I can do that. however if you got DJ needles, it might totally ruin the way it runs ... You may be better off send ing me the carbs ... I'll do only what needs doing ... Labor $20 and only the stuff you need I'll buy or swap around. Yea shipping back and forth is gonna cost ya ... But a kit from me may not fix any of your problems ... now what are the problems you are having??
Cool.

Quote from: AlphaFire X5as well as speedometer misreadings.

How could jetting the engine affect the speedometer which reads off the front wheel?

That isn't what I said, nsp. I said SPROCKET changes affect speedometer readings. At least they do on the bikes I've done sprocket changes on.

O.K., I see you did say SPROCKET, I apologize.

Now, not to start an argument or anything, :) Allow me to change my question a little:

How could DOING ANYTHING to the engine (OR transmission OR back wheel) affect the speedometer which reads off the front wheel on the GS500? :dunno:

I thought Srinath had a good point until your response:
Quote from: seshadri_srinathNsp - good point ... but OK lets say for fun he meant Tach vs speedo correlation ...

Ok, I still don't know exactly what is in these carbs b/c the bikes been around the block. I got it and it wasn't running right. It has no power at all. I've been told that this bike should be able to ride a wheelie in second if you bounce and clutch it right, but the only way I can get it up is to dump it from a stand still. I also believe it has no top end. It stops pulling around 8k and never actually pulls very hard at all. I took the carbs apart to see what kind of jetting it had b/c it has a V&H pipe and a K&N filter on it. I know you have to jet it, but when I took the bowls off the bottom, it had 122's in it. I don't know what size the others are. I was told it had all the jet work done right b4 I got it. The needles look stock. The only thing that looks new at all is the main jets. I took the plugs out to see how it was running and it's super lean on one side, and fouling on the other. I tried to swap the coils and wires and there was no difference in the way the plugs looked when I pulled them. I don't want to get ripped off by DJ, I just want the bike to run right. When I pulled the cam cover off, the main caps were broken in half. I'd never seen anything like that b4 in my life.

Well, I was wrong. On the GS, changing the sprockets won't make a difference on speedo readings. However, on the last bike I did a sprocket change on, a Yamaha FZ1, the speedometer is calculated from a sensor on the counter sprocket (the one I changed), hence having a speedometer misreading with a change in sprocket size. We had to install a sensor that would correct the change in speeds.

OK cam caps were broken in 1/2 ... what you mean caps ... the bike cannot even be run if its one of those things that hold the cam shafts down ... the cam shaft will fly all over the place ...
Carbs - Send it to me, if you've not cancelled on your DJ kit send it out with it. You dont look like you have a clue, I dont know how to transmit the visuals and knowledge over the internet ... might as well ...
BTW send a pic of the caps you say are broken. I am afraid to even guess
...
Cool.

Quote from: fat_sacHere's the pic of the caps.


OK then ... youre fu*ked ... that is horrible ... cam end caps are really what keep the cam shafts from getting torn up ... they maintain a film of oil and that keeps it from making metal contact ...
Yank your cam shafts and see if the bearing layers are scored/galled ... the ends of the cam shafts too ... so ... if that's the case ... 99% your head needs a new some or other ... cam bore maybe ... who knows ... new head OK ...
And it may be the reason your bike runs like sheite ...
Cool.

Not good. You need a new head. Cam caps are line bored to the head. I have tried to mix caps from other several heads and they do not line up.

Here is one on ebay:

#4 washer would not fit on mine, on the 04+, there should already be a washer under the needle, pulls yours and check.
