91ZXR400Lカスタム車両 NEN471cc+JB製FCR33 5.5リアホイール WPリアショック BEETマフラー コワースBS 純正シングルシート スペアパーツ有

This is a customized 1991 Kawasaki ZXR400L (ZX400L). The engine has been swapped for one with mileage similar to the odometer reading, then rebuilt top-end by NEN in Yashio with their original piston kit, bringing displacement to 471cc. Since the rebuild it has covered roughly 2,000km of break-in mileage; the seller states current output is about 72hp with potential for around 80hp if tuned further. Other modifications include: fully adjustable front forks from the M-model (rebuilt ~3,000km ago), a JB-handled FCR33 carburetor set (blue funnels, normal insulator type, ZX9R fuel pump of unknown effect), a BEET steel exhaust base modified with an up-swept, lengthened design and an unidentified stainless/titanium silencer, a WP two-way fully adjustable rear shock (likely a custom unit, purchased used ~3,000km ago), a black-painted swingarm from the same year with rebuilt bearings, a black-painted ZX6R OEM 5.5x17 rear wheel (bearings swapped for fitment), Dunlop Q5 tires (front 120/70, rear 180/55, under 2,000km), shimmed rear shock mount raising ride height about 5mm, an M-model FRP single seat and seat rail (single-seat configuration, with scuffs and cracks), Coerce rearset steps, an aftermarket oil catch tank, cut rear fender, aftermarket brake pads, and custom-fabricated brackets. Chain is an RK BL520RXW and sprockets are Sunstar, both replaced about 3,000km ago. Spare parts included: the original engine (removed, sold as parts only, not running), the stock carburetor, stock seat cowl, tandem seat, tandem steps, and seat rail. Vehicle inspection (shaken) is currently expired but the seller will obtain it before handover; title, transfer certificate, and power of attorney will be provided.
Seller notes general wear and small scratches consistent with age (fading, minor scuffs), plus scuffs and cracks on the FRP seat, and a weak battery from infrequent use.
Shipping: The seller prefers the buyer arrange direct pickup by trailer due to the included spare parts. A shipping fee figure appears in the listing but is truncated/unclear in the source text, so it should be confirmed with the seller before quoting freight.
