    A note to old forum members...
    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...

    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.

thanks for lookin.

I have heard of this also but I don't know of anyone who has ever had it done. If we want 44s, we buy 44s.

I would forget the upgrades and just enjoy it the way it is.

My sentiments as well. Too many ifs involved in carb boring. Start from scratch with the jetting.

thanks for...

the input and advice guys.thats why im on here.
im more concerned with upgrading the suspension and brakes at the moment.the bike is already altered appearance wise.more of an old road race/madmax look.shortened the frame and tail section up so it ends at the rear axle.gonna drill the rotors.id like to change out the front calipers to four pots.i hear the zrx1100/1200 shocks are quite a good adaption.also putting on an aluminum swingarm.doctor says i have an acute case of "cant leave well enough alone disease"hey im a modifier not a restorer.its in the blood i guess.
 
I would reconsider the drilling of the brake rotors. I have heard many stories of rotors cracking because drilling them makes them weaker. My guess is that the material that the older rotors is made of is not able to handle the treatment.

We used to do quite a bit of that back before race carbs were available in different sizes. Don't need to do it anymore.
