Short question: Is there any functional benefit to the late 2000 - 2002 placement of the HTS in the center of the head as opposed to the 98 - early 2000 HTS location next to the spark plug. Long version: I'm rebuilding a 2002 X1 that dropped a front exhaust valve. The 2002 rear head didn't suffer any damage so it could be used in reassembly. To replace the front 2002 head, I purchased '99 M2 heads and failed to consider the different location of the head temperature sensor. Will the two different HTS locations provide different temperature readings? If so, I'm assuming that the 2002 ECM is designed to read the "normal" temp reading from the location in the 2002 head. The '99 M2 heads are in pristine condition. They were used for 2000 miles then the ports and chambers were glass beaded, valves re-faced and lapped in, and new seals installed. The 2002 rear head would need the same treatment so I'm just wondering if it's cost effective to use it instead of the '99 M2 head. | ||

Good question. I'm just guessing here that though there might be some difference in temperature and the rate of warm-up it wouldn't be enough to significantly affect the calibration. That's assuming the same sensor fits in either location. Both sensor locations probably give close to the same temperature once the engine is fully warmed up such that they're both in the "normal" range for the fuel calibration. I wouldn't be afraid to try it on my own bike. Kurt |
