lallasro Posted June 10, 2014 Posted June 10, 2014 carbs? I have a carb on my bike and I don`t know? ) under 40 you must be in 3. this is the bike, 30 m/h change to 3, 40m/h to 4, 50-55mph to 5. when I had fitted an o2jack, I manage to run with no problem at 40 m/h in 5th gear.
Noise Posted June 10, 2014 Posted June 10, 2014 I manage to run with no problem at 40 m/h in 5th gear. I can do 30mph in 5th easy on my 650
Noise Posted June 10, 2014 Posted June 10, 2014 A lot of race cars and drag cars do it Ttasky, sounds like they are picking up revs then dropping below tick over constantly
stewarty Posted June 10, 2014 Posted June 10, 2014 get a 02 mod of ebay £16 did work a treat with my bike
lallasro Posted June 10, 2014 Posted June 10, 2014 I can do 30mph in 5th easy on my 650 we are sure about this. you need 6 speeds if you want run with 40 m/h ) I bet foamy will beat you on his 50cc at squire hahaha
wild foamy Posted June 10, 2014 Posted June 10, 2014 I used to get 50 out of the donkey flat-out on the limit for around 20 seconds before it started to pinch up...
lallasro Posted June 11, 2014 Posted June 11, 2014 read the description most people say this will not increase your fuel consumption but on my bike was increased with something like 10%. you will not see any better thing on low speed but is allowing you to run your bike in up gears at lower speed... like 40 m/h in gear 5... normally under 50 m/h you need to change to 4. be aware about the speed, I mean your speedometer will look what values I just write up because is built to show less speed with 10%. so, if your speedo is showing 40, you probably will have just 36-37 and at 50/h probably you will have just 45-46. you can check the right speed with a gps. this is a general thing on bike speedometers, my mechanic, one bike instructor and one bike police officer confirm me this. my o2 mod die after 3 months and I don`t replace this because of fuel consumption. if you ask me, was a waste of money. 17 pounds the mod and 10% more on fuel . yes, you need id if you install a power commander.
clarke Posted June 11, 2014 Posted June 11, 2014 XVS950 is injection not carb. +1 on O2 mod to smooth out the surging you're experiencing.
