    timing for srx250???

    Hello, I am new to this forum so hi to everyone. I recently rebuilt my srx250 with new piston,rings, cylinder,... the works. I just need to know how to time the cams with the crankshaft. Any help would be greatly appreciated. Thankyou.:slap:

    Valve clearance is In:0.05 - 0.10mm ex:0.12 - 0.17mm
    Ignition timing is 12 degrees BTDC

    Valve timing is the usual line up the marks stuff

    PM sent mate.

    Also, you should see a mark on the camshaft on the cog somewhere, It may be a arrow ect

    You have to be kidding that nobody knows how to time a 87 Yamaha srx 250 without a service manual?
