@kingzaki bro i know what you mean. I agree that one should not spend on something which can leave you in middle of a road. But for that matter you have to keep it maintained ( same is the case with any ride, if you dont maintain it, it can give you problems any where).
As for me, i got my bike restored from karachi because it was easy for me as my friends are at karachi and they know some good Honda Road Master mechanics. Those mechanics are expert in dealing with Road Masters. I can give you the contact details of my mechanic who restored my bike ( please note i spent too much money as i get this thing restored for myself and for my satisfaction) it was not built for reselling. So i bought each and every thing which was A+ in quality, even the chrome i got was of good quality ( in terms of baring high temperatures)... at the end all what matters is the ride and feel of the bike.
If you are living in peshawar i would recommend that before buying do check the mechanics who can work on road masters. In islamabad i have 2 guys here who are good for Road master.
I have not yet completed the running of my bike, so probably in a week or so i will be visiting them to get every thing checked.

This guy is asking for 90k but every thing of this bike is in perfect condition (good thing is he said i can negotiate a little more if the buyer is true admirer of RMs), i hope you wont be having any problems with this bike( provided you buy it and keep it maintained)
And thanks for appreciating my bike... 
Mashallah and Alhamdulillah i get this comment almost every day i take out my bike.
Since i enjoy its ride... thats all i wanted so its a money well spent for me.
