Hi I have a 2006 yamaha 350 bruin which has broken its timing chain the problem I have is that I cannot find the timing marks for the engine for tdc and 10degrees before tdc for the timingI have a manual for a 350 big bear but the marks must be different can anyone help thanks John

There should be a clear mark on the flywheel indicating TDC, it is usually marked by a "T". There should be marks on the cam sprocket somewhere that probably line up with an arrow mark on the head somewhere. This is just a guess on my part, I think the best thing to do is get a manual specific to your machine. If you are going to be working on it, you will likely need it in the future anyway. Hopefully someone who knows a bit more about these machines can chime in and offer more help, until then, good luck.

      I'm in the middle of repairing damage from the chain coming off of this from the previous owner. (I learned this is somewhat common on these for various reasons.)
      What are you guys using to either help keep the chain correct and on the sprocket or guarding your engine in the case that it comes off / breaks?
      Is there an upgraded guard that can bolt around the sprocket in replacement of the currently broken OEM alluminum?

      Howdy ya'll. I am working ona 2000 Yamaha Breeze 125. It was in rought shape when I received it and I am working through issues as they pop up. The quad had been sitting for years. I was able to get her running again, but I need your help with the following issue:
      I don't trust the transmission yet and I don't want to make problems any worse. So, I haven't pushed things hard at all. Low rpms, less than 5mph in reverse.

      Nuetral: Runs as expected
      Reverse: She seems to be driving fine at slow speeds. Going into reverse at idle is fine, coming out of reverse back into neutral won't work (the shifter is just stuck). As soon as I turn off the quad, I am able to shift around without any issue.
      Forward: It slips. It seems to only transfer power to the wheels on a smooth surface and going slightly downhill. When shifting into forward at idle, there is a clacking sounds during the transition. Shifting back to nuetral works just fine.

      Other Notable Symptoms: There was old oil in the vbelt and when I was tuning the carb, it starting blowing out of the CVT cooling vent at the front of the quad. Made quite a mess. There is positive crankcase pressure due to piston blowby, that I have not decided whether or not I am going to fix (customer budget dependant).  Since the oil was old, much darker than the new oil that is in the crankcase, I am thinking it seeped past a bad seal while it was sitting for years. The oil that was in it when I first got it had gas in it.

      Thoughts: I am thinking maybe there is an issue with the clutch. I worry about the old oil intermingling with the dry centrifugal clutch. I was thinking my next step would be to take the cover off of the clutch and inspect it.

      Let me know what you all think. Any advice and ideas is greatly appreciated. This is only the 3rd quad I have worked on and I have a lot to learn.
