Hi all, I am new to this site and have just recently re-purchased my old 1990 1000 exup. the bike is in generally good condition but feels breathless. The carb tops are cracked and I am told are no longer available as new items, anybody got any suggestions ?
cheers, Adam

Are you meaning the plastic covers over the vacuum diaphragm chamber? Or are you meaning the rubber diaphragm itself? It'll have a big effect on the outcome of the request if we know what it is for sure your looking for. There is a recent carb diaphragm thread where we discovered a suzuki part number for replacement, the Stig found those and I have found they are indeed a direct match.

If you have broken caps/covers they may be repairable with an epoxy cement or plastic 2 component product we buy in Canada called JB weld. Sand around the crack with 120 grit till it's roughed up mix the 2 components together and spread over said crack and let cure. It can be drilled, ground with a rotary tool, painted, etc.

Hope this helps

The plastic tops are not now available new from Yamaha, second hand only. Diaphragms are still available.

Scour eBay for a set of carbs. The spares will come in handy.

You can find almost all for our carbs at kedo in germany

Kedo.de

Look under trx850 , it uses the bdst38 carbs as our exup's or look ir bdst38 directly from the search engine

They have Both the hard top and the diaphram.
