That was the most noticeable upgrade. You can see from the graph. That at higher rpms TID12-07 (part nr. 12R-10 #622) ignition angle is constant.
But keep in mind, that to get more power air/fuel mixture flow must be increased.
So 12R intake boots are a must upgrade :)
Found old pictures from my archive.
As you can see 12E intake boots are very restrictive.
Also the best performance upgrade was the ignition module swap (plug and play). With restricted module engine was really struggling to rev high enough.
After swap, engine easily hit 10k mark at load and...
I'm also dealing with derestriction of my bike (12E)
I'm half way there :D
On restricted version the exhaust camshaft has marking (E) engraved.
Also Check your ignition module. There are two versions available.
Cleaned and rebuilt front fork. Put new oil seals and boots with some fresh oil.
Oil level was so low I managed to get 0,3L from both tubes. And both tubes had oil in different collors (green/black). That might explain why frontend seemed mushy and bottomed out at breaking/bigger pothole :banghead:
