On the rebuild a high compression gasket was installed and the valve clearances were set tight, .6 and .1, is this to get more out of the higher compression or do I need to correct this?
So given that the spec range for clearances on both intake and exhaust is 0.04mm and shims come in increments of 0.05mm I have an issue getting my bike within the recommended range. All my valves are just under spec on the tight side. Ideally I'd set them in the middle of the spec range however...
I though I would post this, to help wondering minds save some cash...

Cliff notes are that titanium valves don't perform well on the exhaust side for motors that run hot. Titanium can be used on the intake side, but unless an alcohol...
Hello,
I would appreciate some input from more experienced members here. I had check the valve clearances and I found that all four valves are out of specs and pretty tight. Both intake valves were only 0.04mm and both exhaust valves were 0.08mm.
Now since the dealer has shims that are...
Hi all, I'm working through my first valve adjustment with the RC. Second owner and the original didn't have anything for records so I'm going to assume never had valves checked (12,000km). After pulling everything apart I was tight on all 4 valves by either .01 or .02mm, not a big deal. So I...
Hey, wondering what everyone does for winter maintenance on the RC and any recommendations. last year was my first year racing one.. on my R6 i would do valves and clean it up, + refresh the forks / shock, but thats about it.
Anything else i should be doing on the RC?
I am planning on doing...
Hello everyone
Hope your all well :) ,,, We are now enjoying hot weather in the UK ,, YEEP PEEEEE LOL.......
Guys I took my bike to the ktm dealer Tuesday to have the valves adjusted so I can at last ride my new bike now ,,, I took it over there in a van my boss kindly let me use.
OK I...
my bike is 2015 cup bike I got it new in 2015, it has about 15 sprint races on it and a probably about 10 track days, i check valves religiously and oil changes are done after every outing, the one thing i have never bother to check is the cam sprocket bolts, well the intake bolt decided to back...
while refreshing the cylinder head on one of our rc390cup bikes we came across one inlet valve cracked so we ordered two valve kits from ktm when these arrived we check them for stem to seat run out to find 5 of the 8 where bent and not useable and contacted ktm uk to be told that they had no...
Hi Friends
I bought a 2015 RC-390 for daily use (have MV Agusta Dragster for weekends)
But, for safety reasons, I want a louder exhausts, that will not braking the valves in terms of lack of "back pressure" or lean mixture
I love the under belly options (such as GPR ghost), or the GP style...
Hello
I would like to study a possible exhaust, and I'm looking for valves timing.
It is not in the owner manual, and I'm surprised to not find it either inside the KTM Workshop manual.
Is there any technical litterature (similar to Haynes manual) about our prefered bike?
The engine stability...
At 15,684 miles I decided I had punished the KTM's mill long enough. I broke down and adjusted the valves. Of course, this required the acquisition of Harbor Freight's 1,000 # motorcycle lift that taunts us with that $299.99 coupon each month in the back of the MC mags. It's sweet!
It all went...
