How to change the ignition lock of Yamaha stratoliner 2007 ?

SOURCE: i need to remove the exhaust for a 2007 yamaha stratoliner.

i think you will find that the cables you are referring to as powervalve cables (if you are talking about the xv1900 in the picture)are not powervalve cales you will find that they are for the auto decompression valve in the cylinder head,if you follow them back you will find they terminate on a lever with a tensioner you can back off the tensioner to remove them but shouldnt have to just to remove the header,hope this helps

SOURCE: cross-threaded spark plug threads

On a newer motorcycle like this i would remove the head and replace. However, on less valuable engines, i would attempt to chase the threads with a tap made for this purpose. The risk involved is introducing metal filings into the finely machined cylinder bore. The best you can do is attempt to blow the filings out with compressed air. There are also thread inserts that can sometimes be fitted into the damaged spark plug hole. I recommend removing the head for this. This repair requires drilling out the hole and re-threading to accept the insert. Always start spark plugs by hand and turn several revolutions before using a wrench. Always allow the engine to cool completely before removing/installing spark plugs. Always torque spark plugs to specifications-do not overly tighten. Always replace spark plugs regularly to prevent siezing in the head- 3yrs max.

Some basic rules I've learned and all of 20 minutes out of you life. People complain about valve noises or sluggish throttle response, well a crisp set of plugs firing does a lot to resolve these issues and for only $10 (standard plugs) is the cheapest performance mod going.
1) Replace your plugs annually (or at a minumum follow schedule of rear tire replacement) regardless of amount miles.
2) Plain and simple. Don't waste money on iridium because of #1 they spark the same it's just the tips that are suppposed to last longer.
3) Full removal of the tank is not needed but you will need to move it out of the way. Remove seat, remove center speedo and disconnect connectors, remove tank bolts, disconnect vent tube at the front portion of tank, lay a towel across the frame where seat normally goes, lift tank and turn tank sideways it will rest there without removing gas lines underneath, stock air box removal is not needed (BAK is even better for access), not certain what they mean by rider's seat bracket (at the back of the seat?) but obviously this is not needed either. There are wires zip tied to the frame that might need to be pushed out of the way or carefully cut the zip ties and just add new ones when done. (This just allows better access to get to the spark plug on right rear cylinder.)
4) A long screwdriver with small hose on end helps retrieve and reinstall plug on the front cylinder (unless you have very long fingers)
5) Go to auto parts store and purchase a socket with universal swivel for proper angle to losen or tighten plugs
6) A small amount of anti-seize compound on the threads is never a bad thing unless you use too much or it smears across the tips which would probably burn off anyway but that's just sloppy mechanics. (You want to be a sloppy hack like that, well you're outta the club... Go ride another brand.)
7) Use your hand never the socket to start the threads on the new plug. Place new plug in hole near cylinder and spin in reverse to align the threads then go in normal direction. If it does not feel correct at the start - never force it.
8) Do not over torque the spark plugs when tightening.
9) When reconnecting coil wires make certain you press down enough for a positive click to ensure proper connection.
10) Put tank and seat back in place and prepare for the response "why did I wait so long..." on the first ride...
Hope that helps.

For riding 2 up I recommend 38 front and 42 rear. Some riders have commented on some front wobble corrected by putting the front to 40 psi.
