I am for the muscle building plan, already need to eat rosh incase I plan for hunt on mog :). So stage 1 for building muscle is to start off with some heavy n faty n delcious food and let's plan that first on place and the excercises later 
Regarding BeeMog's turn, I am up for the test, operation should take place in Lahore, pls check the availability of parts and let's do it.
However, after doing above upgrade I still have the question mark over 12.5X20 hieght, my preferrence is lower profile and personally I like the tyres installed by Doctor Sb.
@Doc Sb. Why do you want to change them? If age is the factor then And what's ur thought on installing the same tyre again in fresh?
