I had this problem on an imported box of bits (Sorry, but was a lambretta and still have it), had done a complete build, got age/date verified from LCGB, applied for the reg and had to take it to the local vosa on a trailer who checked the eng and frame no, I did get it moteed on the frame No first and insurance (they give you 30 days to get the reg No), insurance from Footman and James), I gave them the insurers a call when the reg took longer than expected, and they extended the 30 days for another couple of weeks till I got the reg and got it transferred to reg No. Very messy, cost was about 50 quid from memory for the reg and paperwork. paperwork is a must which you can get from the local post office. Also note that you cannot sorn your bike either as you must pay at least the 6 months duty. hope this helps
