Kev Mods - are they worth it?
 

You bet your golden watsits they are!

Had my bike for 18months now and done 2 reasonably testing trips. I know i know i'm a lightweight but gotta pay bills. I installed the kev mods (O2 and fuel mod) then a stage two DNA air filter thing and it's like a new bike.

mines a 2010 with stock exhausts so didn't really have any surging but it had the crazy throttle power jerk when coming down from speed. I was constantly changing gears to get at the power and the popping was a bit barmy.

All smoothed out now. Even acceleration, hardly a pop and no snatchy throttle when coming down from speed.

I don't know what my fuel economy will be like but I never got the 300 miles per tank that some mention anyway.

So all good.

They are both great mods and excellent value, you get a lot of "bang for your buck".

Me neither, I could just about strangle 250-260 miles out of a tank full even when riding like an old granny. What I will say is that the addition of the O2 controller alone did improve my mpg by about 5% over stock. I run a PCV and Stage 3 intake now and I'm back down 10% from where I started in terms of mpg, but the bonus is power is up from 43 to 53 rear wheel hp, which is very noticeable! :D

Hi Daz, well worth doing the throttle mod too, it's free and makes the throttle action so much nicer!.Steve

Mpg improves a lot if you decat the pipe and drill it. Mine went from 55 odd to 60 plus mpg.

Drill the standard cans? Not heard of that, any more info on it pal
