I have a 2006 raptor 700. when I first got it it ran well with good power but I discovered that the decompression mechanism was missing. I also found the cam was scored and such so I replaced it with a used unit from eBay with the decomp in tact. While taking it apart i noticed the timing marks were off by 2 teeth or so but it ran well like that, but that is not the case with the new cam. It seems to have less power and uses a lot of gas. So what I am asking is why do you think it will not run with the timing marks lined up? I have attached a photo of what the timing marks look like on the cam.

I suggest you line up the timing marks the way it should be and try it out, timing marks are there for a reason, and maybe the previous owner had an ulterior motive with setting up this cam in the way it was set up.............

When I had the timing marks lined up it wouldn't start, would just crank over and backfire once in a while. Should I try lining the timing marks and re-adjusting the valves. Will that make a difference? Could the they just be adjusted to open to late like that?

Do you have the crank at TDC and the cam timing marks all on the proper timing marks...........

The crank is at TDC when I start, but the way the valves are adjusted now, wich is how they were when I got it it will only run when the cam mark is set where it is in the photo.

I just bought an 06 700 and it is having an issue starting. It cranks and then backfires. I might have to try your two tooth mod and see if I can get it to start up.
Go on try that tell us how it works for ya.

I would pull the flywheel to see if the woodruff key sheared or if the previous did not put it back in.

Worst idea ever.. this is not a mod :lol: There are two timing marks, and I and a H make sure you're on the correct mark..
