| Yes, I looked at the Sigma Performance page recently where Neil Spalding was taking about some Full Monty work on ST2's.
I spoke to him at TA3 about it and he was talking about a very, very similar specification with porting work done to the heads, a FIM chip, and taking it out to 966cc (I asked him whether it was really worth taking the capacity up a whole 22cc from the standard ST2's 944cc - but he said the pistons are high compression as well). I've obviously already got the ST2 cams.
Neil said that the ST2 engine was the best 2 valver to work on for this stage of tune because, being liquid cooled, it doesn't suffer from the overheating problems on the rear cylinder. The only main difference between CA-cycleworks and Sigmas work is that Sigma would make some airbox modifications (cut holes in it to improve the breathing) and put a lightened flywheel in as well.
Oh yes. The price? About 2K. Very tempting, but ultimately not reall worth doing on a bike that's only worth 3-ish thou as it stands. I think I'd rather put that 2K (when I get it) towards a 749.  |
