2 Idle issues
Hey guys. So I have a 2002 earshaved vn750 with close to 24k miles. It has both the MF battery and the expensive spark plugs. I have two issues I have been fighting with ever since I did the ear shave this past May. the reason I did the ear shave was because I had to take my carbs off to replace a torn slide diaphragm. The problems I have had since are:
1st: When revving up the rpms never go back down to normal idle like they used to. It probably takes it about 4 seconds (the Mississippi kind) for it to get back to normal idle. Is this normal? I feel like it shouldn't be...
2nd: This problem has been getting progressively worse, but once the bike is warmed up enough for the fan to kick in the bike cannot idle at 1100 rpms like it is supposed to. It will try to and then it acts like it is misfiring or something until the rpms drop too low and it dies. I actually have it set at about 1700 rpms so it wont die on me.
Now I found on here that I should check my voltage at my battery and see what that says. The reading go from: 13ish cold. Idle: low 14ish reving it: 14.5 ish . When the fan kicks on it will crawl down from 14 until it is around 13 & when it dips below 13v the bike starts misfiring (I think) till it dies.
I have been trying to solve this issues for months now and had to ride it out to CA from TX like this....any wisdom passed my way will be appreciated
(also I have a video of the 1st issue, but can't post it here for some reason)
