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 The previous version was outdated and no longer supported.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!

It is kind of an odd response.
I had to buy a r-0 needle jet because none of the bikes I got had one and some were supposed to come that way. The r-0 needle is as of yet untested. I have (on a six speed)the 430 cylinder and piston with a 500 head and a stock 430 exhaust from which that cylinder and piston came off an auto. I have the needle (the one you put in the post 6DH20 ) in one of the extreme positions, I found it that way this spring and came to the conclusion (apparently same as before) after moving it around that was best. I think the leanest one. R-2 needle jet. Clearly there is much more empty space in the crank cavity (and the head difference) on the auto but it might count.
I also might note that I seem to have settled on the 3.0 slide or a 2.5 slide modified and re marked as 3.0 which has been discussed on here for that type of carburetor in probably a different model.
I never messed with my 86 430 auto just ran it like the guy I bought it from did.
My more advanced bike has the keihin pwk 39 which is pretty easy for me to figure out what does what with the available literature. I really don't know what to make of the fuel around here lately stuff from steel tanks on my brand x bikes seems to turn black.

My father set up his 1988 430 AE this way and never missed a beat. I don't know if it'll work for yours as it's an earlier model but I hope it helps.

I have put this tuning ( under) last week and it seems to work .
I think my R0 needle jet was too small.
Thanks
