Runner 172 question.

Hi, I had bought a runner 180 and made this setup :
Malossi 172 , with selfmade piston (a copy of original , but has only 1 piston ring(on dyno +1hp))
mazuchelli (smth like that) 54mm crank,
malossi vario 13.5g rollers
polini maxispeed cluch
Technigas rs180 pipe,
stock 20.5mm carb.
so i can't reach more than 84mile/h
and can't make a power wheelie.
I would like to reach 100mile/h and make a power wheelie , what should I do ? any help?

 

I forgot to tell other problem, with stock filter runner goes nicely , with free inlet one it goes crazy on powerwheelie , but on 20m/h it loses all the power , and I cant pull ther throttle , if i do - it dies.

 

oooh my God cratch:

Over to you Minor and company and good luck im off to Pod for the weekend :amen:

 

i think i need stitches can we please make this a sticky so i can read it everytime i come on :lol:

 

i think your lucky to get 80

 

you have a 180/172 with a bodged up piston that doesn' t powerwheely hmm?

 

lol im amazed

 

lool was that aimed at me lee?

whats it jetted to and did you change the jet when you put as filter on it ?

 

I had changed jet to 98 , it runned cool ,but it woun't start up after night... so I chaged it back., today I had reached 100mile/h. i had put a 36mm carb from my friends olr aprilia rs., I checked a speed with my r1 , and friends gsxr , the speed were 100m/h. , Icant do powerwheelie , but I can reach the high speed. what should I do?

 

i dunno then?

them rollers seem light to me i dunno why it dont wheely
what springs yyou have and how long the rollers been in there?

 

lol at 100mph clockspeed

 

my 180 used to do the clock in standard form lol.

 

not aimed at ya just pointing it out

 

its probly chemical metal or summin the thesecond groove

 

I have original malossi piston, but that where I made myself, I used a nother piston 66mm diameter. I made a form simmilar to a original one , actually it looks same as original, only with one ring

 

:worthless:

 

me thinks its just a waste off time to read this post ,without pics off piston ,1 bhp on dyno y didnt you set you carb up when you had it on the dyno
