My goldwing six, GL1500, has two carbs, both of which I recently painstakingly rebuilt, but NOW I have some bizarre problem, seemingly carb-related <but maybe not?>: it starts up just fine when cold or hot, but it runs lousy, with cold OR warm engine. When it's cold, just after starting, even with the choke all the way ‘on', when I twist the grip, even SUPER-slowly, it dies -immediately-. This is ‘still on the centerstand' here, I mean. When it's warmed up, still on the centerstand, it seems more like normal behavior, twist-grip-response-wise, but _only_ after the temp gauge is halfway up or more... by the way, took painstaking notes _and_ made drawing when dismantling carbs, so chances I put some jet or tiny hose 'back in the wrong place' are ZERO. The main problem is, when it's on the centerstand and I have the throttle lock 'on' (_or_ when I try driving any ‘set fixed speed' down the hiway), it WON'T maintain a steady RPM setting, on the centerstand OR the road.. Also, when starting up from ‘stone cold', with the choke even ‘full on', it flat out "dies stone dead immediately" when I twist the throttle, even when I twist it super-SUPER-slowly. And I mean _dead_crawl_ slowly here, too...before the carb overhaul, it was at _least_ ‘driveable' cold, with the choke on...now, it's nowhere NEAR driveable, cold, not even CLOSE.... When it's warmed up, though, and I try driving down the hiway, it runs up smoothly ‘thru the gears', just as strongly as it ever did, even up to 5000 RPM in 1st, 2nd, 3rd, and 4th, but when I try setting the throttle lock, on a long flat road (say in third or fourth, attempting a 2000, or 2500 or 3000 RPM steady cruise), it won't do it, or even do anything ‘close' to it - instead, it acts as if someone shuts the key OFF every three or four seconds out of five or so, roughly. Like it ‘just ran out of gas' every few seconds. frustrating. On the centerstand with the throttle lock on, at ‘locked ranges' in the like 2000 to 3000 RPM areas, it ‘varies up and down' every few seconds, too, dropping 500 RPM one second and speeding up 6 or 700 RPM a few seconds later, and on and on, minute after minute, same deal, from the same locked twist-grip setting (and the throttle lock works fine)...this is driving me NUTS. I know it's some ‘simple thing', but the " which simple thing is it?" bit is the main problem....is there _any_ possibility this is 'ignition related'? my guess is carbs, but not sure, at this point... The faster I try to go, in the higher gears, the worse it seems to get. It's not ‘breaking up', though; it's more like acting ‘fuel starved' or something. BTW, the air cleaner has JUST been cleaned, and the fuel filter is nowhere -near- being clogged, and today I tested the fuel pump output against factory ‘minimum specs' for delivery per minute and it near -doubles- that output....also, when I took off the fuel hose TO the carbs today, about 20 minutes -after- my last road test, there was -still- plenty of fuel pressure IN the fuel line, if that indicates anything. and, all six spark plugs were recently sandblasted lightly and gapped correctly. It idles just fine (after warmup). also, when the carbs were dismantled, the floats seemed to work fine, not sticking, and float levels are adjusted correctly in both carbs (used dial caliper). I don't own one of the special honda pilot screw wrenches (and tried everything else to get ‘em out; the heads on ‘em are ‘round with ONE flat side' plus they sit down inside a walled recess, so there's nothing to grip...) so I had to leave those two ‘in' (1 per carb) when I dismantled, soaked and later ‘blew out'all the carb passages, etc. the gasoline in it is only 3 wks or so old... got any ideas on this? How come when I ‘accelerate like a bat outta' hell' or 'just sit there idling' it runs great, but when I try ‘cruising' any set speed with a fixed throttle, it flat-out dies every other second or two....the faster I'm going down the hiway, attempting a steady cruise, the more time the 'on-off nuisance' factor seems to 'elect' to stay in the 'off' election it so favors. I'd sure -like- to hear from you carb experts regarding your ‘most likely culprits list' especially those factors 'easiest to check out' first. Thanks, bill, aka "mr non-steady cruiser"
