Idle at altitude


Recommended Posts

For small changes in altitude, carburetors will compensate without any modifications. For larger altitude changes, carburetor jetting adjustments may be needed. A rough estimate is one to two jet size reduction for every 1,000-foot elevation increase. 

 

This may not apply to you if you are going back and forth in altitude, if you have running problems in high altitude i would just adjust mixture to get more air there is less oxygen in higher elevation. Just remember how much adjustment you made so you can set it back.

      Hello I have a 1999 Honda 300 4w/drive and I just replaced the Oem carburetor with a aftermarket carburetor after installing the carb on the bike it started great and idled like new one but when I shifted into first gear and tried to move forward it died, I shifted back In neutral and the wheeler started easy again I let it set there to see if maybe it needed to warm up but when I shifted into first and tried accelerating it died again, I am not a use to working on it and would appreciate any advise thanks

      I know I know, There are seemingly 10000000 posts about the fuel issues on the late 90's Suzuki LTF 250 Quad runners. But I just got my 1998 and I only got it for $200. It idles but nothing on throttle. I cleaned the carb, and ultimately I had to order a carb, fuel pump and petcock as cleaning everything didnt help. Any suggestions?

      Heres my story. Kinda long. I guess I was a late bloomer when it comes to quads. I had never ridden a quad in my life. Rode Dirt Bikes as a kid growing up. Back in Oct of '06 I found a Mustang on craigslist. Took it for a test drive one morning before work. Fast car. 351 Cleveland. I had planned on meeting the guy again after work. For some strange reason thats still to this day beyond me, I stopped in Hillsboro MotoSports on the way home from work. I had 6 Grand on me. There was a left over '05 sitting by the front door. It was on sale for $4999. It was $5499 OTD. I didnt even look at anything else. I knew nothing about quads accept I thought it really looked coool and I had the money in my pocket to buy it. I was sitting on it when the salesman walked up and asked... "Can I help you?" Without hestitation I pulled 60 Ben Franklins outta my front pocket and said "I want this Quad. Load it up in my truck." It was just about dark by the time I drove away from the shop. BTW, I didnt bother to ask my ol lady if I could buy it. LOL. Anyway, I took it by the house and showed her. She was kinda stunned but not mad. We drove over to a friend of mines house and unloaded it. I took it to the field across the street from his house. HOLY CHIT!!!!! I was surprised by the power. I had it for about 2 weeks and took it to Sand Lake. I was there a few hours and rolled it on a banked turn at the top of the bowl right before you get to the one-ways. When it rolled, I flew off and landed on my belly. The quad came bouncing and landed on my back. For a month I couldnt even walk. I was scared of it. I considered trading it for a 250EX. Went back to the shop. The salesman said..."Dude!!! You dont want a 250EX!!! Trust me. Just get used to it" I still wasnt convinced. I put it on craigslist for $4000. Calls were coming in. I had a guy that wanted to come look at it that evening. I decided to take it for one last ride at Browns Camp before I sold it. I was still afraid of it. After about 5 minutes I started feeling comfortable on it again. I decided right then, I loved my Honda 450 and would learn how to ride it instead of selling it. That was late Nov of '06. Work was slow for a Painter in Oregon. My new job everyday? Going to Browns Camp and ridding my Quad. I bought my Girl Friend an '02 Blaster. I rode my 450 for 4-6 hours almost every single day for 3 months. And yes, I know my way around Browns Camp pretty well. LOL. In March I bought her an '06 TRX250EX (Thank God I didnt trade my 450 for one of those) LOL Since then, I have become totally addicted to quads. I love them. Couldnt imagine not owning at least one quad. Luckily I have two. My "07 was $6500 OTD in July of '07. Bought it for my Girlfriend. Traded in her 250 EX. A month later we broke up. So, I wound up with two Honda 450's.

      Hi all, 
      Just looking for a second opinion before I start ordering parts.  It looks like from the below tests it must be a failing stator. 
      Background - quad runs fine but when I use winch it will drain battery, I can then pull start but even after running for 20 mins if I turn it off, battery still dead and does not seem to get charged at all.  Voltage at battery after charging using trickle charger is 12.5.  Start up and voltage shows 13.1 at idle, if I rev it up voltage drops to 12.5.  LED lights also flicker at night even with fully charged battery.   Really more annoying than anything and if it is stator I prob will not change until it becomes more of an issue or maybe during next oil change.
      Thanks for looking, appreciate any replies!
       
      Stator plug and letters show how I tested.
      [ ]  A  [ ]
      B      C
         [ ]
       
      Checked resistance on stator (manual says .1 to .7) 
      A = .7
      B = OL
      C= OL
      Voltage   idle and 3/4 throttle
      A = 31/55
      B = 15/33
      C = 15/32
