    I receive numerous requests from people who can no longer log in because their accounts were deleted. 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.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

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.

K& N Filter Jetting/ 1982 650E

I bought this 650E about a year ago, as is. Came with K& N oval pod filters (two carbs per filter) and this had been a project for him he never got going. The carbs had 97.5 main jets (a check of the bwinger online service manual, thanks sir) verifys this is correct. PO gave me another set of jets and a bit to drill them that when measured was 1.12 on the micrometer, that basically makes them #110 jets, a bit more actually. He said he thought that's what would get the bike going. He said he was a member of GSR although I have never been able to find him on here or is basis for believing the bike would run correctly with this size jetting.

Does anyone have a better baseline with a standardish 4-2 exhaust system and the K& N filters? Bike falls flat above 4K rpm, starts, runs beautifully otherwise. Got to be some of you fellow GS riders that could direct me a bit. Thanks in Advance...Go Cubs!


PS Yes, I know I SHOULD get the airbox but want to give it a whirl this way first. I have a selection of motor bikes to ride in the mean time.
 
One week, no replys ?? Surely someone has this bike with pods...anyone?
 
Well, you had my attention till I read "Go Cub's" ha ha... I would not drill the main jet. If you start doing that pretty soon you'll have a bunch of main jets that you don't know what they are. Dialing in carbs can be time consuming and cost a few dollars for the jets. Personally I stay away from Dyno jet kits. I stay with genuine Mikuni jets. With your set up. I'd jump up three main jet sizes and go from there. So that would be 105's ... Let me check my collection, I may be able to help you out.
 
Get a Dynojet kit. Expensive but it will save you a lot of trial and error. This is well covered in the 1000's of posts about this subject in older threads.
 
Save yourself grief and opt for the dynojet kit... Otherwise you'll likely have poor mid range umph,and there's where you probably spend lots of time.
