no need to use a bigger carb as harry says 22mm is perfect for his 175 stg 4 as i have one .
ive had a few 175 cast iron barrels including a harry barlow one and although harrys performed the best, it suffered from overheating/seizures on any sort of long run at constant speed of aproc 55mph/60mph, which is wot all cast barrels that have been oversized to 175 tend to do,so i would put your money to better long term use and get urself a muggy186 iv. ive been running one on my series 2 with jetex 26 mm carb/fresco pipe/li50 gears with 15/46 setup or 16/46 with a clubman.pulls very respectably low end and will rev out for ever and cruises at 55/60 all day with 70ish available if thrashedgoffy wrote:does anyone have a Harry Barlow (pro-porting) 175 barrel on there scoot that he has ported to let me know how it performs incomparison to the 186 Mugello kits. My head is quite screwed up as to which way to spend my money,if i don't spend it soon my Mrs will find use for it!
porting my Tv barrel, mugello IV 186,rt195. i kow there are extremes in pricing on these options which is exactly whats making it hard to decide.i am going to have the crank upgraded etc for the extra performance, but will more expence really make the performance that much better for two, maybe three times the cost?
want an engine with touring tune not fast road.
you know it makes sense rodney
