Huzo, Thanks for all that info. Now I need to decipher and figure out everything you said. LOL... I have the service manual and perhaps it's me, but I think it leaves a lot to be desired..
I have bumped “The New Improved Guzzidiag Tutorial”Don’t even think you’re going to get a handle on it for ages, but you will.For the record, your bike has the W5AM ECU.DO NOT read anything about any other ECU, you’ll just end up in the ****.Ask any question you like, because 85% of the people reading your post (including me), will say to themselves…“Actually I was wondering that too…”No one will put you down.Bloody Beetle is a freaking genius, but really has gotten this thing to the stage where mortals can handle it without blowing their bloody hands off…..(mostly).
Software: Guzzidiag, free but donations accepted. Will run on Mac, but you may have to fiddle with it.Cables to connect laptop to bike: Lonelec in England. About $40 or so. Amazon has cables as well, but the Lonelec is recommended.TB balance: I like the vacuum gauges.

There's a pdf of throttle body balance on the griso.org site.https://www.griso.org/CARC_TB_Balance.pdf
Tks very much for that link and reminder to recheck the TPS again after adjusting it.On my CARC Griso doing it on the computer that part was a breeze,,,,On my CalVin, rechecking and resetting the TPS manually,,, it was a finicky AF pita, it kept moving around tightening the screws
CX - THANKS! That really brings understanding home with the file with pictures! Brilliant. I am getting a faint understanding now of what not to touch, even as I cannot see it underneath the tupperware. Thanks!!!!
Everyone says to close off the idle screws before balancing the throttle bodies at 3000 RPM, but IMHO the idle screws are not letting much air in. Just crank it up to 3k and adjust the screw with the spring on the left side until the vacuum on both ports are equal. Easy as pie.
Just that it works
Another thing Sempy…If you do your TB’s and balance before you’ve really gotten a solid grasp, even if it’s perfect you’ll ride off down the road with a gnawing sense of wonder what it would have been like if a proven expert had done it.You’ll not know if it’s as good as it could have been..(even if it is).Hence why I think it’s better to spend your initial hours, doing what is totally within your grasp while you’re studying up on the Beetle stuff. A slightly mal adjusted set of TB’s will not actually harm your bike, but if the pinion nut comes loose, it’ll look like this..For the record, that’s less than perfect…Greasing the swingarm pivot races and the drive splines is a vastly more pressing issue.
HUZO, What is the Pinion nut you are speaking about? Something in the shaft? Remember I am a new guy here. Thanks.
Ok, I’ll let better heads than mine comment on Guzzidiag, but sounds like you’ve done well.I would let the steering g head bearings go without a worry, because even if they are shagged, it won’t hurt the bike.As for the CARC, of course it’s up to you, but I can tell you that mine was perfect at the start of the I’ll fated ride, and 400 km later, was screaming like a stuck pig…!If the nut backs off for whatever reason, the damage will be immediate. However in the interests of balance, mine did 194,000 before it happened.It’s like I said before…“Ya’ gotta’ ask yourselfDo ya’ feel lucky…Well do ya’…”
*Is a TBS via Guzzidiag the same as Throttle Body balance? If Throttle Body balance is needed manually then I need a set of carbsticks also then.
