Brought home the 2012 S40 my daughter bought. The idle was way too low. Got home with 31 miles on it. Clutch cable too tight, absolutely no slack. So I loosened the cable. I have a little rattling slack in it now. And I turned the idle stop screw in 3 times while riding around today. Went more than a half a turn, less than a full turn. Sounds better and will now pop when rolling off hard or turning off. After the 600 service I will remove the brass plug and open the air mixture scew. Added about a third off a quart of Rislone ZDDP additive I found at O'riely. The web page
says adding 1 qt to 4 qts of SM rated oil will bring the average to 1200ppm. So I will use it to boost my first 2 oil changes. Just picked up the oil for my first change, some where around 150 miles. AutoZone had 10w40 Valvoline MC oil on sale for 2.99 a quart. Will add what needs extra with the Rislone product. Ordered 2 OEM filters off Ebay tonight. A freind is letting my daughter use a conventional clutch/transmission quad tommorow. She has never used a clutch so anything to try the clutch and shifting on 4 wheels. In a month she takes 20 hours of MSF training on a Honda Rebel. If she passes the course this satisfies the state riding exam. I may let her try start off, shift to second, stop and shift to first in a straight line in an empty parking lot a few times prior to the MSF. 30 years ago I taught my wife to ride on a BSA 441 round barrel Victor thumper. The more things change, the more they stay the same. Thank you all so much for this forum
