i have new spark plugs, but no new wires (im kind of hoping that the plugs aren't firing as hot as they should). i have cleaned, and re-cleaned the carbs, re jetted them, new air filter, new exhaust... so is this an ignition problem, a motor issue thats over my head, some simple solution that will take 0 money and 2 mins of my time (<-- putting my money on the last one) please help!

if its cold, forget it
I have a 1978 gs 750 I've sunk a LOT of time and money into. i got it running fairly well but am still having a few issues. If the bike is cold it almost begs for ether. i have to choke it every time and kick it off 100 times before it starts to fire, and it takes me revving it choked for 10 mins for it not to die.(i no longer have a electric start so im kicking it off and its exhausting). after i get it started it runs fine... unless its at night and/or just a TINY bit chilly, then its starts spitting, sputtering, backfiring, and almost seems to bog down when i hit the throttle and just losing power. (more spitting and sputtering than bogging down)

What's the voltage at your coils?

yeah, check ignition timing and make sure your carbs are sync'd and give the screw settings a once-over. I had a Honda that wouldn't start when cold and sputtered a lot because it ran on 3 cylinders with the choke on, and syncing the carbs completely fixed the problem. Also, there are 4 little fingers on the choke rod that lift the plungers. When I got my '79, one of the fingers had come loose, so the choke on that carb wasn't actuating. Pretty easy thing to check and fix, if by chance that's the problem.

Do you remember your thread way back in October when Basscliff gave you the mega-welcome? Go back and read through his site and you'll find the instructions you need.

Just some math and a little wrenching....and cleaning the old valve cover gasket off, which to me, is the worst part.
Have you used the search feature ? It's very helpful for finding answers to questions you may have. Of course, don't hesitate to ask if you need to.Larry D

Arghhhh! I have said this time and time again. Get rid of the points and condenser ignition!! There are very good modern replacements out there that are set and forget, why do people want to stick with antiquated garbage??

I've learned (am learning) the hard way that not listening to the advice given freely when asked for leads to many many more problems that would have been resolved the first time. I just hate to see people continue having issues because they didn't bother to make the effort to try especially knowing the problems could have been resolved sooner had they.Cowboy Up or Quit. - Run Free Lou and Rest in Peace
