I had my 2007 s4rs with full Termi exhaust (new ecu filter header) on a dyno this weekend and it reported 121 rwhp. I was expecting something in the high 120s but definitely not as low as 121. This dyno test was a freebie put on by a local dealership so I didn't get a print out or to talk to the guy doing the testing. Other people had their bikes dyno tested as well and experiences similar results/feelings to mine. Any ideas? Does this number seem on par? BTW- after the dyno I noticed that there some black residue on the slip ons that I've never seen before. I do remember some black smoke coming out during the dyno for a second, but I saw this on about 10 of the other 25 bikes tested. Any thoughts or ideas are very much appreciated,Dyno's are not zero'd out across the board, each one is a bit different. It's a tool for measuring losses and gains, nothing more. Pretty obvious by what you said that the dyno might read a tad lower than others. Nothing to worry about whatsoever.,,,

How do I Reprogram ECM with Screamin Eagle EFI race tuner kit (pn 32107-01E) WITHOUT DYNO.


You can use a laptop or desktop computer to reprogram the ECM. If you do this, you will be changing the maps in the computer. The maps may or may not properly tune the bike, depending on accessories such as air cleaner and exhuast, and what modifications, if any, were made to the engine., Dyno tuning is the way to go. It monitors air flow, fuel flow, exhaust gasses, etc. Air and fuel can be added and/or deleted from any part of the map for the most efficient operation. Not using a dyno is just guessing and you could make the bike run worse.

My local HD dealer just installed a HD race tuner, a air cleaner kit and a set of Vance+Hynes true dual exhaust and dyno-tuned on my 2008 Road Glide, $1600.00 parts+labor . I bought the bike from them used...


Take it to another dealer. Dealers usually will not warranty any type of performance work. I find it difficult to see why the exhaust would cause the vibration. Just make sure the exhaust is supported properly to the frame. I would however suspect the race tuner. If the tuner is not adjusted correctly it will cause the engine to run poorly. It may even cause the engine to overheat. I'd suspect the igniton timing. Take it to another dealer or to an aftermarket that has a "good dyno man".

Now, there are two types of dyno-tunes. One, is actually not a dyno tune but more of a dyno run up. Regrettfully, this is what most dealers do. They install a bunch of stuff and then put your bike on the dyno, run it up, and get a print out of the horsepower and torque, that's it. This is simply a run up. The charge us usually about $35 - $50 or so.

Now a true dyno tune is totally different. The run up is just the beginning to establish a baseline. Then changes are made to your race tuner, intake, fuel map, timing settings, and exhaust to get the highest horsepower and torque out of your bike. You are usually charged "X" amount of dollars to begin with and then some much per hour. I've seen a good dyno man work on a bike for several hours changing jetting and such on the bikes and believe me, if the guy does what he's supposed to do, you can feel the difference. Bad part is a "good dyno man" is very hard to find.

Good Luck

I have just redone my 2007 dyno bmx bike and I was wondering if I could swap parts with other bike parts


Some parts, you can. It depends on what parts and what bikes, and noone really has an all-inclusive list that I've ever found.

Best thing to do is measure up the part you want to replace, then check for parts that have the same important dimensions.

Dyno mountain bike with a braking noise


If it is when you pedal, check the bottom bracket (where the cranks are attached) The bearings might need changing which would cause the noise.

Do the handlebars rock back and forward, if so, check and tightent the headset, check the bearings inside if they are dry or broken, replace and re-grease.

Underperforming catalist


readings taken downstream (exhaust) with the O2 sensor are telling your computer that the catalytic converter is not doing its job well enough (it is reading too high an exhaust content of carbon monoxide or hydrocarbons) the solution is to replace the catalytic converter assuming the engine and its other management systems are performing healthy ....good luck
