This cylinder kit comes to us from Italy and its performance stands up well to the legacy of italian racing. It uses the two petal reed valve intake from the Tomos A35 with a six-port transfer design on a chrome-sleeved aluminum cylinder. It's a great bolt on performance upgrade for a A35 Tomos, and does not demand and case port matching.
Like any performace upgrade, this kit will work better with its paired performance upgrades, like a matching carburetor and expansion chamber pipe. This kit is designed around the A35 cylinder, but with a little ingenuity, can be made to adapt to any tomos engine or model.
