Was out riding today with the 05 XB9SX. Going along at about 70mph and the engine did a quick cut out. Might even call it a hiccup. It would do this right around 65-70 mph. Did it once leaving from a stop light. As I was getting home the bike just died just after starting forward from a stop. Getting close to home it did the minor cut out with some black smoke from the tail pipe. (Wife was riding the XB and I was behind her to see it this time.) Hooked the bike up to ECMSpy and checked for codes. There were none. Checked the TPS range of motion and it was smooth up to 100%. AFV is 105. Started the bike and ran it to let the engine get hot (fan on hot). Head temp worked correctly (single digit rise). Once the fan was on I cut the bike and test the TPS again. Same smooth rise to 100%. Not certain what is going on here. I want to say it's the TPS going bad at hot temps, but being it didn't show then I don't know. Anyone? | ||

D, curious. Are you saying that it could be the cam position sensor? I haven't noticed any tach issues, but certainly won't rule it out. Bike is due to maintenance, will do a freshing up on it tomorrow and test again. Will check the cam sensor if I can. | ||

I guess I should add, is there any way to test the cam position sensor without the o-scope? Should add. Bike has 60,000 miles on the clock. Also, D, now that I think about it. Your mentioning this sounds very much like when my dad's wide glide had it's CPS failing. It would cut out, sometimes just die, start up and run until it completely died.

Just saying, it's a relatively cheap fix for what it is and it doesn't show anything in tunerpro or ecmspy. I guess the only way to see it is with an O-scope. I just figured it was worth changing it out to see if it fixed it on mine. Obviously I had other issues as evidenced by the crack in it, so it was getting changed either way. So far, it's run 10x better and I didn't really set the timing properly, I just marked the old one and put the new one in the same place. Btw, this is what mine's making at the wheel now. Fueling is still off (rich) but it's better than it was before. Yes, it's a xb9. Yes, that's 70 ft/lbs of torque, motor is stock. I really need to check the timing and fuel to make sure it's right.

I checked on it on American Sport Bike. $150. Ouch. Any chance I could source it from a car equivalent? Or, where did you get yours? | ||
| D_adams |
Got a part number? Mine was only $80 local at Gateway-HD. Could have gotten it even cheaper online from surdyke.com though. This is what mine uses, yours may be the newer model. http://www.surdyke.com/AdvPartInfo.asp?PartNumber= 32400-94A (Message edited by d_adams on June 16, 2013) | ||

Yeah, yours is an 03. Don't think my 05 is the same part. Wish I had a part number for it. | ||

Price: $59.80 | ||
| D_adams |
Call any local dealer, have them look it up and get the number from them. See what their price is. If you can afford to wait a week for it, order it from surdyke. | ||
| Cataract2 |
Ow, just got the part number for the 04. $98 for a parts bin on and $120 new from surdyke. Sigh. Wish I knew if the 03 would work. | ||
| Cataract2 |
Hogs, where is the price from? | ||
| D_adams |
What's the part number for it just for future reference? You never know, it might help someone else down the line. | ||

Pretty sure 03 uses a different sensor because I'm almost certain the pickup wheel has different fins. | ||
| Cataract2 |
The part number for my 05 is 32443-04. Best price I've found is $98 parts bin one. Not comfortable on that one myself. Thanks Greg. You are probably right on that. Wonder how much the pickup wheel runs... Might downgrade it just to save some $. First thing I should do though is see if it is bad. Wonder if Autozone rents o-scopes... | ||

That's funny, the scope is cheaper than the part! Given the bike has 60k miles, replacing that crank position sensor isn't a bad idea even if it isn't toast already. I tried to think of ways to check it even though I have two scopes in the garage. I couldn't. Well, I could, but it would have involved building a special microcontroller diagnostic tool, which I could do for about $30 worth of parts and 40 hours of work, but why bother when you can buy that little DSO Nano scope (which is pretty much exactly that). Those screen shots I posted even show you exactly how to set up the scope (which can be a challenge if you haven't had time to understand what they all do). Sounds like you are near an army base... surely a six pack of a good local brew would get you a good tech with a good scope and as much time as you need. Use the wiring diagram to find the right wire going to the ECM, have a paperclip already bent and ready to go into that connector from the back, pop off the seat when the bike is running badly, hook up the scope, and fire it up. | ||

Don't know if I updated my profile. I'm now in Charleston, SC studying electrical engineering at The Cit. No worries about understanding the o-scope. (Heck, in the Army I used them for sat comm.) Just would need to get the wife's approval to buy it. Course, I can see a lot of use for one down the road... | ||

Looks like they just keep getting better and cheaper. I have the DSO nano V2, which works fine but has a pretty mickey mouse case and probe. Looking at this one: http://www.ebay.com/itm/ARM-DSO-Nano-Mini-Pocket-S ized-Handheld-2-8-Color-TFT-LCD-Digital-Oscillosco pe-/310675434428?pt=BI_Oscilloscopes&hash=item4855 b2ebbc It looks much better made, and is under $70 to your door (if you aren't in a hurry). Mine has an external signal generator, but I'd rather have the better probe setup and case. And of course the newest $180 4 channel setups with aluminum case look pretty sweet. I wish I had an infinite budget...  | ||

Good info overall. I think in the long run since a sensor is the same price as the o-scope. I might just get the sensor and replace the one in there. | ||
| Cataract2 |
Does anyone have the part number for the seal that goes behind the cam sensor? Mine is weeping a little bit and I figure getting to it now isn't a bad thing since I'm already in there. | ||
| Cataract2 |
Never mind on the cam oil seal. Found it. James Gasket 11124. |
