Bike has Ricky Bobby syndrome

If you didn't know I had my bike ready to be parted out...all stripped down.  This and that happend and all the parts sat in boxes.  Well I finally got my life back in order and after a nudge from my brother I basically rebuilt the bike.  Had my first ride in 3 years 2 days ago....man it feels good again  :cheers:

Anyway,  while cleaning the carbs I saw some 'crap' on the pilot jet to the left carb and still put it back together figuring maybe running some fuel through it would clean it out ( I tried carb cleaner but it just blew everywhere and not through the jet).  So I got it all insured/registered again, bunch of new consumables tires,brakes,chain, etc... Started it up and it lopped around on the right cylinder for a minute or so until the left cylinder came up.  Let it warm up some more and got good response to blipping the throttle so I took off around the neighborhood.  Cruising around at 3-4k 25mph all is good.  Head to the gas station babying it and fill it up.  (ahh full tank of gas <$15)  On the way back home at around 45mph 5k rpm I get a gust of headwind and the bike acts like its starving for fuel (no throttle change).  So naturally I assume its a fuel issue and switch to prime and roll off the throttle some to give it a chance to 'refuel.'  After the rpms drop some it comes back to life.  Accelerating back to 45mph it does it again... :mad:  but this time I give 'er WOT and it takes off Woooohooo!   :thumb:          Today I took it out and if I'm not 'going fast' it doesn't like me  :icon_twisted:

Simple rejet should fix it but I'm waiting for a lunchbox to see how much leaner its going to get...or I should get off my ass and design a EFI system for it.  Still wondering how a low pressure port injection system would work for the ol GS.

I mentioned how much I hate messing with carbs.  Let me know if you ever get off your ass and get FI working.  I think the only downside is mentioned here!

I got GSXR FI sitting in my gar, and guess what, its not going to be easier than messing with carbs, waaaaaay waaaaaay harder, to get it right not only you have to be an electronical genius (jeffD certainly has the credentials on that, as does starwalt ... but I cant think of many others on this site) you also have to know carburetion really really well. Ironically, if you do know carburetion that well, you will gladly deal with those over FI ... only way is, if someone made a drop in kit with all the mods made ... I am guessing suzuki will sometime in future and we'll be scrambling to slap it on the bike.
BTW someone I know converted their vulcan drifter some or other to carburetion, and the guy and the repair shop guy were saying how much better it worked ... FI is greatly inferior to carburetion atleast for how it performs. And dont even get started on how much harder they are to maintain. Most bikes have problems due to extended neglect ... FI is worse ... and far more delicate and does not have easiy and cheap replaceable parts ... touch it and it will be 500 bucks.
Cool.
