I have been making the RAIS Power Tubes going on 1.5 years. The only place that I sell them is on eBay as it is the easiest platform for me to function on. What I am trying to figure out is how you heard of an RAIS Power Tube and why did you buy it? Were you just cruising through eBay and saw it? Did you read about it on a forum? Did someone tell you about it in the desert? I realize that this modification is pretty basic and certainly not for every Rhino owner. Some people swear by the RAIS Power Tube and others put it down. One forum owner bought a brand new dynomometer for nearly 20 grand and one of the initial things he did was to 'test' the RAIS Power Tube on his new dyno. He then posted that the RAIS resulted in a power loss when installed. It was not mentioned that no jetting assessment was performed and he eventually backed down but regardless, he said what he said. I have to wonder what that is all about. I have had a lot of fun making these things and talking with various Rhino owners around the world. It's safe to say that I will continue until sales dwindle. I'm just thinking out loud. I have had a huge week of sales and I'm trying to figure out why. I see the info about the jagged x rhino crash event just held. What kind of exposure would a modification such as the RAIS Power Tube have at an event like that in my absence or absence of any promotion or advertising so to speak. I'd appreciate any of your thoughts. ww  Roostin' Rhino RAIS Power Tube    Report

I bought the RAIS power tube,the 155 jet,and installed just like you said. I instantly felt the power difference . Your power tube, along with rejetting and turning the air mixture screw out to two turns is the only mod i've done yet. If I were to only do one thing, this would definately be it. I dont know you from adams house cat.I have never seen or met you.So I'm not partial to you or your product.The fact is it works.Plain and simple.I will be telling other rhino owners about the power tube for sure.I saw it on ebay,questioned you in the "ask seller a question",and I bought it.The rest is history.Thanks for a awesome product,Scott.    Report

The seat of the pants dyno is the best test imho. I have the rais tube dynatek cdi larger exhaust tip and I've rejetted. My rhino runs better than it ever has. The forum owner you speak of is ok,he just speaks to fast I believe~!    Report

I also appreciate Bill, the owner of this site, to allow me to capture some of these opinions on this platform. I have spent a good deal of time on other forums defending the product and I simply don't want to give the impression that I am promoting the product on their buck. On here, the opportunity was presented to me. Regardless, I appreciate any and all opinions on this product. It is becoming very, very obvious that I really don't have a clue to just exactly how many Rhino's are really out there! ww Roostin' Rhino RAIS Power Tube    Report

Based my decision to buy the Rhino in reading some forums (Just bought a 07' Sport 2 weeks ago - just got it dirty for the first time yesterday :) the wife and I love it) In my reading I ran across this site and was impressed with your contributions to tech issues - especially jetting. That is what impressed me the most - knew the RRR Power Tube was my first performance upgrade. I am anxious to ask your opinions on some complimentary upgrades - will do that in another thread.    Report

Here is a cut and paste from the engine mods folder...We were discussing most cost effective modifications. Free > Adjust your a/f mixture screw for correct idle and transition off idle. 1. 0-$10 > rejet with a main jet appropriate for your altitude, shim the jet needle and run without the o.e.m intake snorkel. 2. $10-$50  > do #1 mod and install an RAIS Power Tube which replaces the o.e.m. intake snorkel. 3. $50 - $100 > do #1 and #2 and install an aftermarket air filter. 4. $100 - $150 > do 1 - 3 and install an aftermarket exhaust tip. 5. $150 - $200 > do 1-4 and install an aftermarket jet kit which has a jet needle with a different profile and a lighter wound slide spring. 6. $200 - $400 > do 1-5 and install an aftermarket cdi. its an instant 10 mph even if you do it first. 7. $400 - $600 > do 1-6 and install a grizzly sheave or an aftermarket sheave. much better 'cruiseability'. 8. $600 - $1,000 > do 1-7 and install a full exhaust. I wouldn't recommend grinding the exhaust manifold welds as it is only marginally effective and much more can be gained by a full exhaust. 9. $1,000 plus > sky is the limit and no need to go there. For $600, you will be very happy with your low to mid range performance. Of course, I'm partial to the RAIS Power Tube since I am the one that makes and sells them but it is what it is and it works. For what it's worth, I still am running the original prototype RAIS Power Tube on mine. If it didn't do what it was supposed to, I wouldn't have it on there. You can mix and match any of the mods but I feel to attain the most cost effective performance enhancers in the power delivery range that you are looking at, the order should be followed. Some may also suggest clutch kits would accomplish what you are looking for. I don't have any experience with clutch kits so any opinion would be speculation. A clutch kit doesn't add power, it simply modifies the way that existing power is delivered.  I hope this helps. ww   Roostin' Rhino RAIS Power Tube    Report

William I first saw your product on this forum and read quit abit about it and then I noticed it on E bay. Of course I asked the seller a question or two and you were very helpful. You could just power sell your product but I think your in it for the long haul, by suggesting Jetting etc. that shows me and others you care about your product and you are not just in it for the quick buck and walk away. Your product works with the modifications you suggested, I have not seen any other product like it on any other sites and believe me I've been surfen the web.Thanks again for your help.    Report

04-23-2007, 6:29 AM fasttrax Joined on 08-03-2006 West Jordan Posts 126 Re: Roostin' Rhino RAIS Power Tube ??? I finally have it running with only limited exaust back firing on quick decel. What causes it to die on quick decel? I usually need to choke it without throttle to get it to start after it dies. I have been at different turns on the mixture to limit backfire at about 2 1/4 -2 1/2, running a 145 main, needle shimed, 45 pilot. I have read I need to go up on my pilot again any suggestions?       Ryan    Report

Given the problems that you have experienced regarding tuning, I would suggest the following again if you have not already done it. Replace your plug and disassemble your carb and blow out all jet circuits (with jets and screws removed) including the decelleration enrichening circuit. I would reinstall the 40 pilot jet. Make sure all of the components are there. Validate the float level. Change the fuel filter. I would then adjust your a/f mixture screw to max 2 turns out. Then I would ride and assess the running condition of your machine. I think you may be trying to correct to many running issues at the same time and think that it would benefit you to get it back to basically a stock configuration and then go at it one step at a time. Set your idle correctly first. It should end up around 2 turns out give or take a quarter turn (sounds like you are there). Leave the 40 pilot in and shim your needle for best acceleration. Finally install the main jet that gives the best top end speed and all should be good with no backfires, pops or anything. I assume that you have checked thoroughly for cracks on your exhaust (they can be small and hard to see). Alternatively, you can try a larger pilot jet if that is what you believe to be the problem but I would be very surprised if this improved your condition. ww   Roostin' Rhino RAIS Power Tube    Report
