  • 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 The previous version was outdated and no longer supported.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!

250-500cc How long are the bottom ends good for?

I am finally putting a new piston in my wr300 at 2500 ish miles from stock piston. My mechanic friend mentioned if I ever get to the point when needing bottom end work I should consider replacing the bike as that would cost serious money. Right now its an amazing bike. Dialed in completely and does everything that all the new bikes do. BUT- its hardly worth anything in value. So my question is at what point would I need to worry about crank and or bottom end issues?
 
Why would you say it's hardly worth anything? It depends on so many thing...

As to bottom end...it all depends man...all depends I was quoted $500 for the labor + parts
 
See this thread: http://www.cafehusky.com/threads/bottom-end-shelf-life.29841/ Ironically, in that thread you post and answer to some other guy asking the same question. :busted:

"Needing bottom end work" is really vague. Eventually, you'll need to replace the bottom end bearings. That's a bigger job than a top end, but it's not a big deal and not really that expensive. I'd hardly trash a bike because of that. Further down the road, you might need to replace a crank, but I think a properly cared for 300 will be so otherwise worn out by that point that it won't matter much anyway.

You're doing your first top end on your 2009 at 2500 miles. In another 4-5 years you can do the top end again (and maybe some bearings), and then again 4-5 years after that. At that point, it'll be 2022, and the bike might need bottom end work. :lol:

I replace the bottom main bearings and seals when I split the cases. I split the cases if the piston/cylinder came apart...or I want to change transmissions.

Replacing the main bearings is a long and delicate process, but it's not difficult, it will take a good 4-6 hours depending on if you have all the right tools and if you know what you're doing.

Replacing the big end bearing on the rod, I take the crank into a go cart shop, and they handle that work in no time. Last one I did that with was a KTM and it needed a bearing race pressed on as well. It was $40 for all the labor. But, unlike the KTMs the Huskies don't have a bearing race to press onto the crank, so the bearings are easy.
 
Oh ok. I have to remind myself my mechanic friend is extremly anal too-lol. He just was lecturing me. Add to that I know a guy who had his ktm 300 cases split and when all was said and done he spent around $800. So was being a little paranoid
 
As all the others have said it is a semi EZ half day job and you can do it yourself with a few tools. If it need the lower rod bearing many shops can do that and the rod kit should be under $200. At the most it should cost like $400 and you will have a new motor that will last another decade or more. Don't sweat it, EZ stuff.
 
I can do the case splitting and bearing removal, so the only part of labor I pay for is the actually pressing of the crank, which is 60 bucks well spent. I have pressed and balanced cranks, but it's a big pain in the :censored:.

Even if it did cost $800, wouldn't that be money well spent to guarantee a happy bottom end for another 5-10 years? I don't see an $800 job relegating a bike to the scrap heap. :excuseme:

And ask around as there is always someone with the skills and tools that will do it for beer and let you watch so you understand the simple process. Last one I did I think I traded a rear tire to Jake to do it. He has all the tools, has done it many times and is EZ for him. Good friends are important in life.

Kyle helped me sort my 250 suspension and I dont even know him personally. Thanks Kyle :D

- Heck you could pull it apart yourself and post picks and ask questions and we could walk you right through it. You have options other than scrapping a bike over a few crank bearings.
 
Guy in Belfair does it competently for $150-200. No big deal. Don't go looking for reasons to buy a new Beta. :busted:
 
Actually to clarify- I wouldn't get rid of the bike. Just relegate it to "backup" bike. But I like being cheap and ride the piss out if it next couple years.
