    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.

and another!

and another!

and another view....this one i will use to produce a rendering of what i plan on doing with the bike.....see the following post please
 
see here

ok so this is a quick and dirty photoshop rendering of my plans for this bike.

the rear cowl is made from layered and then vacuum bagged veneers, essentially bent plywood that you see on a lot of furniture (eames). with the vacuum bag system, i am able to get even clamping pressure during molding and thus a very nice bent plywood part with compound curves galore. the final or top veneer should be east indian rosewood if i can find enough of it, or well polished maple. im not quite sold on the color yet, im using some left over 2 part urethane from some previous school projects (prototypes of consumer product concepts) and this happened to be one of them.

the colors i have are this sort of navy blue, a bright lime (almost kawasaki) green, a roe (orange-ish pink) and i believe i have a pale blue and the same metallic green paint you see on new vw bugs. i will decide soon....


the overall shape of the piece might change of course due to the demands of the veneers, but this is the idea.
 
also, so i dont know if i said this before, but i got the bike running only to find that when shutting the engine off or sometimes stopping at stoplights i would see (hear and smell) gasoline momentarily purge from the overflow tubes on the carbs.

well i took those apart the other day, found that my float seats and almost completely unscrewed themselves and the floats were of course completely stuck. well i tightened those back up and readjusted the float height....i must have been WAAAAAY off on the float height because i changed it to 26mm as per the clymer manual's instruction and i must have been 10mm off previously. welll, now it seems the changes i made have screwed everything up. it was starting and idling and running just fine, with a few flat spots of course but now it will not idle or rev with the choke off....any ideas as to why this might be??? what do i need to do now?
 
Have you done the o-rings on the intake side of life yet? Also, you mention that the #2 carb seems to be the main issue with respect to the excess fuel...petcock? See if, when you pull the vacuume line for the petcock off the #2 cylinder, you have fuel dripping out of the line, with the petcock in the run position.
 
hey yeah, i did the oring change on the intake boots. i think the reason that the left bank of the carbs was leaking noticeably more was due to the fact that with the bike on its stand it was leaning to the left.

and like i said, the needle seats had almost completly unscrewed themselves, leaving the floats pressed as high (or low with the carbs upside down) as possible, allowing way to much fuel to enter. it would start leaking when the throttle closed and stop shortly after the engine stopped drawing vacuum on the petcock. thats the best way i can describe it.



actually, put in a full tank of gas today and started it up. looks like its running just fine, its at least got a solid idle when fully warmed up and with the choke off. havent taken it for a spin yet but i think it should be ok. my next step is to conduct the highest idle process to make sure the air screws are dialed in.

so, more or less, everything is ok with the carbs now.

thanks!
 
If you have a center stand, use it...seems to keep things running much better. :-D Also, I like the photo shop rendering, but the air filters look a "little thin" to me!!!!! \\:D/

ha....pretty much.
 
Nice job hanging in there with this bike. Lots of folks would just have given up! If you're willing to learn (study these pages) and possess some perseverence, you'll be rewarded in lots of ways. It's good to see young people appreciating these old bikes and all the stuff that goes with them. Tinkering is a way of life.
