Going back to standard gearing

@Dusty ST

Compare the figures in the two diagrams...The top one is with standard gearing 18/41. The lower one shows the modified gearing that you are riding with. Thats a drop of 33mph on top speed

If you're not in a huge rush to change it today then Hunters Motorcycles on Ebay do a DID x-Ring chain and JT sprocket kit for £87.49 delivered.

Sounds like a very good deal, unfortunately I've already bought a C&S kit from Wemoto, and paid quite a bit more 
All good to go now, probably be August by the time I get round to swapping.

Regarding speedo recalibration, my 14 has a 'Yellow box' https://yellr.com/ sitting in the tail, looks like there's enough info on the website to get the speed spot on, probably easier and better then ditching it.

Good grief... I bought these bits nearly a year ago, and I've finally got around to fitting the C&S this weekend in lock down
