I am a 52 yr old novice rider (only 10 years riding), I weigh 220 lbs, and, I have 2008 CRF 450Rs that feel so good and balanced to me. On one of the bikes I have an engine that a famous engine builder created - close to 60 hp is my guess. I love this engine - with my size and weight especially. It has the flattest power curve of any type of car or bike I have experience with. It is being rebuilt now - it has MANY hours on it.
Here is the question (thank you for your thoughts on this). I have increased the idle to annoying levels (it annoys others around me), but, coming into tight corners, from high speeds (especially on race day) I stall this bike when the other identical bikes I have (except for the engine on the other bikes) do not stall.
I am thinking of putting a Rekluse clutch in along with the rebuild.
Do I need to learn how to ride better, and, dismiss this idea of a Rekluse?
Are highly modified, high horsepower engines more difficult to ride typically?
Thanks

If the race engine has a high compression piston or a decked head, that can contribute to the stalling at idle.
However, that bike should not be stalling even with the stock clutch system. As MXD stated, the pilot Circuit and/or fuel mixture screw on the carburetor needs tuning.
Nothing against the Rekluse clutch, but that should be your third or fourth step to the solution.
I found as many of the remaining factory parts as I could which was made easier as the switch to EFI made the old carb stuff obsolete, and ended up putting it on a dyno to get the fueling dialed in as the carb had been bored and modified. I also started riding it more like it was intended, beating on it a bit more. I tried a Rekluse, which at the time was the version with the ball bearings and the bike really didn't like it and ended up frying the thing - blue plates etc, even on the aggressive most setting and stiffest springs. The new Rekluse clutches are way better though, so I wouldn't have thought you would have this problem.
I still own the KXF but I got fed up with it and bought a 2012 CRF250, a bike that is renowned for being slow because it is. Remapped it, added a pipe and I love the thing, so also still own it. The Honda is smoother and easier to ride, and my lap times are improved on it.
Yes.

You guys who are too fast for Rekluse got more speed than top Pro off road riders? Please...
It could be as simple as a carburetor or valve clearance issue as well, I'd maybe start there.
