Some of you know that I'm looking at replacing my dad's dirt bike with a atv. We found a really nice 07 raptor 350 for a good price on ebay. What are some cheap mods/adjustments that can help get more power out of a 350? Thanks

Porting, high comp piston, cam upgrade, bigger carb, exhuast header, and ignition upgrades. Unfortunately none of these are really cheap, but they are the only way you can get any real power out of that motor. Those bikes are quite underpowered, unless you have already gotten it, I would look for a 400EX, you should be able to find them in the same price range as the Raptor 350, and it is a much better performing machine.

My dad likes the 350 for its low center of gravity and its width. width is really important because we need to get it and my bike on our 5x8 trailer. If we don't like it, then we'll sell it this spring and get a 400. Here's the link. 2007 Yamaha 350 Raptor ATV Quad Extras Low Hours CLEAN :eBay Motors (item 130318380561 end time Jul-19-09 18:35:15 PDT) the seller has lots of experience with atv's and just got a brand new kfx450, that's why hes selling this one. He'll sell it to us for $2400 including barely used extra tires and all the other parts for the quad. Since this is our first quad, we really don't need to have it screamin fast. This will be our little "starter quad" i guess.

      I recently purchased a raptor 80 for my grandson for  christmas. I am trying to make sure it is running properly. i have rebuilt the carb and adjusted the carb idle then the mixture to middle of where it runs rough and it runs great for about a min or 2. then it stalls out. I can usually choke it and it will start so i feel it is lacking fuel. the fuel shutoff valve has been changed and i checked it for good fuel flow.  any ideas of what to check next. I am planning to vfy fuel float height tomorrow. I visually checked it by turning carb upside down when i had it apart and it looked level. any ideas are appreciated. 
       
      Thanks.

      I have a 1990 Honda fourtrax 300 2x4
      I rode the other day for 30-45 min. Switched it off and now it is completely dead..
      battery is fully charged, fuses are good . WILL NOT TURN OVER ,
      headlights won't turn on , No neutral, reverse or oil temp lights . Electrically it is completely dead !!! I replaced the key switch and CDI box , STILL NOTHING.
      I bypassed the neutral safety switch and grounded it to the battery and still nothing !! I used a jumper wire on the starter Solenoid , the motor will turn over but not start . I even bypassed both fuses and straight wired it to see if I could get a neutral light or headlights still nothing . What could it be ?

      I am trying to diagnose a no spark issue with my 02 Big Bear 400 and I am really hoping it is not a CDI.  I have done the test on the stator and I believe that is faulty.  I ordered a new aftermarket one from a the jungle website and it tested bad right out of the box so I am waiting for a different one to arrive from an ATV parts supplier.  I started looking out of curiosity at CDI units and it seems if it is for a big bear you are SOL.  Kodiaks, no problem.  Big Bear. No such luck.

      I got a 2005 350 Raptor Special Edition and I'm dealing with a no start issue; the weirdest thing is when I'm cranking it fires and slows down showing signs of pre firing, smoke shoots out the carburetor every time it sparks. every electrical part (CDI, Rectifier, Stator, Coil) has been swapped out from previous owner, the top end of the engines all new and I cleaned the carb out, anyone got any ideas or similar problems, also is it possible to have a bad spark timing

      I have had my new tires for a while, chronic procrastinator, decided it was time to get them mounted up. Against my better judgement i decided to mount them myself.
       

      I got one of these Harbour Freight manual tire mounting machines, mounted it to a half pallet to make it more portable. Very impressed with the quality and amount of tools that came in the kit for a low price point.
       

      The bead breaker worked very well, i wasnt sure it would be able to do it, i think these tires are original to the bike its a 2004, but with enough lube, mothers concentrated car wash straight, it finally broke the bead.
       

      Tire fit very well on the machine and it tightened down good.
       

      The extra long pry bar that came with the kit worked well to get the outer rim of tire off.
       

      Half way there, half way there no issues, then it got serious.
       

      I pulled and i tugged had 3 prybars working this thing and it wouldnt budge no matter what i tried it would not come off, until i got the grinder out and cut it off. Im sure most of you see what the problem was. I didnt notice it until i was too far in to change direction. On this particular rim the tire goes on and off from the back side of the rim, not the front like what i was used to. The back side is the low side. Plus to add to the problem tires were old and not very strechy, i have a greater respect for how well these ATV tires are made with well reinforced sidewalls, even with the grinder it took me a minute or two to cut through it, of couse i was being very careful not to nick the rim. Anyway the HF machine worked well and the tire is off, hopefully the next one wont be this bad. Lot of hard work for an old man, glad i can still do it.
       

      Now for the fun part , cleaning up the old rim, years of stop leak and slime caked on the inside, that stuff dries hard, the little Milwaukee is good for getting into tight spaces, but wasnt quite up to the task.
       

      Needed a few more RPMs.

      Old rattlecan paint just flaked right off. Now time to decide on a new color, tired of the boring gray. More to come!
