05 GSXR 750 Speedometer Reads 0

If it's 54 outside and the fan is not running because the cold air is passing through the radiator and the coolant is doing it's job. Then you come up on a red light and basically all of the sudden that 54 degree wind chill has somewhat stopped (because 54 degrees outside and going 50 mile per hour creates quite a wind chill) the engine will heat up, cause the thermostat to open allowing the fluid to flow through the system. Now the fan kicks in at 220 degrees and begins to cool everything back down or you start riding and the wind cools it back down again...........I hope this helps a little. My bike heats up quickly too especially after riding for awhile and then stopping at a red light. I flush my coolant system yearly before the winter. It's generally recommended every 2 years.Ref: https://www.gixxer.com/forums/80-06-07-gsx-r600-750/294175-rapid-heating-idle.html

14 - 41 = 2.93 ratio
15 - 46 = 3.06 ratio..
6-7 links.. you need to move the axle all the way forward when installing a new chain... (it will stretch!) moving the axle all the way forward gives you plenty of adjustment later!!

I HAVE A 2005 GSXR 750 AND WHEN IM AT HIGH RPM THE BIKE SHUTS OFF. DOES THIS HAVE ANYTHING TO DO WITH THE FI CODE BLINKING? BUT THERE ARE DAYS WHEN IT RIDES FINE....WIERD

The original chain was DID50V4 , 110 links using 17 tooth sprocket on the front and a 42 tooth on the rear, remember to check the sprockets are the correct size before ordering a new chain

Hello,
The speedometer sensor is located in the countershaft sprocket cover. This is the cover at the lower left rear of the engine. If you are having speedometer problems, be sure and check the speedometer rotor that is on the end of the countershaft. They have come loose and caused problems.

you need to replace font and rear sprockets and chain,buy good quaulity o ring chain

pull front sprocket gear , buffer installs behind gear

The stock rear sprocket is 41 tooth. The stock front sprocket is 15 tooth. The stock chain is 630 x 96. You can get OEM parts at www.babbittsonline.com/parts/viewbybrand/parts.aspx

Rear sprocket is $52.91. front sprocket is $21.74 and chain is $201.07
Please rate my answer. Thanks.

I did the same upgrade with the same bike. put a 16t in front and 64t in rear, never had a problem. just more power. I did notice when the chain was to tight things werent working right. gave the chain a little slack and the bike performs great. you might want to remove the front sprocket cover and check if the end of the clutch cable is installed properly. Hope this helps!
