hi mate try not to use fully synthetic oil use semi synthetic and if its clutch slipping you will tell because when you put it in 1st gear it will jump forward or move a little bit but if not then your clutch is perfect also check chain tension if to tight will cause clunking good luck buddy :)

SOURCE: I just changed the oil
What type of oil did you use and how much did you use.
You should have used a 10w40 or 20w-50 weight oil with no additives (if it says "energy conserving" or something similar, don't use it) due to the bikes wet clutch.
You should have used 3.6 quarts if changing the oil filer at the same time as the oil, or 3.2 quarts if changing the oil only and leaving the filter in place.
I have a complete How To on changing your oil here:
It sounds like your motor may need to be looked at by a dealer, it sounds like it may be seizing due to lack of oil. The 'check oil' warning sounds like insufficient oil level. Do not start it ride it until you have it checked by a service center!

The bike has a slightly bent shift fork. The repair is a pretty major operation and I don't recommend the casual mechanic attempt it. Below is a diagram showing how the shift drum moves slider gears for different gear changes. Please rate my answer. Thanks.
