hi i am doing 1 myself at the moment, you will need to remove, airbox, throttle boddies, radiator, cam cover, bit fidly to remove in the frame but it can be done, as the cam chain is fitted on the r/hand side of the engine there is no need for a complete engine stripdown, but you will need to take some carefull obsevations, once the rocker cover is removed you will see the 2x camshafts, you will need to remove the front r/hand engine cover this is the crankshaft pulsar cover, you will need a new gasket here, then you will observe the timing marks on the crankshaft t/= top dead centre, and the coresponding marks on both the inlet annd exhaust camshafts all these must be aligned make a drawing of this as it will have to go back together, in exact same position, with no room for errors,the exhaust cam has a pickup on it, make a special note of the position of this, you will need to undo all the camshaft cap bolts, this will alow removal of the cams to ease replacing your chain, if you wish you could also undo the cam sprocket bolts , these will require a loctite compound on refiting, you will then see the chain tensioner, this is on the rear right of the cylinder and it is held in with 2 bolts a new gasket comes with the cam tensioner if you buy the kit, a new gasket is also needed on the camshaft pulser this is located on the right hand side of the cylinder head, if you can acheive the disasembly without any problems, taking notes, making drawings, you will be able to reasemble it in reverse order, always use original parts, dont use gasket sealer , turn over your engine useing a spanner initialy to ensure corect valve timeing, a workshop manual is a must for your torque wrench settings it would also be usefull in guiding you throgh the afore mentioned job. warning do not atempt this job if you are in any doubt of your compentence to do it, paul
