Is there an overflow vent on the carb that I'm not seeing or is it just normal to fill the airbox with gas when it does overflow?

Airbox -- turkey baster/paper towels

there IS an overflow vent (and should be a small hose attached to it) and a really spooged up float bowl could clog the vent, too.

I'm really at loss on this...... no idea what would cause it.



Everything checks out ok with the carb. No debris, no obstructions, float valve works as it should, needle depresses easily, etc.

Did that dual piston caliper bolt right up to the EBC bracket that comes with the 320 rotor?

The EBC kit was made for the Yamaha front end I'm using.



So any ideas on the flooding issue guys? I don't know what else to look for other than the float valve which looks perfect. Guess I'll just button it all up and try again.

Yes, the vent hose is the overflow and it should run down towards the bottom of the bike.This is the hose the T mod goes in.
Make sure your vent is clear, seems crazy that much fuel in airbox !!

Sometimes the needle and seat looks good but doesn't seal, replace them.
Check float, make sure it floats.
Check float level.

Thanks GG

The vent hose is clear of obstructions, T mod done. The float floats,... float level is unchanged and in spec, everything worked perfectly when I took it off the road last fall.

That's what is so perplexing about this whole deal.... I just wish I could find something wrong..... find the cause

I'll try my other carb if it happens again.... just wish I knew why it happened!

Stock petcock but converted to manual ... no diaphragm.


Hows your bike coming?

I'm bettting that it WAS clogged up somewhere (bowl. vent, somewhere), and that disassembly and reassembly, checking, poking prodding has cleared whatever the difficulty was . . . . .

Like you, I am not fond of "problems" that I fixed without knowing how . . .

In this picture there appears to be a line on the rubber seating portion of the needle. If so, that's your likely problem. It doesn't take much. Also, I've had them stick and a sharp whack with a small hammer (carefully) will fee up the stuck valve.

Thanks for all the input guys.

Everything is back together, I sucked 4 oz's of gas out of the airbox. Filter is cleaned and re-oiled, fresh spark plug. Some fresh oil tonight and I'll take it for a ride probably Wednesday when it warms up.

Fingers crossed!

Well I got out for a short blast today. Everything seems to be working fine!

I stayed close to home, I still don't trust it 100% . Took a few pics before I put the cases back on......





































Wow..... what an improvement! Suspension is just so plush and controlled.

The engine really surprises me though, this old 89 motor pulls waaay stronger than the 96 did. Probably a combination of less weight, KLX needle, clean filter, the lighter flywheel, LV pipe, and me not having ridden in months

I did notice the limited steering lock while doing a u-turn in the street though. I'll grind the stops down a little more, but not anytime soon. It's a minor issue that can wait till next winter. Over all ....... I'm pretty damn pleased with the result
