Team Honda SXS Looking for some help …… Story time
Trying to help out my Brother in-law with his 2015 Honda Pioneer 700 4 seater.
He is having 2 separate issues, it is eating starting motors and its running like crap.
The bike got 5 years out of the OEM starter until the two long bolts backed out causing the spline on the armature to wear off. Replace with an amazon aftermarket starter that lasted 6 months and the spline worn off again. Replaced with a different aftermarket starter bought at honda dealer along with OEM Honda toque limiter sprag bearing.
Enter issue #2 while driving around the idle changed and the bike shut off, restarted and would not stay running so extended throttle cable adjustment causing it to rev high had to shut off to change gears Returned throttle cable to original position, went on a ride and the bike fouled a plug, blamed it on old gas, drained gas replaced with new, now blowing allot of black smoke. Tested compression 60 psi, manual says 80psi on turn over. Took top end apart, piston and cylinder looks good, honed to put cross hatch back on cylinder, replaced rings and gaskets lapped valves. The exhaust valve was heavily carboned up and pitted adjusted as per spec. Inspected cam and questioned auto decompressor workings, it seams to be solid when pushed down but move it slightly and it compressed, I know this works on centrical force….. but it might be correct. Assembled new ngk spark plugs tested coil, still 60 psi. forgot to top up coolant in machine, started and it got hot causing the magnets in the starter to explode killing starter (starter #4). Leak down test holds 25psi, used 3 different compression testers all said 60psi Took top end apart again and inspected for damage did not find any. The timing line on the top cam gear does not go horizontal perfectly with case its like its ½ a tooth out so we put it in the direction of the engine rotation.
We figured out the starting motor issue, it is only held down by two bolts on the back and goes in a hole in the front. The hole in the case is worn or the starting motor housing male end is machined smaller allowing that end of the motor to move around killing the spline. Heat also plays a big part in the health of the motor as we tried to make one out of all the parts and used a torch to try and melt the glue that holds the magnet to the steel housing. Steel housing expanded and magnet exploded. Question is how to fix this movement? Install thicker O ring, apply jb weld to case, install brass shim, devise a way to secure front of motor.
The bike is still running like crap took out the IACV idle air control valve it was rotten cleaned, took sending unit out of tank filter is dark but thank was clean, ordering a new filter today, blew out fuel line, took throttle position sensor off and inspected, took injector out and sprayed into bottle, cleaned sensor in airbox. Brother in-law says the bike flashed code 23 or 24 for the O2 he replaced with a OEM Honda one still has code. He also said it blinks code 9
