Here For A Good Time!
I need some help here guys,
A friend brought his 1200C Montauch over to me this weekend to see if I could help him figure out why he can't keep it running. He rode to Lowes a month ago, bike ran fine on the way there. When he came back out to go home the battery was dead and it wouldn't start. He tird to jump it off a car and it would not even turn over so he trailered it home. Put a new battery in a few weeks later and it fired right up but wouldn't idle and ran like crap.
First thing I did was adjust the valves, hadn't been done in 2 years. When I pulled the plugs(primarys) they were both black with carbon. Valves were pretty close, just dialed them in a little. I then cleaned and oiled the air filter(K&N). It was time but not real dirty. Then I pulled the O2 censor and wire brushed that and cleaned it up and reinstalled. I started it up and it ran pretty good but had a low and rough idle. I ran a few ounces of Sea Foam through each TB tube (these bikes have one common TB under the air box for both sides) let it sit for an hour and then took it out for a ride.
I got it to operating temp and took it for a good brisk ride running it hard up through the gears several times and it ran strong and idled smoothly after several miles. Put it back on the lift in the shop and the plugs were clean and dry. Started it up and it would sit and idle. My friend came to the house that night and rode it home, ran great for 4-5 miles and the quit twice on him in the next few miles. He could smell the unburned gas as he rode and when he got home he couldn't park it in the garage it stunk so bad.
Any clues or suggestions as to what we should be looking at next or what might be malfunctioning.
i appreciate any help we can get!
