mcman56 Posted February 13, 2018 Report Share Posted February 13, 2018 Is there a way to make the TY175 clutch more progressive? I have the clutch extender and put in some heavier oil such that it drags until warmed up. Those two things helped but I'm wondering if there is anything else.

turbofurball Posted February 13, 2018 Report Share Posted February 13, 2018 Do you slip the clutch much? I just stick it in gear and use the throttle for the rest 1 Quote Link to comment Share on other sites More sharing options...
carl ekblom Posted February 13, 2018 Report Share Posted February 13, 2018 I don´t know anything about Yamaha clutches but generally speaking: Clutch centre and clutch basket must not be notched and clutch plates must be in good condition. I think thin oil is better than thick oil. I use engine oil 0W-20 to get a drag free clutch Carl Quote Link to comment Share on other sites More sharing options...
feetupfun Posted February 13, 2018 Report Share Posted February 13, 2018 Ty175 can suffer from a pitted/worn surface on the camshaft which could cause it to engage more suddenly than normal. The pit forms where the pushrod rubs on it. I agree with Carl Ekblom that the condition of the plate driving surfaces on the basket and hub are very important for progressive engagement and is probably the most common cause of poor engagement and disengagement on TY175 clutches 1 Quote Link to comment Share on other sites More sharing options...
tyguy Posted February 14, 2018 Report Share Posted February 14, 2018 If you need to use the clutch on a section then you are in the wrong gear. This was the biggest lesson I learned with twinshocks. I don't touch the clutch now Quote Link to comment Share on other sites More sharing options...
guy53 Posted February 14, 2018 Report Share Posted February 14, 2018 I know I should not say that but the clutch is such a good friend in some situation. Guy 2 Quote Link to comment Share on other sites More sharing options...

The clutch on a TY 175 should be nice and light with a smooth take up. Too thick an oil will cause more issues, follow Carl Eckbloms suggestion for oil grade. A good look at all the parts of the clutch including checks for buckling etc and careful assembly following a manual should produce a more effective operating clutch for you. Clutchless gear changes should be ok on the TY if you are sensible about it. TY guy has the right method, clutch is for emergency only in section, assuming you are in the right gear!

mcman56 Posted February 15, 2018 Author Report Share Posted February 15, 2018 I am used to a modern bike. When I ride a TY, I try to ride clutch out. Occasionally, a turn is so tight I pull in the clutch to be able to go slow enough to make it or maybe hesitate before continuing. When I go to let it out, it tends to abrupt at the almost zero speed I'm going. It is probably by design but I was wondering if there was a way to improve. I have the smallest front sprocket (11?) and the stock size rear sprocket. Quote Link to comment Share on other sites More sharing options...
feetupfun Posted February 15, 2018 Report Share Posted February 15, 2018 It sounds like you are trying to turn like you were still on a modern bike, and it isn't a modern bike. The techniques required are quite different. 1 Quote Link to comment Share on other sites More sharing options...
b40rt Posted February 15, 2018 Report Share Posted February 15, 2018 Learning to use the clutch in sections gives you an advantage. There are many sections where there is no "right" gear, slippery conditions, or a tight turn onto a steep climb etc. Persevere with getting the clutch right, it will make you a better rider.

turbofurball Posted February 15, 2018 Report Share Posted February 15, 2018 FWIW, despite my flippant first reply, my clutch is smooth as so I suspect you need to give yours some attention. I just threw normal 10w40 oil in last time I changed it. I have a modern steering angle on mine, too, which might give an advantage on tight turns (?) thinking about it I've only really slipped it at all when on full lock and below comfortable tickover engine speed. I have a 12t front sprocket and ride 95% of the time in 2nd gear. 1 Quote Link to comment Share on other sites More sharing options...
guy53 Posted February 15, 2018 Report Share Posted February 15, 2018 You should also have a look at your cable and it's routing, I know they are different, but the clutch on my TY 250 is smooth and predictable. I change the cable and keep it well lubricated, I also use a longer lever. It is very light to a point that some of my friend thought I ad taken spring out. 1 Quote Link to comment Share on other sites More sharing options...
scifi Posted February 15, 2018 Report Share Posted February 15, 2018 Had a sticky cable on one of my bikes, and rather than get a new (expensive.) cable, I decided to try oiling what I had. I put the nipple end into a drill chuck and span the inner cable slowly, whilst dripping diesel into the other end. It took a lot of time and about 5 teaspoons of diesel before anything emerged from the bottom end. The first drips where really black, but after a few tries the diesel would pour easily down the cable. Then I put some normal oil down the top, and the cable was really free then. Hope this helps... 2 Quote Link to comment Share on other sites More sharing options...
turbofurball Posted February 16, 2018 Report Share Posted February 16, 2018 A quicker method is to use a cable oiler (£4 or so off of a certain online auction site), and blast WD40 through - takes a minute or so. IIRC Venhill recommend re-oiling after every jet wash (!) Quote Link to comment Share on other sites More sharing options...
mcman56 Posted February 16, 2018 Author Report Share Posted February 16, 2018 I have a new cable and it is not sticky. The pull is relatively easy. When you let the clutch out, there is not much lever travel between start of engagement and full engagement so it is hard to slip the clutch. So, I guess I'm asking if it could be made more like a modern bike clutch. Quote Link to comment Share on other sites More sharing options...
