    I'm fitting a '94 cv carb to my '75 shovel. I'm looking for info on what I do with the nozzle at the top of the carb in the rear. Also what air cleaner and backing plate to use since my bendix filter won't work. I could use a manual on this carb if anyone knows where I can get one. Thanks

    You will need an adapter to fit the cv to the bendix intake manifold

    Here is one for sale on Ebay

    There is a VOES vacuum tap on the rear of the carb. That can simply be capped to prevent leakage.

    There needs to be a brace from the air cleaner backing plate down to the center upper crankcase bolt on an angle. This can be as simple as a strap of iron, stainless steel. This will support the carb and prevent it from tipping and rotating the manifold out of position.

    You will need a set of throttle cables from around a 1993 bike. If your bike is pre-double cable, you'll need to get a throttle control that has the double cable. The 1982 already had this.

    Jetting is pretty simple - Start with a #48 midjet and a #165 main jet and it runs very nicely. The idle jet passage, if opened up, should have about two turns out on the idle jet but this may vary according to your engine. The slide, spring and diaphragm are best left stock with no modifications. If you have popping go to a #50

    Thanks for the tips. I have the adaptor and cables and just found a manual online. As soon as it warms up, I'll tinker with the jets again.

    from what I've read on these forums the cv is the way to go. As soon as it warms up I can't wait to get my hands dirty again. I put new .030 over wiseco pistons in her- the old harley ones where almost 2ozs different. That should take a lot of the shake outta her. Come on spring!

    Ya got a little bit of a wait ahead huh Joe? I noticed you are from North East PA. I used to live in that area. I was a ski bum working at Elk Mountain Ski resort back in the late 70s. Feels like a hundred years ago. Brings back a rush of great memories.

    It sure is a great place to ride. I hope the CV works out for ya.

    Good luck

    the cv carb didn't work out. It kept spitting the gas back out. RE-built the bendix with a new kit and used the original main jet (I put in one of them adjustable ones) and it now runs good. I had a problem with the screw holding the condenser on- it was a little too long and screwed up the advance weights.

    I guess I want to know what makes other carbs more desirable in comparison?
