-1 sprocket installation (07' GSX-R750)

There are a lot of questions about how to install a new front sprocket on the newer bikes. Here's a how-to. I like to mark my clutch lever and my gear-shift lever so I know where to put them. http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00807.jpg Then you can remove the gear shift lever by removing the bolt and slipping it off. http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00809.jpg Then screw the adjuster all the way in so you have enough slack in the clutch cable. http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00810.jpg Unbolt the clutch lever and pull it off. http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00811.jpg Remove the bolt that holds the speed sensor in http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00812.jpg Then remove it http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00813.jpg Remove the 5 bolts holding the sprocket cover on. Leave the bolts in for now http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00814.jpg Mark a cardboard box and mark where the bolts go. http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00816.jpg Pull the cover straight out and hang it from the rear peg http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00817.jpg Flatten the cotter pin and pull it out. http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00818.jpg

Loosen the nut enough to move the wheel http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00819.jpg Loosen the nuts in front of the adjusters http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00820.jpg Screw them all the way in and push the wheel forward http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00821.jpg Slip the chain off of the rear sprocket http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00822.jpg Remove the speed sensor wheel from the front sprocket http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00823.jpg Remove and set aside http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00824.jpg Loosen the front sprocket http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00825.jpg Remove the washer and set it aside. http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00826.jpg Slip the chain loose around the sprocket and remove it. http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00827.jpg Here is the old sprocket and the new http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00828.jpg

I like to measure the two to make sure they are the same width http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00829.jpg Work the new sprocket in http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00830.jpg Reinstall the washer http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00831.jpg Set your torque wrench to 60 pounds http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00832.jpg Torque the nut to 60 pounds and then to final torque. My manual said 88. http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00833.jpg Slip the chain back over the rear sprocket http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00835.jpg Readjust the chain tension. I use a set of calipers to make sure the alignment is right. http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00836.jpg Tighten the nut and reinstall a new cotter pin. http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00837.jpg Check the chain tension while you sit on it. A little loose is better than tight. http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00838.jpg http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00839.jpg

Reinstall the speed sensor wheel http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00840.jpg Reinstall the cover, torque the bolts in a circle, then reinstall the clutch lever http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00841.jpg Reinstall the speed sensor http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00842.jpg Reinstall the shift lever making sure to realign. Heres the finished product http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00843.jpg Adjust the lever until you can barely fit a dime between the lever and the bracket. Make sure the clutch works. http://i152.photobucket.com/albums/s171/jhall0011/Sprocket%20Installation/DSC00844.jpg That's it. Double check everything, including the clutch, and your done.

Can you move this into the FAQ section? Thanks.

looks good. i couldnt get the bolt on the front sprocket off though. it was on so tight that the whole bike would move while turning the wrench

If you put it in 6th and hold the rear brake, it won't turn. I never really thought of that. It would have been hard for me to hold the brake though when I was the only one doing it. I guess I could have wire tied it down or something. Where theres a will theres a way.

Holy good write up batman. NICE JOB:thumbup:

also i was told the speed sensor bolts are known for backing out and destroying the speed sensor so use some lock tight, i just did my 600 sometimes i miss my highway gear but the new power is very nice

So with the -1 adjustment made, does the 750 seem like a wheelie monster now? Or does it just have more drive out of the corners?

So with the -1 adjustment made, does the 750 seem like a wheelie monster now? Or does it just have more drive out of the corners? Yeah it makes a huge difference and it's not too anoying on long rides. Def wheelies easy.

damn nice write up man. I will be looking for this one again in the near future.

Thanks for postin that....well done.....

One more thing on this...... Isnt the actual nut on the front sprocket reverse thread? I did a buddies Ninja ( which was ALOT LESS involved) a while back and was having a hell of a time getting it off until I accidently hit the reverse trigger on the impact and it spun right off.

No. On Gixxers it is right hand thread.

This is my first post... I've owned several bikes over the years, but always wanted a GSXR 750. I finally have one... got it used, but light mileage. Bike is a 2002 with 4,100 miles. On my drive home noticed the RPM was a little high... Like 4,500 - 5,000 at 60 mph... and climbs accordingly. I also note that the speedo is 10 miles off says I'm going 10 MPH slower than I am at 60 MPH. I am taking the bike into the dealer for an oil change and what not and would like to know what to ask for in getting that adjusted. Any help? I would like the RPM back to a reasonable level on the highway, as I'll be using the bikes for highway rides a lot. Any recommendations? Thanks Jon

Thanks Jon You would need a SpeedoHealer to calibrate your speedometer & you can take of your sprocket cover up front to see if you have an aftermarket or oem sprocket on it & also count the teeth on the rear one to figure that out .
