Reed spacers for this RD350 Setup?

[andrewlk]

General Setup:
1973 RD350
Pistons are one size over stock
K&N y-boot air filter
DG pipes
Stock carbs and manifolds

Current Jetting/Carb info:
210 Main Jets
5I4 Needles 4th clip position from top (top being the not pointy end)
2.5 Needle Valves
2.5 Throttle Valves/Slides
175 0-8 Main Nozzles
Air Screw 1 1/4 turns out from seated
Throttle/Idle Screw 6 7/8 out from seated

Questions:
1. Should I even consider reed spacers? With everything apart I plan on adding a crossover tube and manifolds, so if I was going to add them it'd make sense to do now.
2. If adding only the crossover tube, would I need to rejet or can I just fine tune?
3. If adding both spacers and the crossover tube/manifolds I assume I would need to rejet, yes?

Also will be installing mzb ignition.
Thanks,
Andy

I run a set of 10 with a boost bottle banshee cages and tdr single peddle reeds and 75os wisco banshee pistons 30mm pwks and k&n's and a huge port job so my advice may not help but i would try them there cheap and if thats your quad in your avatar then there not a waste if you dont like them

I thought maybe down the road I'd get banshee cages and might need the spacers to make the port job work anyway, but good call. Though lately I've been considering selling the quad to get the rd done.
