Special Notes
DRI has spent 1000's of hours testing, doing R&D on 2-stroke port types and designs. There are no quick read manuals to explain the complexity of 2-Stroke porting.
Data must be gathered and recorded and analized, to help properly design cylinders that not only perform properly but give the reliability and consistancy expected from DRI
DRI PTR ported cylinders have won more Pro ATV Races and Pro ATV Championships than any other company in the world over the last 2 decades
All port work is 100% quaranteed
All PTR cylinders have port timing degreed in and all port dimensions are blued and scribed for MAXIMUM consistancy
PTR Porting is a labor service modification
All PTR porting is performed in house
All PTR ported cylinders and individually serial numbered. With data recorded in a DRI data file, for future referance
For Maximum performance and reliability with a PTR ported cylinder it is imperative the piston, rings and cylinder bore are kept good conditions.
Piston clearance should ALWAYS be kept under .005 of an inch
Quality Cylinder Boring and Proper Port Chamfuring is critical to the performance and reliability of your cylinder.
When these services are required for your engine, be sure that they are performed by DRI or a highly trained technician
DRI does not offer any big bore kits for Suzuki LT 500 due to reliability concerns
