Pedstop 94cc Pitbike hybrid with automatic Race engine - Update

Pit Bike 94cc
Over a year has passed since we mentioned our hybrid 94cc automatic Pitbike x scooter and lots of things have changed including my thinking.
Did we finish it? Was it any good? Yes it was and is, so why no updates?

This thing is a beast, handles well, extremely fast and possibly too much fun, HOWEVER wearing no helmet doing 80-90mph in a cold wet, dark car park wearing a t-shirt and jeans with no gloves isn’t something I would ever repeat especially when it results in an off.

ALWAYS WEAR A HELMET KIDS or you might end up with brain damage, severe deafness, fractured ribs, arms and maybe even triple vision. Did I mention the lack of patience and the need to swear at just about everything I don’t like, Fuck it lets show you some pictures now it’s been rebuilt and I’m conscious.

The Beginning
KLX 140 Pitbike was chopped for the fork tube and rake; Pit bikes are great on tarmac with sticky tyres on. Keeping the Pitbike front section retained the original geometry be it looking a bit different.

The Engine
We robbed the engine from our Polini 94cc Piaggio Zip which we love, Polini Big Evolution 94cc, 52mm piston with 44mm long stroke Polini Evolution crankshaft. Polini digital ignition with Big Evo exhaust, 9 roller variator, 33mm Keihin carburettor from a Yamaha Banshee 350cc quad. Bespoke petrol and expansion tank with an oversized radiator also taken from one of our race scooters.

 

The Frame
I better mention the chap that fabricated the frame for us from some very sketchy sketches “Fat Shaun” sorry Shaun I meant Fatspeed now in their new unit fabricating one off motorcycle specials Down and Out Café Racers. Not the usual for these guys but frames are frames especially when it’s something quirky like a Pit Bike.
All of the pictures above are of the now repaired bike “Post Accident” almost as a good as before with the help of some insulating tape and not so perfect cable routing. The seat has been recovered as this wasn’t bolted down during the first test session so took some damage; in fact ha ah that’s what did my ribs.
What next, well we want to see it go around a track just like you with a good pilot not some old arse wannabee like me. Anyways we really can’t risk wrecking it again it’s so pretty. We have somebody in mind that can go around a track fast on pretty much anything and he’s young so he will bounce better than any of us.

If you think you are the pilot we have in mind then give us a call and ask for Chris

Pedmoto Series 2 exhaust for Gilera Runner and Piaggio Zip MK2

The Series 2 is here not only with an amended silencer logo but with improved torque and redesigned expansion allowing fitment throughout the Piaggio, Gilera and Aprilia scooter range including the early years.

Each system is maintaining the £99 price tag and includes variator rollers and all other components needed to fit.
A jet increase will be essential on stock 50cc scooters, here is a link to the product for more information PMS1860

Here is a link to the exhaust shootout from July 2012 that explains a little about the true operating RPM of the series 1 and 2 and why this makes life easy for any DIY scooter tuner. Shootout

Derestrict a Tecnigas GP 4 exhaust system

This is a short blog just to make it a little easier for you guys trying to make that 4 stroke engine breath a little easier and give more performance when using the Tecnigas GP 4 exhaust.

In most homologated exhaust systems there is a restriction at the manifold connection which meets the cylinder, the GP4 exhaust from Tecnigas is different.

The GP4 has been restricted on the exit of the system, the hole is very small and gives a similar effect to the normal restriction. You could call it an alloy spacer, washer or bush, regardless of name it needs to come out if you want to get beyond 30mph.

The crudest way and by far the quickest is to simply insert a bar or even a screwdriver with almost the same diameter into the washer hole making sure when you push it in you don't make contact with the baffle tube. WD40 would be useful making it easier to work the washer out using a rotational movement.

Once out the system will be free from restrictions enabling an increase in top speed making your journey that bit safer. The sound tone will also change, we think it's more in line with what you would expect a 4 stroke to sound like.

Derestrict a Piaggio 50cc 4 stroke scooter, Zip, Fly, Vespa with a CDI

Single cylinder 4 stroke scooters like the Piaggio Zip, Fly and Vespa S and LX etc have been hampered in their already feeble performance with some other niggles just to make sure you really know that you are going slow enough for a cyclist to overtake you.

The obvious restrictions are in the variator and the exhaust system, which are easily changed or removed, here is a link to show you what should be removed from the transmission on a 2 stroke engine which is exactly the same principle for your 4 stroke,  follow step 4 and 5 .

The exhaust system also needs liberating but don't expect an increase like you would receive on a 2 stroke which in some cases could be double the top speed. A good system which is stealthy in it's appearance is the Tecnigas Silent Pro . This offers low noise, improved top speed and freedom for the engine to rid itself of the gases.

The CDI is key to achieving more top speed, previously the only way to get past the electrical restriction was to cut part of the circuit on the CDI and re seal the unit. Now you can unplug the old unit without visiting a Piaggio specialist and plug the new one in it's place, the offer price is only £31.00. Although only an approximate figure we would expect you would see between 45 to 55mph with the components mentioned.

Honda PSi 125 and SH 125 i exhaust from Tecnigas 4Scoot

Tecnigas exhaust systems for scooters and mopeds are becoming increasingly more popular as people realise what we have been seeing for many years.
The new 4Scoot for the Honda SH 125, PS i 125 and @125 i adds to the range and keeps within the criteria you would be looking for when replacing a system on your maxi scooter.

The 4 Scoot stainless steel exhaust is a good choice for a few reasons, it offers a good performance increase over the standard unit. The longevity of the system is increased due to the materials used to make it and the price we are managing to offer this for is much lower than the original Honda scooter exhaust.
