I bought that exact gasket kit and convinced myself it included the accelerator pump o-ring...which turned out to be the o-ring that fits around the drain screw. So, I want to stress that the basic carb gasket kit from Siriusconinc DOES NOT include the single o-ring that fits on the float bowl. Some kits have a bowl gasket that is attached to the o-ring. Not Sirius.

If you want that single o-ring then you need to buy it separately as part of the accelerator pump kit, or find a I/D 7mm...section 1.5mm o-ring because that will fit. The original dimensions of that O-ring are approx. 6.5mm ID, 9.4mm OD and 1.4mm thick.

I wrote to Sirius trying to convince them that some owners don't have a failed accelerator pump diaphragm and just want to replace the o-ring rubber so, maybe, include that o-ring with the gasket kit. But I did not convince them. So I bought a kit of 419 O-rings that has 23 of those size o-rings and that should cover my o-ring demands for a while.

The components are well made, but I noticed some minor issues with sizing.

The new needle jet is longer than the stock. Food for thought.

You look much less stupid locking your handlebar lock every night no matter where you park it than looking at the empty space where your bike was last parked.

I've rebuilt a few carbs for folks with first generation Rebels. I bought the second generation bowl gasket, which has the O-ring attached, carefully cut it off and used it. Never heard any complaints about it leaking. Link to what I'm referring to here: https://www.ebay.com/itm/New-Carbure...:rk:8:razz:f:0

Keepin' all the left over parts. Gonna use 'em to build another bike!

Flite, are you saying that the intact 2nd gen bowl gasket is not a perfect fit for the 1st gen bowl? Because of how the o-ring is connected, that bridge won't fit on the 1st gen bowl so you cut it off and then use the two parts separately once the bridge is removed?

that's good info because those float bowl rubber parts are the main things to replace in a routine cleaning that doesn't involve all the jets so 1st gen owners will either replace jets unnecessarily or start stockpiling jets simply because they are buying the right float bowl gasket. Or they can buy that 2nd gen kit and replace only the important rubber parts.

Well that's the $hits', thanks for the heads up @oggytherebel

appears CSI sells the o-ring in bags of 100,

I'll have to mic mine to assure ID and look locally.. Caterpillar has an extensive assortment.

P.S. CSI sells a nice grouping of Main Jets
Kit includes

#150

Yes, there is no cutout for the second generation O-ring "bridge" on the first generation carb. But removing it allows it to work. If you look at the two gaskets side by side, the only difference is whether the O-ring is attached or not. Removing the bridge and carefully trimming the now separate O-ring allows it to fit the first generation carbs.
