Multiple issues with Foreman 400
Howdy, did a quick search and couldnt really find much like my problems, so here goes:
99 foreman 400, has been backfiring a lot as of late, took the dump screw out of the spark arrestor and revved it up, blew a lot of junk out. Seemed to help.
Battery keeps draining, wont hold a charge for more than a day or two even while sitting and not running, battery is new and checks out good. Here of late when you start it (after charging) it runs rough as heck, almost like a timing issue, bogs down when you give it gas and dies. Had a buddy come by the other day and while it was doing this he hit the light switch to on and it idled perfectly and you could rev it up, did this for about 5 minutes and then it just died. Checked for spark, and sometimes we would get one and sometimes not, checked the coil and its good.
All fuses are good and carb is cleaned. Where do I go from here????
