This was a common mod by us in the 2005-2010 era. To lighten our bikes (about 15 kilos lighter ... which is great in the mountains), by replacing a lot of the heavier tin work with plastics. Put on a nice free flow Goldie (BSA Goldstar exhaust copy, fabricated in Poona by Shakeel), and pair it with a free flowing K&N paper element cone pod filter or a oiled bi-foam dirt motocross style UNI pod filter (from dune buddy racing applications).
Fly mudguards. For mud clearance in slush (Rohtang onwards ... those days it was the Wild West. No roads. Just snow and slush and rocks and raging torrents of snow melt. And black ice!). My mechanic (Rafiq mama) and I retrofitted a Yamaha FZ ka back end mudguard/licence plate/tail light/indicators cluster to the Bullet and it came out beautiful! She was one of the best modded Bullets in the country then. Shes back to stock now.
