Yeah I'm out a decent chunk of change because of them. Their master clips fail all the time, smart 2 chains spit rollers after a few thousand miles and sprockets are made of butter. Huge waste of money.

If you have ever stumbled across this page, http://sidewindersprockets.com/ Their advertising looks too good to be true, and apparently rightfully so... https://www.facebook.com/pages/Sidewinder-Sprockets-Failures/715008641920953?ref=aymt_homepage_panel (Edit) I'm out a decent chunk of change because of them.

If you want to ride the bike how the Honda engineers designed it to be ridin, put a Rapid Bike Racing module on it and install the optional 4 wide band o2 sensors. The included base ignition and fuelling map will get you pretty close to perfect and after about 200 miles you'll swear that you have never riden anything so smooth in your life. The VTEC transition, snatchy throttle and surging completely disappear. Also the ignition remapping adds a significant amount of low end and midrange torque everywhere and the engine braking adjustment feature gets rid of the factory fuel cut that you were talking about.

So over the last 24 hours I fitted the overbore throttle bodies and boots and port matched the heads to them. Here ate my updated maps. It is up about 20% more fuel everywhere over my last map that had been made the day before. I would ignore the 0% column. I need to sync the new throttle bodies pretty bad so the 0-4% fueling is off.

Here you can see the advantages of having four separate wide band o2 sensors and individually tuning each cylinder. Notice the different fueling demands of each cylinder by wide open throttle and red line. I have put about fifty miles on the bike since installing the four o2 sensors. I can not emphasize just how unbelievably smooth the bike is now. The VTEC transition has literally disappeared. It is now just a change in tone and there is no dip or surge in power what so ever now. I have only put an hour or so of seat time on the bike to allow self tuning and I can say right now for a fact that I have never felt a bike this smooth with such a linear power band before in my life. Being that I still have not even swapped the new injectors/throttle bodies or ever even synced the stock throttle bodies or adjusted the valves etc yet and I have 61,000 miles on the bike now is just mind blowing. I can not wait to get the new injectors and throttle bodies on here and then sync those and let it tune for that.

Before and after Rapid Bike racing dynos of a 100% stock 2003 VFR800, tuned using the 2 factory narrowband o2 sensors. Keep in mind that this is with no other mods, not even a slip on or air filter. The improvements should be much greater on modified bikes or in the case of tuning each cylinder independently with four o2 sensors. That is before and after at 100%, 23% and 13% throttle positions. On the 13% throttle you can see the dramatic breakdown of just fuel corrections alone and then the added benefit of tuning the ignition map on top of the fuel map.

What's the price difference between buying from dimsport or buying from Cordona??

I can't recommend Sato GP shift rear sets enough. One of the best mods that I have done. Well worth the money. And I wouldn't recommend the quick shifter with out them.

What's a 75 s3 ?? This is a 75 S3.. I'd say five minutes tops while windows 7 updated the rapid bike driver etc. Yaman told me that they are releasing a new update soon for windows 8. I am not sure if windows 8 and rapid bike are working together or not but my windows 7 is fine. You may need to click on the updates available icon in the bottom right of your computer screen before your computer recognizes the rapid bike.If you still can't figure it out, call Yaman at cycle pro.

Oh cool 2007 Honda VFR800 with Rapid Bike Racing module: http://youtu.be/BUhedrdScX0 Sorry its crooked Rapid Bike Racing VFR800: http://youtu.be/tCcSIuevMJA Or upside down

Rapid Bike Racing software 3: http://youtu.be/-dJNgSe6Py0

I just got my rb racing to connected to my laptop. It took a little while for my laptop to "install the rapid bike device driver" or something like that with it plugged in and bike running, but after it installed the device software I was able to click the get map button and everything connected fine.

What's a 75 s3 ??

boOZZIE what year are you??

I think I'm going to have to start saving up lol

Hey guys......

The rapid bike racing quick shift mechanism is of the digital strain/stress sensor variety. It is not a simple on / off switch like most other units. Because of this, I'd say that the quick shifter is going to have to be rapid bike specific.

I'm running four at the moment. I always run 93 but have tried 91 before and noticed no difference. With that being said, I would only run premium fuel, just to be safe.

The Fuel and Ignition Maps are here and ready! And holy crap that looks like 5 degrees of ignition timing advance on top of the factory timing curve. THAT IS A LOT MORE THAN THE OLD RAPID BIKE 2 AND 3 MAPS THAT I AM RUNNING.

I want to say with the Rapid Bike 1 it is fuel only (in 4 cylinder applications) Rapid Bike 2 it has fuel control plus either ignition advance or rev limit extension (not both at once) Rapid Bike 3 has the ability to hold 2 fuel adjustment maps plus hold two ignition adjustment maps (so you can has an ignition advance map and have a rev limit at the same time or have two separate ignition advance maps)

Do you have any idea on the weight difference between the rc45 swingarm and the VTEC swing arm?

Check it out. From Yaman: "Finally the VFR is in the applications list, please note that you will not be able to raise the RPM limiter with the free version on the software, however, if requested, I can do it here with our software before shipping it out to you guys."

Awesome!!! Have you thought about lowering the compression ratio or using methanol injection??

sixth gen vfr swing arm?

I know what you thinkin " GROUP BUY" !!!!!Haha naw I'm pretty committed to rapid bike. Plus I can't live with out quick shifter lol
