I have a line on a 1999 X1. 1600 miles. I will only consider buying it if I can figger out how to switch it to carb. Is the F.I. system and related components of any value to anyone? Also a link to any articles on the swap or component suppliers would be great. Thanks | ||

carefully remove what you dont want. Yes you can get some money out of throttle body and fuel injectors, everything else, hell they in like new cond but old. Just keep everything together and list here first in classifieds. | ||

You may want to keep the fuel injection. It is easily tunable with the ECM Spy program. I have never had a problem with mine, 34 K miles. Check some posts about others who switched. Some went through much trouble to do this. You will enjoy this bike! | ||

Berni, you have to replace your manifold first then a Mikuni 42 works very nice accompanyed by a Forcewinder intake, then the only thing left is to get rid of the ignition system by installing a Daytona ignition system. Now you have a totaly mechanical X1 and you can scrap that ECM (personally it was a very emotional moment for me)! | ||

Bikerjim99 and Jstfrfun; interesting perspectives both. I also have a Cyclone and just prefer oldskool, irrational as it may seem to some. I did some reading on the ECM Spy and quite frankly, I'm WAYYY out of my element. Jstfrfun; can you elaborate on your last line. It sounds like getting rid of the ECM was very important to you. | ||

If you understood how a combustion engine works, you will easily understand how FI works. If you didn't understand how a combustion engine works, you will never understand how carburetors work. Regards, Gunter | ||

Change over to a carburetor is simple. I also recommend you change to nose cone ignition. The biggest problems I had with my FI Buells has been the wiring. HSR carburetor and crane ignition will fit your needs for most application. Joe | ||

I have over 25K on my Xi and can't imagine going to non EFI. I would think the power and response would go way down. I have the Buell race module in mine. The only issue I've ever had is the TPS. Simple fix though. Just my 2 cents. Nice and easy to see the trouble codes also if there is a problem. Old school is just old! | ||

HHhhmm. I think you are right about the loss of power if you go look a this same motor at a carb stand point it is not as powerful or effient as a efi at making horse power. I have seen carb models hit what the fuel injected buells get stock, After significant motor work. Here is a link look for yourself!! http://www.nrhsperformance.com/ekitevbt.shtml Now i e-mailed them and asked what i could get for the 01 x1 and they said the 1250cc kit could yield anywhere from 15+ to 20 more rwhp to my FI bike. You be the judge!!! (Message edited by preybird1 on October 07, 2008) | ||

Why fix something that isn't broken? Buy it - ride it. If the FI acts up we can help you fix it. Don't worry about "learning" ECMSPY, just read and try to understand how the FI operates - it really is not that complicated. Plenty of us don't really understand how a shock works and even fewer of us can work on our rear shock - does that mean we should turn our bikes into hardtails? I believe the owner of a bike can do whatever he wants to it, but I get a little sad when I hear about another FI bike get downgraded to a carb. | ||

Downgraded is right. These conversion are motivated by fear, and accomplished with ignorance. I'd rectamend keeping the FI. I've NEVER had a problem diagnosing or fixing an FI bike, and once fixed, they don't come back. (Usually, I end up fixing what other people have hacked...). I work on carb'd stuff all the time, and they seem to need something every so often. Tens of thousands of XB's, with practically identical FI, can't be wrong! | ||
| Jos51700 |
And honestly, if you're smart enough to remove FI stuff, and fit a carb, you're smart enough to repair the Buell DDFI. | ||

I don't believe that fuel injection makes more power. It is more efficient and more adaptable to changing condition than a carburetor. But the carburetor requires less power and is less likely to leave me stranded on the side of the road. That is my experiences with Buell motorcycles. I would not change from Fuel Injection if it is working correctly. But I have to wonder why the need for ECMSPY or other systems to calibrate the FI and sensors. Also there is a large after market supply of parts for this conversion, I don't believe that the majority of conversion are people that just don't like Fuel Injection. If it worked well I believe it would still be on the motorcycle. Just spend sometime in the XB section, 1125 section and other boards just a lot of time wasted when all we are doing is riding on the street. Well just another opinion form the frightened and ignorant. Joe | ||

FI doesn't make more peak power, unless the throttle body is bigger. However, it makes more power across the board due the tighter control over air/fuel values, and the ability to give more air/fuel sooner (Like, buh-bye CV slide!) ECM spy is needed just as screwdrivers, and wrenches are. It's another tool for a new part. That's all. Don't worry about being frightened and ignorant, Joe. I'll protect you  (I guess I should clarify, people that remove a perfectly functional FI system because they're afraid of it, and aren't willing to learn how it works, so, I really wasn't meaning you) | ||

BAD ARSE "FI" = max. throttle body, best fuel injectors, and a GEEK LAP TOP "TUNER" !!! | ||
| Jstfrfun |
The conversion I did was to a 2K X1 for stand alone use (Jos51700 almost put out a contract on me for it)in a modified chassis. The difference I found was simplicity(no need for a computer) and a real hard hit off the bottom. The bike I'm building will not be a everyday driver but a show bike...with 110 horses! I still have my 99 X1 all intact with the computer system. | ||

"Jos51700 almost put out a contract on me for it" Will never happen to another Bueller, only JapBikers. | ||

ECMSPY replaces jets, clips and needles, a laptop replaces a dyno because you can datalog. Some FI bikes run poorly from the factory because they are trying to satisfy the EPA, try to get them to pass with a carb and they would run even worse. Modifications can be made to the FI system to help make any reasonable power the engines are capable of producing, including 110 HP. Name a single motorsport class where FI is legal and top competitors use carbs instead? Many guys who prefer carbs because they are "simple" don't understand them either but either buy one that is already setup to work or can fiddle with jets and settings until it runs reasonably, not because they actually know how to tune one. Go to any older bike forum - all the chatter and problems are with ignition and carbs..... |
