Smooooth

Postby WingAdmin » Sun May 16, 2010 12:10 pm



My 1100 engine had started getting a bit rough. Especially at low RPM's, under load, the vibration was bad. And there was a growing flat spot coming off of idle that was making me look like an amateur rider every time I started off from a stop, requiring lots of clutch slipping. It got to the point this past week where I didn't even want to ride it anymore until I had dealt with it.

So yesterday I decided to take care of it. Oil change, valve adjustment, new plugs, carb sync. Two hours later, I took it out on the road for a test...and it's smooth like butter. All better. I'm in love with it again.

Amazing what a bit of maintenance can do!

I know exactly what you mean. I left this morning for a Patriot Guard mission and my bike was running terrible. It was missing and backfiring. I knew the problem was probably related to the fact I washed it last night and got the engine pretty wet, but I assumed it would come out of it. After a few minutes I had to pull over and check it out. Apparently one of the drain holes in my spark plug wells is plugged and it was full of water. I mopped up the water with a tissue, put the boot back on and viola, ran like a champ. My next project I guess is to get some wire and roto-rooter the drain hole.

Valve adjustment, eh? Don't suppose you had your camera nearby - sounds like something I'd like to be able to do. All I need is some good pictures and maybe a few words to go along with them, you know, sorta like a how-to article... :roll:

Of course. Pictures are sitting on my computer now, just waiting for me to write them up. :)

Thanks GS, I can't wait to give it a try. I've just changed my oil so it'll be a couple of weeks before I'm ready to change my oil again and give the how-to a try. I'll let you know how it works, out - your excellent tutorials make it looks so easy.

Ok, I have to ask. What brand gloves do you use? I purchased a box at the auto parts store and they constantly break. Yours look a lot heavier than mine.

Simple blue nitrile gloves from Harbor Freight. They break occasionally, but they're so cheap I just toss them and pull another pair out of the box. I wait until they go on sale and then buy several boxes (they are normally $10 for 100 gloves, they go on sale for $7 occasionally).

Sounds just like what mine is doing. Pulled out of Wallace Lake the other day and it sounded like I was only running on 2 cylinders. Allways happens when you have an audience. :x I changed the oil and synced the carbs, do you think adjusting the valves would make that much difference?

It can't hurt, but typically syncing the carbs will make the biggest difference in low-end smoothness.

Wow, someone else from Strongsville! I thought I was the only one...

I could see the GPS screen on your youtube video and saw that you have to be real close. I live on Webster Road.

I'm over in Crystal Creek - kinda glad I'm not where you are, I'd spend even more money at Lowes/Home Depot. :)

Maybe that's the cause of my 1200's backfiring today.... it DID sit out in the rain a couple of nights. It was covered with a canvas tarp but still got wet. Do you think the plugs, drain holes, etc. got wet?

It could absolutely be the cause - as you saw in the thread I just answered, malfunctioning ignition/spark plugs can cause backfiring. Pull the plug boots off and make sure the drain holes are clear. Then dry the plugs, cables, and plug wells. You can use a hair dryer, but a leaf blower is faster. See if that makes a difference.
