I have a '81 KZ440 LTD (belt driven) w/ 11k miles - starts and idles fine, however when you get past quarter throtle it bogs, and eventually will catch up (if it does not kill). I recently cleaned both carbs, where do you suggest that I start?
Thanks,

 

Secondary jets still have gunk in 'em.

 

OR, they are too big; too rich. Drop down a couple sizes on the 2ndary jets; i.e. make the hole smaller. Aftermarket pipe? (Usually a megaphone with no baffle, or something equally irritating.)

 

BTW, welcome to the forums, dad. Keep us posted on what you find. It sounds like the amount of air coming into the carbs can't keep up with the amount of fuel. At idle, they're fine, but as you mix more fuel, it gets too rich. Maybe drop the needles one notch.

 

JeffZX9- you hit the nail on the head with your first suggestion. thanks

 

I did all the carb work with both on the bike. Pulled the all jets/needles and not having to sync the carbs after my work.

 

jeff you da man!

 

Got lucky.

 

hahaha, right on fellas. Congrats.

Can we move this to the correct location now???? lol
