I have a quick question. I just got an RPC Stealth Pipe for my Phazer from a friend. He doesn't remenber jetting or clutching specs for it. Does anyone here know them? Has anyone here used this pipe? How much more power will I get from it. The phazer is a 1986.
hmmm, sorry, I have never even heard tell of them before. The best thing to do is try to contact the manufacturer. Search on the net for the manuft. and try to find a number, then go from there. Sorry i couldn't be more help, I know what its like waiting to get an answer. Good Luck with it.
I wrote to the editor of the snomobile online section of offroad.com and he helped me out with my xlt. Try writing him. If I find anything about average jetting changes for your slead I'll reply and put em on here.
Go up two sizes from stock jetting and work your way back down if necessary. I have never heard of this manufacturer but they should be close to Aaen specs. Install a Red-Blue primary spring (part no. 90501-55343-00) for lower elevations. Aaen produced an extra 14 Hp with their pipe. When you are piping a Phazer make sure you do the primary nozzle mod or you will burn down in the midrange. Here is a copy of some of my notes on piping a Phazer.
For single pipe change the primary nozzle to part no. 80L 14489-00-00. This nozzle has a thru hole which allows the nozzle to draw more fuel to enrich the midrange operation of the carb. With a pipe it needs more fuel in the midrange or lean seizures result.
A different main nozzle part no. 8Y2 14941-2A-00 may also be put in but I found it to cause a bog off idle. It's purpose is to enrichen the carb just off idle somewhat. I think this mod is mainly for a big bore engine and not required for the normal 485 cc stock engine.
RPC stands for Richert Performance Center. If I remember correctly they are in Wisconsin (Milwaukee??) I looked and looked on the net and never found them. I stumbled across their address by accident but can't remember it for the life of me. Hope this helps....
Sorry for the long delay in a reply, I ended up getting everyting dialed in real good. I ended up going from 95 on the pilot to 110 and 143.8 to 150 on the main. I also did the primary nozzle mod and everyting seems to be perfect.
What's the RPC pipe sound like? I have an AEEN on my 91 and it sounds I guess what you would call "throaty". Several years ago when I was riding Deere's, I had two Phazers go past while we were taking a break and they had the sweetest "buzz" to them. I ask around and most people thought it was probably an RPC pipe. Just curious....
I guess you could say it is more of a buzz. Higher pitched than stock, but it is loud. Overall, I really like the sound of it. I just hope that I don't get a ticket. [img]images/graemlins/grin.gif[/img]
