take your time, get a good set of allen sockets for the rear sprocket and a impact screw driver, (the kind you hit with a hammer) to break them loose or they will strip, also if you are handy with a propane torch it wouldn't hurt to heat them up a tad to soften the loctite from the factory. the front is no biggie remove frt sprocket cover and remove the bolts or clip holding the frt sprocket on. check the seal behind the sprocket while you have it off and make sure its not leaking everything should look nice and dry, take your time and clean up everything while you have it apart. adj chain tension and lube it after a very short ride to heat the chain up. and dont reuse the cotter pin that holds the rear axle nut from backing out, matter of fact dont ever reuse cotter pins. that would be a better habit to have! get the torque specs and torque all bolts etc to correct torque specs, if you don't have one borrow one, you don't want to strip,break or have these back out on you, also check your wheel bearings while you have it all apart, and it goes without saying but i assume you guys are also changing out the chain with the sprockets? unless your scoot has got very low miles you always want to change out them all in a set.

Allen sockets for the rear sprocket??? Are you talking about the rear sprocket on the rc? All you need is a ratchet and the right size socket to get it off. I'm looking at my rear axle and there's no place for a cotter pin???

i'm generalizing as most rear sprockets on bikes have a allen bolt holding on the sprocket. and if there isn't a spot for a cotter pin on the rear axle nut it would be a good idea to drill i small hole through the bola and axle and saftey wire it. do a google on it to get a better idea of how its done. i have a bad habit of saftey wiring everything, i have yet to do it to my current bike though?

Do you even own a 51?

The only reason to safety wire your bike is if its a track bike only.

i work at the largest dealership in the ky. area as lead service tech, and you do know why they safety wire track bikes? so bolts don't back off and people have accidents. kinda a good idea for the street too, and no i do not own a rc51, i do however own a fz1, crf450, 94 ninja 600r and soon a rc51 but that really isn't relivent to my statement i made, you are presuming that only rc51 owners know how to work on them or give advice on them. i was simply trying to give him some pointers to go by whether he chooses to follow them or not his choice, i have changed out approx 20ish sets this year how many have you changed out? not to get a war started or to insult you in any way but i am just trying to help a guy, and to set the record clear i have 6 certifications from all the major manufactures, kawi,suzki,honds, etc. so with my advice does come a little crediblity

I don't care if your last name is Honda. Your resume means nothing to me. I'm not saying only 51 owners can work on 51's but the info you are giving is wrong which leaves me to believe that the 20ish sets you've changed out this year not one of them was for a 51? Since the 1 I did change was on a 51 I think my knowledge about this part of the bike is alittle greater than yours. And just to straighten you out again the object in question is a nut not a bolt. If things are torqued to correct specs then nothing should back off. These safety measures you speak of are not necessary on "street bikes" or it would be done from the factory.

Pushover,
Don't forget the speedohealer, it will repair the speedometer discrepancy you most certainly have now. I think mine with the 15/42 sprockets read almost
12mph LOWER than actual. I verified the error by mounting my Garmin and reading my speed at 55mph satellite, or actual, my indicated speed was 42!
Totally annoying! Enjoy the gear change, it's the only way to have an RC on the street. Missing mine big, the roads are still crap, will probably take the Enduro out this weekend.

John
