This batch of kits from airsal did not have the cylinder fins cut. Therefore many intakes will not fit without cutting the fins. Because of this small imperfection, we are dropping the price. Still a great kit if you don't mind cutting the upper cylinder fins!
Bringing one of the first new kits to enter the scene in a long time, Airsal steps its game up and delivers a bold new design for the A55 model Tomos. This 44mm/70cc bore kit uses a four-transfer port map with a giant single exhaust port, very similar to a 45mm / 75cc Gilardoni.
This kit is meant for a Tomos A55, but it also will bolt right up to a Puch engine. Unlike the Metrakit and Gilardoni 45mm kits, this Airsal does not require case-boring to fit to the engine. It is still a magnum style cylinder though, and will require an exhaust built with a angled mount in mind, like the Homeot 8p.
We've successfully used a Polini 19mm intake meant for Minarelli/Garelli mopeds on this kit, we just had to cut out two of the fins off of the head to mount a spigot style PHBG Dellorto Carburetor.
A55 owners will be able to bolt up their stock equiptment, although it is not recommended. If you are getting this kit, you will want to get the carb upgrade kit at least, a performance exhaust, and maybe some new sprockets. This is the best kit out there for Tomos mopeds.
