I have a 2006 Yamaha Roadstar midnightstar 1700.. it runs fine after it warms up most time. But the problem is it acts like it is missing or flooding out while riding after you take off with in the first few miles. my shop has changed the pipes and installed a jet kit. but it still does it.. and they won't touch it anymore. anyone have any ideas?

Sounds like it may be over jetted, and running alittle rich. Can you see black smoke if you rev it up? Could be misadjusted floats after the kit was installed.

    I looked online, and your bike is fuel injected. Sounds like a problem with the program they are running in the computer. What type of add on did you get?

    i could be wrong, but i believe they started injecting these in 08, my 07 is carbed also. take the time to check the accelerator pump settings, mine was over set and constantly drizzling fuel as i rode. my carb changes didn't seem to give the results i expected until i reset the float level down a tad.

What oil do i run in my yamaha roadstar silverado

Any oil that is JASO MA certified motorcycle oil. 10w-40 for cold climate. 20w-50 for warm climate/touring. Car oils use different additives. Do not use any oil that says Energy Conserving on the label . It will shorten the life of your wet clutch and transmission gears. If you use Synthetic oils, they will help your bike run cooler and shift easier.

Fuel overflows (leaks) upon turning Roadstar 1700

not a throttle valve, but the float needle valve that shuts the fuel off with the float. the only cure for the sticking floay valve is to remove the carb and clean it.

I have a 2006 Yamaha Roadstar that is showing oil level is empty but when started it is showing full. Why is it showing empty when cold?

The Yamaha Roadstar has a dry sump oil system. What this means is that the oil is stored in an oil tank to reduce the size of the engine. By storing the oil in the tank (which is under the seat and has the filler cap/dipstick, the engine does not need a sump under the crankshaft to store the oil. In this type of system the oil is pumped back to the tank after making its rounds through the engine. When you shut the bike off the oil will settle in the engine until you run the engine. The procedure to check the oil is to warm up the engine and allow it to idle for approximately 3 minutes. Do not rev up the motor during this time as it will cause the oil level to not read correctly. After shutting off the motor, check the oil level and adjust it to keep it in the proper level on the dipstick.

How to adjust 2007 yamaha roadstar 1700 carberator

The most common adjustment would be to adjust your idle mixture screw. These guys make the job very easy with a thumbscrew to do the job. Tell them I sent you and that you need carb help.

They are great guys and very helpful. They have my bike running the best it ever has.
