i went for a ride with jamiekellard today and my 18 is quicker than his 21sp,i cant pull on him when we open it up,the gap stays the same but as we get towards the power mine pulls harder and im able to catch him and pass,i dont know what gearing we are running,he is running jha pipes and a m-max box,mine has stock pipes and a modified air box but stock jetting,i dont know what jetting he has but i think it must have been rejetted because of the pipes ,i think he would need to do the airbox mod.

what about this then,we both had full tanks when we started out and then later on refilled at the same time,his took £5 to refill and mine took £10.50 worth to refill,can this difference in the amount of fuel used be because i have a modified air box and his has a stock one?im just surprised to see how much fuel i used compared to jamie.
