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.

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.

Degreeing my cams

Keith - while I believe your opinions on the effect of lobe centers on performance are valid, this topic started with Craig wanting to degree what I believe to be a set of Non-Factory cams, (though this has not yet been made completely clear). The manufacturers recommendations which I refer to are those of the cam manufacturer, not Suzuki. Somewhere on the face of this earth, somebody sat down and designed a non-stock cam with the profile he has selected. They ran it in an engine on a dyno and declared that "this is good, lets sell it". Before they came to this conclusion they spent many hours and dollars refining their camshaft to create good performance in a certain application. So my point is this: if this cam does not create the power band that Craig wants, he should probably look for different cams. Yes, minor shifts in the peak of the power band can be made by advancing or retarding the cam but, and I repeat myself, this cams ultimate total horsepower will be made in the "straight up" position designed by the manufacturer. The great value in degreeing the cams, as you have indicated, comes more from setting the cams accurately to the manufacturer's spec., than from shifting the power band up or down.

THe cams in question are "Web Cam" .348" lift , 257 degree Dur @ .050". They state that these cams are for "Hot street & strip big bore motors. Strong mid range and top end." I have not sopped there. I am also putting in a 1168 cc kit as I have 1.5 thou. tapper in my cylinders---time for a re-bore anyways. I believe that the crank is welded by the factory in these engines. THe head is to get a complete redo and I have not yet decided if I can aford to get it ported and polished. The ingition has been repladed with at Dyna 2000 which will give me some room to play with. I hope I have not gotten myself into a tuneing nightmare, however, I have access to a dyno which should help. I apprecieate all of the activity that my question has created. It is nice to have people with what appearts to be lots of experience in these bikes. If anyone makes it up to central Alberta, pleae let me know and I will show you some very nice roads!!
