Mark Hooton
Cymarcbikeparts
Although I have had a GS-LC Hilltopped, what I like about Mark's 'easy' is that I presume that you can remove it each time you change your bike to fit it to the next bike, I change my bike every 12 months or so, and getting each one hilltopped could prove quite expensive.
However my new 2017 E4 GS is the best so far...very smooth fueling all the way through the rev range, although to gain a little extra power is always nice, providing it is with a nice smooth delivery.
I look forward to reading a few more posts on this new device.
Hi Geezer
this is another thread which goes on about the Evo (being the next step up from the Easy) but does give a customers view of the improvements which ca be had from this range of kit. Worth just reading the first post!And I`m chuffed you`ve got such a smooth running bike fella
