Posted: Mon Feb 03, 2014 3:12 pm
Hi everyone,
As I am saving up for a home deposit it is time to unfortunately sell of a few of my toys.
I have for sale my precious 421cc RZ250 motor with the following features
-based on an RZ 250 bottom end
-very low hours (barely broken in, rings only just bedded in)
Bottom end
-4mm stroker crank (brand new, less than an hours use), 115mm rods
-billet barnet clutch with stainless inserts heavy duty springs, new barnet clutch plates and aftermarket pancake bearing kit to stop clutch rod seizures.
-bottom end has all new bearings
-inspected gearbox and only gears in perfect condition were used
-crank cases are industrial teflon coated so its very easy to keep clean
-light weight flywheel
-CNC twin pickup rotor and stator (two stroke shop)
-billet engine side covers
Top end
-CPI cub 421cc cylinder, 7 transfer port, triple exhaust port cylinder
-cylinder has a ceramic/teflon coating on the outside which is claimed to improve head disipation vs. oxidised aluminium
-Great cooling efficiency
-Billet head with interchangeable inserts
-Pistons are forged, with cermaic coated domes and dry film (lube) coated skirts
-Top end is in as new condition (rings only just bedded in)
Carbs
-2x Brand new Keihin PWK 35 (airstrikers?)
-vforce 3 reed cages
-aftermarket carb manifolds (to fit 35mm carbs)
-quick action throttle
-boost bottle (you can leave it on or take it off, makes no difference)
Exhaust
-The bike does come with a set of pipes, however they will need modifying to fit an RZ (they were designed for a TZR chassis).
Or you can just get a set of decent RZ pipes which will work fine with this cylinder
Ignition
Ignitech fully programmable Dual channel ignition is included in the sale if the asking price is met,
performance: somewhere in the area of 80-90hp at 10,500rpm
I am asking $4000 for the lot
I may consider separating items if I get a tempting offer(s)
for the right price I'd certainly consider selling just the top end.
In addition, I also have a professionally fabricated mounting kit to allow for this motor to be mounted into a TZR (2MA/1kt) chassis. and a high flow dual pass radiator which suits this set up also.
