i havea 2006 street glide carb. it is ported polished 203 cams mikuni carb. when i bout it it had true dual rineharts i changed the slips to a hooker. the other day i was driving up a hill and got a throttle a little and i heard this chatter not consistant just when bike is lugging. any idea what it may be? i am thinking it is the jetting but any help would b greaty appreicated. when i put hookers on it popped through cabr once and awhile so i turned air screw in and that eliminated that problem . please let me kow what you think it could be-

 

was it alot of pinging under a load? it may also need to be rejetted

 

thats when it was doin it, thats the same thing i thought bought im new to working on harleys i came from the sport bike world its when its under load and you throttle hard on it

 

What kind of fuel are you running?

 

bp 93 octane thats what has been ran since the build of the bike

 

Is it a slight chatter at higher speed not so much when your floaring but when its been under a load for a spell or a lot of valve chattering all at once.... does that make sense?

 

no its only when in in town and in a higher gear just cruising and throttle hard on it, or at highway speeds 5 gear and throttle hard it does im pretty sure it just needs rejetting and a tune in

 

Ive been in the wrong gear before and the bike chugged making the valves chatter some....does that sound closer to what you mean

 

no its not the wrong gear the noise might be similar to what your heard though
