100cc speedy Bigbore???

How greatly would the performance increase with a 120 bore on my 100 speedy, its got a sporty, K&N filter, and slightly heavier rollers if it helps lol

cheers

 

To be honest mate, my friend has a 120 bore on his speedy and it hasn't made hardly any difference. A 50 speedy with a decent 70 kit, pipe an carb would most probably have a 100/120 up to 55-60.

I THINK!!! Don't quote me on it.

 

alright buddy... tbh i want my bike hitting 80ish then i'm happy... but speedo sticks at 51 even tho i can feel accelleration still burning on up so i'm not entirely sure on speed at the mo... but im guessing around70 since i can overtake on the dually with relative ease :unsure:

 

Need a miracle to hit 80 on that mate. I mean, a 125 runner will only hit 75.

 

ah i see ... so i will also assume that im not looking quite at 70?? or u reckon thats about right?

u reccomend any exhaust for a speedy100?

 

probs about 60

 

mate had a 100 speedy, went 60 got there rather rapid tho

 

60? nah its quicker than that... mates 50 aerox gets 55 and m8s rs50 63 GPS clocked and i do them both with ease... but without a working speedo or GPS clocking not sure =\

wat can you recommend to get my top end higher?
also i dnt seem to get much power to the wheels (unsure if thats the correct term but we'll see ) if i whack on the front brake and push the bike forward and give shit loads of revs it doesnt wheelspin/burnout, whereas m8s 50's do? would this be from heavy rollers? gearing? im not an expert but these kinda make sense to me :L x

 

lol cheers for that very technical input graham :L

wat can i do to fix this?? and im very aware of your speedfight disliking so new bike isnt an option

 

lol the size of pug inlets is laughable its tiny. i think a mate of mine has a 120 kit somewhere he had it on his bike and it was nippy untill he crashed it

 

oryt sound will get on that 1 then pretty pronto... so wud u say 120 bore worth it or not? i can get a polini/mallossi (not sure which) for about 120ish including fitting??

 

60mph is max on ones of theses

123/120cc borekit does fuck all. imp:

 

there realy down geared aswell, so look for a gear up

 

welll im beating my mates RS50 which is doing about 65 GPS clocked not dodgy speedo... so im guessing over 65

 

the the gps needs re calibrating

 

in all honesty you can throw £500 at the speedy, gain 10mph and smile, or throw £200 at it, chop the motor in for a piaggio 125 motor and smile just as much for less than half the cost (then you can buy a 172 and a big carb with the spare pennies).

 

tbh im gettin kinda annoyed with my bike anyway :L... so wat would u recommend? pretty cheap looks good responsive to tuning?

 

Gilera Runner, Piaggio Typhoon. Both 125
