fuel starvation/bad gas mileage

[Spyderman]

the intake boots do not have ports on them with which to synchronize the carbs like the 850. I'm wondering if the screws you can see near the boots is what you would remove to do said syncing.

yes that is exactly what there for
by the looks of them i would remove and replace them with allen head bolts so that they can be removed with ease when you need to sync the carbs which should be done on a regular basis
so removing those old beat up screws will be beneficial to you for future syncing of the carbs
it will be easier to remove them now with the carbs out you'll need an impact driver with the right sized bit to get them out
be sure to use those copper washers that are on the screws now with the new ones as they seal up the ports from intake leaks

grrrrrrrr...BikeBandit has "cross-shipped" my order. Apparently that means each part is coming from a different warehouse, so they may not even ship until April 8! Maybe I'll put it back together using the old airbox boots and see how it goes. I don't want to have to wait that long to start riding again, especially since we are supposed to have really nice weather this weekend!

On a different note, with regards to electrolytic rust removal, is it necessary that the charger have a specific amount of amps for it to work properly? One charger I have is 1.5 amps, the other is 2 amps. My dad might have one with a bit more huevos than that, the question is, will he let me borrow it for this purpose

That happened to me on my clutch cable. They said it would add 1-4 days, after a week they still didn't have it by them yet, I was sick of waiting and cancelled my order and ordered it through a local place. Should be here tomorrow

I dropped off the tank today to have the rust inside removed and then lined. I should have it back within a couple weeks. I hope by then I'll have the airbox boots. I'll have to order a new petcock too. Looks like there's a light at the end of the tunnel!

Yippee! The airbox boots arrived today. Installed same, got the carbs back in, throttle hooked up, new gas line attached, airbox screws back in, everything tightened up. Put the battery back in, along with the new battery cover and "bottle fitting" (that strap that holds the battery in) that were missing when I purchased this bike. So now I have to sit and wait for the tank to come back. Pardon me while I drool in anticipation Here are some more pictures of my progress:

Hi,

I'm wondering who will have their bike on the road first, you or me?

Nice work.


Thank you for your indulgence,

the trickiest part was getting the airbox lined up so I could get the screws back in. Again, I used my trusty mallet, using the handle for leverage to persuade it into the right place. It's a beautiful thing, being able to work on a machine like this. Nowadays, you get engineers with CAD stations (at least with cars), moving everything around virtually, "hey, the battery will fit here". Then the poor bastard/end user ends up having to bring it to a dealer because he can't work on it himself. I think anyone who designs mechanical things should be required to maintain one for a certain period afterward, then such things wouldn't happen.

tank still not back yet, and waiting on the new petcock. I'm praying that it will get here soon, as we had 2 days this past week in the 90's!! It's not nearly that warm now but still plenty warm enough to ride. I'm jonesin'!!

[davidduarte]

my order from Bikebandit with the new petcock has finally shipped!! I should have that in a few days. Now I just need that tank back, and this Friday would make 2 weeks. The shop told me it would take a week to 10 days, so I should have it back by the weekend! Woohoo!

[davidduarte]

the new petcock (along with some other small parts) arrived today! I just need that tank now!

[davidduarte]

here's the new petcock, with the old one for comparison:

perhaps one of the more technically savvy members could comment on this. The petcock is essentially a valve through which the fuel flows from tank to carbs, but it only flows when there is vacuum, right? That's what the other line on the petcock is for, to connect to a vacuum line on the carb.

Hi,

Yes, that's correct. I think you get your vacuum from the left carb, that nipple there on the outside. The other two nipples above the idle adjuster are for vent hoses.

Great thread, nice work!

EDIT: I just noticed your last post was a week ago. Did you move to a new section? Lemme check.


Thank you for your indulgence,

Nope, I'm still here in this section I got my tank back yesterday, I'll post some pics tonight. If I can, I'll go ahead and put it back on the bike tonight, but I have to wait for the liner to cure before I put gas in it.

[davidduarte]

The dumb things I do when I'm tired. I went to put the tank on last night, and tried to hook the line from the carbs to the vacuum port on the petcock, and from the vacuum port on the left carb to the gas line on the petcock So I'll have to stop somewhere to get a new vacuum line, as the gas line is too big.
