4500rpm idle when bike is level.

[wildbill]

Ok so im dumb. the throttle screw was set to much and thats why it would jump to 6k rpm. i adjusted it, put new o-rings in, re-cheked needle jets which were good but now a new problem.. i think this time it is vacuum related?

So i get the bike to warm up. set idle screw to 1200rpm once it warms up . its running while i tighten up the fairings. now i get on the bike, put sidestand up and now the bike is level. all of a sudden the bike jumps to idle at 4500rpm, i put the bike back on the sidestand and now it goes down to 3500rpm, level the bike back and up to 4500rpm again. Im not sure what this could mean, when i rejetted the carbs i made sure the floats were even which they were, my only guess it could be some vacuum leak? i dont know, any help would be great.

[The Buddha]

Throttle cable play is
Also check for vacuum leak ... yea.
Cool.

throttle is good. i was thinking i shimmed the needle wrong but guess not. my vacuum o-rings are starting to look worn, they both have a little chip in the side, i wonder if that could be it? Hopefully i can get similar o-rings at a hardware store.

[The Buddha]

Well, Vacuum O rings can cause it to rev high at idle. But 6K is a bit much even for that.
I am thinking you dont have the slides installed right ... the needles are crooked or somehitng ?
Anyway, If you dont find O rinhs I'll send you those for $2 (most of which is for the stamp on the envelope). Should have asked with the jets for a O ring set too. But anyway.
Cool.

So i went to Napa and got new orings. they have the same outer diamter, they are a little thicker on the ID but i dont think that will matter but as u can see from the 2nd two photos they are a little thicker, im just wondering if that will be a problem, im gonna put them in soon but just asking. Otherwise i will have to wait for new ones 

And yeah buddah, i didnt have the carb apart when i sent u $$ for the jetpack otherwise i woulda asked u for some, lol. last time i had the carbs apart in Nov 07 they were fine still, u can see now they are a bit chewed up. Im hoping this will fix my high idle problem, if not i will pull the jet needles out and give em a look. Maybe i did put them in back wrong, we will see.

[The Buddha]

If the O rings are just about thick enough that they will nicely squish into the thing and not pop the top open ... that will work well.
And 6K is high for air leak at that O ring. Somehting else is off.
Cool.

[The Buddha]

Level ... you think handle bar left or right makes a difference ...
If it does, once again ... throttle and choke cable need to have a bit of free play in them.
Cool.
Buddha.

[wildbill]

well i just wanted to make sure, sprayed wd40 around filter intake, carb top and bottom, nothin happened so i think im good on leaks. the choke i did not mess with when i took the carb out, just undid the spring, ill mess with the throttle some more and see what happens.

[The Buddha]

Dude ... you seem to be blindly fiddling with stuff here ... you can get the cable and spring in crooked and have the choke pulled on. ... more than likely choke ... may not be it, cos it tends to stay shut and un openable if you screw up.
Throttle OTOH ... easy to screw up and make it super duper tight. Turn the bars right ... idle goes up = cable too tight.
Cool.
Buddha.

[wildbill]

ok, everything is working now. made sure the cables had slack, works well now. took it out for a quick test ride and notice the can makes backfiring when i close the throttle. im prob running a little rich. should i close the air mix scew to say 2.5 out? what else maybe would help.. goin down one size on main jets?

[The Buddha]

No, you set your floats. Top of the bowl.
Remind me - Lunch box filter, so you running 150's right ... OK yea set your floats.
Also you need to be rich enough to run well on the coldest and humidest day of the year. And run acceptably on the hottest. Sitting up north where you are, I wont touch it till christmas day. But ... check/set floats, then post back.
Cool.
Buddha.

[wildbill]

floats are sitting a tiny bit above the gasket on both sides, so tells me with the u shape clear fuel line connected to bowl drain nozzle. still backfires when throttle is completely closed, other than that it runs well.

[The Buddha]

Tiny bit how much is that ... no more than 1mm is OK.
Backfire when shut throttle ... well, fix the real problems first, maybe you could richen air screw 1/4 turn is all else is good.
Cool.
Buddha.
