Extra part in carb kit?

I am helping a friend sort out a really clean '82 Maxim 650. I have checked out the site quite a bit so far and found most of what i needed through the search functions. I didn't see this anywhere though.

So maybe this is just an extra piece, but just wanted to confirm.... I ordered a carb kit from parts'n'more and there is a little aluminum plug in the kit. Does this go anywhere? I didn't see one in the carb when i disassembled and cleaned it.

Thanks in advance.

 

The aluminum disc is the substitute idle mixture screw port "plug" or block-off plate. I suggest that you don't use it, as once you put it in, it's really difficult to get out (just like the original plug that it replaces, and as it is designed to be).

 

hey - thanks! i was wondering about that too. I just put the old rubber plugs back in, as I didn't chew them up that bad when I took them out. Figured it would keep the idle screws clean anyway.

Here's another question about this rebuilt kit -

I used my existing brass bolts (don't know the proper word, but they were 10mm), instead of the new ones - they looked clean. The new ones didn't allow the fine metal mesh to be clipped on the bottom.

Am I going to run into any problems using the old brass bolts with the new float pins? Were the floats in the kit designed specifically for the new bolts?

 

What do you mean by "brass bolts"? Do you mean the float needle SEAT?---the thing that the float needle fits into? It's a lot bigger than 10mm I think.

Did an '84 XJ650 use Hitachi or other carbs?

 

10 mm is right for mikunis, not sure on hitachis.

SHould be replaced as a set. Doesn't matter how clean they are but it matters how worn they are. If the old needles have wear rings on them then the seats will be worn too. You might get away with it but if you have any problems then match them back up.

 

Yes, it was the float needle seats. Thanks, I'll not risk the chance that I'll have to take the carbs off, and just put the replacements on right now. I imagine the inline fuel filter I'm about to install will out perform those mini filters at the bottom of the OEM seats anyway,

Thanks again!
