Hello,
I just recently joined the forum and have been exuberant to find a community that caters to these awesome bikes.. I've had a lot of fun on mine before even starting the resto.. That, said, I recently acquired my first GS, a 650EX, and during the initial carb clean I noticed that one of the float towers on the #1 body had been previously broken and was not still sitting in the bowl.. meaning someone broke it and just threw it away. So after ordering a new #1 from ebay and receiving the stripped down body, I performed a 1 hour Barryman's dip on the new (used) body, and then a 30 minute water boil. After the boil I spent about 30 -40 minutes blowing out entire thing with an air compressor, checking for positive air flow through every jet orifice (and frankly any other hole I could find). I'm absolutely certain this new carb is as squeaky clean as the day Mikuni shipped it to Suzuki. The problem is, between the dip and the boil I'm left with a dull dark gray carb body, that is beginning to oxidize..
I feel like I did an extensive amount of research on this procedure, and I could not find one instance of anyone saying that this was bad, in fact I found people that said, despite the dull appearance the carb will perform as new.
I know that these carbs come from the factory highly polished and with some sort of sealant that deters oxidation for years. I'm just wondering, has anyone done this before? and what kind of results did you get? have I ruined this body, should I scrap it and start looking for another one??
I haven't done anything to original rack other than clean with Barryman's spray, but based on the bike's response, I still feel like all the carbs could use a deep solvent cleanse of some sort..
Scratching my head, hoping for an expert on these carbs..
p.s. I highly doubt I could go to Mikuni or Suzuki and expect to be able to order brand new carbs anymore, but does anyone know of a company making reproductions of these original carbs???
Many Thanks In Advance..
