BILLETRON 38mm 2-Stroke Carburettor by Lectron Fuel Systems

* Anodised colours Red/Blue/Orange/Black have a 14 day lead-time from time of order.

Lectron Fuel Systems has taken years of rider feedback on their wildly popular 38mm H-Series Carburettors to develop the all new Billetron 38mm 2-Stroke Carburettors. The new billet aluminium construction reduces the weight of the carburettor which adds to the impact resistance and visual appeal of the carburettor. The redesigned bell and bore, along with the H-Style slide, give a faster response and better bottom end hit. The choke and idle/power jet screws are now more accessible allowing for quick tuning on the track or trail. Shorter than the H-Series, in both length and height, this carburettor fits more like an OEM carburettor. It also uses the stock throttle and cable making installation easier than ever. 

With both increased performance and an improved user experience, the Billetron 38mm is a game changer...
