I rerouted the breather so as to keep any oil misting from fouling the air filter. Call it an old habit from running older machines back in the day. On the UCE motors, aiming the crankcase fumes away from the intake tract is still preferable to to the stock setup, especially for folks that run their machines hard.
Fer today's tinker project. I pulled off & cleaned the exhaust system, then sealed the joints with high temp silicone to ensure no sooty leaks. (It was wet out anywho, so what the fook, get 'er done.)
The EFI has a very good trap below the hose inside the cases and won't spit oil out if it is at the correct level in the engine. I certainly do not get oil in the airbox and having the breather feed in there has been around for years, It's not an older motor, it is supposed to improve performance not be detrimental.
I don't think I thrash my bike, I've got it tuned to the stage where I don't have to. Nor do I think I ride particularly fast, I certainly do not enjoy riding too fast, but looking at some of the videos online I seem to go a wee bit quicker than they do on the same type of roads. The art of going quickly is to ride smoothly as it were, not giving it full chat all the time.
There is no silicone goo on my bike. Copper gasket p/n 582638/A (a genuine RE part) seals pipe to head properly unlike the useless cement biscuit thing. The silencer clamp goes around just below and on the end of the slots to compress the pipe, if it is put on the middle of the slots there is a gap. No silicone required.
As for what I'm doing with the C5 - I think I'm planning to save the maps and take the PCV and Autotune back to square one to determine what the engine is actually trying to do (it looks too rich now) and start over with the mapping whilst incorporating what I've already learnt from the current mapping.
You see, running a dyno on it just determines the mapping for maximum power and we don't always want that, it's not a high revving engine so we want powerful mid-range torque as well as providing power up at 6000rpm. 34bhp is possible and just about right for this bike, but we get way more torque than a Velo Venom.
