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 The previous version was outdated and no longer supported.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

Dellorto problem

I'm posting this here instead of 610 DS forum, as most 610's are later model with Keihin.

Carb on 610E is still over flowing float bowl when assembled. It has been carefully cleaned and reassembled, a new needle and seat kit installed. We have tried all sorts of float heights and float tang and pivot seem to work fine. right side up and upside down, you can shut fuel off with light pressure. Floats move up and down freely, "float" in gas and when removed have no gas in them. Our only guess now is that pins on floats are worn or distorted by ethanol gas. Anyone have any thoughts?
 
It's a Dellorto right? Where and how much is it leaking? Mine drips a little from one of the overflow lines. I've messed with all of the stuff you mentioned with no effect also. After looking at the guide (can be found in another post on this forum) I'm wondering if it's caused by the choke leaking?
 
Perhaps there is a siphon going on in the vent tubes. Your post sounds like what I went through with my 1988 510. I still have a briggs and stratton rubber tipped needle in it and a virtually new nedle or needle and seat in my jet box. In my instance if the bike becomes horizontal often it leaks continiously out an overflow tube but laying it over to the opposite side cures it. Once I figured out how to do that I never looked further to see if a different cure could be figured out. Not sure if that helps, I rode a 1999 410 for a while and it never acted that way.

I had a couple of old 510s with carb issues. One bike the would do exactly as you describe and the only thing that made it not run fuel out after dissassembly was to reassemble it upside down
(I am not kidding). The other problem was fuel running out the overflow after a crash and this could be stopped by turning the choke on and off. The bikes always started easy and ran great other than these oddities! Hope this helps.
 
Not sure if this will help.. Remove carb from the bike remove, the bowl and just check the floats are not fowling inside. Remove all the fuel from the carb. place fuel line on to carb. now whilst you have it you hand blow thru the fuel line.. now whilst blowing thru the line, turn carb slowly up side down. When the carb is inverted there should be no leakage, you shpoul;d not be able to blow [past the seat.. If there is go back and check float height and or needle and seat.. If not.. fill er up. Before you put the carb back on run fuel thru it this is a lot easier than time wasting installation and removal...
