Hello, I've searched everywhere for more help on this issue.
I have a 2015 trx420fa5. I am having trouble getting it to start. A week ago, me and some buddies were riding at the river, I was in water that didn't even come up to the muffler hole. I pulled out to the sand bar where it shut off and never crunk again. I notice a few days before this ride, my bike was harder than normal to crank. It would fire up and die down unless I gave it gas for a second or two and then it would be fine. About 4 months ago, I had a professional install a gear reduction and a clutch kit and adjust my valves. Upon picking my four wheeler up he informed me that my valves were off a little and he got them adjusted and I should notice it crank easier. This was the case until recently. On other forums I've read people saying that the valves could be the culprit, on other forums, the compression. This might be the case for other peoples problems but there scenario just was exactly the same as mine. I don't see how the valves could be off again after such a short period since they were adjusted. Another repair guy told me that he could do a compression test be he thinks it'll be a waste of time since it has never had the piston removed and it doesn't have a pile of hours on it . This guy thinks it something electrical. I can get it to start with starter fluid but it only runs for a second. I would say it starts long enough to burn through the starter fluid. It's got less than 100 hours and about 500 miles on it.
I have checked the following:
1) Sparkplug is firing (I bought a new one even though nothing was wrong with the old one.)
2) Fuel (again nothing was wrong with what was in it, but I purchased some 101 octane fuel.)
3) Fuel pump is fine as I took the fuel hose off to watch it shoot my $13/gallon gas onto the ground.
4) Injector (Again, I've watched it spraying)
5) Intake valve is opening and closing.
6) All the fuses in the fuse box are fine, including the diode.
All comments are very appreciated!
