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 The previous version was outdated and no longer supported.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

OK, first I am a two stroke guy. I haven't owned a four stroke for over 25 years. Here is my dillema. I picked this bike up about a month ago. Motor has about 15 hours on it. I have rode it about 150 miles with no problems. Runs real well and have gotten used to it and have the bike pretty much dialed in for desert stuff. Some of my buds that have four strokers suggested I bump up the pilot jet since in was backfiring a little and they all thought it was a little lean. So I pull the thing apart and take out the 30 pilot jet and stuff in a 35 pilot jet. It now seems to start better but the exhuast is a little black just off idle. The biggest problem I have now is I have stalled it a couple of times (the dreaded cough) in my driveway after a 30 to 45 minute hard ride. I hit the button and it won't fire. Pull the compression release and run it through and it still won't fire. It runs the battery down and I'm done. Smells flooded. Let it set awhile (while battery is charging) and it will fire up after it cools down some. The starter motor is working properly. It didn't do this with the 30 pilot. Maybe I am too rich? The manual says it should have a 32.5 pilot in it. What do you all think. It has me baffeled. :banghead: BTW the plug looks good. Should I go back to the 30 pilot and live with it?
 
I used to have same bike....similar problems..setup for vet mx....call halls cycles...they have a fix...if I remember right...plugging off accellerator pump bleed hole????...they are jetting/suspension experts
 
'06 te510 here, Played with carb settings myself to stop the decel pop. by the time the popping stopped it was too rich, went back to standard settings (Jd jetting) and backed off low speed jet 1/2 to 1/4 turn richer. Still pops but not as much, Nature of the beast I think. Also twisting throttle while pushing start button = flooded engine... just sayin. Have not heard anything about plugging off accelerator pump bleed hole tho mmmm.......
 
So heres my update and thanks guys for the info. Put the 30 pilot back in the bike. The battery ended up being junk. Put a new battery in the thing and same thing. Won't turn over unless I use the compression release. My bro and I try and jump the starter and nothing. So I call Dan at Motoxotica and tell him I need a starter. He says it's not the starter as he has never sold one for a Husky, and sells me the automatic decrompression release cam as they wear out. Sure enough I pull the valve cover and the snap ring that holds the device had backed off and rendered it useless. I put the new part in with a new snap ring and "wholah" it fires up.

So I go riding on Saturday and do about 35 miles at a good clip and the thing stalls a couple of times IMO it shouldn't. I just think, oh well its hot. No prob. It's a stinkin four stroke.

Monday go out for a quick ride with my bro and of course I stop to wait for him and the dreaded cough again. I try and start this thing for 10+ minutes and finally it starts. I tell him I am leaving and heading home so we are not stopping again.

I go about a quarter mile and the thing starts coughing, popping, will barely run and finally stalls again. Another ten minutes cranking the damn thing and it fires. I tell him I am taking this dirt rode and going home about 3 miles away. On the smooth stuff the bike runs fine. Get in the choppy stuff it will barely run again. I make it home thinking it picked up something in the carb and was clogging a jet.

So pull of the tank and am getting ready to take the carb off. For some reason, I decide to check the spark plug. I touch the coil wire and the thing pops out of the cap. I am at this point WTF. The coil wire had broken off in the cap and was pretty close to a 1/2 inch away from the metal piece it was soldered into. Some how it was jumping the gap.

Put a new cap on the thing and now it runs great. I hope you all enjoyed reading this as I have a good sense of humor, thank God. But it did have my blood pressure up for a few.
