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.
