I replaced the K&N air filter with the stock air filter and ran redline fuel injector cleaner thru the system. New result is 157.87 hp @ 92.61 ft/lbs. (higher ambient temp /lower humidity) When I changed the filter, the idle dropped, and I had to adjust the idle up to keep it running. I would think this is more restriction? The dyno shows the bike is now running richer than with the K&N filter, but producing more power?? People have suggested dyno tuning the bike, I wanted to get yor input before doing this.
Why does my bike miss and not idle below 5k after I installed the exhaust, PAIR block off, and air box mod?
I have an 05' Hayabusa with Brocks Air Lid and P.A.I.R. block offs. When I installed the block offs the bike would not stay running at idle and seemed to run rough. I purchased the Power Commander III and hoped this would solve my problem. Unfortunately no one seems to have a map for a bike with the PAIR valve removed. What am I supposed to do? I was trying to avoid taking the bike somewhere to have it dyno tuned but if I cant find a map this is my only option.
I just put my ZX-14 back together. The head is ported by Spaz and I degreed the cams. Also has JE 13.5:1 pistons and Carrillo rods. Smeg, flies out, BMC race filter. I put the SS map you sent me in and used 93 pump gas. It starts and idles great but I tried to take it for a ride and it was bogging and dying on me bad. I thought it was too rich, but pulled a plug and it was very clean, looks lean?! I am just trying to convince myself there's nothing wrong with it and it just needs mapped. Is there anything else that could be causing this that I can check.
I just installed Brock’s ShortMeg full system with the PCIII on my 2008 Hayabusa. Install went very well and runs great, no backfiring etc. But the one issue I do have is the idle now pulsates from 1100 to around 1200 or 1250…just a light bounce. It was very steady. Is this an issue? Is the map the correct one?
Are the three buttons on my PC3 USB for increasing RPMs at idle, or should I leave these alone?
Why does the idle increase after about 10 minutes of riding on my 1361 Hayabusa with basic head clean up and Alien Head system?
My bike is stalling after a burn out, at stop signs, and at the end of the track when I'm slowing down ... do I need a new map?
I have a 2015 zx14 with full alien head , pcv , and guhl flash ( only 260 miles on it ) and a 2013 zx14 with full alien head , pcv. Both are lowered and are pretty much identical. But the 2013 seems to be running a bit crisper per say vs the 2015 . Another point is I had a 2012 with the same setup and it runs like my 2013 , you start up and it idles a little rough ( up and down) but smooths out . The 2015 starts up and runs like it did stock , my question is , did they change or add something that I over looked ? The 2015 seems to be running a bit rich also ? It just don't seem as quick as my other 12,13 did.
