Ansee yar I dont mean to offend is liye mind na kerain but think for a instance (I have bolded it) ....
If you remember back in some thread I shared this pic of GS and I also asked @imran_bhatti to have some comments from him, GS does have a top speed every body know but the problems which I mentioned below are not ignorable and kill the passion of race which exist in Rx, GtO, YB, CG but Deluxe, GS and paiggio lack it big time .. :

First of all 2 miles (+3.21 KM) bro ???? I mean its to long to race Diesel Truck or a train engine you know, I mean a 5 feat long bike really should need this long track for beating a smaller cc bike ?
just think for a second ? even in international Speed freaks like Top Gear and other use a quarter Mile Airstrip or even less ...
"Although a quarter mile (402 m) is the best known measure for a drag track, many tracks are eighth mile (201 m) tracks, and the premiere classes will run 1,000 foot (304.8m) races. The race is begun from a standing start which allows three factors to affect the outcome of the race: reaction time, torque, and traction."

I mean being a GS owner you can not mess up with any CG untill you have at least 4 miles in front of you or CG with even smaller build and cc would simple beats you out before you GS start to catch up.. ???
I am not sure but it seems to be that you happen to have very poor performing CGs among the racing 98~100 to wo CG bhi ker letien hain jinka break in period kharab guzra ho ya jinka carb ya Plug tuned naho...
because I have seen totally different cases :
1 - CG 124 power plus and EII both breaked in properly with GS150 breaked in and a checked cruiser in GPS at 115~116KM.
2 - Both CGs were tested separately old CG had 104 top and new one had 109 top speed
1st gear: CG Pull ahead (CG gives Gap or roughly 10 meters reaches redline after 35+ stays ahead)
2nd gear: CG maintains (CG maintains Gap uptill 60+ )
3rd gear: CG Increase Gap more as GS changes gears (here Gap goes to increase again GS has to go for 4th gear due to smaller gear ratio to maintain but CG takes advantage of longer 3rd gear and increase gap reaches some where 85 + )
4th gear: Finally GS Catches Up !! (CG final gear here engine feels the pressure reaches 100 quickly but crawls across 100+km/h.... GS still around 15~20meter on tail but now catching up and is in 5th gear takes like a complete 500m/half KM to get head to head with CG and then cross it I mean itna time or itni lambi road ho tu he ja ker baat banti hai GS ki lol
)
PS. Now thats not what happened every time becuase in some attempts CG made bad gear shifts and GS left no change to take the lead.
