SV stalling - June 21, 2012, 09:21 PM

I have an '02 SV650S. I'm the only owner, it has ~30k miles on it and a slip on is the only engine mod.

For a while now, I've been losing power, when riding. The tach will drop to zero and I think I'm losing a cylinder. I can maintain speed, but it's very hard to accelerate. If I pull in the clutch and rev the engine, it "fixes" the problem. When I'm having this problem, when I come to a stop, the bike will stall out. I can usually restart it easily. I have had one time, when I went somewhere, it was stalling a lot on my ride, after a stop, I had to have the choke on longer than normal in order to start it.

SV's (at least the 1st generation) are known to get water in the front cylinder. If that was the case, I was hoping it would dry out on it's own.

I finally had a chance to change my spark plugs, 2 weekends ago. I started it up after and it sounded great. My first ride, last weekend I ran some errands on it. It started up fine, was running great, until my ~3rd stop sign, when it stalled. It started right back up and was running fine again. On my way home, after a couple of stops, I lost "power" again.

Any idea what would be causing this?

When they are in 325 mode it's easy to tell. Pull the front plug and turn over to verify spark. If that's not it, it's not the water related issue and we can go from there

The problem comes & goes. Most of the time it's fine. If it was the water problem, would it be constant?

When I pulled the rear plug, it was loose. I was hoping that was the problem, but I'm pretty sure I got the new one in tight.

Put some dielectric grease in with the boots to keep water out. Check the coil leads for solid connection (coil side and boot side)

Do '02s have the drain hole on the right side of the front cylinder? It would always get clogged on my '05.

Where can I get dielectric grease?

I just called Advanced Auto and the guy hadn't heard of it.

Google shopping shows it at Advanced. I'll just go there.

Gunked up carb? Had you ridden it in the rain? Ran into the 325 problem myself but once I cleared it it's been fine ever since. Check your up right sensor in front of the battery box. The boot on it was torn on mine and it popped off the same time I was having the 325 issue.

Sprayed the boot with grease yesterday. It said wait 6 hours. Today I took the bike out. It did not want to start at first and was dieing, when I took the choke off. I took it out to see what it would do. Once it was warmed up, it ran like a champ. I did some highway, some city, stopped a couple of times and it did not stall. I'm hoping that fixed my problem. Thanks for the help.
