I posted on another forum but no real fix so here goes. just got it started and it runs like crap should I start with the plugs? I cams fell out when I removed the cam cover to have it painted but I'm pretty sure I put them back in just fine. it ran good cold, seems to run on one cyl ? I did the tps reset , and no codes except code 21= exhaust valve. when I test the injectors they click . anyone have this happen? here is the vid I took of the ecmspy https://www.youtube.com/watch?v=F4RqfpAu1PU anyone got an idea (Message edited by 04mx on May 23, 2015) | ||

well put new plugs and bike ran good for a few minutes (I think) no backfire or coughing in the intake. after that it started to run a little rough but still not as bad as on the vid. thing is I just got the bike ,I haven't even ridden it yet . I brought it home this winter and disassembled it for paint. the bike had 1 HD #10 plug in front and a NGK #9 in the rear (wtf) is it normal for the exhaust to get a faint glow at idle? and I checked the compression and on my gauge is says 120psi front and 125-130 rear is this right ? I checked the cams and they are spot on . installation is almost foolproof you lineup the crankshaft tdc mark in the plug hole and lineup the arrows and dots. I have pics of the cams installed. | ||

Check static iginition timing. Check fuel maps, seems to be a bit rich making the pipes glow at idle. In that photo album you linked, are those pistons from this engine? If so you have a problem with the cylinders, probably out of round allowing the skirts to scrape. | ||

Looking at the name ,probably from a dirt bike! | ||
| 04mx |
those pistons were snowmobile pistons. I did put the static timing back to what it was. what do I do with the map? | ||

Maybe start with a stock map for your bike and then tune from there | ||
| 04mx |
where can I get a stock map for the bike ? I'm new to buell's so don't know much. | ||
| Reepicheep |
Was at least one rocker box off when you put the cams and cam cover back on? If not, I'm amazed you got them back together (and the fact that you did makes me worry something is wrong). | ||
| Elff |
The stock maps can be found on the ecmspy website. I'd have to double check the address as I am responding via my phone. | ||

Second video sounds just fine to me. | ||

The photobucket link is now down on my computer, but if the sparkplugs at the start are the ones from your bike, and the dark one is from the rear cyl, perhaps an injector is fouled/leaking. Easy enough to check. Remove the air box cover and the air filter cover. Turn ign switch on, do not start engine. Turn stop/run switch on for 2 sec, then off for 2 sec. Repeat 5 times. Then open the throttle and look in the intake manifold with a strong light. If you see any sign of fuel, the injector is leaking. A leaking rear injector will give a rich mixture in the rear cyl, and can fool the 02 sensor into skewing the mixture across the fuel map. Hope this helps, Dave | ||

If its only doing it at idle then I nigh be the idle Air control valve. Hit that with some carb cleaner. | ||

yes I took the rocker boxes off to put the cams back in . I did test the injectors by using ecmspy and testing the fuel pump ,I removed the injectors, put them in a bucket turned the fuel pump on and put 12v to the injector and all seems to work fine. at first I thought it was bad (spraying) sideways but when I tested the front one it did the same thing but to the opposite side. | ||

Good to know the injectors are 'firing' as they should. One question answered. The test I suggested is based on my 2 experiences, both on X-1s. Injectors that were otherwise OK were causing running issues. One involved a friends bike; intermittent running on one cyl. After swapping seemingly everything but the gas cap, we swapped injectors front for rear and the problem followed. On my bike, one injector was 'drooling'; i.e. it still flowed fuel even though it was 'off'. The above test should show if you have a leaky injector, which could explain your running issues, and the extreme difference in mixture between front and rear cyls as shown by the plugs in the photo. Hope this helps, Dave | ||
| Greg_e |
Did you get the injectors back in the correct spots? Having them squirt backwards can cause some issues. Have you checked for air leaks around the throttle body mount flanges? | ||
| 04mx |
injectors are not leaking during test above. I did not remove injectors from the rail ,just removed the whole kit from the throttle body and started the fuel pump with ecmspy and put 12v to the injectors using a small 12v battery. wondering if the fuel map might be off somehow making the plugs front to rear so different? | ||
| 04mx |
 plugs have idle time only. | ||
| Firemanjim |
Did injector wires go back on correct injector? | ||
| 04mx |
yes they should because the rear one had a small righting saying rear on the plug and also when I tested the injectors I did them I at a time. | ||

Was this bike ever running when you owned it. You don't really provide much history prior to "I just got it running". Backfiring through the intake sounds like an intake valve that is open during the power stroke. There could be any number of explanations for that, including the possibility of the cam timing being off. Do you have compression in both cylinders? | ||
| 04mx |
I never rode the bike, I bought it this winter and only heard it idling. I dropped the motor again just to make sure the cams were right and they seem to be fine ,I took a pic with my cell ill post it soon. compression front is 120 and rear is 125-130 psi on the gauge I use. I'll take it out for a test ride tomorrow. just wondering what's up with the plugs front to rear,COLOR AND GROUND STRAP with only idle time. | ||

 cam timing | ||
| Greg_e |
Is the E stamped in the cam for the lobe shape, or does it mean E for exhaust? I don't remember what mine had stamped on them when I did the oil pump drive gear a couple years ago. (Message edited by greg_e on May 30, 2015) | ||
| 04mx |
1E front exhaust 2E front intake 3E rear intake 4E rear exhaust . | ||
| Greg_e |
Then it looks right to me. Static ignition timing is really the only other thing unless someone has really messed with the fuel/ignition maps. | ||
| Elff |
If you PM me your email address, I can email you the stock maps. | ||
| 04mx |
that would be great.I'll pm you my email thanks. how do I put the new map in ? can someone walk me through it? thanks for the help  | ||
| Greg_e |
One last thought is that maybe the crank sensor is going bad, they are too much money to just replace, and you really need an oscilloscope to check it. There is a thread or two on the subject so it would be worth a search. But get the fuel and ignition maps back to stock so you have a known good condition to start from. |
