Probably the millionth time this question has been asked…but here goes anyway!
I have a PX 200 with some mild porting and a 1mm plate under the barrel. Also a Sito plus. Mid range is much better then standard (not difficult!), and it revs really well also - except in 4th (surprise!). Goes nearly to 60mph in 3rd, then 4th needs downhill or a long run before it will pick up well. Once it does, it will get to 75. Hills or headwinds will kill it again. If I go for a T5 top gear, will the engine stand the higher revs? Just how bulletproof are PX engines?
Would a different pipe help, or is that likely to move the power high up the rev range?
I use the scoot for work, and A and B road runs, plus long trips at weekends. I only rarely use dual carriageways, never motorways (hate them - even in a car).
Next stop will be a kit, I suppose, but I dont want a tiring, revvy screamer, I much prefer mid-range power for the riding I do.
Any advice and guidance?
