87 warrior wont rev up

Recommended Posts

i have an 87 warrior and it seems to run fine until i rev it up. when i ride and give it full throttle it seems as though it's hitting it's rev limiter, but it's only about half of whats normal. i cleaned the carb thinking that was the problem but nothing changed. could it be lack of back pressure? exuast could be pouched. or spark plug??? i don't know any suggestions?

Check all the simple things First....Spark Plug...Compression..AIR FILTER...CDI Maybe....

Is there a Fuel Pump on that????

No, but I do believe they have an accelerator pump, there should be a black plastic cover on the side of the carb, if you take that off, you can see a little off white, plastic mechanism that pushes down on a metal plunger shaft which has a rubber boot at the bottom of it. Make sure every thing looks to be moving ok and check to make sure the metal plunger isn't sticking. I would still check the simple stuff first like MWKE mentioned, then move to the carb.

Yeah I know, I had blaster on the brain. :laugh:

I know how that goes, if I only had a nickel for every time I had a brainfart.

      hey I'm dave westfall I'm new I just became an official member of this site a few minutes ago. Ive been crazy about quads and bikes since I was about 3 and ive always done my home work on them figuratively speaking. I would say for comparison to the common man that I am pretty knowledgeable about them. its been my passion about most of my life. I love talking about quads and bikes so if anyone out there would like to talk with me about mechanical subjects or about person experiences while riding or just shoot the breeze please feel free to chat with me. I'm looking forward to it.

      I recently bought a 2000 warrior that needed motor work. I got it all put back together and can't figure out why I have no electric coming on, it has a new battery with 12.5v the fuse is good and I believe I have all the ground wires connected. Any help or suggestions?
