I doubt there is really any other advantage over hemispherical heads other than getting to say you built custom toroidal heads
teazer said:On a street motor I think I'd optimize MSV in the squish band and go with a conventional hemi head shape. Peg the heads to the bores and seal them with TZ O rings

Thanks a million man, I may hit you up sometimeRedbird said:Subscribed.
I've got odd and end spare parts from my DS7 build. Holler if you need anything
teazer said:What's up with that pipe? It looks as if it is very low compared to most RD pipes. It could just be a badly shaped header pipe.
I should change the title of this thread, the frame is rd350, but the motor I'm using will be the piston port r5 motor. Thanks for all the great info though!davedogg said:My RD's are very reliable and enjoyable. Stock is fun. I've taken my modified 350 and stock 400 on 100 + trips. But there are simple add ons to unleash some power. My experienced tuner just rode my bike the other week and was impressed (so I know I did things right) This may be overkill but here are some performance mods I did to get you started:
2 into 1 K&N Y boot (more air) ~$90
Dave F/ Dale A carb mod (more air needs more gas) I'm not an expert. I just know it works.
RZ/Banshee crossover manifold and tube (erases flat spot around 5k) ~$50
YZ125 Reeds petals (consensus for better low end torque) ~$40
Heads squished and o-ring (better compression = more power) look up Scott Clough Racing ~$190
Good set of pipes. DG's are ok. I would get SpecII ~$500-700
Using both Wiseco (forged) and ProX (cast) pistons I like the ProX more. I'm sure there is more but this is all I can think of off the top of my head.
