Hi there, In all part lists the engine of my Thunderbird is supposed to have 70 HP but following the inscription in the swiss papers I have only 54HP. What can be the reason? Thanks for your answers Jan
I believe the thunderbird version of T300's had very mild cam timing , lower compression and most likely timing and carburetion to suit. They ranged from your 50'odd to the super 111 which I think was just over 100'ish . But the super 3 was very hot cam's and had to pull a lot more rev's to do it.
No actually it says 40.5kw. As if there was a reduction. But this would not be logic. The limitation of the new driver motorbike licence in Switzerland is 35kw...
