    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...

  • Returning Visitors

    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.

When it comes to picking cams I am lost. The bike is going to be strip/street so here are the details of the engine:

1395cc 11:1
Ported 1150 head
Oversize valves on stock seats.
Hard welded gsxr rockers
HD springs


I am looking at something in the .370 to .380 range.
 
Web 212 grinds. .370 lift & 256@ .050 duration. Not too much lift so it will be easy on valve springs but still make good power. Make sure you use a top end oiler & 750 oil pump gears! Ray.
 
HI RAY when you say use 750 oil pump gears ? what 750 what yrs thanks,
 
I run the .410/.380 CamMotion cams, 29.5/25 Ported head, with a 1198cc flat top pistons, 40mm RS Mukunis in my 85 GS1150 stock 61'' wheel base. Street/strip bike. I would just put a slider in and lower it when I drag raced it. It run good.
I like big cams and I can't deny them little cams just don't fly. :dancing:

Remember if you have hardweld rockers you need hard weld cams. You don't need the same size exhaust cam as intake exhaust cam should be at least .020 smaller than your intake cam this will help keep the low end power. Unless your running a big shot of NO2.

On my 1150 I used the stock rockers and stock oil pump gears with no topend oiler been in the bike 10 years with no damage. The key to longevity is proper seat pressure 45lbs is all you need
