1 - Spark plug 100% get it replaced I did that on the same day I bought
it...
2 - remove air from them get the tyre trek to the correct position fill air rotate to confirm there is no bubble effect (do keep in mind this is a big bike it has bigger tred tyres and need to fill carefully to fit properly on the RIM) bruttle and ignorant mechnic mostly make bubble while filling them..
Now as bubbles are gone go to the back of the bike while keepin it on the main stand and sit down exactly in line of the both tyre and see if they are in line (I am 100% sure the rear tyre will be out of line...) losen its main Bolt~nut and adjust it to inline with front tyre... (YOUR DONE AND ALMOST READY TO ROLL Like hell fire now)
3 - This is true with every disc brake bike as pads are new and Brake oil is topped up so it is very likely to have heavy rolling tyre , do check the rear tyre as well, may be its tight too...
Solution : Front Disc, bleed it only a little and youre done, rear wheel loosen the brake rod DONE! keep in mind both wheels must be free rolling
4 - 200 km in 3 days :
o:o:o:o WT fish Man!!!! comon brake it properly I hope you are not not exceeding 70~80 kmh... dont so it... or you will never be able to achieve its maximum potential of crossing 110KMH barier....
Drive safe..
Glad you are facing maniture assemlbly issue, I had one major issue of bad chain cover...
