    hmm headlights idk much bout them havent checked mine out but my brights suck i always ride with my dim lights on right now im having a oil leak issue and ive only had it like 3 weeks. it seems either oil leaking from the shiffter or it leaking from the front sprocket and onto the chain and getting thrown all over my back tire . it not alot to make me wreck but over 5 miles i noticed it get more and more oil on tire. if anyone knows anything bout that do chime in cuz i talked to dealer and they need know what leaking so they send a part and it either or both what i said earlier. and ive looked but cant 100percent tell

    35 tooth perfect from what ive heard unless your really light then could go to a 33

    I installed a 111 main , runs good but think needed to change needle jet as well

    as for the leak you sure its not just the drain plug leaking back ? auto parts stores sell oil drain bolt washers to stop the annoying drip thats common from pan drain bolts

    I was told that the Honda Rebel rear sprocket is the right fit from one of the other forum users. I ordered one today, so we'll see. Here's the link:

    I have bought many other parts from Old Bike Barn and have always been happy with them.

    I received it in today. It isn't even close. It has an 8-hole mount, while the 250rtc has a 6-hole. The chain size is different too.

    The one I bought fits the 250rtb bobber, but not my 250rtc sport bike.

    After buying the wrong sprocket, I did some research and I haven't been able to find anything that fits other than the aluminum one from China-Moto. I would pay the price if it was steel, but I can't pay that much for something that will only last 3000-5000 miles.

    u will need measurements , opening size , bolt size , bolt distance , ect

    but they will custom make it to your specs and mail it to ya for about 55 bucks


    if you call them they may already have the bike on file
