Intake Carb, Reeds, Manifold???

Let's talk abut the intake setup?

I have a few choices, one a 390/430 mossbarger reed assembly. Second I / we have the HVA V-Force reed assembly. Third I have the orginal Husqvarna reed assembly with boyzeen reeds. Mossbarger offers new reeds for the mossbarger manifold. I been thinking about which reed assembly to use on what bike.

1. '82 430CR
2. 80 390cr
3. 79 250cr

Are the V Force reeds that good? Better than the mossbarger? A little reed education.

I plan on using the thunder products UFO in all my carb sleeves.

Depends if you have built them as bottom end or top end motors, softer petals or dual stage might be better for a lugger and a stiffer set up for a screamer.no idea about mossbarger and probably have to compare the two side by side on a stock engine.

The only experience I've had is with the boysen reeds. You will have to re jet with the 2 piece reeds.

I / we have to jet leaner with the boyesen reeds and the UFO in the bottom of the slide. I think I'm going to try different reed setups in different engines.

82 430cr v force, w/UFO
80 390cr mossbarger if they offer new replacement peddles. With the UFO
79 250cr boyesen reeds w / UFO.

Mossbarger makes the reed assembly for the 82 & up rectangle reed box for the 250, 430, 500. I'm not sure what year the 430 changed to the rectangle reed box.

It, the 430, changed when the cylinder casting was a water cooled one.

I wish I had a dynamometer to see the difference between the flow of the different brands of reed setups. For you guys who run the v force reeds is there a big difference?

Mossbarger sells replacements for anything they made. they had 5 petal reeds for my 80's Mossbarger.

At the mossbarger site they give a flow chart when comparing the different reeds.
