I’ve seen a few posts related to this with some basic suggestions but no, yes this solved it for me, answers. So, it cranks slowly, sometimes failing after a couple rev, only after riding minimum several miles. Naturally suspicious of battery and replaced it. No change. Winter happened. This year said ef it maybe bat was defective. Replaced again, no change. One day at the gas pump of course, tried several times and cooked the solenoid. No prob jumped it w pliers until new one came. No change. Been using trickle charger weekly just to make sure. No change. I can only imagine the starter is perhaps slightly out of round or something that would make it heat sensitive. If i buy a starter and nothing happens imma be super pissed 😂 Also.. 2014 20k new plugs this year along w air filter, tires (get the 240!) cobra programmer, custom exhaust. *coolant and oil (syn) full, radiator fins clean as can be, no leaks.
***almost forgot, starts right up when cold
thanks

I haven’t had this problem, however, if I did experience this my first check would be battery. If you don’t have the equipment to check it while pulling a load and all your doing is checking voltage that is pointless. Any reputable auto shop can do this free of charge. If battery checks out good, and you say slow cranking either the starter is bad or there is a huge draw somewhere (short). Possibly the rad fan since it only happens when hot? Unplug fan and see if problem persists. Even if the fuel pump or the programmer was bad, it should still crank normal but not start. This is my best guess. Could always unplug programmer to rule that out unless it did it before the programmer was installed.

Autocheck: motor warning light on or any fault code in the display?.

Before replacing anything is useful to professional check the charge circuit: from alternator to the regulator output to see if it really is charging the battery.


Good luck:)

Yep, plisken, I thought of that too.

KiNG, if you have a bike with Ivan's flash you will have a sticker on it and can simply remove the fuel tuner and see what happens. I don't think you can run it without the fuel tuner if you don't have a flashed ECU.

I think preacher's suggestion to unplug the rad fan might be a good one just to see if that makes a difference. Would be careful about overheating though if you have hot weather, so next time it happens see if you unplug the rad fan if it starts right up.

Thanks everyone, it was oddly enough not acting up even in this summer weather until it did once. I figured i’d give the fan plug a pull to see if i got any more juice only to discover i had just acquired a nice big rock embedded halfway through the radiator and leaking everywhere. kinda lucky in a way. soooo got the new one in today and def lyk if i find any answers. (made a wire mesh guard for $14 to keep rocks out 😎) thanks again 2️⃣👇

I did the same with a mesh guard with much smaller holes and it saved my bacon one day. Outside of Dawson City Yukon they had road construction and there was so much clay and rock stuck to my rad I had to pry it out like a brick.

Today I came out after work and noticed a large long thing sticking out under my bike. Turns out I picked up a tree branch around the size of my pinkie finger in diameter that had slammed into the rad, wedged up and under the plastic fin cover and would have really mangled my rad fins if it wasn't for the mesh guard.
