Hi all no laughing its a question about a 50cc ped

[Ashtec]

Hi all and I hope some one can help
I've just got a typhoon 50cc moped 57 plate it was cheep as it has a small issue with a lack of power after a couple of mins of riding. Any way I'm not going to look in to the fault as its most likely fuel related or sticky rings as its. It's not been used for a long time.

I'm going to use it was a work hack and so I can get through the traffic going home at lunch to sort the dog out and have dinner

I'm thinking Of getting a 70cc bore kit for it 21mm carb and matching read block and manifold and sports exhaust. My question is can some one with experience point me in the Right direction with the carb jetting mainly main jet and needle number and height ?
Many thanks ash

Hello

If you need more CC, sell ped and buy a motorcycle/Ped with larger CC engine.

Fettling the engine will likely result in poor reliability and poor running, which isn't what you need for a work commuter.

Will also probably push the insurance up alot (if its being noted on insurance)

Best to just sell it on and try and nab a cheap Honda CG or similar

Honestly save the heartache and get a 125. Apart from anything else if you increase the bore beyond 49cc the ped becomes a motorcycle and needs re-registering as such with the DVLA to stay road-legal.
More to the point, skittle a kiddie on your 70cc 'Ped' and you're in deep trouble, like permitting an unroadworthy vehicle to be used on a public road, driving without insurance, etc...

Hey all you not really answering the question lol

At 30 years old and my commute to work is a whopping one mile and the 57 plate ped owes me £40 reliability is not really a issue I only want it as it will save my using my car or Ktm excf 250
And It has a running fault so after looking at the price for a engine rebuild for all the race parts I'm thinking it a be funny to throw some money at it and tune up a 50 like I should have done when I had my dt50 as a nipper lol
I'm in the automotive industry and have insurance to ride or dive any thing I have a license for

So if you don't rearly have much constructive input other than the law the reliability and saying I should get a bigger bike bla bla bla pleas keep your advice
But if you know a rough start on jetting for the upgrades I intend to get I've very much like to hear what you have to say
Thanks ash.

PM tuning sell pre-jetted 21mm carb kits that will get you in the ballpark, however guestimate (assuming you're running a pod filter) that you'll be running 115-120 on the main. Idle jet will be a ?? and needle height, well you'll just have to play with that till it runs okay.

You may find these threads interesting.

Also, my tuned ped runs at around 15mpg, so commuting by car would probbably be cheaper. Do it anyway, it's addictive and really good fun.

Andy hates peds & is very very boring. He'll interrupt every ped thread with some bullshit about killing kittens, re-registering with DVLA blah blah for some reason.

You'd do well to ignore him & build a 70cc wheelie monster - https://www.youtube.com/watch?v=3quc0vcCckk

Finally a sensible answer
Thanks Iain
15 mpg out of a 50cc ped haha I'd take that as an achievement in its own right.
But that's the same as my 1.9tdi pd golf is getting as I'm mostly stuck in traffic so the ped would be better for me that way.

If it loses power after a couple of minutes, surely it doesn't matter as you've already covered the one mile commute anyway at 30 mph?

1 miles journey? Why not just walk it?

think he may find his front brake work better when the wheel is on the ground

I used to live 2 1/2 miles from work and, like you, thought that walking to work was stupid.

Unlike you, I MTFU'd and rode an FZ750 the 2 1/2 miles each way.

I walk the dog 3 miles every day so it's not like I don't walk
But I don't think I could walk that early in the morning. Luckily I have a French bulldog and he is not getting off his bed till lunch time.
