Problems Tuning Carbs

You wouls save yourself a ton of stress and agrivation if you purchased a repair manual. You can get them at repair manuals.com for less money than you have already spent on the bike.
 
we (or should I say he) has purchased the clymer manual. We are still awaiting its arrival.
 
hope this doesn't come across as insulting... i had the same problem with my gs650gl when i first got it and it turned out to be two switched spark plug wires. not to oversimplify, but maybe... :D
 
The jets are brass and cost 3-4$ each. The carb bodies are aluminum and cost $300 each. Steel would destroy the aluminum. Which one had you rather be replacing?

Ok I tore the carbs apart last night to discover what I believe is the source of my problems. The main jets were loose? all but one. The reason they are loose is that the threading was so corroded that when I tried to tighten one all the way it fell apart. So I ordered new jets and they are on the way, hopefully the stock size will work with my new pods form cycle recycle. If not then o well 16 more bucks for new jets?damn it. My question is why the #%#@ do they make these things out of brass? Why not steal or something at least a little stronger?

I can see the logic in that but, i dont understand how steel would damage the carb body. In my case the brittle parts that i feel could benefit from being made out of a stronger alloy are the main jet and the needle jet. The main jet screws into the needle jet. if both were steel i dont see how screwing them together would damage the carb body. Just a thought

O yeah and i actually got a price on the carb mainbody where i am, cause mine had a chip in it, and it was over $500 8O

I had been thinking about this, unfortunately there is no markings on the cables to be sure of which goes to where. But now that we have the Clymer Manual it will be one of the things that I will be checking for.

When this bike was purchased the electrical system was, to put it nicely, a mess. We have cleaned up most of it and now the electrics seem to run smoothly so now that the bike runs, consistantly, we are now trying to get its performance capabilities back.

GS pulls up next to a Gixxer...
GS looks over at the Gixxer and says "Who's your daddy."
Gixxer peels out leaving the GS in its dust.
GS says "What? I am its daddy!"

bad joke I know I know... but stolen (the good ones are) :evil:
 
Brass jets can get gunked up and be difficult to remove, but they do not rust or corrode bonding themselves to the aluminum as steel would.
If you had a frozen steel jet that had bonded to the aluminum, you would ream out the aluminm walls of the carbs trying to unscrew the jet.
When installing jets, there is no reason to install them any tighter than you can using only two fingers on the screwdriver. A good "finger tight" is plenty.
