72 GT550 Carb rebuild kits and petcock

Post by 02RedWS6TA »

After searching for a few hours I can't seem to find any rebuild kits for the older style carbs. I was going to just pull them apart and clean them but figured while I had them open I might as well rebuild them.

Anyone know where I can get rebuild kits for them?

Also, anyone know where I can get a new fuel petcock (the one with the 3 lines and the overflow) for it? I will get a rebuild kit for it but would just prefer a new petcock.

Thanks.

Try these (clicky linky and let us know how you get on.
I know that sale has ended, but if you contact the vendor with full details, they should be able to help.

These come up on ebay from time to time but are usually stupid prices. Remember the early GT380 and 750 are the same when you search. If yours is reasonable, it would be best to keep it and keep looking for a spare!
GT Reiner list them at 160 Euros HERE (clicky)
Crooks Suzuki in the UK are very good too.
Think of how stupid the average person is, then realise that half of them are more stupid than that.

I just rebuilt my petcock on my '72 GT550. I got my kit on eBay which included everything except the diaphragm which creates the vacuum on the back side of the petcock. Suzuki didn't make it available, but it's the same diaphragm as the Kawasaki H1. I was able to get the diaphragm from John Lutz at Mid-Atlantic Motorcycle (http://www.midatlanticcycle.com/store/). I called, spoke to John, and he was extremely helpful. Quick and cheap shipping too.

Also, be sure to get the little fiber washer that is on the vacuum side as well.

There's no sense in purchasing an NOS petcock for $250+, when you can rebuild it for around $100.

It really irks me when folks come on a forum, ask a question and get help, then sod off and never return, or perhaps return and don't acknowledge the help given. :x

Settle down...Check the timestamp on my reply above. I'm not in the business of blowing people off. I replied to this around the same time I posted my thread.

I haven't been on the forums since the time I posted until now. I'm very thankful for your help and not looking to get my questions answered and bolt. I'm looking forward to learning more on this forum. I've got plenty to learn.

Oh, I'm settled, but at least give us a chance by posting with the same name.
The original poster only posted ONCE under the 02RedWS6TA moniker.
