low on power, flame out of exhaust on deceleration

[piresito]

so i opened up the top of the right carb the one with the black plug and found that there is two short springs in the slide instead of one long one.
this cant be right?

That's not two springs, that's one spring. The way it's particles are displaced may confuse you though...

yeah my buddy pointed out to me the two ends that are sharp looking means it broke! glad they are only 5 bucks!

[rexpepper651]

would these be the correct pilot jets for my 97?  http://www.partzilla.com/parts/detail/aftermarket/XP-4459739.html

That mystery tube on the petcock is the vacuum hose, and it should be connected to the left carb.  I'm not familiar enough with the 89-00 model tubing to tell you why there would be a 'T' connection on there though...

Only "T" is in fuel line, only a single vacuum hose to top inside of left carb.  From 89-99 Shop Manual:

[BockinBboy]

Yeah, that's what I thought Jack, thanks.  It looks like the 'T' he has is much too small to be the one for the fuel line that goes to each carb. 

If it were an '04+ I'd say the 'T' on a vacuum line goes to pair system and other to carb (IIRC, haha), but he definitely doesn't have that setup anyway... so this small 'T' on the vacuum line is a mystery to me... vacuum from petcock should go to left carb only on 89-00 models.

so sweet diagrams!  thank you! now the wonderful wait on parts 

[gsJack]

There is another "T" between the carbs at the top of the bowls for the bowl vent hose that runs back over and down behind the air box and vents to atmosphere.  This is important, can cause running problems at high speeds and/or with strong cross winds if not placed right.

 i got the one on the top of the carbs in the middle that has a T in it running down under the airbox and pointed at the ground. found the missing tube location for the frame petcock located on the right side of the carb on the clutch side of the bike.  getting closer! now its just the waiting game for ups to bring parts and vacation to end. thanks for all the help everyone! hopefully ill have success!


the weather has been so nice the last couple of weeks i wish i could of been out riding. been a long winter here!

haha thats totally going to be me!

The 'T' on top of the carbs that goes toward the airbox - That should be routed over the top of the airbox, and terminate between the airbox and battery = can't move, no kinks, and out of any wind = ideal routing and location.

fantastic! thanks! ill move it asap!

[BockinBboy]

Oh, one more thing on that - place it so that it goes to the side of the air box inlet - you don't want it going across the intake opening and restricting air flow there.  On newer models there is actually a clip for it to run on the right side of the top of the airbox, but I don't know if the older models included that.  It's just a little band thing that is screwed in with one of the filter screws on the right side - not completely necessary but it is helpful with routing and keeping it in place.

im just curious. if this tube was incorrectly placed like i have it. what kind of effect would it have on the bike?

[BockinBboy]

At speed, it would bog down, sometimes its enough that the bike shuts off.  A lot of folks who switch to a lunchbox filter (no airbox) have trouble with it.  Just a crosswind can be enough to bog the bike and shut it down if its exposed too much.

i think i know what youre talking about actually. i noticed my bike will like slow and speed back up in the slightest amount. not really noticeable by the mph but in the feeling while riding on the highway but this could also be due to the poor workmanship that was done prior to me owning it.

[rexpepper651]

well back from vacation  got my slide springs in the mail. got everything put in and i noticed my float bowls were on the wrong sides so switched those around so i looked at my main jet size and it says its a 122. now i dont know if they dynojet jets or not. according to the chart on wiki i need a 127.5 and a 40 pilot. i havent tried running the bike yet. still doing some other work on it. i had a picture on here of my old plugs and some said it was lean. so replacing the jets, adjust the mixture screw and then sync the carbs. and take her for a ride and then inspect the plugs. this all sound about right? oh and so i have needles with the c-clips which position would it go in? 3rd from the top?
