    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.

if I wanted to rebuild my 1982 1100E and upgrade 20-30 horsepower, which cams and compression ratio should I go with ? the gs world is new to me, I have been on the schnitz racing website looking at web camshafts, so that's all I'm familiar with. thanks for any info
 
To add that much HP, extensive modding will be needed. Welded crank, high flow head, big carbs, big bore pistons, high lift cams and matching springs/retainers, etc. Lots of $$.
 
Projects like that have been going on here for a long time. Sit back and search out some old build threads.

Unfortunately some of the nicest Bike/Build threads as well as the builders are no longer with us. Joe Whelen was one of the masters....

Thats an understatement ! Don't try this on a budget. You'll be disappointed. Plan on putting out 5-10 x what the bike is worth......​​

thanks guys , after reading hundreds or thousands of post I found this one . posted below. In my opinion , great numbers , now I wonder what kind of power it could make without the street porting ? and who could do the porting if need be ?

the last 1166 I did had 10 to 1 Wisecos, with .348 Web cams, street ported head with stock valves, 36 Mikuni RSs & a V&H pipe. It made 140 at the rear wheel. If has run 9.29 @ 147 with a slick & wheelie bars.

Don't forget the welded crank. Some '82's have them already, but there is no way to know without an inspection, and don't even think of running big HP without the welding.

I suspect you will get a good gain with the parts you listed, even without the porting. How much? I don't know. As I understand it, though, an 1150 head will flow better than a 1100 head, so it you come across one of those, it might be worth the spend.

BTW, Ray, who made the post above, was banned here by our admin Frank. Apparently, repeat cases of not delivering on paid for parts. I have no specific knowledge, beyond reading posts here and what Frank did, and he's not one to act in knee-jerk fashion.
 
Also, 'Rapid' Ray does most (if not all) his own work. So the $ is different for him.

With it being 40+ years old and you looking for higher performance, maybe consider something made in the last 20 years. There would be a lot of advantages. Economics, reliability, drivability​, parts availability to name a few.
