Question about Yamaha Motorcycles
Hello folks, I have a 2004 Yamaha V star custom 650cc. When I drive it at about 70mph it starts to skip, pretty bad actually. I have had issues with the final drive in the past and just recently replaced it when a final drive that has good splines on the gears and just took it off about a week or two ago to make sure they were still nice and lubricated. Even re-applied grease to make sure. So I don't think the problem is the final drive this time, I just don't see how it could be. Especially because there aren't any issues whatsoever with the acceleration or drive until it hits the 70mph mark(which I drive that fast all of the time with no issues). This issue also just started today and was fine last night. It stormed really bad last night so I'm wondering could I have possible gotten some water in the gas tank? Would that cause my bike to skip at high speed or something? What other reasons would cause my bike to do this? Once again this just started today after a bad storm last night and I just can't see the final drive being the issue since it was recently replace plus lubricated/inspected about a week or two ago. Thanks for the help!
I am not clear about what it is doing when you say skipping

Testimonial: "Like puttering maybe...there is a minor jerk when driving like it's running out of gas sort of, just not as bad but it's still very concerning. When driving at a consistent yet high speed it will skip as if it can handle the speed almost(although it can as I always drive this fast ever since I've had it). I don't know if that clarifies the skipping definition good enough for you but I can't really think of any other way to put it. It's a minor skip in the acceleration that kind of jolts the bike back a tad bit during driving....almost as if it's running out of gas but only happens at high speeds and the tank is full! I filled it up the night before than the next day after the storm(earlier today) I drove it to work and once I get it up to 65-70 mph it skips in the acceleration or just at idle speed."

SOURCE: Trident 900 - No Acceleration
The only times my 'dent had no acceleration, it wasn't firing on all 3. Easy check: start the bike, let it idle for a couple minutes, spray water from a spray bottle on each header. Chances are, there'll be a cold header from a cylinder not firing due to a bad coil.

sounds more like a fuel problem to me. is it cold there did you use stabilizer in the gas? try some berrymans B12 in the gas it cleans everything up internally. it worked for me

SOURCE: Replacing broken drive shaft
the u joints definitely need lubrication and as far as breaking a drive shaft I personally have never seen one break unless someone has been really hammering it or doing a lot of burnouts

I had the same problem 2001 XVS1100 Custom
this is a starter issue Over time the starter on this bike twists when its under a load.
Look at the two bolts holding the starter on if they are not straight across then its twisted. turn starter back in line with a pair of big channel locks and try to start this should do the trick if this works i would recommend taking the two bolts out and bend them back straight or replace and reinstall starter this should fixya problem
Hope this helps ...............Jimmyfixya
