Hey Octane,
The heat shield does have a roof......... but it's pointing the wrong way. It effectively stops almost any air coming up. Its there to stop the air that comes through the radiator. The only problem with this set up is (IMHO) that the intakes face backwards and the airstream though the engine bay is going to go up right at that point. If you want lot's of air at ambient temperatures you'll have to suck it from in front of the bike. I've got a few ideas on how to do that (which are just ideas at the moment) and i'm going to try a couple out on my project bike.
The other problem is that the intakes are facing the rear, which causes a low pressure area in the intakes as air russhes by. This slows the intake speed. If you lose the tool tray and turn the intake top around that might help some.
Just a little ramble

If it ain't broke, don't fix it.

Hi Mike.
..they are all marked with a number.
It's small, but it's there.

would you need to rejet the carbs if you only did the cut away air filter housing modification (I really dislike fighting the tub w/snorkel & lid out the top of my shelter) and NOT installed a free flowing exhaust??octane wrote:This baby needs to breathe feeeeely

1978 from a previous member here - taking up space
my original '79 bought in '91 - replacing engine (eventually, maybe someday)

but I do recall others here having cut away the snorkel
so maybe they have experiences to relay.

I'm very much a newbie at the mechanical side, but can follow directions well. My questions are:
(1) What tools will I need to do this?
(2) Despite my (very) limited, would I be out of line in trying to do this on my own - following the great info found on Randakk's site and within this thread?
Thanks in advance!

My guess would be with Octane's info and Randak's video you would be able to do this with a Sear's tool kit and maybe a couple of things you might have to buy on the way.
I did mine without the fancy stuff but I've done a number of carbs in the past.
It would not want to be the very first mechanical job you ever did but if you are the average guy who changes his own oil and plugs it seems doable.
the nice part is you can ask questions here and folks will give you the benefit of their experience. I had a battle with the boots on installation and got some advice on techniques others had used.
The best thing is to know when to walk away from it as jobs often go better the next morning.

For the most part there are no real special tools to do the rebuild. You will need something to measure the float height. I picked up a small carpenters square with metric measurements on it that I use and it only cost a few dollars at ACE. After the rebuild you will need to get a synch done, and that requires gages or sticks to do.Mike_in_Nebraska wrote:I'm very much a newbie at the mechanical side, but can follow directions well.

If you can follow directions and pay attention to details then you can do the job. The more "anal" you are about cleanliness and paying attention to the process the better your product will be. My first time took me about 13-14 hours. It was painful but very worth it.

WOW!!!! I never deamed they could cram so many pieces in such a small package!!! You mention bead blasting.... I am sure everone relizes the EXTREME care that must be taken to get all the abrasives out!!!! I have found a great way to "imitate" a comercial parts jet-washer, I run the parts thru my household dishwasher (note: my signature saying). It also works to clean carbon off of pistons!!!! I use zip-ties to hold small parts to the pegs for glasses and a closable mesh basket or mesh bag for really small parts. Make sure you have already degreased them to your best ability to start with. THANKS again for all the info, I would never have tried to pull my carbs myself without it.
It is easier to seek forgiveness than ask permission!!
