klx race head question

Welp, I just replaced every single gasket, spacer, and o-ring in the intake and they ALL leak. I'm left with two options:

1. RTV the out of every surface

2. get a race head kit that replaces the complete intake track (minus carb)



My question is this, all the manufacturers seem to list their race heads with their big bore kits. This leads my to believe that their big bore pistons are cut for valve clearance with their race heads. Am I going to have issues running a race head on a stock displacement/stock piston bike?

Important Note: This kit does not contain a piston. You will need to either use one of our newly modified pistons or check your your clearances very carefully and modify your piston's reliefs to clear the bigger valve

How is everything leaking? Did you replace all that stuff becuase it was leaking to begin with and it's still leaking?

Yup. It didn't matter at which connection you sprayed carb cleaner, the idle would increase. So I purchased two new spacers, 3 new o-rings, and a new gasket......basically everything that itsn't metal behind the carb......and it STILL leaks!

I'm guessing something is warped.

Double check that the leak isn't from the throttle cable as it passes through the rubber on top of the carb. I had troubleshooting a high idle cause everytime I sprayed a connection a little was being sucked in through that rubber.

running a head with larger valves usually require that reliefs are cut into the piston

throttle hangs sometimes when you rev it.

Motor runs hotter than I like (which says lean to me).

Idles up randomly and occasionally stalls.

I'll check. I was trying to localize the carb cleaner as much as possible to a particular connection, but I wasn't using one of those tiny straws.

Changing the head wont change the intake unless you specifically change that intake or a kit comes with a new intake. Every seal cant be leaking. Im sure its just getting sucked thru one leak someplace. You can get a new intake if you want without getting a new head. Rob is right, most aftermarket heads have bigger valves and will require bigger reliefs to be cut into the piston to not make contact between valves and piston. There is a seal under the throttle slide cap that is rubber and can leak. You cant overtighten that cap to distort it. Rob has the same problem with his cap gasket. That could also be your problem as Jason suggested. Just some things that might help.

Be sure and check the mixture screw setting as well.

Also double check those O rings, they dont like staying in place. I usually have to use some grease for new O rings to help keep them in place till they get bolted tight.

I think I may just douche all the connections with RTV tonight, and be done with it.


EDIT: after looking at the throttle cable gasket.

Good call on this. That does seem to be the problem. The sacked out rubber was being held on by a ziptie.

The previous owner must have had an aversion to ever purchasing maintenance items for that bike.

PoPo: If you remove the choke butterfly and mechanism on that carb, put a pod filter, and use a 85 main and 40 pilot and adjust the air/fuel mixture that carb does pretty well.
I have a carb setup that way if you want to give it a try and see if you like it.
