By reducing the overall length, it improves throttle response and bottom-end acceleration, which is critical for clearing jumps out of tight corners on an 85cc bike.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How often should I repack my R-304?\u003c\/strong\u003e\u003cbr\u003eA: Because the R-304 is a performance-oriented silencer, the packing will break down faster than a stock unit. We recommend repacking every 15-20 hours of riding to ensure the bike maintains its performance and does not become excessively loud.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When repacking your silencer, don't just shove the packing in—wrap it tightly around the perforated core. If the packing is loose, it will vibrate and disintegrate in a matter of hours. A tightly wrapped, dense packing job is the secret to both a deeper, factory sound and consistent, crisp engine response.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/ktm-85-sx-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eKTM 85 SX Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/husqvarna-tc-85-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eHusqvarna TC85 Performance Parts\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/gas-gas-mc-85-performance-parts-and-accessories-moto-house-mx\"\u003eGas Gas MC 85 Performance Parts\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
