Seafoam causing carb problem??

Have you went looking for it yet ..... replacing a Kerker unless its pretty banged up is crazy .... I like chrome and have always been a Vance and Hines and RC Eng fan so that's why I bought it.

Anyway its up to you .....Super trap is a good header......if you want stainless that's cool too... .....its just that most on here would die for a Kerker and you'd be hard pressed to find anything better..... but I suppose after coming off it could be tore up pretty good.

This bike has been a challenge and most if it has been self-inflicted. I have had my eyes out for the original 4-2 black chrome but that has been nearly impossible. I will keep looking. Here is what I ordered:



The headers are black so it will look fine. It ran fine with the other Kerker slip on that was basically an open pipe. It was loud and kind of beat up so I figured it would be replaced at some point. I am heading out shortly to retrace my steps and see if I can find the Kerker.

As mentioned before, a virtually open exhaust can likely be a source of your problems. If you had access to a more stockish exhaust (just to temporarily mount for some test rides), that would be a really big indicator as to how your particular engine responds, and may very-well answer some of your questions. I have a spare stock 4-2 KZ1000 exhaust hanging in my shop that I would lend you for that purpose if we were close enough. .........................................Mike

Gee, look what I found. By side of road about a mile from my house. I guess I did notice it when it fell off - this is when it got a lot louder. I guess I wasn't expecting this to happen so didn't stop until right after this spot. Anyway, back on the bike.

So, I took for a test ride and still have the "6 mile marker stumble" still going. Starts up fine with full choke. Warms up quickly. Runs like a bat out of hell for literally 6 miles and then begins to stumble. Particularly noticeable below 4K rpm. Throttle works but is slow to respond and when it does you can feel it bogging down. Above 4K I will get 1 second spurts of full power off and on. By the time I got home and shifted to neutral and stopped it died.

Third time since I reset fuel level height it has done this. I did a quick check while carbs on bike and it showed the level about 4-5mm below the service level. I guess I may have gone too far when resetting, but how could this be causing the 6-mile stumble?

You say it runs fine for 6-10 miles, next time it starts to stumble on your ride, try cracking open your gas cap, better done without full tank of gas, & see if the stumble stops, could be a clogged gas cap breather

True with most any engine that has a fuel tank. Fuel tanks have to breathe too or it creates a vaccuum and fuel can't flow to carbs like it needs to. I had a Craftsman riding mower that ran awesome for 4-5 laps around the yard then acted like it was running out of gas. Took me forever to figure it out, even replaced the fuel pump, but ended up cracking open the gas cap and has ran fine ever since. That's all it was. Motorcycle gas tanks work the same way. They have to breathe as well even when gravity fed. Dunk a straw into a glass of liquid, put finger on top of straw and it can be raised with liquid in straw...move finger and out comes liquid...exact same principal. Good luck. ........................Mike

My Jardine baffle blew right out on the freeway once too and it instantly got run over by a few cars. It took me a week or more to come up with a suitable replacement.

I will try the open gas tank lid - unfortunately raining right now or I would take it out. Tomorrow will be first attempt. I will also check the gas cap to make sure it can breathe.

well if the bike is in the garage you can open the cap, cover the fuel tank filler hole, & remove the 3 screws on the bottom of the cap & take it apart to see if the gasket & breather are in good shape, I hope you're using JIS screw drivers, because you have a good chance of stripping the screws, They look like Phillip screws, but are JIS screws, just like the rest of the screws on your bike

Pete - I took it off and apart. Not quite sure where breather is - what am i missing?

Ran it again tonight. Same story - 6 miles and then started to sputter. Pulled over and opened gas tank cap and then closed and started. Same story. I went a little further and then pulled over again and opened gas cap to where it was slightly open but wouldn't open all the way. Same story. By the time I got home it was barely running and died when I pulled into the driveway.

Pulled the plugs 2-4 looked normal - tan in color. Plug #1 looked totally clean - like it had not been used. Mean anything?
