85 250r chain ???????

[saladboy]

i have a 85 r,does it matter what kind of chain i use. o-ring or non-o-ring? what the difference? is one stringer then the other or is it just the luberacation factor.what did it come stock with? Any input would be great.

Hey, it probably came stock with a non oring chain. I just bought a new one for my 85 and I bought non oring. You loose a bit of power through the friction of the o rings against the side plates. You wont have any problems as long as you keep the chain well lubed

trikebandit was mistaken they came factory with o-ring chains. get another o-ring chain for it the non o-ring ones streatch way faster. you'll be adjusting it about every timme you ride it. there was one on my 86trx250r when i bought after 3 rides it was so streched that it popped of and broke the cases.

with the RK X-ring chain i have on my 85atc and 86 trx250r i only have to adjust it after atleast 8 or 10 rides and it's only just getting ro where it recomends to adjust due to amount of play

I've ran a lot of good name brand chains over the last decade or so and Rocky Mountains Primary Drive Gold series x-ring will stand up to any of them for a fraction of the price. Check them out, I'll never waste my money on name brand again. FYI I tried the regular o-ring Primary Drive and it wasn't as tough. Don't forget to change those sprockets too. PD also has nice sprockets.
