yeah reverse is probably my easiest gear to find for me hahaha one issue i have with mine is that it will pop in between forward or reverse on the reverse handle... it only happens after i just came out of reverse... i must have something worn or something... cant figure it out... i just have to make sure it is in forward real good after i use reverse
there is alot of problems with the regular gear linkage and guys are using yz250 levers to solve that...
we also like to put oil coolers on them so they can be beat unmerciful and not get too hot. i mean when i ride mine, i take it easy till it warms up and then its straight beating thereafter.. it loves it! thats why i bought a warrior...
if i were you i would ride it for a couple days just so you can relax (its always that way with new stuff, all you wanna do is ride it every single minute of the day) but after a couple days or maybe like 3 hours of riding, i would get serious about checking everything out... greasing all the fittings, adjusting the chain, changing the oil, adjusting the clutch lever and brakes, replacing any bushings and bearings that are surely shot, you might even wanna check the valves, but mostly just general maintance stuff since the guy that had it before thought it was an old junker and probably hasnt done anything with it since the 90's
after that you can take it out and just hammer on it and you wont have to worry about a thing... tick around here and read as much as you can bear.. youll catch on quick....
