I have a 07 trx450er. When I punch the throttle, it falls on its's face. About put me over the bars!!!! Then it will take off after the puke. It doesn't die, it just doesnt respond. The bike is stock except I took out the spark arrester. I'm at a loss. Any help would be great.

well first of all when you took out the spark arrester did you adjust your jetting? if you didnt i would say you are too lean. if its cutting from idol to 1/4 throttle ist you slow jet. 1/4 to half it would be you needle. a buddy of mine pulled the arrester out of his 450er and we had to rejet. he also has had problems with valve adjustment.

      My 1992 TRX00 recently stopped firing.  I understand this is a common problem. I have ordered an aftermarket CDI unit.    TJ

      Hey all, new to the forum! I just bought a 1998 Kawasaki bayou 300, 4x4 not running. Initially I found no spark. Ended up playing with the plug wire (made sure plug top and wiring was touching) and got spark yesterday and the quad fired up off ether. Come to work on it today and now no spark again. Before I got spark and now today if I touch the plug after cranking I get shocked, and it will spark after I release the starter button. I was jumping the quad with a freshly charged car battery that has 12v while cranking. Cleaned out the kill switch and ignition button. All looks good. Purchased new plugs. They're are a lot of wires cut/ disconnected. But shouldn't matter if I got spark without them connected...

      Hi All.  I introduced myself some weeks ago with my 2006 LT-F400F that needed a list of repairs including replacing the cracked generator cover.  It is back together as of last night and cranks up, idles and revs high pretty well.  Needs some fine tuning and stop backfiring at stop.
      The big issue is it will not go into gear.  I reassembled the insides with help from y’all’s posts.  The transfer selector moves from H-L-R, and the foot shifter moves thru the gears and finds neutral easily enough.  Before I tear it back open, the  transfer selector on top does not move as far as the repair manual says.  The diagram shows the shaft moving something like 40 degrees between L and H and 50+ degrees between L and R but it doesn’t move that far even though it finds the indent areas and moves well.  
      Could this be the problem.  I aligned all the dots on the shifter gears inside and it appeared to not be binding anywhere.  I do hear the gears touching when I shift like they are trying to engage, but zero movement from the ARV
      It was somewhat difficult to tell whether all the parts are installed on each shaft.
      Are there better/bigger photos somewhere that would allow me to be confident I included all the washers and bushings, etc?  If I had any doubt on parts that were laying inside after the cover broke then I purchased replacements from online stores.
      TIA for any input or feedback!!  Pics are from when I first took the generator cover off.

      1989 Moto 4 YFM350ERW intermittent spark.
      Quad has set for about 7 years and was running when parked.  When I replaced the battery and attempted to start it had no spark. 
       
      What I have done.  Followed troubleshooting in the manual. 
      1.       Coil failed the resistance check so I replaced it.  Still no spark.
      2.       I performed resistance checks on the stator and they all pass.
      3.       Found a bad rear brake stop switch and unplugged it and connected the wires in order to disable.  Now I have intermittent spark.  I believe that the issue is with either the stator or CDI and not sure which.
      1989 seems to be a transition year for electrical.  I can get new aftermarket CDI units for 87-88 and 90-94.  I cannot get ones for a 89.  I can get new stators for 87-89 and 90-95.  Looking at the schematics the wiring on my moto is closer to the 90 ones on the ATV side of the CDI and closer to the 87-88 on the stator side of the CDI.  Looking at part supply sources the stator housing is the same part # for all the years and looking at some of the stators on Amazon that have the dimensions on them both of the stators are the same size.
      What I am thinking of doing is to replace the stator and CDI with a 90-95 one as these parts are all readily available.   Does anyone know if this has been tried before and if there are any issues with doing this.  
       As a side note I also have a 1993 Moto 4 YFM350ER that has been sitting longer but it is located about 400 miles from me at this time.  By doing this change in addition to being able to get parts I will also have 2 ATV’s that are the same electrically.
