Sup everyone? I've been stalkin on the forums for a while but haven't actually posted until now. Well, I'm new to the scene and have been doin research on modifyin my F2 that I bought back in October. My question is regarding the site that I found that states the oem specs for sprockets and chain sizes:

I needed to know if the sprocket and chain sizes stated on this site is correct. That way, I would have a good idea as to what size sprocket and chain I would like to go for. Thanks in advance.

looks right, the only thing im unsure of is # of links..what are your plans? just regearing, extended swing arm, or what?

 

i was planning to upgrade the chain and sprockets since they appear to be worn out. i was thinking about going -1/+2 for the sprockets, but wasn't too sure if i wanted to make the front sprocket smaller. i originally thought that the front sprocket was 16. besides the increase in low end torque, would there be anything i should be aware if i were to decrease the size of the front sprocket from 15 to 14?

 

Don't change the gearing that much, unless you only plan on rallying that bike like a maniac through twisty turns. It will kill your milage, kill your top speed (although 100 tends to be fine) and make highway riding uncomfortable as 8k RPM for basic highway speed is full of vibrations.

I went two teeth up in the rear to put a bit more gusto on the bike, and bring my top speed down from 140+ mph to 135 or so mph. I can stomach that miniscule loss, and my bike is still comporable in take off to modern 600's due to this. They of course have a higher top end, but I rarely find even them pushing over 110mph, so really it's no big loss. Milage isn't a huge loss as I still get 33mpg in the city, and i mean in the dead of the city, tons of stop lights, short 3-4 mile drives far more than long ones, etc etc.

In short, stay at 15 in the front, go two up in the rear.

 

Thanks, jnicola, for your insight. Appreciate it.

 

i'll agree with the above. i used to be -1/+2 and i actually got worse mileage on the highway than in the city because the rpms were around 8k. i switched back to stock and my mileage increased dramatically but i kind of miss some of the get up and go so i will most likely switch to something in between pretty soon.

 

Thanks for the info, radman. What setup are you plannin to go with?
