typhoon 125 top speed 63mph???

Got a 52 rolling nut tph 125 with a carbon reed, pm 360, 12.5 rollers, 102 jet, malossi red filter, I can get to 60 rapid then creep to 63, 64, and down hill 69. I clocked today if I ease of the throttle nearly quatre turn it does same speed but a shit load quieter, when I open it up again it gets louder but goes no faster almost feels slower ? Is that all she has or should I ever see 75 mph on the clock? If so what is the answer? Thanks guys I will wait for replys patiently

 

Main jet is to big, std typhoon is booked at about 62mph, 75 is a bit optimistic.

 

To be honest the main jet sounds big, as MARSH says, but my typhoon 125 will get to 60 pretty quickly but it does hit 75 if I tuck in.... But again this is only clock speed!

 

lol i hear that lads, thanks for your input also, i just got a dello 25mm gana fit it and run it on that till i get the 172 kit next couple of weeks, is there anything i need to know or will she run fine with a 25mm carb on a 125 bore?

 

I'd leave the std carb on it with the std barrel, also the std carb will work fine with a 172 kit, just upjet to around a 92 main jet. worth a try!

 

What should I be expecting to see on my speedo is what im trying to sort of find out so I know if its running good as it should be
