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.

    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.

Found a set of what I believe are Megacycle cams 385-25 Intake and 385-X13 exhaust. Are these too much for a 10-1 1260 some street and weekly drag bike with a decently ported head and 1.5 OS Intake valves? http://www.megacyclecams.com/catalog/catalog.pdf Page 56. Guide clearance probably an issue, and hardfaced rockers at least for the Intake? Starting bid is $265
 
You will definitely need shorter valve guides & better springs. The welded rockers arms will help too but the valve spring pressure is what is harder on the chrome facing on stock rockers. I have used stock rockers on big cams but watched them closely & checked them after every weekend I raced.

those cams would be better in a 1150 casting or something bigger. consider a intake / or set of .348 lift cams - (aka drop ins) would really wake that head up and not have to do much to get the benefit.

Kind of what I thought. These were affordable, but after all the work to make them fit and live I am probably behind, and the project turns in to next year instead of this year. Here are a couple pics of what I'm up to.... Bandit forks and swingarm (2" longer than 1100), big brakes and modern tires, 190 out back. Not strictly dragbike but it should be plenty fun on and off the track. Lunchbox headlight and gauges going back on, looking for the sleeper vibe.

nice looking Bob. I would be happy to buy or trade certain parts off of it. the kick stand was moved to get more turning clearance on pizza cutters - but that huge tire out back changes all the rules.

I'm all settled in in a new city / and house - give me a holler I am finding gs performance stuff I forgot all about
 
Please post what you are doing to get a chain on it. I am going to be doing something similar to a 83 750E. Except I am using Bandit swinga , forks and motor. B12

Bandit 1200 hub (longer than GS), 2mm shim under 3/8 offset sprocket. That's it. I am going to check with a laser but it looks straight. I did razor blade off the sharp edge of the tire on the chain side but don't think I had to. Solved the rear brake pedal\linkage clearance with Gen1 Busa rearsets and some adapters hacked out of bar stock using only a $49 Harbor Freight drill press and a chop saw with a 100 tooth aluminum blade. I need to take the swingarm off one more time to put on the plastic chain slap guard thingy. And I needed to saw off the monoshock mount or the battery won't fit. Good clearance for the Bandit brake stay as well
