1978 GS1000 Daily
Hello folks thanks for stopping by. My wife inherited a 1978 GS1000 that has had all distinguishing body panels removed and discarded somewhere in a junkyard. My wife has modified the rear of the frame and made the bike a hardtail with a springer seat instead(not to my liking but its hers). I told her that I'd do the powertrain work for her so she could focus on making it cool/pretty/ratty or whatever she wants. Her end goal is to have a unique daily motorcycle that she can leave out in the heat of the day and not worry about the desert destroying her expensive Ducati that's garage kept.
On to my task, powertrain. Currently the bike has OEM sized jets(95 main 15 pilot) in the carbs, some mismatched set of needles and new K&N oval pod filters for fuel. Exhaust is OEM head pipes to two mufflers off some newer motorcycle; 2-1 style exhausts. As you all know this isn't enough fuel for the amount of air it pulling in so I'm patiently waiting for my DynoJet kit to arrive which includes their 138 and 142 mains(130-132.5 Mikuni equivalent) and four matching needles to replace my Frankenstein set. I have on hand new 17.5 and 20 sized pilots incase I need to upsize those for any reason.
On to the current running condition. The bike moves under its own power, reluctantly. It idles well now that I've ditched the small cheap pods and installed the K&N pods instead. As far as screw adjustment: fuel screw 6 turns out, air screw: seated. I hope I got you got somewhat of a laugh out of that because I thought I was dreaming when the bike actually drove itself on those settings but this tells me there is not enough fuel getting to the engine just yet. I tried 1 turn fuel, 2 turns air and I couldn't even roll on the throttle without it bogging and turning off.
While i'm waiting for jets in the mail, I'm going to check valve lash as that is where everyone seems to point first, then timing, then air leaks THEN jets/carb adjustment. I've already emailed Steve and asked for his valve adjustment guide and I'm shopping for a new valve cover gasket as I'm typing. Suggestions, comments and criticism are welcome.
