jetting help

kz1000 with yoshi cams pods mikuni rs34 pods v&h sidewinder throttle is very mushy and does not rev wont idle to well pilot is a 25 main is a 130 and needle is raised 1 i think im too rich because when i rev it it shoots flames out the exhaust sometimes looking for where to go any experts

thanks in advance andrew

did you just install all this stuff recently? ie.. the cams sounds like you firing too late. i could be all wet but check your timing

Yeah, I agree. Double check your timing. Pull a plug and see how it's burning.

i had the cam prob last year so i know thats correct im pulling plugs today im pretty sure im to rich but dont know how much how many jet sizes should u jump at a time and are the mains in 5 increments or 2.5

thanks for the help
andrew

ok so i went down to a 120 main and droped the needle to the mid position and it really helped but i have a wicked bog the bike almost shuts off if i snap the throttle form just open to full then the bike launches hard is this a sign of rich or lean?

andrew - I think it's important to make one change at a time when adjusting carbs. Making two adjustments makes it harder to pinpoint the trouble area.

How does it pull at wot? If it pulls good and doesn't bog or cut out at wot then your main jet is probably close.

Now onto the midrange - you didn't really say where the jet needle was set initially. Let us know where is was at (positions usually count top to bottom 1-2-3-4-5), and where you moved it to. How is midrange performing (meaning from 1/4 to 3/4 throttle)? After reading your post again it sounds like you could be lean on the midrange, but get back and let us know the position.

needle is in the 3rd position it was in the 4th it pulls very well after the initial bog

So by putting it in the 3rd position you leaned midrange. Try setting back to #4 and even go #5 if you have to, see if that clears up your bog/flat spot.
