Hey I have a Suzuki Across 99 GSX250F, just trying to figure out which parts to buy. Are all the sprockets pretty much standard? The manual states a 49/13 ratio, can I just find any old 49T sprocket and fit it on? I.e (http://www.ebay.com.au/itm/JT-Sproc...ccessories&hash=item3377a5cd1f#ht_1383wt_1097) Similarly the chain states DID520V or RK520 with 110 links. (http://www.ebay.com.au/itm/RK-M-520...rcycles_Parts_Accessories&hash=item519fca4cc2) will this do the job? Also - if I buy the 110 link chain, will I still need a cutting tool?
