20 kicks sound like you need a new top end. How many hours on the top end?
-
Chain?...What chain? I have a belt-drive on mine.
-
x2, choke tube not connected.
-
new pipe seals and still spraying black

My fault, I meant silicone. Use the high-temp rubber hoses and hose clamps at the mid pipes as suggested. That's exactly what I use. -
Is the choke tube connected between the two carbs? Sounds as if you have an airleak.

Use high-temp rtv glue. Put a nice layer on both flanges but don't get carried away, install the pipes, and let it cure for 24 hrs. -
I had it wrong, he told me the stock carbs on that port job only like a half turn out on the air screws. Try that and see what happens. Also, try switching the plug wires as suggested.

I had the same problem with coolant leaking onto the right pipe after the bike had warmed up. I too thought it was a leak. I found out the fluid was coming from the overflow tube that's zip tied to the frame behind the radiator. I stopped refilling my coolant tank after that and haven't had that problem anymore. No overheating either

Did you turn the air screws only one turn out? I had the same port on stock carbs from Kevin before.Both sides bog or just the left? Try giving the carbs a good cleaning. May have a clogged pilot on the left side.
-
Did you sync the carbs?
-
Problem fixed. Thanks guys for all the suggestions.
-
Compression is good.
-
May have developed an air leak. Just a thought
-
Can you take pics of the reed cage and post them?
-
Its a 421 cub. I'm in MS and at sea level. I have been running the 175 the whole time and never had a problem with a bog until now. A bog when I'm not in the powerband and a sputtered rev up top on that one side.
-
How did you come to this conclusion of not enough fuel?
-
My thoughts exactly. Did you perform a leakdown test?
-
Could be a number of things. What is your jetting?
-
It stayed with the same cylinder. When I'm not in powerband and throttle it, it bogs which causes me to have to downshift. I replaced the reed petals about three months ago.
-
Would the reeds cause a problem like this?
-
What carbs, needles and jets are you running?
-
No, you need to go down and do a plug chop. Why didn't you try the 270 mains?
-
Info. on the motor is needed.
-
Wow, never seen anything like that before!
-
I was running T5s and pod filters with a 280 main at sea level. I'm thinking you may be a little rich.
