I have a 98 warrior which is all stock. It was jetted at 135 and was running to lean and overheating. I jetted up to 145 (stock) and in the plug shows almost white on the end but is carboned up on the electrode and upper part. Seems to be running to rich yet I am confused about the white tip. The filter is clean and oiled but not sure if the foam may be breaking down and not letting enough air or maybe the exhaust is getting restriced and not moving enough air. I know the best thing would be put on better air filter and new exhaust. The problem is I want to sell and get a better bike to put my money into. Would appreciate any help
Thanks
