| Same here as Phil - although I've got a budget if I had known that the 600SS would be this much down on power I would have gone for the cheapest 620 I could find.
We've hit the wall with the valves when it comes to getting more power out of the big-bored engine and we can't change those within the rules.
The cost of Keihin FCR39s is knocking on $1000 (about £600 as Phil says) once you've got them imported and so on, plus you need the shorter manifolds as well and I haven't been able to find them here either. |
