If you haven't already do read Bunny's excellent buyers guide
https://www.mtwc.co.uk/wp-content/uploads/2020/07/Final-150.pdfFor a 2012 you need to check/budget for the following:
Has the chassis got the factory/dealer fitted bolt in front chassis brace?
Does it have the Centa compensator or is it still soon the original Harley type. If Harley you need to change it for the Centa compensator and whilst you're at it have the Bleazey conversion done so you can access and change the rubber transmission rollers. Budget say £1-3k for this.
Has it had a steel rear drive sprocket retrofitted? If it's still the original alloy sprocket that needs changing - probably anything from £500 - £1k
Check the date codes on all 3 tyres, they are probably the originals which are over 12 years old and need changing regardless of tread depth. Put Blockley tyres on the front and I'd recommend a Michelin Cross Climate on the rear.
Budget for a full service with engine and bevel box oil changes and a brake fluid change.
If it hasn't had the "Comfort Steering" mod done then I'd highly recommend you get this done. As standard the car is prone to bump steer.
I'd also be replacing the fuel pump with the Walbro and getting a new battery (see the Alternative Parts list for recommendations, I use the Yuasa UR-1 which is £55 from Halfords.
Don't let the list put you off and contact Craig at M3WServices for a better idea of the costs of the various upgrades. He may also know of otehr alternatives on the market.
The Krazy Horse link didn't work for me but I assume it's this one

KH continue to specialise and support the M3W so you have the security of working with a dealer who actually knows about the car.
