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.
