necesito datos cr 250 año 2007

Hola compañeros;

necesito un alma caritativa que tenga una cr del año 07 y me pase escaneado unas hojas ya que de momento no tengo el manual.

1. La hoja donde viene las distintas carburaciones según altitud (osea chicles y pin de aguja).

2. Los desarrolos que trae de serie, o mejor la ficha técnica completa.

3. El aceite que lleva en las horquillas y las durezas de los muelles (blando, estandar y duro).

Por favor me lo envía al siguiente mail [email protected]

Y si alguien me lo presta lo fotocopio y se lo devuelvo en un periquete y le invito a unas cañas (si es de madrid sino me pilla un poco lejos). No me importa que sea en ingles.

Gracias por anticipado,

Con las carburaciones no puedo ayudarte, pero puedes ver los muelles que lleva de serie aqui:

http://www.mx-tech.com/?id=bike_informa ... ght_type=1

Horquilla 0,44 kg/mm

Amortiguador 5,0 kg/mm

Tambien te calcula los que necesitas segun la especialidad que practiques y tu peso. Pincha en "get spring rate".

El aceite es el mismo que en nuestras CRF, el showa "noseque" (ahora mismo no lo recuerdo) pero es el que usa siempre Honda. Si lo cambias te aconsejo que le pongas un sae 2,5 para ganar suavidad, aunque no se que te voy a decir que no sepas ya.

Los desarrollos los puedes mirar en la corona que suele venir el numero de dientes, o si no, no tardas mas de 1 minuto en contarlos. Marca uno con un rotulador y cuenta desde ahi.

Prueba primero bien la moto segun viene y luego ya tendras mas claro que cambiar segun tus gustos.

Saludos.

PD: no nos has puesto fotos de tu maquina.

De momento, puedo avanzarte que tiene una carburación bastante inestable la 2007!! :? .........

Quizás no es lo que buscas peró, este manual no tiene desperdicio, es el manual de taller, no el de usuario.......... :wink:

dime si tienes fax y el domingo por la tarde te lo envio!

Gracias a todos. Migue el nº de fax es 91 8873660 att. Javier Bellido

Gracias de nuevo y a disfrutar de las maquinas.

por cierto Gus jodío lo del desarrollo es porque es una cre y me viene con un 14/47 que me parece en principio muy largo aunque en la pequeña prueba del día 1 me fue muy bien. De momento y a pesar de ser de letras (derecho) lo de contar por lo menos hasta 100 no se me ha olvidado (que jodío el profe).

por cierto, si Papa Noel ha sido así, no me imagino los reyes magos....

Gracias salmi el manual cojonudo es lo que buscaba pero me mosquea un poco que ponga CR 02-03 y aunque desde entonces no es que haya cambiado mucho espero al domingo y que migue me mande el del 07, lo escaneo y se lo paso a quien quiera.

Un saludo,

El Inglés y yo estamos peleados pero estos serían los cambios..... :wink:

2002

NEW FOR 2002:

* All-new case-reed engine features a redesigned air intake tract and an electronically controlled RC-type exhaust valve.

* All-new third-generation twin-spar aluminum frame, a narrower cross section and a 1.1-pound weight reduction.

* Redesigned rear brake system reduces weight 11.8 ounces.

* Aluminum spoke nipples on front and rear wheels and a new rear wheel and hub design contribute to unsprung weight reductions of 3.5 and 15.9 ounces, respectively.

* Refined rider ergonomics.

ENGINE:

* Liquid-cooled two-stroke single-cylinder engine with 66.4mm x 72mm bore and stroke and 8.5:1 compression ratio.

* Air intake boot is reshaped and boot volume is increased 65cc to provide a 7 percent increase in airflow capacity, contributing to improved performance in the mid-and upper-rpm ranges.

* Crankcase reed induction with two-stage carbon fiber four-petal reed valve.

* RC-style exhaust valve features an NSR® road racing-inspired rotary flap design with electronic control. The electronic control module uses engine rpm to calculate exhaust valve position and signal a DC servo motor to adjust the RC valve.

* New Exhaust header and expansion chamber.

* A 16-bit CPU incorporates both the DC capacitive discharge ignition (CDI) and exhaust valve servo control.

* Clutch damper design improves rear suspension feel and action while accelerating over bumps.

* Lightweight magnesium clutch cover reduces weight 7.8 ounces.

* Five-speed close-ratio transmission features a thicker fourth gear.

CHASSIS / SUSPENSION:

* All-new third-generation twin-spar aluminum frame has taller swingarm pivot plates and thinner frame spars to create a narrower overall frame cross-section. Together with a new, lower subframe assembly, rider comfort and maneuverability are improved and frame weight is reduced 10.6 ounces.

* Semi-double-cradle design features a single large-diameter, tapered downtube. Two rugged box-section rails attach to the base of the downtube and support the engine. A forged aluminum steering head provides a compact and extremely durable mount for the frame spars and engine downtube.

* Swingarm features a dual-axis, double-taper design with a large cast aluminum cross-member. Swingarm casting walls are 0.5mm thinner to decrease weight by 7 ounces, yet overall rigidity is increased by 20 percent.

* Front and rear wheels feature HRC© works-type lightweight aluminum spoke nipples. Front wheel unsprung weight is reduced by 3.5 ounces. Together with a new rear wheel, hub and spoke design, rear wheel unsprung weight is reduced 15.9 ounces.

* Lightweight, 47mm inverted Showa® twin-chamber cartridge fork with aluminum dampers is 12.3 ounces lighter than the previous design and features 12.4 inches of travel, 16-position rebound damping adjustability and 16-position compression damping adjustability. Inner surfaces of front fork outer tubes and rear damper case are molybdenum-coated for smooth, low-friction operation.

* Pro-Link® single-shock rear suspension features a fully adjustable Showa rear damper and 12.6 inches of wheel travel, separate low-speed (13 positions) and high-speed (3.5 turns) compression damping adjusters and 17-position rebound damping.

* New HRC works-type rear brake system now integrates the rear master cylinder and fluid reservoir, eliminating the rear master cylinder reservoir and hose. Together with a smaller caliper and smaller-diameter rear brake piston, overall system weight is reduced by 11.8 ounces and serviceability is improved.

* Rear disc swept area is increased 14 percent to provide optimum braking control.

ADDITIONAL FEATURES:

* New frame allows sidecovers to have larger air intake ducts, contributing to a significant airflow increase in the mid- and upper-rpm ranges.

* Rider ergonomics are optimized by raising the handlebar 2.5mm and moving it 3mm closer to the rider, raising the seat 5mm and raising the footpegs 10mm.

* Seat cushion uses multi-density foam construction.

* Brake lever and shift pedal are redesigned to fit the improved riding position. Brake pedal features a revised ratio to match new rear brake master cylinder design.

* New chain guide material offers improved wear resistance and durability is increased 300 percent. Chain roller now features a tough, double-sealed bearing.

Coño y el 07.

Bueno examinando por encima el tema el desarrollo es de 13/48 desde el 02 (no creo que lo cambiaran justo en el 07 joder).

En el 05 fue el gran cambio de nuevo con distribuciones de cilindro, válvula etc etc mientras que en el 06 solo se retoco la valvula.

por lo que me temo que la 07 es como la 06 con distintos adhesivos.

me he bajado el manual del que pasabas el link. Cojonudo ya le he echado un gran ojillo y me viene muy bien.

Hoy he podido ojear el manual de una 125 del 07 para ver las cantidades de aceite de las horquillas y me ha sorpendido que por primera vez viene expresado por la camara a dejar y no por los cc aunque las tolerancias que ponía me parecen muy muy grandes.

Estandard 71mm, máximo 37mm, mínimo 113mm. eso a mi parecer son muchos cc pero lo comprobaré y compararé con el manual que me he descargado y con lo que me pase migue el domingo.

Gracias de nuevo Salmi, si necesitas cualquier traducción me lo dices y te la paso.

migue confío en ti para el domingo.

Un saludo,

Esta es la 2006, cualquier diferencia con la tuya, es pura estética!!! :lol: ......

Ya iras explicando eso de las horquillas porque ese es un asunto pendiente que tengo!!!

Saludos,

http://www.transworldmotocross.com/mx/p ... 62,00.html

En las horquillas lo que normalmente hago es ponerle un aceite de calidad önhlis sae 5 y en una cantidad intermedia entre el estandar y el mínimo y en el cartucho 150cc aunque en la 07 parece que viene 196cc ya que yo ahora peso 90 pero lo normal es que pese 80kg y me gustan las supensiones un pelo firmes. Y parto de una posición intermedia de clicks tanto en compresión como en extensión, y normalmente acabo dejandolos entre la posición media y la mínima Soft.

El sag del amortiguador trasero lo dejo en 100mm.

Un saludo,

Buenas, aquí tienes los datos oficiales :wink: .

Revisaré como llevo la amortiguación!! aunque cuando la compré ya estaban preparadas por M. Romaguera, van muy finas pero últimamente me dí cuenta de que el SAG que llevaba era para alguien bajito y de poco peso (143mm), ya lo tengo solucionado.
