percentage that will. Observing the port shapes prior to assembling, and reshaping if necessary would be a good idea. The saw modders have made it apparent that changing port timing would be desireable.

Flat exhaust port roofs have been an ongoing problem with many AM cylinders for years. A lot of you guys are looking more closely at these kits for the first time. This is the same feedback I was giving several years ago. Maybe something will happen now with the increased visibility. As a rule, I generally don't raise exhaust ports. That's the only solution to fixing a flat roof. This is the single most important reason I've sworn off them in recent years. If you guys stay on them, hopefully these kits will someday be consistent and reliable. Keep at it:cheers:

If the cranks are both good make no mistake they are both going back together. I always wanted to pit a stock Makita 6400 series up against a stock aftermarket BB kit. I'll do a bone stock 6400 up and see if it can keep up with the off the shelf AM with no mods at all on them. Then do up a 6400 cylinder. I'd like to take progressive steps on both setups. Do some vids same bar and chain. Doing a muf mod and then later go back into the cylinders. I'll take them both to a job or two and the firewood pile. They will get pounded on a bit before leaving my stable to make damn sure they are right as rain. Who knows maybe they never leave and take up a new spot in the fleet.

You listening Randy? PM me. Time to see what you have to plug and play on these Mik's.
