Quote from: mercdude63No, i put in the extra plug they gave me. I think it runs better like that... but not 100% sure.

I tried adjusting mixture screw to 3.5turns out and it won't hardly idle without help... couldn't even get the bike on the road to find out if that's the problem. I shouldn't have to adjust the idle speed after the rejet, right?


OK if you have both the restrictors in... I think it might be raising too slow... making the rpm not want to climb at all when you give gas. What is it doing...
Cool.

Hey mercdude...
I said too slow when both are in...
Cool.

Quote from: seshadri_srinathOK I have one set of carbs lying in my house with the same damn issue...
OK his issue is the opposite... he's got both holes with the correctors...
This is the reason yours is falling on its face...
The drill you used was too big... yes I know DJ supplies it and yes they give you a tap as well... and plastic plugs... but a stock slide can be fixed to have 1 hole shut, by tapping it with a 4-40 machine thread and using a nylon 4-40 screw. that 10-24 they supplied it huuuuuuuge, once you take the plug off you have a monstrous hole .. 2-3 times the diamater of stock... now... flow through a orifice/pipe... is not exactly dependent on Cross section area... which will be square of the radius.. its like square or third power or some funky math of the CSA... ergo... double the hole diamater and your flow rate is now like 16 times or more... Hence... My solution ... I am going to start drilling the constrictor... start with a 1/16 drill, and maybe go 3/32's or something... Taking it out and leaving that huge hole = very bad...
Hell I a almost tempted to start offering a regular jetting service... I cant believe 2 people in the same week did the same mistake... and BTW totally idiotic on DJ's part... stoopid people. they started out having those needles so you can jet a bike wihtout taking off the carbs... and they added more and more shaZam! to it to acheive that goal... its screwed up beyond repair now.
Cool.
Srinath.

This was when both were open... and one was drilled and tapped and the plastic plug removed.
Cool.
Srinath.
