What will cause bluing on front exhaust pipe on 2003 yamaha v-star 1100

Ronald, All stock single wall pipes will blue some time or another. A big cause of Bluing is a badly tuned bike, burning rich or lean putting more heat into pipe.
There are polishes available to remove the Bluing, and some people on forums, they suggest to remove and with high heat paint, put several coats inside of chrome pipes.
Check the attached links,instruction and guides, Good luck

Do V-Twin exhausts help in reducing fuel consumption?

V-twin exhausts increase the power of your bike and so will use more fuel but it is the riding habits of the biker that affect the fuel saved on the motorcycle. The right motorcycle exhausts will use the right amount of fuel.

Hi, Thomas and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. 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.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage check for spark leakage in the dark.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets

I want to set my points on my yamaha xs250 twin do i set my left hand points then four cycles and set the right hand side

Your points will fire on the combustion and the exhaust stroke. Motorcycles use a wasted spark set up. The points will fire every time the piston approaches top dead center. Set the plate point set first(If there is a point set that you have to turn the mount plate to set). The plate set also times the motor. Then gap the second set.

Timing chain tensioner adjustment

all v twin engines are noisy, if you could totally silence the exhaust noise, you would be horrified how awful the motor sounds, it could probably do with the cam chain tensioner ADJUSTING. i wouldn't think it would need replacing. unfortunately the manual only recomends this being done by a qualified tech, i have a xvs 650 with same trouble. i would adjust myself if i could find out the correct tollerences.
