Recommended Posts

I do have an inline spark tester and will check that out this weekend as its currently pulled apart again i went ahead and prdered a fuel valve (old one had just started leaking right after i originally posted) and another fuel pump both will be here friday abd my buddy has a brand new caltric carb im going to put on it at the same time so hopefully i can rule the fuel system out all together. Im also cleaning my tank and the pickups in it at same time hopefully all works after. Ive tested the etc and its working right so im pretty sure its not the problem.

Sounds fuel related. Too much or too little fuel to keep it going. You would smell the gas if it was too much, my guess its too little. I would add a clear fuel filter before the carb to see if any debris may be getting to and clogging up the carb. Takes very little to cause a lot of headache...

      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.

      I generally use Non Ethynol fuel in all my small engines. I just got back from the gas station and that fuel has really increased in price since last year, I will continue to use it, even though its north of 1.00 a gallon more. That seems minor compared to cleaning and repairing carbs every year. 
      I was just curious as to what others are doing in regard to gas in their quads, i know a lot of the newer ones are fuel injected which shouldnt pose a problem, but i have had lots of problems with rust and jell forming in carbs when using ethynol fuel.

      having an issue with the unit when running under a load up a hill or in high gear, seems like the belt is slipping, there is a clapping sound coming from the primary clutch like it releases and snaps back in. i don't think I should have a noise like that. this is a friends unit and he has already replaced the primary twice with the same result.
      not sure where to look next

      Hi, I am having issues with my TRX350D fuel pump.  It suddenly stopped running so I have replaced all the fuses and cleaned all the terminals.  I have fitted a new pump, fuel cut-off relay and rectifier.  Still nothing!!  The pump runs when attached to a battery.  The engine will start on the choke and the filter fills with fuel but it will  not rev and dies when the choke is closed. I have power to the relay but nothing at the pump black/white wire when cranking the engine.  Any ideas where to go from here would be very much appreciated!!
