Speedo is off about 5-8mph and gets worse with faster speeds. I am not wasting any money on a healer because even with the healer it will still be off the factory amount of about 7%. This way whatever I see on the speedo means I am actually going slower which keeps me under the speed limit around town.

 

agreed, go -1 up front. i got a "quick acceleration kit" (520) for my 636. it was -1 up front and -2 in the rear... it gave me better mid range torque, but i ended up goin back to the factory rear sprocket after i toasted the Vortex sprocket and i liked it the best. you can find them online for under 20 bucks.

 

good info ... thanks doc

 

I think the -1 woke it up. It made mine more wheelie happy (no self control i know). I like the combo. I dont need to go 175 mph but if we race to 100 ill get there first!

 

that is a fact brother , i dig all the low end grunt , i leave the triple digits to the punks (street riding) . im lookin into that -1 ft sprock now. know the tooth count on a stock ft sprck?

 

Should be 16 tooth stock. Im still running the stock 530 but will probably go to the 520. Still debating because my sprockets are almost flawless after 2 years. Low end grunt is where its at.

 

ive got nothing against peeps who have the 520 kits , but two buds of mine have it and they are constantly having to adjust the chain, the smaller chain seems to stretch out faster .PITA if you ask me . especially if you got a bike just for the street. now a track bike where you want every little ounce off the bike i can understand , cause you have to adjust and maintain a race bike after every heat or so.... thanks for the info on the sprock , so im lookin for a 15 tooth?
