As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

What size jets should I get I have 122.5 mains and 42.5 pilots right now I dont really want to use the dyno jet kit cause of price and the fact that you cant go back. what sizes do you think I need? or mayb e just some suggestions for a starting main jet.

From what i've gathered the 42.5 pilots are probubly fine but the mains will need changing. so I was thinking maybe 127 for a start

the Exhaust is a 2+2 with baffles.

This is for my 81 GS850L

Thank you
Jake

I'd start with 130 and then come down until you're happy. I'd also run 43 or 44 on the pilot, or shim the needles...probably going to have to shim the needle anyway...
 
rule of thumb for main jets is 10 to 15 percent bigger than stock. The main jet is for 7 to9 thousand rpms, for mid range adjust your needle clip up one notch to richen. This is for the mid range throttle, about 5 to 7 thousand rpm. Pilots might be able to be left alone. I hope this can get you started on your persuit to an awesome torque curve

quick stupid question how can I go about removing the needle. how do I get the little clip out? do I need a tool cause I cant think of a way to get it out.
 
you will need a long tipped snapring pliers to get the C-clip out to remove the needles. Also If memory serves me #2 washers from the local hardwhare store are the right ID and OD to use as shims for the neeldes.

Just as a side note the Dynajet needles have a much more radical taper than the stock needles.
 
a ... if you can possibly afford it get the dj kit, it saves much aggravation. i tried the shim method with my 1100, i just couldn't get the needle rich enough with k&n pods.

2 .... i modified a set of needle nose with a bench grinder to remove the snap rings, as i didn't have the proper tool.
