2001 Yamaha Raptor 660 Cutting out problems

Recommended Posts

Hi Guys my ATV keeps cutting out on me during races this is normaly when im on a straight and have it wide open and when I slow down to take the turn or jump it cuts on me so i have to pull in clutch and release to kind of kickstart the bike again which in turn makes me lose time. any ideas why its doing this? :huh:

does it pop-pop-pop as you are off the throttle? if so, too rich. Otherwise, prob too lean, or bring the idle speed up. it is fairly high on a 660, about 1100-1200 rpms. Clean the airfilter too OK?

let us know how it goes

Agreed, my LT-R does the same things when I have it set to rich or when the air filter is dirty. Probably a jetting problem or obstructed airflow.

      Got a 99 or 2000 bayou 220. Its started making alot of noise, then the starter would spin freely. Took it apart and determined the three bolts in the starter clutch had sheared. Installed the new starter clutch and in the process, not realizing that Japanese motors turn counterclockwise, I turned the crankshaft clockwise about a half revolution so that the key holes would be on top of the crankshaft for easier installation of starter clutch. I get everything back together and try it. The pressure is so great that its very hard to pull with the pull start, the electric starter turns it over but it struggles greatly. A key issue could be this. When I engage the choke the starter will barely turn it over and you can't pull start at all because there's so much pressure. Like the back pressure cant be released once the carburetor is choked. I'm pretty sure by turning the crankshaft clockwise I screwed something up but I cannot figure out what it is. If there's anyone that can give some advice it will be greatly appreciated.

      Talk about what kind of atv you have and what you do with it.

      Not sure how many of you will remember this or give a crap about it but back in 2016 I picked up my first old atv to rebuild. Yamaha bear tracker 250. I picked it up in NJ while I was out looking for a quad for my little guy since he started this atv thing after seeing a few old pictures of me in my hay day riding. 
       
      The person I was getting the 50cc quad had this one laying around and asked if I was interested in it.  It was beat up and hadn’t ran in a few years.  No spark the guy said and he left it to sit.  I wound up taking both bikes. 
      I wish I had pics but I deleted the original post on Quadcrazy and lost the old ones on my phone when I upgraded. 
      This was the atv that caused me to stumble upon Quadcrazy since I needed a little help with the spark issue.  So needless to say I fixed it, did some cosmetic work and she was good to go. I took it upstate and used the shit out of it for just about everything under the sun. This atv made it through some deep snow, mud etc. I decided to leave it up there and use it as a back up since it’s been about 50 atv’s later and I have newer machines now. But unfortunately it sat for some time and it’s a little beat up so I brought it back home and going to clean it up. Amazing how one year sitting has done so much damage. 
      This was the first atv that I owned in over 30 years! It’s the atv that brought me here to Quadcrazy where now I endlessly check the site to see what’s going on, who’s talking about what and who can we help with there problem or can help me with mine as well as the on slot of what I do today as a hobby with atv’s. It’s been a great pass time for me and my son with the projects we have gotten and get into. He’s learned how to ride so well it scares me a little watching him. He’s learned how to fix, maintain and upgrade atv’s. He’s insanely good with carburetors as well. 
      It’s a good thing when a kid wants to play in the garage over his X Box!!
      The funny thing about this bike is that when we finished it we thought it was the best thing! We were missing a rack on the front and didn’t care since it looked ok, had no clue where to get parts or how to fix plastics. I was so new to this again since I was staring all over again and now had to remember things and also teach my son!  
      So we will be tearing into the bear tracker to get her up and running again as well as maybe a few new cosmetic changes and hang on to her for a while since I love this bike.  The last two pics are the bike the day we finished putting it all back together and when it was upstate for the first week. 
       
      Had no intention of this post going so long. 🤷🏻‍♂️

      If we had a dollar for every time the question “Which is really faster, the 700 or the 450?” shows up in our inbox, mailbox, or voicemail, we’d be putting this magazine together from a bungalow on a barely inhabited tropical isle named Quadhama.
