Thanks

Need assistance or a schematic for the vacuumlines to the carbs for a 2002 Yamaha Royal Star Venture. Thanks...

New fuel pump arrive on Friday, connected and no change in status. Bike would not start??? I removed the carbs, float bowls and found some discoloration (dark red) and cleaned the bowl area. Removed the parts that I could and cleaned them. After putting the carbs back together I tested the floats with air. Carbs up in right position, I could blow air through the carbs. Flip the carbs upside, couldn't blow air through. Connected my famous funnel, poured fuel into carbs and fuel came out drain screw (when opened) and funnel level was decreasing. Floats appear to be working??? Reconnected carbs, fuel pump and connected my funnel to bypass gas tank and fuel filter. Bike sputtered but after several attempts, bike now runs with choke on at an idle but I cannot throttle or disengage choke without stalling. Based on my limited knowledge I'd say that the carbs need additional cleaning? Looking for more expert advice? I was surprised at how simple it was to remove the carbs, so I could remove them again. Not very comfortable with breaking down the carbs. I did read about a throttle sensor on carbs? Could that be a problem? Also, the carbs appear to have heaters? Could they not be working, causing problems with starting in the cold? Thank for the all the help! Milt

Thanks for the replies... Cranking appears good and since I am having issues with starting, I have been using a jump box due to the extra cranking to keep the battery up. As for valves and other services, I have no clue. Bike has 18,000 and ran fine when I looked at it. Like I mentioned, if I spray fluid directly into the carbs, it will start, run until the fluid is empty. Hard to keep 4 carbs full and running by spraying the carbs but I was able to accomplish that for a short bit and bike continued to run??? I did replace the plugs with NKG and since the plug replacement the bike was started with spray for the short bit until the carbs emptied, so I would believe spark is not the issue. I definitely believe it is carb/fuel related??? The bike ran and started fine when I was looking at it and purchased it? I test drove it and ran fine? Just between getting it home on my trailer (3+ hours) and unloading it, I couldn't start the bike. I haven't drained the carbs and that is my next plan of attack. Ordered new fuel pump, fuel filter and a manual. I currently have the fuel pump and filter bypassed. Would bike run with a short line and small funnel connected directly to carb, bypassing fuel pump? I attempted this set up and the fuel was not sucked into the carbs from the funnel? Not sure if carbs have any secondary fuel pumps? Reading on the forms, people mentioned running bikes on gravity feed in emergency? Is my set up enough for the bike to start and run? Fuel pump and filer are due to arrive on Friday, so I will connect my new parts and give it another go...

New to this site and Yamaha Venture. Recent purchased a 2002 RSV. Ran fine when I purchased but previous owner said it was hard to start in cold. Get it home and I cannot start this bike. Removed tank, bypassed filter and even ran line with small funnel directly to carbs, still not starting. If I spray carb cleaner in the carbs, it will start and run until cleaner runs out? Pump was not pumping but when I disconnected line and turned on, pump sprayed gas that remained inside of pump. Reconnected pump, made noise and stopped working??? Ordered new pump but shouldn't bike start when I had a funnel with fuel connected? None of gas was sucked from funnel while cranking? Thoughts and/or comments?
