I hav a 2006 Yamaha Bruin 250. It was given to me in pieces(engine) got the head back on and I have a few problems.

after installing the cam gear and chain I turn the engine over back to the timing mark and my mark on the gear is 180 out. 

So I reset the timing and thinking I needed to put the tensioner in and I can’t install it. 

And now some how the transmission is in gear and can’t get it back in neutral. 

 

Any ideas?

thanks in advance

Does this help?

 

Update. Got it back in neutral. Think I will pull the stator to reset the timing that way. Still curious about the tensioner tho.

 

yes after some research I found that. Thank you.

 

so now I have to get to the crank because I don’t understand why when I install the timing chain with cam and crank at tdc when I turn the engine over by hand back to the “T” I’m 180 out at that point

If you have the piston at TDC you should install the cam with the lobes facing down. That will put you at TDC on the compression stroke. Install the cam sprocket into the chain with the marks lining up to whatever they should line up with (different by brand), and bolt the sprocket onto the cam. Then spin it over counter-clockwise by hand and the marks should still line up. This is for all 4 strokes.

Yes I had the piston at tdc with the “T” in the hole with the plug removed. I spun the cam over so when the sprocket is installed the pin and the line on the gear is pointing to (12 O’ clock) towards the point on the head. Everything is at tdc.

      1999 Yamaha Big Bear 350 4x4 no spark

      Troubleshooting a no spark issue, was running OK, maybe a little rich, turned it off, now no spark. I've checked/ohmed out the main key switch, the start/stop switch, neutral switch, brake switch - all good. It will crank the starter, but no spark with the starter or when I try the pull start. I've checked all fuses and diodes. Swapped battery. New plug. New coil. Swapped in a used CDI - no help. Traced, removed, cleaned, reattached all grounds. Removed things like my winch from the circuits to be sure a bad relay or something was dragging it down. When testing voltages, the orange wire going from the CDI to the ignition coil shows no/very low voltage-shouldn't it have 12V on it? Sometimes I get a very weak, intermittent glow on my spark tester, but not enough to fire the plug. I've checked continuity on just about all wires in the harness. Checked/cleaned/lubed w dielectric grease- all connections, redid a few that looked old/dirty. I've checked the stator resistances, all good, but have a stator and rectifier ordered anyway, will arrive Sunday. I verified that the rectifier has a voltage output back to charge the battery while cranking - 10.5-11V, low, but expected while starter is engaged. What else can I check as part of troubleshooting? I have a Haines service manual, but the 1999 350 4x4 seems to be an odd model, there isn't an exact electrical diagram for it, but found one for another year that has all the same number of wires and same color wires, so I've referenced that. Any hints, tips or advice would be appreciated! Thanks!

      2001 Yamaha Bear Tracker Circuit Relay Issue
      By fwsamm
      Im aware that this relay needs a positive (+) and a negative (-) to activate the other side. The blue wire is the neutral wire so when in neutral it gets ground. The green wire is from the parking break; when you pull the break in it gets ground (-). however one of those two needs to be neutral so that the positive from kill switch can go to the starter relay. The ground from the starter relay is from the start switch. Which one (neutral or parking break) should have a positive (+) voltage?

      Need help! 1987 Yamaha Moto 4 350
      By P_syko
      I’m brand new to 4 wheelers and just bought a 1987 Yamaha Moto 4 350. It has good compression and fuel, but no spark. I’ve looked high and low trying to find how to test all the components of the ignition system, but can’t find anything. This has a new CDI box on it, but I suspect it might be the stator. How do I test the stator on this? Any help would be greatly appreciated!
