Hey guys... Just got a question about primary spring. I have a 2015 174" T3 with a 872 Trygstad big bore, I bought it used with 600km on it and now there is 1800km. I took my primary clutch apart for an overhaul but the spring that I removed is not stock and of course the color code is not visible and I can only see the bottom half of the numbers because they are rubbed off. My ramp angle is 441 switched from a 438. I have not checked the weights yet but I will tomorrow. Would you guys suggest going to a stock spring (purple/pink) or a stiffer spring? Oh and it has a race team secondary in case someone is wondering. Thanks for the advise!
