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 The previous version was outdated and no longer supported.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

125-200cc Top end interval for CR125?

I'm wondering what the moto guys are getting for top end intervals? Fast kids that are on the throttle constantly? 12-15 hours? More or less?
I know for offroading you can go considerably longer.
 
I did a piston/ring when I got my cylinder ported at 17 hours, but it looked pretty good (didn't mic it but I did save it as a backup) and I changed it because I was in there and just got a freshly ported cylinder so why not. I think I'll be using 30 hours as my mark next time. Unfortunately, my crank big end blew at 41 hours (piston put in at 17 hours still looks good but will be replaced again). Revving as you do for moto (saw your vid), do not be tempted to run leaner oil ratios than 32:1. I love this bike and am not put off by it, but it is the most fragile machine I've owned between the tank, radiators, crank, and plastics failures I've had.

Anyway, I think somewhere between 20-40 hours would be the minimum unless you have an extremely fast kid on your hands.
 
I was washing my bike and saw my right side radiator air scoop tab is broken. I did have a "low side" once. They are kind of fragile that way. My rm has been down every which way and stays together. I may eventually invest in a set of Chinese radiators...
I run 32:1 with motorex syn. / pump premium. Seems to keep everything pretty well lubed. I was a little lean on top, but bumped it to a 180 mj and it seems good. Thanks for the reply.
 
Sounds like you need radiator braces. It's the first thing I buy for all my huskys. Enduro engineering has a nice set up for $100. I have hit bushes,trees and wrecked all kinds of ways and my radiators have not bent.

That's the first time I've read someone call anything regarding the husky engine 'fragile'. Does anyone else you know have issues with the crank?

I was referring to the whole bike, I'd be glad to explain, but the crank certainly falls under that billing. Like I said, I still love the bike but have had to make some ridiculous purchases that are unacceptable for the low hours. If "modifying" the motor by having it ported caused a crank failure (??), a whole bunch of ya better start sweating! No, I think I just got the turd crank and gas tank, and the plastics and radiator are what they are. Hey, you win some, you loose some, I love this bike and have kicked ass on it, but with all the weak-ass failures I've had, THIS one has been "fragile" at best.

However, back to the OP, my top-end has been very durable both before and after the Modifying.
 
True. Kicking compression is 195, fairly high but not absurd. Perhaps it did contribute, but 41 hours (17 of them stock)? Guess we'll see how long she lasts with the pro-x rod kit, I'll probably keep this bike "forever" and will know as the hours log up.
