Rejuvenate your 998cc Rotax 1000 engine with the professional-grade L.A. Sleeve FL1291. Purpose-built to replace the original NiCaSil surface in monoblock cylinders, this chrome-moly alloy liner offers a rugged and boreable solution for high-capacity two-stroke restorations. It is fully compatible with R.A.V.E. exhaust and reed valve intake configurations, providing the structural integrity needed to handle the significant torque and heat of a liter-class machine.
The FL1291 features precisely profiled ports that guarantee exact synchronization with your engine’s OEM timing and airflow requirements. With a precision centerless ground outer diameter, the sleeve ensures a consistent, secure press-fit into the block. Designed for an 88.00mm standard bore, the interior is left with enough material for a final custom hone to your specific piston dimensions. Available now at Cheetah’s Powersports for riders who demand uncompromising top-end strength.
