Ok so I had the bike out it still does it, shifting would start to get harder after about a mile and almost impossible to shift after about 5.5 or 6 miles, I didnt pay attention when it started getting tighter but at 7.4 miles I couldn't shift again.
Bike has 10-40 in it per the owners manual its heat related so I pulled out the infrared thermometer and got about 160 anywhere on the crank case I shot it at, about 260 on the cylinder head by the exhaust port and the head by the plug the side and back if the head and jug were all about 220. I dont know exactly where the trans is on these things to try to get a temp of the trans if possible.
So my mind is going to transmission oiling or lack there of and the trans is overheating possibly but not the engine? But I dont know how the boiling system on these is for the trans. I know my trail 90 there is a small hole that the oil gets to the trans that is known to get plugged up, anything like that on these things that I should be looking at/for before I finally bite the bullet and just take it to a shop?
I should add the bike has 1300 miles on it and those temps where taken after a long steep hill
Thank you for all the help
