The 175 like plenty revs so don't be afraid to make it sing while getting RSI in your left foot changing gears.
LOL .. this from the man that told me to not rev the crap out of mine on the weekend, instead, short shift it and make it pull ... hahaha you're a funny bugger Stewart. But I must admit, after I got the jetting sorted, it pulled like a 14 year old and was a blast to ride.
Personally I'd leave it alone if you were going to vinduro it .. but if you're flat tracking it them port the shit out of it, redo the squish, and go for a 38 or 40 on methanol
But seriously, there is probably a lot more performance to be gained from putting a decent expansion chamber and muffler on it and then jetting it accordingly.
