    1990 Yamaha Big Bear - Rear Diff Top Up Fix

    Thanks oxidized_black I have never used either heli coil or jb weld but have taken the time to look at youtube for both product usage. Is there any added advice on the job for the 'Big Bear' broken thread that you can point me to. Some questions I have to start with: Do I need to strip out the casing to drill the hole to insert the coil Do I use the original Big Bear (top up oil) bolt head in the new coil Do I put the coil in before I start using and building up with the jb weld Hope you don't mind these questions.
  3. Rear axle top up threaded housing broke today; please see pic. Quad still usable until today but no value in it for costly replacement. Would welcome any thoughts on "how can I keep it running" can the housing be repaired ???

    Yamaha 1990 ?? Big Bear 350 4x4 carb refitting

    Thanks guys I couldn't believe my own (strip down) notes. Regards Richard
  6. Hi again I am reassembling the bike after a few days when life got in my way. My notes show that the bottom carb tube is an overflow. But I am not sure that my notes are correct. I have 3 tube connections on the carb: top on is an air breather from the air inlet system. the middle tube is for the gas supply from the tank the bottom one I believei s an overflow tube. Is this correct. I attach a pic for clarity. Regards Richard
  7. SUCCESS I had to remove the shift pedal as recommended by Getch (thank you) to fully get at the lowest bolt. I hammered in the oversize torx but it didn't grab, just turned inside the dratted bolt. Had a coffee thought of swearing but instead used a centre punch and hammered the bolt head, eventually it turned and I took off the last bolt AND then had another coffee. But I didn't take any notice of how the filter came out, BTW it was very clean. I have a new OEM filter and like the original it has a closed end and the other end is open. I believe the filter should be replaced by placing the open end into the engine, so when it is fitted I see the closed end; is this correct.
  8. Thanks every-one. 2 minutes available today. I easily undone top right hand bolt using over sized tork "fitted" with a big hammer and it turned off easily. Didn't have time to get at the difficult bottom bolt so that is for Friday with a bit of luck. Thanks again for all your interest and excellent advice. This forum is an excellent source of helpful information from friendly & supportive members. Thank you again.
  9. Thanks guys Will try all your tricks, starting with the torx bit, if I have one big enough.
  10. Hi This bike is fighting me at every turn. 2 of the 3 allen key bolts holding the oil filter cover are stuck. They have an internal 6mm key which has been rounded out. Partly by me but mainly before I touched it. Has any one any experience in removing these stubborn bolts, that is the lowest (the most difficult to get at) and right hand top bolt. My thoughts are drilling the heads out or using a centre punch to hammer the heads around, (could this crack the engine housing where the bolt threads are??) also drilling and using screw extractor. Any thoughts and advice would be welcome.
  11. Thanks O_B It certainly looks like it should connect to something. I thought maybe I had made a mistake and taken something off and then lost it. Thanks again
  12. I have sent a picture which may explain better than my description.
  13. Hi. The air cleaner case has 2 ducts coming from or into it one goes to the carb. The other duct on mine is not connected to anything other than where it comes out of the case. It has an open end about 1 1/2" dia ending under the gas tank with a crankcase breather connected to it. Where should it connect to ??? (cannot see it in the service or owners manual) nor can I see any suitable connection point.

    1990 Yamaha Big Bear 350 - Throttle Cables

    Just for update These pics of my carb may help someone else. It is a single throttle cable that operates all that is needed BUT it has been fitted with a twin cable from the throttle assembly with one cable not connected. The pics show the operating connection with some red tape on it. Thanks again for help and advice. "still trying to find my VIN looked everywhere (I think)"
