    I'm changing out my front and rear sprockets along with a new 0-ring chain. The PO told me the chain was kinked (it is), since I'm replacing that I'm going to a 15/50 sprocket set also. I managed to score a 15t Sunstar front, 50t JT rear and an RK o-ring chain on Amazon for about $100 shipped.



    One thing different about the JT rear over the OEM is the indent in the sprocket and the indent faces outward. Now....the factory retaining clips overlap the indent on the JT sprocket. I'm going to go with slightly shorter new grade-8 bolts or washer out what is there. Question is, install them and the torque will make them conform to the indent?



    Am I correct on that? I searched the old and new site, but couldn't find a definitive answer.



    Pic is for reference, bolts aren't torqued down.

    That's what I do. Just line up one of the flats with the edge of the indent, then torque down. I don't bother the bend the other side of the safety tab up anymore, either.

    I installed my JT sprocket the other way, indent in.
    If you can't find it, grind it

    That's bass akward. Chain's out of alignment. Might not be real apparent, but it am.

    if it's off it's not off that much and if it's wrong then the dual sprocket guys are way off...but i think you're right...the tooth number should be facing out...i just liked the way the bolts and clips seated on the flat side better so it's staying that way

    I positioned and torqued mine the same way as Matty Moo and Lizrdbrth. No problems thus far.

    That is exactly what I did with the exception I didn't place a washer between the inner sprocket and hub. For sure both sprockets out of alignment but I had zero problems. Of course I kept the chain clean and well oiled all the time.

    i guess the thing i should have done is put washers on the inside equal to the indent in the sprocket...but i'm not too worried about it since the guys running the outside dual sprocket would be off much more than i would be and they aren't having any problems

    I emailed JT sprockets and this is what they said:



    "Bryan



    For the TW (I checked 2000 and 2009) the sprocket appears to mount with the flat side out.



    I have no experience with the TW so I am just going from the fiche on this. I would "eyeball" to check for parallel before finishing installation but flat side out should be correct.



    Regards,



    Richard"



    I figure that as long as your chain and sprockets are lined up, it doesn't really matter what side faces out.
    If you can't find it, grind it
