    im pretty sure its from oil either leaking past seals and burning or from valves sticking open a little and letting oil past.


    or could be oil sepping past the rings . what did they supposedly fix???

    Usually the oil control ring is stuck inside the piston groove. Sometimes it's maintenance interval is up and the ring simply lost it's spring tension, sometimes it's an overheating/lean condition caused the rings to go.

    Except for a timing chain, an oil control ring, and valves instead of ports the grizz is just like the blaster. Purchase a service manual and tear into it!

    well, there is somthing wrong with it, u gotta find out what before you can expect it to be reliable, i have ridden grizz 600's that are really reliable, u just need to have some patience and find the problem, riding it like it is is prolly gonna cause more problems

    It obviously has some problems but rest assured that it's nothing a little elbow grease and a service manual can't solve...

    Start with the basic trouble shooting. Pull the fuel line off the side of the carburetor and see if the petcock is running fuel. Pull the drain screw out of the bottom of the carb and see if the float is letting fuel by. Pull the carburetor and clean the main jet and pilot circuit to make sure the carb isn't stopped up.

    Once you've done that you know it's not a fuel problem you can look at other problems. Electrical problems or a compression issue.

    spark plug, air filter, oil, oil filter, steering column, pittman arm, tie rods, front brakes, back brakes, and some more small stuff.


    he said it was smoking because there was not enough oil. he had his buddy who lives up the street from me drop the bike off. when i got back from taking my brother to the airport the grizzly was sitting in my driveway. it fired right up but was knocking bad and smoking like crazy. the smoke is blue and smells bad

    yeah. iv'e already spent $1200 on everything that this POS needed. and i'm not putting another penny into it.



    guys, one life tip: when your about to buy something big dont trust your impulses.


    i still am dying to figure out how to adjust valves. if this fixes this thing then i'll be jumping as high as the moon

    Alright, here goes.

    There are three inspection plates, one on the front of the engine over the exhaust pipe and two on the back over the intake manifold. The exhaust cover is held on by two bolts, the intake covers are screwed into the valve cover.

    You will need a screwdriver, a wrench, and a set of bent tip feeler gauges. KD tools makes a set of valve tappet feeler gauges BUT the smallest size is .008" which is too large for setting manual tappet valves. Usually the setting is like .004" on the intake and .005" on the exhaust.

    Take the spark plug boot off and ground it out, remove all of the inspection covers and roll the engine over until the camshaft is tensioning the other set of rocker arms. The service manual will have a certain timing point you'll need to line up on the flywheel but all you have to do is make sure that while you're adjusting the exhaust valves, the intake valves are actuated. Insert the feeler gauges and see how it goes in. The feeler gauge should slide in with light resistance. Nothing more and nothing less. If there is more slop in the tappet than that, loosen the jamnut and turn it with a screwdriver. Once you have the "setpoint" for the screwdriver pull out the feeler gauge and hold the position with the screwdriver while tightening the jamnut with the wrench.

    A light tapping would be valves, this could also be causing your smoking problem if it isn't very heavy smoke. Also I would not go to that shop anymore, I would take it somewhere else, not to often have I seen anything smoke when the oil was low, and if it was still doing it after it was there he must not have put enough oil in, haha. I alwasy though blue smoke was anti-freeze/coolant, but it has a sweet smell to it.
