iv just got a 172 runner its got a scorpian exhaust and 180 2 gearing its dynoed at 20 bhp and i want to make it quicker any advise on good mods and advise on rollers would be great cheers
sell your exhaust and get a good one like jolly moto or tdr of a pm59 scorpions are like stock wer was it dynoed psn? get a bigger carb 2 sumin like 25-28mm better crank bgm or sumin get porting and flowing done
depends what you want from the bike tbh scorps are ok as everyday use and big miles. you could try bigger carb setup or personally i would go for a good full circle crank and cases flowed with some barrel work too. then you can go on from there knowing that your bottom end is sorted
