Meat Posted September 2, 2002 Report Share Posted September 2, 2002 I have a set of stock bore, stock ported RZ 350 juggs. I cant decide if I should have them ported or not. What would you do ??? Quote Link to comment Share on other sites More sharing options...
bansheerabbit Posted September 2, 2002 Report Share Posted September 2, 2002 Hi meat, I just got back my RZ barrels all ported and it has made a huge difference - lost a bit of bottom end but gained in mid and top end power. Just so you know the barrels are back on the road bike for further testing and fine tuning before installing on banshee. I was told that the standard barrels of the banshee can be ported to produce more power than the powervalved system due to the limitation around the power valve (not being able to take as much out) so Ive got my std barrels being ported now. Go ahead and port them you wont regret it. Regards Rabbit Quote Link to comment Share on other sites More sharing options...
Aussie Quad Racer Posted September 2, 2002 Report Share Posted September 2, 2002 Hey bansheerabbit. How r ya? Im from QLD. Who's doing your port work on the barrels? Quote Link to comment Share on other sites More sharing options...
-Turbo- Posted September 2, 2002 Report Share Posted September 2, 2002 Meat, I would for sure port, nothing wild, maybe only casting flaws and some slight transfer work. ONLY use someone that has done alot of the RZ's. Quote Link to comment Share on other sites More sharing options...
Bologna Posted September 2, 2002 Report Share Posted September 2, 2002 Meat, You'd be all set if you could get Stuart Toomey or Kenny Roberts to port your Rz jugs. Bill Adams porting is keyed toward the RZ porting schemes too. Quote Link to comment Share on other sites More sharing options...
WickedBanshee Posted September 2, 2002 Report Share Posted September 2, 2002 leave em stock for now. try them out before you port them. im sure porting will happen someday but would you rather have a banshee in stock form and then get it ported or just have a ported one to begin w/ ? i'd try the rz engine out before i'd do anything to it.

glock221 Posted September 3, 2002 Report Share Posted September 3, 2002 I myself would leave em stock for a season or 2. Then when you redo the topend, I would port. Quote Link to comment Share on other sites More sharing options...
Backcountry Posted September 3, 2002 Report Share Posted September 3, 2002 PORT PORT PORT PORT PORT!!! Sorry... well not really... The exhaust duration of the RZ cylinders are plenty for any Banshee pipe, the width is decent as well...The transfers and intake need some work.... Transfers- reshaped, cleaned-up, and some more duration- not much just a lil- that will broaden the mid range more and mellow out the curve to be broader and smoother- peak power will pick up too.... Reshape the intake for better velocity... Get a good head set-up, good cages and right sized carbs!!! She'll rip!!! Oh yeah btw.... PORT PORT PORT PORT PORT!!!! -Dan Quote Link to comment Share on other sites More sharing options...
Meat Posted September 4, 2002 Author Report Share Posted September 4, 2002 thanks for all the advice. Id like to see more votes and hear some more opinions on this as im still undecided :roll: . One one hand, I have these almost-virgin RZ juggs and it would be cool to leave em stock just so I can feel em' out, and the next rebuild have them ported. If Id leave them stock now, once I eventually do have them ported I would appreciate the porting work more....... but on the other hand I know i'll want more HP and it could be a long time before the juggs are off again. Can anyone else sway me in either direction? Any other reasons why I should or shouldnt ? BTW, im going to build my RZ-Shee this winter and I'll prolly have a few more of these "poll/threads". Quick....er balony....... Bill tole me once that he picked up alot from some RZ roadracing guys he knows, or knew or something. Do you know if Bill is still porting cylinders, I think he's very busy with his school work. Id give him my business again, cause my past porting "transaction" with Bill was great, everything from email support from Bill, to the seat of the pants kick ass powercurve he ground up for me. He did alot of extra work for me because of the resleeving, he arranged for his machinest to install the new sleeves and did alot of work buildingtransforming my transfers. Do the big name Banshee engine builders port RZ juggs ?? For example im thinking about Ohton, maybe Dave Moore, maybe FSTRNUGRR. I would also trust BackCountry with em. BC got any "hands-on" RZ porting experience 8) ? Quote Link to comment Share on other sites More sharing options...

Bologna Posted September 4, 2002 Report Share Posted September 4, 2002 Meat, Yes, BC does have experience. He was telling me about an RZ 350 he did for a kart guy. He ended up winning the championship. Spun 11,000 rpm all day long...no probs. As for bill, i know he just recently started med shool. Im sure hes busy. However, for you, im sure hed try to work something out. Yep, hes big with Dale Alexander, and Stuart Toomey, who originally started on RZs. Cant go wrong with either of the two. I am not aware of any RZs built by the other big guys. If you need BCs email, pm me, ill give it to you. Looks like he started his post while i was typing mine!!!
