Would something like that fit my quad as it uses a clutch housing like this -thats your problem a 14 tooth front sprocket is 0_0 i whould go with something more reasonable like a 7 tooth front https://www.monsterscooterparts.com/clutch.html?gclid=Cj0KCQiA6IHwBRCJARIsALNjViWCtL_oJ8aZZ53f2PkLBQnMtbUJJmO091w1LeayIDc_iWK0jbPtj9caAtrgEALw_wcB
Thanks so because the 14 tooth front sprocket is pressed over the 6 tooth one on the front its classed as a 6 tooth?You have a 6 tooth 05T front and 54 rear and T8F 8mm chain. That sprocket is much bigger than a #25h 6 tooth so no problem, which gives you a final ratio of 9 to 1 a little to much for the weight you have. A 78 tooth rear would give you a 13 to 1 ratio, maybe a little low. A 6 to 72 is 12 to 1 which is what I would look for. Depends on how much top speed you want compared to low end torque. On my 110cc dirt bike I put a smaller front gear for more bottom end, and I can spin the rear tire out of the corners.
Thanks thats great. so hopefully a 11t front and 72t rear will get me around? 🙂That's where you confused me. That is a 15mm/ 6 spline trans shaft, not 6 tooth gear and the one you show looks like it has a #25h sprocket, the smallest gear for it is 11 tooth which would help you with more low end. Fine a #25 / 72 tooth rear sprocket if you want to go lower. The Repsol is an MT-A2 full fairing Cagillari Daytona, and your mini quad/ATV.
