Peugeot Speedfight

[SpeedfightBoi]

Hi I have been lurking around on this forum for quite a while and have just decided to register to such a wonderful forum (Y)

I have just purchased an 07 Peugeot Speedfight 2 50cc.

The bloke says it is de-restricted, has a race pipe(leo vince TT) which is also de-restricted and has 6.7 gram Leo Vince race rollers- But only goes 42mph on the flat.....Surely it should go faster than that? I have pm'ed him and he says he weighs 12 stone. What are your views on it guys

Thanks in advance

I would say it should hit 45mph.

Sounds to me like the exhaust is still restricted. Mine will do 42ish and I've still got a restricted exhaust.

You'll have to take it off and see if there is a washer welded in the exhaust where it meets the head.

Piece of piss to get the exhaust of Speedfights though. 3 nuts in the seat bucket, 2 nuts where the exhaust attaches to the engine and 2 allen bolts where the exahust bracket attaches to the engine.

The bracket may be different though, I'm going off what a standard speedfight exhaust has.

there is also a washer in the variator casingthats a link on how to remove it and also about desrestricting 50cc bikes
hope it helps

Thanks for the replies guys...When i collected the bike, the small tube thing from the exhaust was in a bag.. with drill scuff marks on it which he removed from the exhaust and also the 10p sized washer was in a seperate bag along with the old rollers. So i asked him why it only does that speed he had no idea :S

Could be to do with the roller weights but I'm not much of an expert when it comes to the weights.

[matt46cars]

lighter weight rollers are for acceleration and heavier rollers are for top end
i have an aerox with deristricted exhaust,deristricted variator and 2x 3gram rollers and 1x 8 gram and bike has loads of both acceleration and top end and flys round the clock and does about 60+

the rollers could be worn. i had a 05 speedfight 2 and its top speed was 50mph and its acceleration was very good (for a scoot) i was changing rollers every 2500 miles, but i must state buy genuin peugeot rollers! i tried others ones and i had some even melt in the variator. peugeot rollers are 8grams and they are the best settup, do not even change the springs in the clutch.

heres a vid of mine, (sold now) https://www.youtube.com/watch?v=4bfC5OioucQ

oh and to add, it had leovince TT, 0.80 main jet and a K&N style. standard are 0.50 main jet

i think there slow bikes in general (no offence) its probably just set up badly, get some one who knows what there doing to play with the set up for you, unless you have the cash to splash on getting it set up on a dyno (no point at that stage of tunning)

The best thing to do it to check if the variator is rectricted or not you can tell as soon as u look at it when u take the cover of. Also check the exhaust that may still be restricted. It does sound like your exhaust is still restricted however if you revs are still restricted you may as well de-restrict ur cdi as well
