Check the plugs for fouling. The ECM knows when the engine isnt firing right under a load.

Friend was having light come on under acceleration.  Went to check spark plugs and found that the screw-on tip on one of the plugs was very loose.  Tightened it up, re-installed plug wire and problem solved.  It should always be so simple, lol.

If you're interested here are some threads on some bolt in cams (Freedom/Yuill Brothers and Zippers Cams) for the 103ci motors...

REDSHIFT 575 CAMS & OTHER PRETTY PARTS (several dyno runs in this thread)

Hey Naitram-  I have been told by two mechanics (one HD and one indy) that you don't have to pull the cam plate to inspect the inner tensioner.  They use a dental mirror to visualize  that part.  I had my bike at the local HD shop and ask them to inspect these parts.  ( My SERG has 25,000 on the odo)  After seeing a one hour charge for labor, I ask them how they got to the inner tensioner.  This is the explanation I got.  Is the HD mech blowing smoke...? He told me both were "fine"  If so, I need to take the bike back and have them remove the cam plate!

ok, i'm not saying it cant be done that way but can they really do a thourogh inspection?

,ayne one of our resident wrenches can speak up on this one

What I have done is to use a pin punch, 1/8" I believe, and hook the ear of the inner tensioner and lift it up using the top edge of the cam plate as a fulcrum. You can then slide in a locking pin to hold it up unloading the chain. Once it's up in the air like that, inspection is easy with a small mirror.

This method also allows removal of the cam plate without stressing the bearings when the cams come out of the inner cam bearings and the chain is still under tension.

I can check the obvious and thanks for the tips, but yesterday on the way home from work the bike started backfiring and the light was coming on just going around a corner. Made it home OK but it seems like it's getting worse. I'll also ask the mechanic about Chiefs method of checking the tensioners.

How long until you can get the diags run?

[FUZZNUTS]

Probably next week. Tues or Wed.

Sorry to read of this Fuzz.  Was concerned that it might be something more problematic so it's good the idea was on your mind and you've already got shop time ahead for it.  Good luck getting it sorted and that it proves to be minor rather than major.

I'll post the results of the mechanics diagnosis. It just sucks that the bike will be down for the weekend. Just as well ,I have to split wood this weekend anyway.

Spiderman your a genius, did the ignition thing six times. No engine lights at the previous conditions stated. Running good.

Fuzz, if you did clear some codes or somehow manage to get away from some other electronic reporting that's great.  Unfortunately the multiple cycles of the ignition switch wouldn't have any impact the bad running problem you described later in the thread.

Has that repeated itself?  Maybe just a one-off bad moment?  Or you thing there's still something else going on there?

I put about 170 miles on the bike yesterday, no repeated problems, no backfiring at low speed. However, the engine light dose re-illuminate after the initial start up. It dose go out after a few seconds. Which means the ECM is holding that memory of what went wrong. I think. I'm still going to the speed shop Wed to get my baffles changed, ( I think I'm really pissing the nieghbors off) and oil changed. So the Diag's will still happen. I was looking at the ECM threads and (copout221) had a similar problem. Athough he's got a 07 and mine an 03.

I was told by an H-D Tech many years ago when H-D went to Delphi ignition that you can clear the codes on the ECM by doing what I suggested. I had some issues relative to the ECM in the time I owned  my two 03 SERKS and the switch cycle routine always worked.

Having said all that, of course as Twolanerider has pointed out, you can't fix a broken leg by drawing a picture of a cast on your skin. My post was simply in reference to Fuzzy's issue with the engine light being on.

Have been told the same thing BB.  That some certain number of on-off cycles clears historical codes.  Can't say I ever paid much attention to it though.  If I knew there was one for which the problem was either false or fixed always just knew that after riding for a few days the code would eventually clear and go away after I started and stopped enough times.  I like lazy solutions that actually work and don't hurt anything.
