Hi all, I just bought a honda CR250 it's really good condition and everything works perfect, The guy i bought the bike from said he ran the bike at 25:1 but my dad who has 2000 honda CR250 runs at 40:1, Can you please suggest on what i should be running at?
Could you also suggest some decent oil to buy.
Thanks Phil

i run 32:1 in all my dirtbikes, it just depends on how the bike was jetted and what it was used for....

32:1 Is what the service manual recommends I usually run what the manual says and i run Belray H1R 2-stroke oil i tryed alot of different oil and it seems to run the cleanest without gumming up the exhaust valves. I ran it in my cr, my kx, and rm it performs excellent in all.
