can anybody tell me if a pc will make a big difference to a 636 b1h it has a k&n filter and a scorpian end can on the bike.

 

best mod you'll make next to a sprocket change

 

changed the sprocket on the front is there any other mods

 

what did you change your srocket to...how many teeth......also from what i have heard on here doing a -1 front and +2 in the rear sprockets are a good combo.....as far as the pc i would pick on up since you have a aftermarket air filter and exhaust you might be running pretty lean

 

i have the -1 +2 combo and love it, now the pc on the other hand seems to smooth out the throttle but no noticeable power gain. I ride with 056r with the same setup as me minus the PC and u dont see any difference. Im sure it will show up after getting it dyno tuned but thats JMO
