That is exactly my worry! How can you tell for sure!?
In fact, I know almost for a fact that Lillee was raced in her previous life so who knows what sort of a past she has...
I know this much about Lillee's past:
1) I am at least the 3rd owner. The last owner suspects at least have been 2 owners before him (I am at least the 4th owner)
2) She used to be Cadet blue, then Jet red with a white roof (by the "2nd" owner), now classic red with a white roof (by the last owner before me)
3) She used to have another engine other than her original De Luxe 998 3 synchro remote. I am pretty sure Lillee has had more than 3 engines but for sure she's had: The original 998, a 1275 (or there abouts) with disc brakes and all, and the current 1098 that's in her now.
4) She has had at least 1 cam change via the side radiator grille entry method...
5) She used to have S overiders, bullbar, possibly a sump guard and Hella spotties in the front
6) She used to have a smiths pod mounted tacho on the indicator shroud
7) She's wearing LS contessas which were common with racing guys to maintain the stock no flares look and still have S brakes under the wheels. These contessas has stress cracks which is an indication that it could have been raced...
That's about it...
