hi mate
oil is spot on been working on bikes 35 years. all my bikes are 100% serviced right. i service my bikes every 2000 miles. the xt will get done every 1000 miles being a single. i have re checked the oil and its 100% right. run the bike for 15mins, then check the oil level, its about 6 or 7mm from the top so is right. going to change the oil filter back to an OEM one just in case as the one i put in was after market (but 99% its nothing to do with that) also going to put a brand new OEM clutch in next week at the same time, its only �79.99 for full set of plates and springs so may as well stick one in as it cheap and will only take me 40 mins or so to do, as when i start a ride the cltch play on the leaver is 2mm so spot on and after 15 mins (worm up) it has 15mm play so have to pull over and adjust it back. and when you have finished the ride and the bike cools down there is no play at all, so thats not right and noise maybe coming from there about's ? the only other thing i have done is from when i got the bike i have run it on the premium fuel, do not think that would do anything but will go back to standard fuel to see if it makes any difference,. thanks for your input.
