Hey guys! New to the forum... looking for some help! Im at the end of my skill set when it comes to troubleshooting my issue...
I have a 2007 Grizz 700FI with around 7000km on it. Its pretty much stock... other than a K&N air filter, a billet exhaust tip and an EPI clutch kit for 27" tires. No pipes or programmers or other upgrades.
I have had no issues with the engine or electrical system in its lifetime. Ive been good with maintenance and upkeep. So the other day I was out hunting... and the machine ran just fine as always. I had a long (15km) high speed ride back to home base. Didnt pin it the whole way home... but was cruising pretty good. probably 70-80km/h the whole way. So maybe 3/4 throttle? I dunno... not sure if it matters. Regardless, it ran fine...
The next day I went out for my evening hunt. Fired it up, let it warm up while i packed my gear, headed out on the road and within a few mins it started sputtering and running rough and eventually stalled right out, about a mile from home... I could start it, it would idle for a couple seconds and die. I tried a few times and eventually, it wouldnt even start. So I called my buddy to come pull me home... when I poured a drink and stewed about it for an hour or so. I another buddy showed up a couple hours later and I decided to show him what was up... To my surprise, it started fine after it cooled down. I went for a rip around the yard and when it warmed up, it started doing the same thing. Sputtering, bogging down, backfiring and then stall... Not able to restart until it cooled.
SO... after doing some research on this site and other sites, I did some basic checks.
I changed the spark plug (which was probably original and was pretty sooty black). I checked the wire connections. I cleaned the K&N filter. Added some Seafoam to the tank. And I checked the TPS diagnostics which came in at 16 (idle) and 100 (wide open). Which seems fine!
The problem persists!!! I dont know what to do next... Im going to do a compression test when I find a tester that fits. But I dunno if its actually a compression/ring thing as it fires right up and runs fine for about 5 mins. Its only once it warms up that it falls on its face... Something is heating up and expanding? An electrical module is heating up and failing? Fuel pump warming up and failing? I dunno.....
Any insight, experiences or suggestions are greatly needed and much appreciated! I need this rig for the remainder of the hunting season and REALLY dont want to take it too the stealership to get hosed... especially on a 10 yr old, miled out machine... Its really not worth the bill.
HELP!
