If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

I put k&n pods on my 81 gs650. went up 3 jet sizes and put 3 shims under each needle. runs ok but has a bog under acceleration like the slides aren't opening fast enough. My uncle said something about drilling the hole in the bottom of the slides bigger? If I spring for a dyno jet kit will it help my problem? Oh running stock exhaust right now but plan on swapping open universal mufflers on it this week.
 
Yes, a Dynojet kit will help, but in the meantime, I have to ask if you did it correctly. :eek:

When you put the three shims under the needle, what did you do with the thick plastic spacer above the clip? :-k

There is a spring that pushes the needle UP into position. Adding spacers under the clip will do nothing except increase the preload on the spring.
What you need to do is to remove the thick plastic spacer and replace it with spacers (washers) that are about half as thick so the needle will ride a bit higher.

ohh ok i put the washers under the clip.

As mentioned earlier, all that does is add preload to the spring.

You might not have to remove the carbs, just take the tops off (you will have to also loosen the throttle and "choke" cable brackets) and you can pull the slides.

removed plastic spacer and put two washers on top of the clip. Night and day difference. I'm gonna run it like this for a while or until money comes my way. thanks for the help
 
put on the open mufflers and went up to 120 mains and 3 turns out on the screws. after i just ride it around no wide open just cruising the plugs looked a little lean but not too bad. After I adjusted the mixture screws again and let it idle for a minute or two the plugs all look brown/tan. I want to drill the holes in the slides bigger tonight since I have to take the carbs back off to get to the timing chain tensioner. How big should I drill them? What size drill bit does the dynojet kit come with?
 
anybody know what size the drill bit in the kit is? All I can find is stuff for harleys and they say to drill to 1/8th but i know that's way to big
 
went ahead and bought the dyno jet kit last night. I'm really getting tired of messing with this thing and I just want to ride. SO once I getthat in hopefuly I'm about done with messing with the carbs
