Any suggestions about the carbs It is a 1980 gs450 it starts will not rev up and it occasionally back fires through the carb

What have you done to it?

How long have you had it?

Have you read the stickies at the top of this forum?

You're not giving us anything to work with here

i had it for a few weeks motor was locked up if free it starts and all the carbs where rebuild seems like not getting enough gas too the engine

Backfiring through the intake is usually a timing issue.

It doesn't do it all the time tho when it start it will idle and it stalls almost like it has ran our of gas in the carbs then you have to wait for a few minutes then you can try to start it again

Could be petcock problem, try running it on prime and see if makes a difference. If carbs were not completely stripped down and soaked in Berryman's carb. cleaner or something like it, may still have some blocked jets. Check Basscliff's site for about anything you need to know to do proper cleaning, if you haven't done so. Also need to change O-rings inside them. Cycle O-rings are place to get them. Adjust valves, synch carbs. terrylee

My 78 gs 1000 is doing the same thing-Idles on choke way high-idles down w/choke off-won't take any throttle when u put it in gear-replaced petcock-cleaned and rebuilt carbs according to the book-getting really frustrated -if i can't fix soon i may set fire to it! lol

Before you set fire to it, send it my way.

No airbox, I would guess

Cleaned the carbs by what book?

Adjusted the valves?

Air box? Pods? no air cleaner?

Stock exhaust? Header?

Backfiring out of the carbs is a lean issue

Checked your timing as yet?

its running just have too adjust the carbs too keep it running when choke is off
