thanks paul yeah all levels are correct,on another note im wondering should the bike have a cooling fan,we were out the other day with someone with the same bike but its an 06 his has a cooling fan,now our bike does get hot but i thought this was normal but my friend recons its too hot,should it have a fan or was the fan added to later models.thanks

thanks for the replies guys,i did see the 70cc upgrade kit mentioned on here il have a look at that in the next few months,whats the best way to to check if ts using water. on the gear box oil bit i had a look and the gearbox oil window the level seems low to me i would say it is less than half of the circular viewing window is this too low. thanks again guys

hi so i got my son the txt boy,after a quick run on it realised that it lacked power so i came on here and there are a few posts with suggestions (60 tooth sprocket,air filter mod and thicker clutch plate) one other thing i noticed after looking at vids of other txt 50 i noticed this one smokes quite a bit (white smoke) does this indicate wrong oil mix,the guy i bought it from used 50:1 but ive seen some people on here running 70:1,any suggestions on the white smoke and what mix to use. many thanks
