I am posting from my cell phone because we have a power outage right now so don't hate for spelling and grammar errors lol.. so lets see, total install time was about 1.5 hours.. something that would of sped it up a lot is having allen sockets and not just the keys. the only tools needed way a 5mm allen head, 30mm socket, 22mm socket, larger adjustable wrench 12mm socket and 12 mm wrench and a plastic remover tool. Two other items to improve the job are a torque wrench and locktight..
first off remove the cover over the front sprocket, it should be 3 5mm allen heads. then while pressing the rear brake remove the 30mm nut on the sprocket. then loosen the rear wheel with the 22mm socket and adjustable wrench so you can side it forward. you will notice part of the clutch cable thingy (technical term) is in the way for removing the sprocket so go ahead and remove the one 2 5mm allen head bolts holding it in.. now slowly remove the clutch "thingy" as there are small things attached to the general area that may fall. now you can remove the sprocket. now that the sprocket is out you have to remove the plastic case saver. what you need to do is get your plastic remover tool (i used an angle grinder with a sanding wheel) and you remove the whole lip on the case saver, you will see what I mean. you have to do this or the larger sprocket won't fit. (now when re installing everything use lock tight on every bolt.) one the is done reinstall the case saver and install the sprocket and tighten the bolt to 61 ft/lbs. now reinstall the clutch "thingy" and sprocket cover. now just tighten do a chain service and check the tension and alignment your rear wheel and tighten it all up..
I had it up on a rear stand the entire time and the first thing I did when I was all done was fired it up.. after checking to make sure the rear wheel spun freely I then pulled the clutch and dropped it into first.. now if you have a rear stand you probably noticed even with the clutch pulled the wheel would spin, it no longer did this (i fist gear at least, I never tested any higher). after it worked good on the stand I removed it and took it for a spin.. first gear seemed so off it felt like I was starting in second.. I really didn't like the takeoff at all (until I got used to it)... but then once I got going I though wow this seems fast! but at the same time nothing was different.. before I would go 20 in second gear and I would be at 3000rpm or be going 60 in 6th at just a hair over 5000rpm.. nothing changed it still read the same.. but it felt faster so I went back to get my gps... and took it back out for a spin..
and the verdict is...
The speed and GPS read the EXACT SAME speed and i mean exact not even 1mph of difference!!
that's all I wanted for my speed to be correct, and with the addition of the +1 gear I get a higher top speed and ever better gas mileage..
to good to be true huh... the only downside it a loss of acceleration.. before this mod I felt I was faster than most lower end sports cars.. now I fee like we would be the same acceleration.. and as for the clutch in first gear.. after about 5 minutes of riding I got used to the new gearing and didn't have any problems what so ever..
this mod cost me a total of 38 bucks shipped.. I got a "driven (brand)" +1 front sprocket for solomotoparts.com
but the package I got says 99-09 R6 520 conversion sprocket, so any 520 R6 front sprocket should fit..
for anyone considering this mod I say do it unless you are craving more power then I suggest you got for a -1 front sprocket, but then your speedo will be about 15% off hahah....
