royal enfield 500 efi Power increase

[ngj874]

My mate has a royal enfield 500 with a side car. Problem is with all that extra weight and drag the bike struggles to do 100 kph. Stock power is 27 hp but would like to bring it close to 40hp. Bike already has a free flow pipe on.

Anyone have any idea on what performance mods can be done and where the parts can be bought for this royal enfield?
