Yes, I have also seen that bend clip On handle bar cause for pain in shoulder. Also, CBR do need 331ml 10W grade oil in each fork (which most of the mechanic don't know).
Have you replaced the radiator fan as well. What I heard from part supplier that, CBR250R fan get damaged from center (where it was attached to Fan motor), due to which fan stuck to back side of radiator.Update:
Got the handle bend corrected. The issue was with the handle tree or T. It was bent. The mech got it sorted out. Plus have changed the rear tyre to Apollo H1 150/60 R17. Changed the front tyre to stock size from Apollo as well.
The cornering and grip has improved phenomenally from the earlier contigo tyres. The earlier tyres use to skid a bit on cornering.
Time to put some miles on it now.
I have ordered the fan (requires min. 20 atleast due to parts shortage here in India), once the fan arrive i will open start removal process and update the results with photos.The fan may have come off the axis. From what I've seen, this connection is very delicate, but also very strong (relative to the forces applied there), but maybe that's what happened to your fan, that the fan came loose from the axis and stuck to the radiator ribs?
So mean to say, I can fix this using Loctite 680 and M3 nut, that's great fix. But need precision so that fan rotate staight (perpendicular to motor axis). Anyway ordered the fan (which is really cost real cheap).
