stevieb Posted February 19, 2012 Report Share Posted February 19, 2012 Just wanted to say Hi, I have just bought this 2005 SY175f 143cc I am really pleased with it, but I have no idea of it's history and therefore do not know if its had any of the common modifications done, I am keen to get the bike as good as it can be and would be grateful to hear of your good and bad expierences, what works, what doesn't work, what to look out for, which mods are worth the money etc..

andyrothers Posted February 24, 2012 Report Share Posted February 24, 2012 Think most people are running the exhaust mods and carb jetting changes. Small gearbox sprocket seems to be personal choice. I have a high rpm cdi but doesnt feel a lot diferent and a titanium front pipe which just looks nice. Some people re work the clutch actuator and the flywheel weight, neither of which i've done. Hope this helps Andy Quote Link to comment Share on other sites More sharing options...

Thats a nice looking Scorpa you have there. One mod worth doing is replacing the alloy chain tensioner for a steel one. Birketts do them, they are on the expensive side http://birkettmotosportukltd.co.uk/?Stop_Press_New_Product. The alloy one on my 125 bent first time out Quote Link to comment Share on other sites More sharing options...
archie Posted February 27, 2012 Report Share Posted February 27, 2012 andyrothers, you don't often see the mod to the clutch actuator mentioned much, but in my opinion it transforms the rideability of the bike and is one of the best mods you can make and if you can do it yourself, it's a no cost mod Quote Link to comment Share on other sites More sharing options...
andyrothers Posted February 28, 2012 Report Share Posted February 28, 2012 I've never really thought about doing the mod to the clutch - does it really make much difference and how difficult is it to do? Andy Quote Link to comment Share on other sites More sharing options...
dgshannon Posted February 28, 2012 Report Share Posted February 28, 2012 Owned one for almost two years. Great bike. Rejet on the carb is a must. Opening the exhaust, and removing all the cross brace rods was very worthwhile, as well. The other biggie was a clutch kit from B&J Racing. Made a HUGE difference in the smooth progression of the clutch. Quote Link to comment Share on other sites More sharing options...
