these bikes are a labor of love

i have found as far as others say you might not need to reprogram the pcm. especially if it runs good and already has an aftermarket can on it. I can only assume cause these bikes don't sound good...

rotated my engine to replace base gaskets last night, pretty easy stuff and you don't even need to drain the oil. anyway I'm still looking for advice as far as how to get my hands on a new ecm for my...

my only goal is to get rid of my wot power loss.my bike always ran great. others on this forum recommend I try a new pcm as I have no codes stored when doing the manual code method but when I use ecm...

ive had an offer for 300 for a tuned ecm. person states its been tuned for hawk exhaust and open air box, which is what I have. well not sure about the can but I know its aftermarket. plus shipping...

and remapping them isn't a big deal? id like the plug and play of a race ecm and im nervous about attemping the reprogramming with the ecm spy. am I worried for nothing?

How much and does anyone have one they can sell me? 03 xb

I hope you find your problem easily. I wonder if the ecm has stored codes? google how to check for codes on the buell xb and take a look or buy a service manual.

I did do swing arm bearing too.

as you can tell, I don't want you to be right but its looking that way. after repairing the worn line with some contact cement and installing the bad one on the rear where there is a lot more...

after I get it back together ill let everyone know what I find. so is chaffing in this area normal? my xb firebolt used to be a lightning fyi and when I first got the bike I noticed the front spark...

u think full throttle at neutral would over load the fuel system? I did check the fuel pressure and it read 50 psi and the needle was just a bit shaky. as stated in the factory manual I revved the...

dayum looks like hes got you covered, lucky!

my low fuel light came on so I decided best go get some premium and do more test riding. after a normal ride to the gas station I filled her up and hit the access road. I nailed it and bike fell on...

I've put over 4000 miles and 4 track days without changing anything. I bought the bike with that ecm in it. It is the for race use only Ecm. Ecmspy shows it as Buecb and that for an 03 Xb. Unless...

I found some stuff on the amc but they were not selectable. I did find something that was selected that was labeled something like a full throttle limiter??? lol I deselected it and will test ride...

this is the same ecm its always had, and ecmspy shows the ecm is for an 03 xb. active muff control, like the xb12? it is a race ecm and says "for race use only" thanks for that info about AMC. let...

also found codes 21 amc stuck open, amc stuck closed. noting in the manual about dtc 21

being that you are a noob I would only recommend you adjust the clutch cable, lubricate the cable change the primary oil and adjust the primary chain. that's about all you can do without teardown

my girlfriend who is much better with computers got ecmspy working. while she was doing that I went and got my money back from Harley.

I found that my tps wasn't set properly and that was...

yall still there or am I talking to myself? I managed to reload ecm spy and now when I hit the icon on my desk top a screen with boxes comes up but nothing else happens. about all I was able to do...
