Carb rebuild problems

Post by Chiller449 »



Hey guys, so I decided to rebuild the carbs on my bike. Bought a decent kit off of eBay and got them all tore apart. I took note of how many turns out my idle air screws were. 4.5 turns out so I set them all to 4.5 turns out. Rebuild went smooth. Carbs weren’t too dirty ( the bike ran really good so I figured it wasn’t too bad) so I installed them back on the bike and after syncing them the bike barely runs. It will start and idle pretty good. If you try and give it throttle it falls on it’s face instantly. If you give it throttle very slowly it will rev to about 5500 rpm then die out. It also smokes like a freight train out of the right tail pipe. Left side is fine. Any ideas? The rebuild kit looked good. I did notice that the jets it came with said 145 on them and the jets I took out of the carbs said 14. Not sure if that’s causing an issue or not. Thanks for any help.

Let's review the facts.
The bike ran good before the cleaning and now doesn't.
The only difference you note is the numbers on the jet.
Did you happen to compare the hole in the jet?
Why replace the Jets..they don't wear out..just get plugged up.
We're the Jets EXACTLY like the original ones.
Was it the slow jet or main jet.?
Did the sync turn out ok?
Is one set of floats installed upside down?(Yes that did happen to me once)
Either way this turns out,you'll have to pull them again.

I replaced all the jets because I had new ones. I’ll have to tear the carbs back apart and take a look at them. I saved all my old stuff I’ll probably just re use them. What should I re use and what should I replace?

You can use all the new stuff if it's identical to the old stuff.
The only issue is if there different then use the original.Cleaned of course.
Never "drill out" a jet to clean it.That hole is very precise in size and the slow jets are very small.Even a sewing needle is too big.
If you changed the needle valve/seat you must check/adjust the float level as needed.
