Hmmmm, Im pretty sure your thinking of it backwards. If you size down in front then you raise your rpms, hense use more fuel and wind your bike out. But if you size up, you gain rpm and gain fuel eco. Unless every one has been lying to me. hahaeric said:Just curious.Why do you want to do that?Changing the spocket up by 1 tooth is changing
the final drive ratio up by around 7%.As that little engine is a high rev one with relatively
low torque it probably end up with less top speed not to mention higher fuel consuption.Unless
you are a slow driver of course. ???
Hi StockWall.Are we danceing on the same song?Are we talking about FRONT SPROCKET? You said size down raises RPM and again,size up gain RPM!?Did you want to say,size up lower RPM? Like I said if you are a slow driver than what you said is true.you LOWER the RPM n gain ECO.No doub.Trying to stay at high speed at 7% more load(through heavier final drive) though,requires a hand full of throttle to over come the same drag to a point that the same engine cant cope.When speed doubled,wind resistance raises by squere.Think I must call my long time science teacher.He must have tought me wrong.Ho hoStockWall said:Hmmmm, Im pretty sure your thinking of it backwards.

Yeah I agree, thats why I got such a small biketom_di said:I live near Fort Hood and all the "Look-at-me-I'm-a-big-tough-guy" cool guys have Busa's. Its the biggest... that makes it the best, right? Some guys just have to overcompensate.
Kids are amusing.crushedcamber said:Ha. Tonight i had to go to rockies to get some bolts for my bar ends... (utter disapointment) but thats another story. but while i was there a young ( maybe 13 ) kid was riding his bike around and was like "hey is that a yamaha?" ( to his credit i had my new tank bag covering the "kawasaki" on the tank ) but then i was like "no its a kawasaki" and he was like " oh i should've known... it says ninja, but i'm looking at hayabusa's) so i said "thats a lil bit big of a bike to start on buddy" and he said " well i have a 50cc honda at home " and at that point i was done talking to him... haha crazy kids.
But what is it about the busa that makes young kids want it? its huge, ugly, and way too damn heavy. i guess ill never understand.
I image that 18 would probably be too tall. I know that Darkhorse started a post a while back in reference to sprocket set up for racing. Search and you will find it. He is looking for speed and you have to love him for his noble quest to go as fast as possible. Racerboy also has been doing some R&D for commuting on the highway it a quest to save fuel. Search for 16 tooth and you will find it. I also commute everyday 20 miles 1 way as fast the bike will allow. I'm a hybrid. I would like to get better mpg but its not that big of deal because I'll probably be dead soon and the gas in the tank would just go to waste or burn my flesh in a fiery crash.eric said:Yes,that's the theory in mathematic tern.
If it's always that simple why dont we all put on a 18 teeth sprocket
and go chase a BUSA. ;D
