Honda Fourtrax bring back from the grave

Recommended Posts



there were too marks on the sprocket that lined up with the head, no marks on the head.  I took the cam sprocket bolts off and got enough slack to adjust the chain and put everything back together, still ticks, but worse now.

got it back together and started it up and it ticks worse now than it did before, thinking I dont have the timing right

It may have been correctly timed in the first place.  Did you check the manual ? Maybe reset it to where it was. But check the manual about the alignment before yo do all this.  It’s important.

Ok so your timing is there. Get after it.  

Tensioner is there as well.

eh sorry- computer issues up there:wacko:  meant to say yes that looks like the head on my bike

so thats literally exactly how i checked timing- t mark on the flywheel and marks on the cam sprocket.  I'm thinking the tensioner is shot letting it jump time or the valves are incorrectly adjusted.  btw, I was wondering how you find certain info in the service manuals?  I find it hard to find the info I'm looking for and get lost lol

Have you been to the download section and successfully downloaded a manual before ?

Hey @JacobSlabach take a look at these two videos.  It will help you out getting familiar with that engine. The 300 and other small cc engines were pretty much built the same.

thanks@Frank Angerano!  My motor has the dual valves (4 valves altogether) as well, dont know if that makes any difference...

Same premise. Just to understand the head and cam removals and more important is the valve adjustment.  Did you buy a set of feeler gauges ?

Good. So you have to double check timing and then adjust valves.

Keeping an eye on this thread, I will love to see you get it all up and running again how it should be. I really like the Fourtraxx but couldn't afford one and ended up with a busted up Suzuki LT250 but shes well on the mend now. I have to replace the barrel next to stop her burning so much oil! maybe then I can make some money and invest in a Honda (preferably a 4x4 but not sure how much Id benefit from it as Ive never needed it with the work I do)

      Today I went riding and towards the end of the day my quad kept dieing while I was riding it. Just riding like normal and it would start to back fire and then die. Do I need to clean my carb or what?

      Hi All,
      Hoping someone will be able to help.
      I have a 2006 Kawasaki Prairie 700 with twin Keihin Carbs CKVR D32. The Rear Carb is leaking out the side during cranking. it is not the float bowl overflow. It is on the opposite side of the carb from the diaphragm. 
      I got this bike not running and someone had already messed with it. I took the carbs apart , cleaned and rebuilt. Everything went pretty easy.  It looks like it could be missing a small tube between the carbs but I have all of them listed in the service manual installed. See the pic for where it is leaking from...
      Any help would be much appreciated.. Thanks.

      I cannot get this drum off, I already have another drum and backplate on order because I've ruined this one trying to get it off. Completely rusted to splines. I cant fit any hub or wheel puller known to mankind onto these lug studs to try and pull it off, I'm really running out of ideas.
