Just finished with Zipper 575 install with the other goodies (thanks 103tHunDer for advice). On ride home about 40 miles later the bike lost power . on diagnostic was found to have cam shaft position sensor failure. Did anyone else encounter this problem? Is it something that during install needs to be changed or was just bad luck? PS WOW! on how it runs!!!!

otophile,

Did you mean CKP (crankshaft position) sensor?  I can't see where opening up the cam chest could have any affect on this, since it is located on the other side of the engine.  Looks like just bad luck, or maybe the wires got nicked changing the oil filter??

I too think it was just bad luck as Jerry stated, the sensor is on the opposite side of the cam cavity.  Happy you liked the way it ran after the cam change.

Yes, the Dephi injection system does not use a Cam position sensor, only Crank position sensor.  There is no rhyme or reason to their failures.  Some last the life of the bike, others I've replace with less than 200 miles on a bike.

thanks for input. Problem was had work done non Harley shop, when broke down had Road America which would only tow to HD dealer. Of course dealer blamed install and said not warranty covered item. I will recheck the work order , but I am sure you guys got it right and way it was explained to me was slanted to relieve any blame on MOCO. ( started with conversation about improper pushrod installation causing misfire or "burn out" of sensor? Unfortunately I am wrench ignorant so have to trust what people say, go figure!) John

PS thanks for correction on proper part ! changed thread title so as not to confuse issue

Not likely, The CSS is on the other side of the motor and monitors position of the crank only, It has nothing to do with cams, pushrods or valves.

Were there any other noises or vibrations that you heard prior tp the power loss?

Prior to install was a noise in left side, during install tech found loose compensator nut. Other than that there was a new low level noise from right I assumed was gear drive. Bike ran for little over 50 miles, then cut out like ran out of gas. Would not turn over on repeated tries ( had fuel line replaced with braided one, and thought at first maybe dirt or debris blocked line, but that obviously would have been too easy). The only other thing I noticed it did not run as smooth in acceleration as before everything put on but can't be more specific than that ( was actually on way to get dyno tuned when all this occurred!)

The ones I have seen that have failed had metal particles on it. That will cause failure. Did you ask the dealer to see the old part?

As mentioned in some of the previous posts. The install of the cams should not have caused this failure as thay are on the other side of the motor. Same with the push rods.

DAWG,
unfortunately i did not get a chance to see the sensor.In retrospect would have been nice to see and post pix here. I guess it makes me feel better about after market shop that did install ( zippers had dealt with them and done various non harley parts add on for several bikes in past without problem).  The dealer in Jacksonville, FL that I have dealt with for 11 years has built a larger central store, and all the techs and Service managers have moved to the larger location. So I guess now I may have to drive the extra 20 miles to new store, or use the shop in Brunswick, GA for service (HD that is!). Any way up and running now so usually the pissed off level gets better the more i get to ride, but for a while i guess i will be paranoid about every sound ( still trying to get used to gear drive noise!)

But tell us, what about the dyno run. I for sure am interested in your results.

As soon as I get my scanner working will post dyno run. Spent day doing "burn in" on new Brembo brakes!  didn't get them to smoke but could sure smell them

[mr_magoo]

I've had 3 replaced but they all tripped codes several times but never had one fail.  Do carry one in the saddle bag, it is the 1 part that the bike will not run without.

I was just reading the thread on dealer lack of desire to put other than SYN 3 in bikes, well  to continue my dealer saga went to dealer to get copy of dyno tune (  could not find in paperwork, but told everything came out great). Talk to dyno tech,and low and behold while I got charged for four hours on dyno, they actually did not do any tuning!! It just could not get any better, now when I ride I have no confidence that they actually found what was really wrong!! i guess it is time to find another dealer, or get someone who can help me do things myself ( and believe me that is scary thought!!)
