I ended up with the 48 tooth rear sprocket and it's working great. The one problem I am having is gear noise between about 45-67mph, it goes away at higher speeds. Is this normal when changing the gearing. My chain adjustment is correct and I don't really see anything out of the ordinary. Let me know what you guys think


thanks

If you don't want to spend more $ I would just use the -1 on the counter shaft and leave the back one stock. I have -1/+2 on my F3 and as Havoc said, it effects the engine breaking and power up in corners.
good luck.

Went out and tested the bike against a mates ZX10 and anothers R1 just before running out of road my speedo was reading 173 mph with 2k rpms left before redline and both my mates bikes which have standed sprocket set up were reading 166 mph wtf i seem to have gained topend aswell when i went down 2 teeth on the front sprocket. before the mod i was only reaching 155mph on my speedo.

 

streetfighter88 your speedo is off from changing the gearing. my bike shows 90 when i am only going 80. gets worse the higher i go in speed.

 

Yer i know my speedos off thats why i ran it against my mates bikes hew have standed gearing, i ran it against my mates F2 lastnight aswell and he claimed he was toped out when i just flew past him were as last time i raced him i was literaly only about a foot ahead of him.
