Replacing rear shocks

Hi, I have a 1981 cb650 and the shock is original and very very soft, especially for my weight. I weigh 250 pounds and I am looking to improve comfort and cornering by installing new shocks. I received an amazon gift card for 100$ for christmas and I'm going to try to put it towards rear shocks. her...

Re: Turning petcock to "on" kills the engine

Thanks for the reply. I don't idle it for more than a few minutes at a time, about the time it would take to warm it up. A quick google search says that tapping the back end of a screwdriver on the bowls might free up the floats, I will try this. I'm trying to avoid having to pull the carbs again bu...

Turning petcock to "on" kills the engine

Hello! I have a 1981 cb650 that I just got up and running after a bit of carb work. I changed the plugs, it has new gas, new air filter is on its way, and new stock size 120 jets. I've been running it every morning to get the seafoam that I put into the gas to run through the carbs. I also removed t...

Re: Bypassing CV carbs vacuum controlled petcock

Welp, this sums up what's going on right now: http://www.youtube.com/watch?v=AXwGVXD7qEQ I got her to idle! She sounds great. One issue though, my header for cyl #4 is not getting hot. I pulled the drain screw and there was some gas coming out of the bowl, but it didn't come out as quickly as carb b...

Re: Bypassing CV carbs vacuum controlled petcock

I think I might have had the floats in the wrong way. I'm not sure but I just took the carbs out to get out the old o-rings and put new ones in, and I figure I should check. Does this look right to you? http://imgur.com/a/7LZKU In that picture the "flat side" of the floats are facing forwa...

VB44A Carbs for sale

Hello I am selling an extra set of carbs that I bought with my bike. I am not sure what they are worth so I am taking offers. They are about 98% complete, the pilot screw o-rings and washers are missing, along with a couple of the screws that hold the float bowls secure. I have the vacuum shutoff bu...

Re: Bypassing CV carbs vacuum controlled petcock

So I found a video that shows a cb650 start up after a long hiatus. http://www.youtube.com/watch?v=nY60C_nv4pk I've tried starting it before, but I definitely didn't do it as long as he attempted it there for two reasons, 1. a fear that I would burn up my starter and 2. the fact that my battery is c...

Re: Bypassing CV carbs vacuum controlled petcock

Okay I've got it cut to a good length. I thought the reinforcement on the fuel line was metal but it turned out to be fabric so it was easy to cut. I'm waiting on a battery to try starting her, at which point I think i will have more questions. In the mean time, I was wondering if anyone might know ...

Re: Bypassing CV carbs vacuum controlled petcock

If you took out the vacuum shut off youll need to replace the fuel anyway.It should be to short if I remember right. study a diagram closely. there are 4 lines going to the shutoff. Be sure you hook up the right ones. sharp scissors work well on fuel line. I ended up using the fuel line from the ta...

Re: Bypassing CV carbs vacuum controlled petcock

So I took of the vacuum petcock and routed my fuel line directly into the center port. Only issue now is that my hose is too long. I have to turn my petcock, which leaks in this orientation, but not when facing the right direction. Is this normal? Here is what it looks like: http://imgur.com/R4qUcKv...

Re: Bypassing CV carbs vacuum controlled petcock

no There shouldnt be 2 on the bike. Dont know the story on the pic. Make sure you petcock works good and get in a habit of shutting it off at nite. Only one is connected to the carb, I just put them next to each other for comparison. I actually have no idea where the part that is connected is from,...

Re: Bypassing CV carbs vacuum controlled petcock

Awesome, I'll do this tonight. So I won't need either of the parts in the picture? I just connect the tank line to the port between carb 2&3?

Bypassing CV carbs vacuum controlled petcock

Hey guys, what's up? :D I bought a 1981 cb650 earlier this summer and I've been working hard on getting her in shape. I just finished with the carbs, and tried starting but no fuel got to the carbs. It escapes the tank fine and the hose is good, I think the problem is at the automatic fuel shutoff o...
