Yep. All the follower pieces were contained to the head. I have all the pieces I need. At least I think so. Not sure why there coolant seems rusty. But then again I have no idea what the previous owner did or did not do. | ||

Trying to put this baby back together. A few questions since its been a while since I took it apart. Where does the map sensor mount? How is the clutch cable routed? Does it go through the loom with the wiring harnesses to protect it from the header? | ||

Shawns, PO might have drained the coolant out to do trackday(s). Mineral water  I've taken some pictures of the clutch cable routing. Please wait... | ||

Some duplication...sorry. So, when the clutch hose leaves the reservoir, it goes through the p-clap on the lower fork clamp, then over to the O2 sensor (and this is where it gets a little fuzzy), then behind the right fan bracket, then down along the same path as the wiring on the right side. I hope this is helpful...steve | ||
| Shawns |
Yes that does help. Thanks. Is yours an 08? My 02 sensor is in a different location.  | ||
| Panshovevo |
Steve's pics show the location of my '08's O2 sensor, and your pic shows the location of my '09's. Brief highjack...(sorry Shawn) Anyone know if the '09 location makes any noticeable difference in the performance or life of the O2 sensor? | ||
| Two_seasons |
Yes, mine is May 2008. I'd route to the inside of the O2. From what I've read in this thread, I'm pretty impressed with your wrenching skills Shawn  | ||
| Shawns |
I can take anything apart. Putting it back together that's another thing..lol. its getting there. I believe I have the hoses routed properly. Going to try and finish this week. Baby steps.   | ||

Look at all that pretty plumbing  FSM doesn't have pics like this to show where all that metal, rubber, plastic goes  But the upside is we have BadWeb  Would you mind putting up more pics as you go along. It would help us amateurs fumble our way through the maze. | ||
| Shawns |
Well it runs. Backfiring out of the front cylinder. Something else to figure out. At least it's the end of the season. | ||
| Two_seasons |
According to page 3-10 of the FSM... Engine runs irregularly at idle o valve clearance below spec o intake air leak o malfunctioning ignition unit or incorrect ignition timing o valve and/or valve guides worn or imperfect valve set Engine runs irregularly at higher speed o fuel pressure too low o intake air leak o worn camshafts Insufficient engine performance o intake air leak o incorrect or worn spark plugs o improper valve clearance o incorrect valve timing o insufficient ignition voltage o inoperative or damaged crankshaft position sensor or ECM o valve and/or valve guides worn or imperfect valve seat etc... HTH | ||

I'm hoping it's an intake leak. It didn't do it before I worked on the rear head. I checked the valves and they were within specs. | ||
| Panshovevo |
Shawn, just for clarification, when you say backfiring, is it 'sneezing' out the intake, or popping out the exhaust? In piston powered aviation training, we were taught that if it fires or pops out of the carb, to call it backfiring, if out the exhaust, call it after-firing. | ||
| Shawns |
It is doing both. I can see combustion through the front throttle body when closed. It also puffs air out of the iac hose. It didn't do this before. I used both the cam locking and crank locking tools when i serviced it. I don't think it is a timing issue. If I rev it up to a higher rpm it doesn't seem that bad. If it was timing I would gather it would be through all the rpm ranges | ||
| Panshovevo |
Is there any possibility the coils are wired backwards? To clarify, any chance the wires are reversed, front to rear cylinder and rear to front? (Message edited by Panshovevo on November 08, 2015) | ||
| Panshovevo |
I'm not yet sufficiently familiar with the motor...did you have to do anything that affected the timing of the front cylinder? I don't know how many degrees one tooth off would make it, but a cylinder with the cam timing retarded a little might run better at higher rpms, IIRC. | ||
| Shawns |
Nope. The harness wouldn't sit properly. The front coil wire had a cracked locking tab. I made sure it was seated and no change | ||
| Shawns |
I did the valve service in the front head and that was it. The rear was the one I originally had the issue with. It had 2 broken followers. | ||
| Panshovevo |
Let's say just for the sake of argument that the rear cam timing had slipped, and caused the broken fingers. Could you have timed the motor so that the rear cylinder was now correct, but the front was off? If this is a dumb theory, forgive my ignorance, just brainstorming with a shitload of painkillers in me. (Back is still f#*ked up) | ||
| Shawns |
I would hope not. That is the purpose of the cam locking tool. It holds the cam in place while you do the service. There are timing marks on the gears to line up. | ||
| Shawns |
So not an intake leak, swapped injectors and no change. With throttle bodies open I can see the intake valves. They are open at the same time for both cylinders. | ||
| Stevel |
Broken followers are normally caused by valve float often resulting in a displaced shim. This in turn causes an argument between the valves and the piston on who will occupy the same space. I am inclined to think you have bent valves. I would locate and borrow a leak down tester and make certain you have good valve sealing. | ||
| Alex |
"They are open at the same time for both cylinders." Depends on what You exactly mean but maybe You have built a big bang engine by accident. Mechanically possible but the ECU won´t do. You better check that the valve timing front to rear is correct. If the rear intake valves open and within a quarter of a crank revolution the front intakes do the same You have a problem. | ||
| Shawns |
I was referring to both intake valves moving at the same time in one cylinder at a time. | ||
| Dennis_c |
could you have a broken wire | ||
| Shawns |
Anything is possible. The front cylinder is firing so If I did, I don't know what wire would make it misfire. I am going to swap out the plug and the coil next and see if it helps anything. Bike bit me when a wrench slipped. Right to the bone. Not bad, only five stitches. As soon as I get them out the adventure continues.   | ||
