Question about Yamaha Motorcycles

2 Answers

I have a 1994 Yamaha Virago 1100 that I paid a guy to rebuild and jet the carbs. After warm up it idles at about 1250 rpm's. It sputters and pops. Will a carb adjustment help and how should I do this?

06 v-star 1100 when twisting throttle and then back to idle position it takes a while to idle back down or stays at high rpm


More than likely the carbs are plugged up(makes the no idle, popping from the intake or pipe and sometimes hard starting), and/or a vacuum line(s) Is loose/broken, and the carbs are probably out of sync (makes the high sticking idle/little to no idle). I have many article written about cleaning the carbs and fuel system. Get the carbs and fuel system cleaned out if you are not familiar with the process.

I just got a 1997 yamaha virago 1100. It will not idle unless I leave the choke on and the engine revs at 3000 rpm. Runs perfect after 3000 rpm. Any ideas? Original factory carb settings? Thanks


Hi, Ungerconstru and the usual suspects are:
1. Fuel cap or fuel tank is not venting properly.
2. Fuel filter clogged.
3. Fuel line pinched or kinked.
4. Vacuum line from the petcock to intake manifold cracked.
5. Float needle and seat sticking.
6. Float level too low.
7. Carburetor bowl vent line clogged/blocked/pinched.
8. Idle adjusting screw set too low.
9. Air/fuel mixture screw set too lean.
10. Idle port, transfer ports, slow air jet clogged.
11. Slow fuel jet clogged.
12. Faulty fuel pump.

Engine rebuild and running fine. After a jet kit and carb rebuild engine will not idle. Carbs have been taken apart and gone through several times by several different shops engine has great acceleration...


Seems that the crank/timing settings needs a closerr look than to feel that the carb is faulty.The engine is becoming rougher because the firing angle is changed. I also doubt that the carb /jet kit be replaced back with the original as the new jet is not matching.
Now start the engine and set up idle to more than minimum so that the vehicle does not stall but is somewhat smooth. Now try to advance/****** the timing and notice if the engine becomes smoother irrespective of the TDC settings. If so set to the best level and bring down the Idle , do not reduce off air but check the mixture at the exhaust to have this done all over.
Somewhere in the new change a point has been missed..
