Little help please

Recommended Posts

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

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.

      I recently got a 98 warrior 350 that 'needed the carb adjusted' but the reality is it has no spark. I have a new spark plug, plug wire, ignition coil, battery, and cdi box. I checked continuity and took apart and inspected the starter/kill/light switch on the handle bar, and it all looks brand new and checked out. The key switch seems to be working properly, as when off, nothing works, but when switched on, lights and electric starter button work. It turns over fine, and as I just stated, all the lights work. I took all the plastics off and traced all the wires, and only one had a small cut in it, but it was only through the rubber sheathing, not the wire itself (the blue one coming from the stator). I cleaned some grounds, made sure both relays work, and still nothing. I pulled the stator cover and looked at the stator itself, and it looks great. No broken wires or connectors or anything. Still, no spark. I'm at a loss. Where do I go next? Any help is appreciated.

      Hi Everyone,
      I am new to this forum and hope that someone out there can help me, I have an early Suzuki King Quad 300 (280cc) which starts intstantly every time but at about half revs or there abouts it starts spluttering and will not rev any higher, this fault is present whether choke is applied or not, some one suggested that silencer maybe be clogged so removed baffle but no improvement have removed carb and stripped 3 times but still no joy.
      Any ideas would be most welcome.
      Cheers Rob

      I have a Yamaha 350 in at once to try to fire up but won't. It's getting gas fire air and it has a lot of compression but still struggles to start check the timing it's top dead center valves are good valves are adjusted everything's working but won't fire I put my hand over the carb suck in gas and it tries to but it makes a lot of black smoke. Also when I put my hand over do you carb and tried to start it there's black black nasty stuff in the gas. So I don't know if it's trying to burn too much or what it is the gas tank clean and it anything to do with the gas it's with it firing. Took the spark plug out and it's pure black. What is dried up black not nasty corroded wet looking. Need help to solve the issue
