Our equally weighted drop-in ~820cc pistons (no crank rebalancing needed) for our 4V head conversion for your ’09 to current V7C-S. Pricing is for one set of pistons including all rings, wrist pins, custom metal larger bore head and OEM base gaskets. We HIGHLY recommend installation in-house here at GT (ship us your motor or bike) or contact us for a turn key bike. Power graphs for comparison shown HERE. If the pistons are not in stock, typical lead time is ~12 weeks.
Our full GT conversion kit includes retro-fitted 4V heads with all new modernized parts (valves, springs, seats and seals) and performance flow-ported intake and exhaust tracts, along with new push-rods and related to make it a near drop in swap. Have your cylinders bored and re-nikasiled yourself, or we are offering an exchange with a $1k core deposit – Overseas orders require you to send us your cylinders in advance. You will need to modify your stock header inlets to mate to the 4V heads, or purchase our GT-Rx® Headers or full system. Some light machining needed for the intake manifolds and pushrod cylinder clearancing (DIY with a grinding tool or dremel). GT Fueling revisions MANDATORY – see our ReFlash Tool – which will be included in the full kit with 4V heads, and cylinders with exchange. Approximate cost is ~$3500 parts only – Contact us for details.
