1997 VN750 Running Badly!

Hi, I am new to this site and this bike. I bought it a month ago. When I bought it it ran great, until I rode it through most of the 1st tank of gas. Then it started bogging down, having little power. This continued off and on. One day it ran perfectly, the next badly. At 1st it seemed like maybe it was because of the amount of gas in the tank. The more I drove it, the more I questioned that. I changed the plugs and no difference. I used the expensive plugs. after a couple weeks, it started running badly at all times. It idles very slowly. Even if i turn the choke all the way up, that does nothing. I am wondering if it is a fuel problem or maybe a spark plug wire problem. The bike has 15,000 miles.

POGS is a strong potential if your symptoms develop after the bike has run for a while. Meanwhile a few tanks with SeaFoam and a serious vacume leak check would be on my list of things to do These CV carbs are very sensitive to vacume leaks. Their vacume systems are very basic so not a lot of lines to check but even a tiny air leak from a cracked line or a poorly fitting carb boot will really affect performance.

Sounds like its possibly a fuel problem. Might be a good idea to drain the fuel bowls on the carbs and see if any junk comes out. I would also do a search for Wolfie's back blow procedure and do that. See what those things do and let us know.

You may want to run some sea foam through it too.

re help

Thanx! I will try gas cap 1st. I have run seafoam through the system right after I got the bike, for a few tanks.
