Did anyone find a solution to this problem as I’m having the exact same issues on my race bike. I’m running a powercommander5 with revextend to 11000rpm. I’ve been told that the standard ecu will cut the ignition if it’s over the standard rev limit of 10250rpm for longer than 3 seconds as a...
I just had a rod on a 2015 model stretch. The small end hole elongated around 5 thou causing excessive piston side wobble. Caught it in time as the engine had a knocking sound at idle which I thought might be the clutch as it seemed to go as the revs increased.
KTM must have known of the issue...
Very good. Nice to see some newfound appreciation for the 390. Ive raced one for 4 seasons and I still have a blast on it. Yes 3 head gaskets, ( yours should be a bit better as that model has the bridge) gearbox jumping out of 4th and intermittent ignition problems but its still a great little...
My mate has the rapid bike race fitted to his and he is suffering from a glitch where his bike is cutting out like its hitting the limiter at around 9500. Try and see if you can see on the tacho when yours cuts in. You may be suffering the same issue? When he disconnects the rapid bike the bike...
Ive done 6000 race km on 2 head gaskets on the early 2015 heads. The first gasket was the old part no and the second was the new part. On both Ive used a coppercoat gasket spray. Im just about to pull my motor down for the winter break to change the head gasket again as its showing very minor...
I modified my snorkel to the same dimensions as the race model and am running an open lid with PCV and WB2 autotune
Im noticing a slight miss around 8500-9000rpm at full throttle.
Would this be caused by the standard injector. There is more room in the PCV tables for me to add more fuel or is...
I also notice Hotbodiesracing make the wss300 fairings. It shows ramair scoops on the inside of the side fairing panels.
Is it actually pressurised Ram air or just a cool air duct?
Regarding the difference I noticed in the head gaskets,
The original one installed that blew had a rubberised coating on both sides and that is what actually blew out.
The upgraded gasket didnt have the rubberised coating but has like an anodised finish.
I blew a head gasket between the exhaust valves into the coolant jacket on my 2015.
I used the updated ktm gasket and also used the copper spray to coat it.
My head h
ad a slight hollow in the spot it blew of about .001 inch
I used a thick piece of glass with 600 grit emery paper taped to the...
Fantastic, Im keen to see the dyno results. I think thats where some of the extra ponies are in the 390R.
The continual expanding dia is the key I think (reverse supercharging). If you check out all the moto3 bikes pipes, they are using the same tech.
I also noticed in the WSS300 regs that cam...
How much thinner is the Cometic to the standard KTM gasket?
I did read somewhere that there was a KTM Race gasket that had one layer of metal less in its construction, therefore thinner?
