Question about 2006 Yamaha V Star Classic
On my Yamaha xvs650, it only runs on one cylinder for a while and then the other one kicks in. I changed the ignition coil to that cylinder for a new one same problem I am getting a reading of 1.7 OHMS on the new coil. WHAT CAN BE THE PROBLEM !!!!!
Hi, Butts2 and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose.
6. Faulty ignition coil or ignition / electronic module
7. Faulty CKP, CMP, or BAS sensor.
8. Faulty ignition switch.
9. Tilt sensor needs a reset.
10. Security alarm failing to disarm needs reset

I ride one of these myself good old plodders,one of your ht caps is leaking so replace both spark plugs and caps that should cure it,keep it upright.

First you'll need to get a jet kit from West coast star. Then you'll need to jet the carbs to run equally. This may take some trial and error. Another thing that worked on my bike was the upgraded coil kit they sell. It's almost double the voltage of the stock coils and comes with better insulated wires for a more uniform resistance. I haven't had this problem since. It'll make the cylinders fire evenly and save you from those pestiferous fouled plugs. I hope this helps.

hi,says here you had the carbs redone,it sounds to me like the carbs were not rebalanced after installation,if you do any work at all ocn carbs it is quite important that the carbs be properly rebalanced,it only takes very minor adjustments inside carbs(even a scratch on a jet)or different torque settings on screws etc will trow the balance out,if you get this done i think your problem will disappear..hope this helps
