    bad valve or cracked head???

    Its an 82 gs 1100 e carbs were rebuilt with dinojet kit and #4 cylander had to be tuned rich just to get it to run. It runs ruff untill about 3000 rpm. Other three are fine. It blows back into the carb on #4. How hard is a head rebuild if it is not cracked? What heads might fit if it is cracked and where do I find one?

    Have you adjusted the valves?

    Adjusting carbs is the LAST item in the tuning process. Spitting back through a carb might be carb-related, but it can also be tight valves.

      Have the carbs been synced? I'd do that first, perhaps it's way off & that's why it's running rough.

      What mods did you do to warrant the Dynojet kit? Stage 1 or 3 ??

          Maybe before some other stuff, but carb sync is supposed to be done after valve adjustment.

          The question remains, ... have you adjusted the valves?

            Well, I meant look at that first before messing with the head...

            However, the valve adjust suggestion is right on.

                I hear Toyota makes reliable vehicles.

                Edit: you can download a repair manual for free off the internet (search out Basscliff's web site). You will also find a procedure to adjust the valves there. You bought a 28 year old vehicle that needs maintenance.

                  Hey, thats what I do for a living...Toyotas that is... Deyo, read thru a service manual.. They are on Basscliffs site and other places also... It is not hard to learn. Just measure twice and take your time... It is very theraputic in a Schizoid type of way...
