there's your problem. also having ctr cams doesn't help your cause either. BTW what did you expect when you started to modify your engine? 35+ miles to a gallon?

 

previously for about 6 month, its running good....fuel consumptions is not too bad, can go for 400km for full tanks......rite only 220km per full tanks....very bad consumptions.....
