I do know that it will drop my over all top end speed, but I dont drive 180! However I dont see how my gas milage wont change? If I drive at a constant speed, say 75, my engine will be at a higher RPM with the -1 +2 than if it was stock. Or am I incorrect?
Again, thank you for your help, you guys have been awsome and got me thinking about what to do!

 

it does affect mpg a bit. gets a bit less and i drive in that range, mostly lol. i got an 05 and put a -1,+1 520 conversion and it def takes off the top end but it sure as hell gets there awhole lot quicker. im thinkin mine is prolly toppin out a lil over 150, maybe round 160 if im lucky, but i also have a lil more into it. def gotta get another chain now, along with a new rear sprocket tho, but its worth it imo. maybe even go +2 in the rear this time. def was way sluggish in first gear before i did the conversion.

 

well it depends on your habit of riding.. I'm usually in 5th on the freeway hitting about 6-7Krpm's but when i do a 525, -1,+2*.. My rpm's will probably be 8-9Krpm's in 5th, so i will probably have it in 6th now and be balanced out.. I like to be alittle rough on my bike (i get about 125 miles *when the light comes on* and this is no high-way miles.. so i never touch 5th or 6th gear) I know alot of people are thinking about gas prices like crazy, but a -1,+2* will not curve it that much but you get alot more acceleration, i've heard it makes your bike feels completely new. You can even just do -1,0* and it will be atotally different bike to you and you wont see a difference on the MPG. Actually if you want to be ballzys, the 520 would be less rotation mass which is less stress on the motor - so it might be better on MPG but that's just a theory of mine.. The money you do save, you will probably just put back into new chains .

Remember when doing a sprocket change, get a speed-o-healer or you will be racking bullsh*t miles and the wrong MPH

*(taking 1 tooth off the front is like adding 3 teeth to the rear.. the more in the rear you have the better the acceleration and easier to lift the front)

 

also i dont know if you have a PC3 yet, but if your looking for MPG - this is a MUST. I've been a slacker myself but i've seen a guy do his 06 1krr and that thing was a totally different bike from hooking up the USB to laptop.. freaked me out. (i just was having too much fun on my bike, but now it's time to have some fun with mods)

 

The 520 conversion is fine if you buy a quality chain and sprockets. I beat the living hell outa mine and its in great shape after 5k miles. You shouldnt have to spend $300 either, paid about $225 for my setup if i recall correctly.

 

yeah was just giving a ball-park (havent looked at much lately)

 

I was told to get steel sprockets cause they last longer but it wasafter i had gotten mine already but so far so good. I paid $170 for the kit (sprockets and chain)

 

Ordered my new chain/sprockets. Ended up going -1 on the front, how far off will this affect my speedometer?

 

if you only went -1 in the front you should be fine and your speedo should work the same from what I've heard it still makes a nice upgrade...

 

it will affect your speedometer a bit. when you install the sprocket, find a radar detector (cops leave them around town all the time) and just a couple of different speeds and write down each one (the one from your gauge and the detector) here is a linky http://www.hooliganbiketech.net/hond...frameindex.htm*

*(instead of going 1 down in the front forSpeedy- he went +2 in the rear, same thing but some people say if you going up in the rear instead down in the front you dont experience much of a vibration from the new setup - this is hear-say tho)
