Need Advice on Tweaking a Royal Enfield Bullet

Hello Team, Attachment 846308 Here is my father's early 80's Bullet. Its not really been used much so I decided to take over :D. It was overhauled sometime ago, while I was studying in the Amreeka, so couldnt really influence anything... Now I need your help... I have issues with the ride height. Although, I can still ride, its not to my liking. Also I feel the gap between the wheel and the mudguard looks completely out of place. So here are the problem areas I need to sort out: 1> Attachment 846309 How can I reduce the gap between the wheel and the mudguard? I noticed the assembly is an individual piece which connects to the chassis and the mudguard. In that case, can I get a different assembly which has a lower curvature? 2> Another issue I feel is the seat. Im planning to get the stock two piece seat assembly from the new Classic350/500. Will this help lower the ride height? The seat looks a little low profile but I cant really make out from the pictures. 3> Attachment 846310 I feel they have changed the handle bar as well... Its bent upwards and I dont think thats how the stock handle is supposed to be. 4> I want to upgrade the rear drum brakes and get a disk brake assembly for the front. Also whats the widest rear tyre I can get for a good balance between stability and performance? Are the stock Classic350/500 tyres good enough? I am eagerly waiting for your tips/suggestions. Also I am from Pune and would appreciate any references to good mechanics/workshops who can help me out with these tweaks and source the parts as required... Attached Thumbnails
