does anyone know the thread specs for the carb bowl screws? thanks

 

like what size they are?

 

I dont know exactly what size they are but i went to sears hardware and picked some up out of there metric bolts. I think they are a must! Just go to the hardware store with one of the stock screws then take a nut out of the box that fits that screw and find the mate for a bolt thats what i did. I do know that the head is 7mm. I had to machine down a socket to fit it right but its WELL worth it(the socket hits the bowls and binds up so i took a diegrinder since thats all i have and just went around the tip of the socket to make it smaller now it fits no problem and I wont strip those cheap screws anymore. I stripped one of those stockers and get lucky when i drilled the head out that it was easy to get the rest out.

 

Yes, I am trying to find what size they are, I think they are a M4 and wanted confirmation. Thanks

 

What carb is this for? Just curious cause you posted in the yamaha forum but you sig says you have an ltz400 [img]i/expressions/face-icon-small-smile.gif[/img] Reguardless if it for your ltz then its an M40,7mmx10mm

 

M4 sounds about right i don't remember for sure though. I got the ones that take an allen wrench from LOWES. No clearence issues and much better that using a screw driver.

 

To clarify I am interested in the Raptor screw spec.

 

OK thats a mikuni 33mm BSR....... Im almost posative it is the same ..... just called my friend and he doesnt forsure remember but I dont see why it wouldnt be, because the predator's mikuni carb and the ltz mikuni carb all have the same bowl screws. Just take 1 out and run to Lowes home improvement center.... go in the hardware isle ... which has the boxes of machine screws and compare it to yours. They have the allen head screws there. M40, 7mmx10mm

 

I put allen heads in mine as well from Lowes. Tip on getting stripped screws out = take a small pair of needle nose vise grips and twist away....VIOLA...[img]i/expressions/face-icon-small-smile.gif[/img].

 

My tip for getting the stripped stock phillips head screws out is to take a Dremel tool with a cutting wheel and cut straight across the top to make a slot for a flat blade screwdriver. Worked like a charm. Then I replaced it with stainless steel allen head screws.
