Too bad about the fifth speed bridging!
I found a preparer that passes the butterfly body to 47mm, is that the dimension I need in the BIG 3?
In EFI case, the PC5 is the best?(+autotune?)
In an air filter, I saw that the KN and other air filters of the same type were not the best.
A foam filter TWINAIR +air box cover KN is OK for the BIG 3?
I am also looking for a camshaft but difficult to find for models 2018.
For road use, level 3 is more suitable I think?
I donít want to lose reliability.
A 38 tooth may make a positive difference if you have enough chain.
As said before, the Big 3 is fuel controller, full exhaust and improved air cleaner. The K&N air filter has been shown to pass fine particles. There are similar K&N "style" filters that have more gauze layers and do a better job. Or, the foam filter is another option. But I always use a pre-filter. What ever your decision, be careful of over oiling.
Now, when you "add" a bigger throttle body that's a Big 1, and a cam is another Big 1. With all combined that is called the Big 5 and is done in that order.
Yes, the throttle body can be bored to 47mm, but be sure the machinist knows that a new throttle blade needs to be fabricated with angled edges and the shaft needs machined too.
Your 2018 already has a higher compression piston, so the Stage 3 cam will be a good choice for medium to high speeds. No special valves or springs are required. Slower speeds may benefit from the Stage 2, but I see no reason to use a Stage 1.
Your next performance gains would be head porting and a 11:1 compression piston. None of these modifications with a good map will affect reliability.
