    1997 cr250r rear shock help

    Ask the seller to measure the length between moutning bolts and mouting bolt hole sizes. If they match then the other shock fits(check the gas reservoir location for fitment too, to make sure that there are no issues with clearance between frame etc). The best way is if you happen to find a...

    yx 150 ugrade to yx 160 possible?

    1. The extra stroke is compensated by shorter con rod and because of that cylinders are the same height. Well I have seen an yx160 with 5-6 base gaskets as a spacer since somebidy forgot to use cylinder head dowels and the valves were hitting the piston, too simple fix, but those hack jobs never...

    yx 150 ugrade to yx 160 possible?

    All yx150/160 and z1ˇ55 z160ho cylinders interchange. And there are cranks with oil slinger and without oil slinger for both yx150 and yx160. Z160HO crank does not fit yx160 without z160ho clutch cover...

    yx 150 ugrade to yx 160 possible?

    Yes the yx150 and yx160 cranks are interchangeable ie the only difference between yx150/160 is the crank (so no need to bore the cases), everything else is the same... Z155/Z160HO YX150/160 cylinders are intercheangeable too and heads fit, but there are exhaust port mount differences and you...

    125cc pitbike cutout

    First of all check for proper ground. I have had numerous issues when using the stock stator gorund, now I always use frame ground to be sure :D .

    125cc lifan cam chain tentioner

    Seems like either the tensioner is faulty or you are low on oil since the tensioner works with hydraulics basically since oil can´t be compressed.

    ohalee axle bolt

    No, m10 m12 m14 m16 are standard sizes. Yours seems to be m14. And those pitbikes are in metric sizes. I would advise you to buy m14 12.9 hex head bolt and use washers on either sides. The standard lengths with thread + straight part are 220mm and 280mm (the threaded part is 40mm). But m14...

    Whats oil for my lifan 140cc engine?

    Any mineral diesel engine oil will do also. Mineral, because it makes the clutch rubner dampeners last longer. And cheap disel engine oil has rarely got any friction modifiers in it, that cause problems with wet clutches.

    Mikkh's WPB 125 CRF 70 framed build

    The rear brake still to finish and the seat foam needs replacing. What would be good readily available material for it?

    Re gasing rear shock

    Maybe your loval tire shop, who fills car tires with nitrogen can help you. If you recharge the shock you should replace the oil too. I use atf vi for my rear shocks, because the rrar shock oil gels up in -30C :D.

    Gpx 125cc problems

    Larger size thread can be made to fit larger thread spark plug. When I get home I will specify the larger thread spark plug.

    Mikkh's WPB 125 CRF 70 framed build

    Got the valves and piston. Replaced them and the bike has lots of compression. It is quite rideable, but I need to change the seat foam to better one. And the swingarm bushings are still worn (sideways). The r6 rear shock is just excellent. I will take few pics of the bike in a few days.

    Mikkh's WPB 125 CRF 70 framed build

    Little bit of updates. Ordered the piston and new valves etc few weeks ago. Should get them soon. The bike rides good, expect that I bent the front whee while landing on a tree root in the forest, the swingarm needs new bushings to be machined on a lathe and the upper shock mount on the frame is...
