Here is the email from TVS regarding the parts situation.
At the moment, we are still preparing to re-open our parts department at our new site in Solihull UK. Parts of the delay in re opening has been compounded by putting systems into place for the first time, and also testing procedures we have put in place for parts designed, manufactured or sourced from the previous company (NMUL) now in liquidation. I appreciate that this doesn't assist with your enquiry, and we will always endeavour to assist customers if we can with the information that we inherited from the previous company, which is very poor and in cases non-existent. I can keep your details on file and get back in contact when I hear anything in regard to opening. Apologies for any inconvenience.
