Hey guys, i have an 04' gsxr600 and i am getting ready to change my sprockets. I went -1 in the front and +2 in the rear. i was just wondering if i will need to make any adjustments to the chain, and how far off i can expect my speedo to be and the easiest way to correct it. Thanks for any help.

You might need a new chain, It may fit but it will be real close. All there is thing called the speedo healer. It fixs the speedo problem. I have never used but I heard it works. OR you can get a mountian bike speedo, that are good up 180mph and they are dead accurate. i have been thinking about getting one. Plus they are cheaper than the speedo healer.

How difficult is the speedohealer to install? Does it just fit under the passenger seat? cops around here are pretty hard enough on bikes, a ticket is the last thing i want, especially if i can fix it.

Your speedo isn't accurate even from the factory so a healer or mountain bike speedo is the only way to go.. Personally I know I am speeding so I don't care.. If I need to get by the boys in blue I pace traffic.. Good enough..

yeah you lost 10-20mph top speed but that thing is really gonna kick.
and you will prob def need a new chain. i went -1 front and i wanted to see how much room i would have and if you put the wheel all the way forward you only get one extra link. lol you prob need a new chain, plus i would get one anyway.

I went up 2 in the rear and it was noticable but didn't seem to chop much off the top end... but it did make the bike tire a great more forward in the swing arm... still fit but barely..

The chain might work but, it will be close.
Your speed metter will be off by about 10 to 15 mph.
the lower gear will make it read fast.
Ex. speed indicated 65mph while actually going 55mph Ex.
Find somebody completely stock tires and gears (car or bike) and pace the speed.

But that isn't a bad thing... that means when you think you're doin 95 thru a 70 you're only doin like 83... :dthumb:
