Service Schedule for 1998 Honda Firestorm. At what mileage do valve clearances, cam chains etc need checking??

chains are not repairable only replace with new ! remove camshaft etc then cylinder head , then barrel and with the side cover etc removed then replace the chain ! tdc the piston when barrel back on feeding the chain up , fit head then fit cam with all valves closed and should line up to a mark on cam cog , fit chain then bolt the cam down , rotate the engine several times back to tdc and check valve clearences and refit all parts and change the oil !

Manufacturer recomeds tensioner @ 40k but please change them at 35k. My rear tensioner failed @ 40150 ks and two bent valves, valve stem seals, head gasket + the two 50$ tensioners + labour, i was back on the road.
as for the servicing i personally have been doing 5k oil and 10k oil and filter change. As long as the service intervals are with in six months apart i dont think you wil have a problem. If you dont do many k's change your oil at least once every six months-oil is cheap.

hi as this runs on an automatic tensioner arangment there is no set time for checking, if the chain becomes noisy or you suspect early failure then this would be a good time,

Get your valve clearances checked & adjusted, otherwise its a burnt-out or bend valve or somehow the ignition timing has moved (unlikely)

Good Luck
Hope this helps.

Some VTR1000's had a problem with the cam chain tensioner on the front cylinder. If this is left the chain can become so loose it skips a few teeth on the cam sprocket and bends the valves. If you can locate the tensioner, remove the centre screw with sealing washer from it, insert a small flat blade screwdriver in and run the engine. you will feel the screwdriver shake about if the tensioner has gone.

can be many things buddy stripe the top end and inspect it could be valves gone gasket cam shaft rocker arms etc only way to find out is too strip it your self and get back to me

Check the valve lash (clearances). If not enough clearance, the valve(s) could be not fully seating which would create the problem you have described.
