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 The previous version was outdated and no longer supported.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

Noticed since I put my new gnarly n pc2 on that header part of pipe is a deep gold/bluing colour. Does this indicate its runnin a little lean/hot(down low id imagine)? Seems to feel hotter(pipe/engine) when riding slow tight stuff than used too but I hav been riding the 165 for the previous year more or less so used to that also. Seems to spit a little coolant when real slow goin so it's gettin hot-maybe 100ml at most so it's just below fins when checked cold post ride. Lectron pj set at 5/8-3/4 from seated(was 1/2 turn so richened a little). Forget what rods at around 49.5-50mm I think so was thinkin of goin half turn richer n if too much lean off 1/4 turn? Still spooges a bit out of cylinder/Pv cover/pipe when playing around but when ridden hard bugger all spooge
 
go rich until it four strokes then go lean until four stroking goes away. some golding is normal but why not know your jetting is right?
 
If the plug looks good I cant see there is a problem.
I have wondered for a long time how the likes of Jonny Walker ect manage to turn there pipes so blue and just came to the conclusion its because they ride so hard and fast, So stop worrying and just tell people its because your up there with the best :thumbsup:

dont worry johnny i tell everyone & anyone who will listen that im up there with the best(myself included)!:D plugs looks rich if anything as i richened up the PJ so its a dry(ish depending on how its been ridden) black colour generally unless doin a proper chop. yeah it doesnt look like the mxers pipes that are totally blue most the way round the header, not even as bad as JW in picture above. just a goldy header with a touch of blue/purple. running lectron. not sure i know what 4 stroking means justintendo:o but i might richen it half a turn & if too much ill just go back a 1/4 leaner. its nice & snappy off idle which is how i like it(wheelies like a demon) but just thought the bit of coolant being spat out & extra heat from engine when riding 1st gear snot or cuttin in trails may be slightly lean related?

ps- PC plat 2 pipe i had never blued at all but was running mikuni which was way rich then so probably why & what got me thinking
 
you need to look up the term "four stroking" its a term for when a 2 stroke runs rich it begins to fire every other time its supposed to instead of every time. its a key tool for tuning. try to avoid twist back and forth back and forth lean/rich lean/rich. the best, safe place for a two stroke to operate is right before its rich enough to four stroke, then you know its "rich enough". a tad leaner for crispness then thats it.

turn your powerjet richer quarter turn at a time, you will find the "four stroking"....then back it off....done.
i never look at the plug, only to change it once a year or so out of sympathy

Hows the weather over there, a dryer day can lean out your bike a little.
Lectrons tend to be forgiving in this department so just ruchen her up till she runs like crap bogs everywhere and is just rubbish then sneak up on leaning her till shes crisp n dry.
Personally i think richen her up half turn n leave it but im not there to hear the thing.

You dont want to seize another 165 dude!
 
This is 300 im talkin bout juicy. Bn runnin same settings since when you were here except for full fmf system now.

Stuck in bali atm no flights cos volcanoe ashcloud. Was meant to be home saturday but not looking good atm airport closed. Costin me a fortune. Travel insurance should cover a fair whack though still gotta pay upfront. Grrrr
 
Ffs man, get on a train no ash clouds gunna stuff that one up. That is if there is a train.

300 was sweet as when i was over, just go 1/4 turn richer an see how she behaves.
Good luck getting outta dodge!
 
Haha bali is an island of indonesia. Maybe tough findin a train that goes back to Oz! hopefully outta here today fingers crossed. Will go tad richa n c wat happens
 
Flying out in an hour & a half fingers crossed. Yes stealing a dodgy looking fishing boat was my next step! This extended holiday is cuttin into ridin time before i go back to work
 
Good luck. As long as the plane is properly stocked with adult beverages, it should make up for the extra wait.
