• 4 Stroke Husqvarna Motorcycles Made In Italy - About 1989 to 2014
     TE = 4st Enduro & TC = 4st Cross

  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Highest Mileage TE/SMR 449 or 511

We did a lot more than a rebuild. Your new crank shaft flows over four times more oil than the stock one, which not only cools the rod bearing, but also the wrist pin, piston and cylinder walls. Coupled with your new Zipty oil mod, yes, your engine is going to last you a very long time.

I know Tinken, I was just trying to keep it short and sweet!:)

I think the zipty boys have more experience than anyone with this motor at the limits. Pretty sure this is well tested and understood.

Don't get me wrong I'm not saying it's not a good mod. I'm saying if the crank shares the same oil pump as the top end and now you have 4x the oil normally being diverted away before it reaches the "high pressure " oil sprayers" you will loose flow somewhere else. Now my second question : what's the highest miles on a ZipTy racing bike ? Everyone who spends there hard erned dollars on a bike has a right to get a answer from the horses mouth , right ? Everyone is a potential customer . Posing the question should not be a insult to credibility . .... Back to work ! :)

understood. Was simply point out that if someone knew the issues with diverting 4x oil flow it seems ZipTy would be those people.

I would think so but you never know . Be really easy to sell things to people who can't see.... Like Obama did lol JK , not really :)

I doubt anyone modifies cranks and oil passages for the fun of it and hope it all works out. Guessing it has been years and many cranks to offer something like this. My point is if you are going to trust anyone to do it those would be the right people and know what they are doing. Also not something you do thinking you are going to make money at it as not many people going to pull the crank out to modify it unless something has already gone wrong. Not sure why this is a point of contention. Seems they found an issue, addressed it, proved it and offering it to those that feel they need it.

You are being very defensive on my point of contention . I like some of ZipTy's mods. The truth is as the silent partner of ZipTy "Tinken" has said in other posts and from what I have heard from ZipTy over the phone before "Tinken " was even a member and from geoge at up-tite is that there were issues with the TQ , crank .... We know Ty is a believer and Tinken, threw his posts endorsing non motorcycle spec mobile 1 . The only way for a TQ to get 700f is for it to constantly slip really bad , that could be from running car oil mobile one. Also to mod your crank so it will cool the wrist pin bearing more sounds like a formula for hoter oil, I'm sure the engineers thought of the kind of temperatures that are created in the combustion chamber and engineered accordingly . I have seen no where near 300degree oil as Ty claims from Tinkens post, the only way I can see it getting that hot it by it soaking up the heat from the TQ and wrist pin bearing and the car spec 0-40w soaking up all the heat and making TQ slip. I have been keeping up on most of these important topics concerning our bikes since I bought one. I have heard the endorsement of oil additives and all kinds of stuff that has got us to where we are today and this is the first time I have heard of the crank mod. I'm quite curious to here more detail on the oil supply going into the modded crank. I'm a great debaiter so if we can get some more info on the modded crank that would be awesome ! If you want to drink up any mod a race team puts out than go for it . I don't like to be wrong with my money.
 
Not being defensive at all. I don't work at ZipTy or really know much about them. Was just making some simple points. If I was personally going to make mods like this thats where i would send it as they seem to have the most experience with these motors. Thats all. I have seen a lot of pictures with a lot of motors taken apart and studied from those guys. I will just leave it alone now.
 
I'm actually kind of interested too.. does the engine take more oil or reroute the priorities or...

I find any work to the engine fascinating as there are so many -moving parts-.. it's close to rocket science.:o

Yeah I was just asking the question BTW I like your products Kelly as well as all the sponsors here. I'm just stuck on how our bikes are so flawed and need clarification sometimes .
 
I am the most jaded SOB on the planet, and recently spent several hours at the Zipty shop - they know what they are doing, especially with regards to the 449/511 issues.

Rearwheelin - you are in Bakersfield, it is not that far to Zypty's shop from there. Go see the what they are talking about in person.

For *whatever* reason the members of this site seem to think that the Sponsors have an air of legitimacy. While I never thought it would be my job to pre-screen Sponsors in regards to how well they do what they do, I do try to pre-filter the Cafe Husky Sponsors in a few basic ways.

By flowing more oil threw the crank are you shorting the oil supply in another area of the engine ?
Click to expand...
No.
There are two Eaton oil pumps in the 449 engine. One that feeds oil into the pressurized pathways from the oil storage area and one that evacuates oil from the crankshaft area. One oil pump works very hard to feed the entire engine, while the other hardly gets any oil to feed back. The more oil that passes through the crankshaft from the mod, the more it is then fed back into the pressurized system. So to answer the question again, there is zero loss in oil flow from the main system and the crankshaft, rod bearing, wrist-pin and cylinder gets quadruple the cooling. How cool is that? :)

Randy, dude... This is some of the funniest bullshit I have seen you write to date. I got such a laugh out of reading this that I had to CC to Ty. :lol:
