A bit more information. For the last few days, I was trying to find the 1/8 inch line that I can use between the accelerator pump and the front carb, but have been completely unsuccessful. I tried pretty much every store I could think of, though I did get a lot of "Did you try..." information from people I asked. Saturday morning, I put the carbs back on the bike because I could put the fuel line on with them on.
At the same time, my airplane is going into annual, and I headed down to the airport to clean the oil off from the belly yesterday, figuring I would have to mail-order the line from dennis kirk or something along those lines. When driving by a hanger I saw someone polishing his 97 Triumph, and stopped to chat. Turns out he is getting ready to sell it, only 4000 dollars, but that's still a bit out of my league.
I mentioned rebuilding the Vision, and that I was not having any luck at the fuel line. "You mean this stuff?" He gave me a foot of it free.
So, I came home after a couple of hours, and I installed the fuel line. I didn't have the right size clips to keep the line on, but it's a good pressure fit for the moment. I put the tank back on, but not the air box or filter. Connected things up and turned it on prime. Discovered I had a slight fuel leak at the brass bolt that covers the get near the bottom and tightened that up. Also had to tighten up the screw under the carb which covers the bottom get.
Rolled the throttle several times, and turned the engine over. It would catch and then die.
Nothing. Then I walked around the bike and there was something missing. I hadn't put the YICS on. I couldn't find the bolt that connects it up, but I attached it and used a different bolt to hold it on. Rolled the throttle several times, hit the start button and she started up (well, after a bit of coaxing.) Used the idle adjustment to bring the idle up to about 2500 RPM and let it warm up.
After it was warm, I started moving the throttle up, and right around 5000 RPM, it started bogging down to the point of almost dying. However, when I let go of the throttle it came back (unlike last time). I gave it more gas and it choked a little through 5000 but climbed on up to 8000 RPM and stayed there. It ran rough, but it ran.
Shut it down and let it cool off for a while. I removed the tank again, and came up with a list of things to do:
1) the main line for the fuel return is too short, it kinks when I connect it up to the petcock.
2) get clips for the new fuel line.
3) find the bolt for YICS and test it for leaks. (there was a slight hesitancy when I let go of the throttle)
4) put airbox back on and then adjust the sync, after I clean the air filter.
So, it's pretty close. I might need some mixture adjustment. I didn't remove the mixture adjustment when I cleaned the carbs since it was running well at lower RPM. I couldn't find a dip here in California, and apparently Santa Cruz is the boondocks when it comes to non-standard auto and motorcycle supplies! I'm going to try the 4 things above first and see what comes of it.
Based on the way the airbox is laid out, I need to tune the carbs with it on, and I assume I attach the sync gauge (I have a carb-stick I got from my dad) to the YICS ports?
Brian (no, this isn't an April Fools joke. It really ran...)
