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 The previous version was outdated and no longer supported.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

I have a 07 SMR510. About 6 weeks ago I got a container of VP U4..filled the tank up rode a few miles and put the bike away....A week later I go to start it up and its leaking fuel out of the vent hoses...Come to find out this stuff is notorious for gumming up...So I drain out all the fuel and the bike has sat up until yesterday....Take the carb off give it a good cleaning with carb cleaner. Removed the fuel screw ( forgot to count how many turns it was out, lose the spring, oring and washer). Talk about a good time...

Today I find everything and put it back together...
Bike seems to be having a small issue with firing up...takes a good 3-5 seconds.
Once the bike fires up and I blip the throttle the rpms come down to idle level pretty fast.....when i go to blip the throttle again it goes pop and dies....

So, Ive looked around for adjusting the carb and I cant seem to find anything....

Can anyone give me any tips to get this thing figured out.
How are the adjusting nuts supposed to be on the carb and up by the throttle? How much slack needs to be in the cable if any...

Coffee is local and helped me out with the jetting so its pretty much dead on where it needs to be. Its just the other little stuff I need help with.
Thanks

Fixed it.....Air compressors are your friend. Took everything back apart and blew the carb out. A piece of the orig fuel screw oring came off and lodged itself in the circuit...fired right up after.....Rookie mistake.
 
So now I just need to get the AP all figured out, or at least fine tune everything. Theres a slight bog as soon as I twist the throttle. Bikes died 2 times on me riding, both times coming to a stop with the clutch in. with the hot start out, didnt want to fire up right away.....
Thanks
 
Regarding the stalling it sounds like you are rich on your pilot circuit. Adjust the fuel screw for max rpms at idle. Keep turning the idle speed down as you adjust the fuel screw and watch the rpms on the speedometer... that should make the AP behave better too.

Unless you have changed something you should have the correct jets in the bike.
 
mine cough stalls if i forget to put hot start back in after firing up when ive stalled/dropped it in the forest etc.
