Once you add a big bore kit, that pump can't keep up. This high volume oil pump flows significantly more oil to critical engine components, reducing heat, wear, and the risk of catastrophic failure. Fits 1982 to present on all major Honda 50\/70 platforms — bolt-in replacement, no machining required. Highly recommended any time you're building past stock displacement.\u003c\/p\u003e\u003cdiv style=\"background: #f4f4f4; padding: 15px; margin: 20px 0; border-left: 4px solid #cc0000;\"\u003e\n\u003cstrong\u003e⚡ IN STOCK\u003c\/strong\u003e | \u003cstrong\u003eShips Fast\u003c\/strong\u003e\n\u003c\/div\u003e\u003ch3\u003eWhy Builders Choose This Oil Pump\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Volume Flow\u003c\/strong\u003e — Moves more oil per revolution than the stock pump, critical for modified engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBig Bore Compatible\u003c\/strong\u003e — Highly recommended when running any big bore kit to prevent oil starvation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBroad Fitment\u003c\/strong\u003e — Covers Honda Z50, CT70, XR50, CRF50, XR70, and CRF70 from 1982 to present\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt-In Replacement\u003c\/strong\u003e — Direct swap for the OEM pump, no special tools or machining needed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Engine Wear\u003c\/strong\u003e — Better lubrication means lower operating temps and longer engine life\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple Install Note\u003c\/strong\u003e — Requires a 2mm drill-out of the oiling outlet for proper flow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeace of Mind\u003c\/strong\u003e — Do not let a $30 pump be the reason a $300 big bore kit fails\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePerfect For\u003c\/h3\u003e\u003cp\u003e🔧 Big bore builds | 🏁 Race prepped pit bikes | 🛠️ Engine rebuilds | 🏍️ Trail and recreational riding | 👨‍🔧 DIY mechanics upgrading stock engines\u003c\/p\u003e\u003ch3\u003eComplete Kit Includes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e✓ High volume oil pump (1 unit)\u003c\/li\u003e\n\u003cli\u003e✓ Direct OEM replacement fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eHigh Volume Oil Pump\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eHonda 50\/70cc Engines\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e\u003cstrong\u003eInstall Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eDirect OEM Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e\u003cstrong\u003eRequired Modification\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e2mm drill-out of oiling outlet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e\u003cstrong\u003eRecommended Use\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eRequired with big bore kits\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e\u003cstrong\u003eYears\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e1982 to Present\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e\u003cstrong\u003eVendor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e50 Caliber Racing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eVehicle Fitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHonda Z50 (1982 and Newer)\u003c\/li\u003e\n\u003cli\u003eHonda CT70 (1982 and Newer)\u003c\/li\u003e\n\u003cli\u003eHonda XR50 (All Years)\u003c\/li\u003e\n\u003cli\u003eHonda CRF50 (All Years)\u003c\/li\u003e\n\u003cli\u003eHonda XR70 (All Years)\u003c\/li\u003e\n\u003cli\u003eHonda CRF70 (All Years)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhy Oil Starvation Kills Big Bore Engines\u003c\/h3\u003e\u003cp\u003eWhen you bore out a Honda 50\/70 engine, you are increasing displacement, compression, and heat output all at once. The stock oil pump was sized for the factory engine and simply cannot move enough volume to keep up with the added demand. Oil starvation shows up as excessive heat, premature piston wear, and eventually a seized engine. Swapping to a high volume pump is the cheapest insurance policy you can buy for a big bore build. The 2mm drill-out of the oiling outlet is a simple, one-time step that opens up full flow.\u003c\/p\u003e\u003cblockquote style=\"border-left: 4px solid #cc0000; padding-left: 15px; margin: 20px 0; font-style: italic;\"\u003eRan a 88cc big bore on my CRF50 for two seasons without this pump.
