Hey Hunter, thank you for the perspective. It helped me get my camshaft oriented. I had the camshaft sitting in the journals 180 degrees off initially too. Maybe you have a different cam sprocket, but there are no imaginary holes. The cam sprocket does have three dimples (punch marks) which should sit at West, North, and East respectively. The North dimple (punch mark) is covered up by the decompressor guide, when installing the sprocket bolts. The decompressor spring lever with its projections (pegs) also has a dimple (punch mark) that is supposed to sit north. It is all in that manual if followed correctly. You are pointing directly at it all 1:51

Thank you for the video!

My buddy spent thousands on his Raptor . Eventually I got it after numerous other shops and individuals. No matter what I did I COULD NOT get the timing to line up . After numerous attempts I knew something wasn’t right and ripped it back apart . CAM WAS BENT/TWISTED. Got a new one BAM 💥

Rumble Bee 🐝 660 !! Appreciate the advice 😂 I gotta go back and add the gasket maker top the valve cover 😂 slow leak.

If you use a piece of wire instead of that socket extension to hang the timing chain when you remove it from the camshaft, it won’t fall down and come off the crankshaft. Saves a lot of headache when putting things back together. Especially if you are removing more than just the valve cover.

You might have the cam 180 degrees off, any time the Cam timing is off is when the valve would hit the piston. Ensure that when you are putting the cam in that the crank is lined up with the slit, and that you have the correct "pin" and oil galleries facing upwards on the camshaft, otherwise the timing will be wrong

You said you put on new carbs was there something wrong with the old ones or did you just change them? Still having trouble with backfiring and carbs blowing off boots when cranking. Timing all looks good unless its off just a tooth but would that little bit make it do that? Just asking to see if there could be another issue ive overlooked.

@@roycesands5475 When my 4 wheeler timing was off that's what caused mine but my timing was off by 90 degrees. I wouldn't expect the 4 wheeler to lanch the carbs out with only one tooth off but I've learned that, that specific engine is very very picky. I bought the new carbs because the old ones would not stop flowing gas out of the overflow even with two different rebuilt kits having a new needle jet, so I went ahead and got new carbs on amazon for $45-ish and they have worked much better and have alleviated some headaches. Like I've told other people, did you ensure that you used the correct indents on the cam to set the timing? Because that's how I ended up being 90 degrees off.

Is the only way to check the valve is to take off the whole top end? And would a stuck valve cause backfire and the engine to roll over faster than normal ?

Hey there hunter’s mechanic, did u get my mesage earlier today regarding the atv. Same bike 2001 raptor , same niche kit. When I have spark plug in it , engine won’t turn over but twice , I get 120 pounds compression , and turns over a lot with spark plug out , why won’t it keep turning over after 2 times with spark plug in ??

I replied it to but I don't even see my comment, must not of had good signal when I did and it just didn't upload.... I believe you mentioned using an ATV battery to help jump start but have you used a vehicle battery? I keep a truck battery in the garage to jump mine in case I need it. Double check the ground to the case, it should run from the battery to the left side engine cover. My starter wouldn't turn over damn near at all when it was dirty and it also smoked 2 of my starters.... worst case scenario is that your Camshaft decompression pin man not be working. When you are starting the engine, the camshaft has a small pin on it that decreases the cylinder pressure and once it fully starts, that pin returns to its position for full compression. I know a lot of people that watch my videos have the same issue and I never knew about it when I made my videos. @danil1581 has a video on that decompression pin on how it works. If you find no solution with another battery or cabling, thats where id look next. Let me know how it goes!
