Bitch be gone then.

If you can squirrel away a few bucks here and a few coins there, she may not find out.

Until you hammer the throttle and she flips off the back. (smoothly, of course)       

Flash or not I know better than to hammer the throttle with her on the back. My wife most certainly DOES NOT EVER feel the need for speed on the back of my bike. In fact I've had to promise to ride somewhat sedately whenever she's riding with me or she refuses to ride at all.

She wanted me to buy a HD so that I wouldn't ride so fast.

I tried the HD thing for the same reason. She liked it til I ran out of ground clearance.

Ooooookaaaaay, back on topic!  Just a quick update...the 2k RPM cold idle only occurred for the first three cold starts.  All subsequent cold start idles are back to where they have been for the past several years.

See what happens when you leave us unsupervised for a couple days?

[VirginiaJim]

There was no lack of supervision.  All went as planned.

Mine didn't do that but it was 87 degrees when Steve did the work and I tested it, maybe that had something to do with it.

Cold idle doesn't have anything to do with the flash, same as the lousy fuel economy the bike gives riding in the cold. there' an atmospheric sensor and coolant sensor that feeds back to the ECU, cold weather, altitude, barometric pressure all impact how the fuel is trimmed by these other sources. The coolant sensor is primarily what drives the cold idle to be higher. This doesn't have anything to do with the flash. Steve

Wow so much to learn.Got my new bike just 3 weeks ago (2009 Model with Two Brothers slip on).Previous bike was a 1991 Suzuki GSX 1100 .So this is my first bike with EFI.I have rode the 1400 for about 500 miles in the last 3 weeks and have noticed all the little quirks mentioned in the review at the start of this thread.I was wondering if i needed a Two Brothers Juice box but from further research looks like a ECU flash may be the way to go.

Get a ECU flash from Steve & forget about all the other crap !!

Best $300.00 you will spend on this bike....

[kb9ndl]

Thanks guys for your advice.Rode 125 miles today at 45 degrees.With the right clothes its not cold at all.

I'm late to the party here, I have a 2012 with a Guhl reflash which I liked for the low end power add.  I do still notice a huge clunk when I transition from off to on throttle.  My bike sees redline a fair amount, so I am interested in the big hp increase, also for the smoothness and especially for the mileage increase, my bike seems to get very bad *ahem* mileage.  My brother has the same bike and is on here sometimes, he loves it and swears I should get it and he knows I have the Guhl flash. 

But one thing I saw and I only saw it once, was that somebody said you can run 89 octane with Steve's flash?  I only saw that once and mine sees WOT at low rpm so I notice that would make for a lot of detonation if the octane was too low.   That's not something I would want to risk unless I was pretty sure it was ok, so that's what I am looking for here.

So what's the deal, can you run 89 with this or what?   Between a mileage increase and the price delta between 89 and 93, this thing could help pay for itself.   

Thanks

    I'm thinking I am the best to answer here. Yes, I built the flash on 89 octane, on purpose, it was done so that if the various tuning parameters would work with 89, higher octane, 91-93 just adds a margin of safety, so I suggest that a person follows the recommendation of 90+ octane from Kawasaki.
 
   Also, the issue of wOT at low rpm is important . Obviously there's a pretty large difference in load between wot / 1st gear 3k rpm, and 6th gear, 3k rpm. So to just say the issue is WOT low rpm doesn't really provide enough info. Regardless, I know there's somebody out there who will pull WOT at 2000 rpm in 6th gear, so yeah, I did it while tuning repeatedly to be sure there's no gas knock. Do I think it's a good idea on any engine? No. Do I recommend it on a stock tune? No. Do I recommend it with my tune? No. High cylinder pressures at low rpm and high load is very tough on the engine regardless. But the fact is I did allow for that while building the flash, and I did back off some parameters to be sure there was no detonation, on my bike, with 89. 

   All that said, WOT at low rpms  high load will just never be a good idea... that's what a gearbox is for. Steve

Lots of great info here.  Hopefully I will get mine done before tax time.  Stock is linear, but doesn't pull like a 1400 cc bike should.  Everything I've read tells me that the flash will give me the bike I paid for, for only $350 more.   tp
