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 The previous version was outdated and no longer supported.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

Advice on valve adjustment, close to spec at 5k, going on a 6k journey

Hey guys, I posted another thread informing i will be going on a 6k mile trek across USA.
I decided to do my valve clearance check early at 5k because i am leaving July 2nd.
this is what I have found,
intake: right @ somewhere between .010-.011 .011 is a little tight, .010 is a little loose.
intake: left @ nearly the exact as right

exhaust: right @.016
exhaust: left @ again .016 is a little tight and .015 is a little loose

I would like to hear some opinions as to wether i should bother getting the pucks out and shaving them down any?

The trek is 6k miles and after 5k the tolerance has seemingly stayed close to the looser end of spec assuming that from the factory they were either at the loosest end of spec or near to what I am finding them at now I THINK it will be ok until i get back home.

Opinions?
 
Don't worry about it. You'll be fine. These things hardly wear at all !
Valve adjustment is not needed very often with the 650 Rotax designed engines.
 
You'll be fine. Check it when you get back and report your numbers. I'll bet they won't be much different, if at all.
 
My advice is a little different. I agree with Hasenpfeffer and Dutchgit. But, you already have it apart. Do it while you have the bike gutted.

The adjustment would be so minute...hmmm decisions
My only concern is that if i do dive in further I'm increasing my chances of flubbing something up with only a few days left to resolve whatever issue may arise. I have to install a new chain, tire, side racks, oil chance, spoke tension, install piaa light...and pack. I am leaning towards leaving well enough alone and pouring my time into the other tasks at hand.
I would imagine that from the factory they were not intentionally set to the loosest tolerance, they probably haven't moved since leaving the factory.
I did do the Pod mod early on so that may have saved the seats from getting chewed up and having a tighter tolerance like many people have experienced.

Unless someone feels strongly about adjusting them i think illl just let it ride. I know ill be doing this job again when I return either way, so dong it now may only prevent me from having to adjust quite as much next 6k.
 
I think you'd be best off concentrating on everything else you need to setup, particularly as you haven't got your racks and aux lights going yet. I'd be inclined to get that stuff sorted out, and then before you set off on your trip, load the bike up how you expect it to be loaded for the trip, and take it for a 50 mile shakedown ride, just to make sure everything remains where it should. Lights and luggage are the bits most likely to require some adjustment. Whenever I get a new bike or a new luggage system and even new aux lights, this is the first thing I do. Better to find out you need to make a fine adjustment to something the day before you leave rather than halfway through the first day on the road. Another thing I have learned is that once you have everything loaded a particular way that works, always load it the same way. I managed to break a rack halfway through a trip because I decided one day to tie something on slightly differently to the way I had been doing it beforehand, only to find that the change I made had put just enough extra strain on the rack to cause it to fatigue and start to tear.
 
Yep, sort it afterwards. It's not likely to change all that much over your trip. I'm thinking I might as well check mine when I seal up the air box for the 3D print filter holder, but I don't plan on adjusting it until this winter (est 13-15k miles by then) as I have a 5500 mile trip myself in August, then figure I'll continue to commute while the weather holds up.

I'd focus on the other bits as nev said. Use that extra time you save by repacking your bearings and giving everything an extra once over.
 
I've made it to L.A.!
The bike now has an intermittent check engine light and it has developed a very metallic clattering noise at midrange rpm under Wide open throttle, only under load (not in neutral).
I'm a bit concerned for my ride all the way up the PCH and back home with these issues.
I've contacted husqvarna and they are trying to arrange a field engineer to meet me to investigate the issue, apparently there are 0 dealerships in the area able to successfully use their scan tool to even read the CEL, every dealership I have spoke with claims they are having software issues or under new licensing have lost the ability to use the scanner. Any one experience this clattering noise or have an intermittent CEL ?
I should mention... I have the eruption and pod mod done on the bike. I can't see a reason that would effect the noise or light.

What kind of fuel you running, how long has it been since you changed plugs?
 
The highest octane I can find around here is 91.
I'm still running the stock plugs but I'm only at 8k miles.

I'd pop out the plugs and take a look.

Where was your last fill up? (brand) not all companies are equal, some use more ethanol and methanol than others. I like Chevron.

Also refrain from that rpm situation, be it gas or a loose part, it is not good to duplicate it.

Low oil pressure could do that I suppose, like a clogged filter, and you would get lights.
 
I have had a ping under full throttle. Back off the throttle and do not let it ping. The metallic ping you hear is pre ignition. I am in the greater LA area. The fuel sucks. I always use 91 octane or they call it supreme.

I want to try the EJK, Electronic Jet Kit, and try to add some full for full throttle. It might be running lean at fuel throttle.
