well, finally picked me up a 250r. i have a BUNCH of questions!

what kind of oil...brand and weight..are your guys running(transmission)?
what kind of pre-mix oil are you runnin?
what ratio do you mix it at?
is synthetic better than conventional?
what kinds of spark plugs..numbers too?
what should i run in hotter weather...85 degree range?

anything else i should know?

any info would be GREAT!

that's all for now..i'll think of more later

THANKS

 

Golden Spectro 50:1 Ratio
NGK BR8EG spark plug [year round]
Honda Trans Oil for transmission

 

what's the diff between a br8es and a br8eg?

50:1 ...? isn't that a bit lean?

 

I have an '86R with ESR 310 and 9 port with new CR250 ignition. I run AMSOIL series 2000 full synthetic at 50:1 with 110 race fuel. I would definitely go with a full synthetic oil. Transmission oil is Honda HP 80/85W. Plug is NGK B8EV, year round.

 

ive been racing R's for a while now and i dont agree with KNOWSALOT on that oil ratio. that is very very lean for a 250R. i would highly suggest using bel-ray MC-1 with a 32:1 ratio. i also run bel-ray gear saver motor oil that has never failed me. i run a NGK B8ES plug but you can also run a B8ESV or B8ESR. this setup is perfect for any weather but like all two stokes you have to make sure it is jetted good. thats all ya sked so thats as far as im goin

 

The BR8ES has a standard 2.5mm center electrode where the BR8EG has a fine wire nickel alloy center electrode.

 

I run Golden Spectro @ 50:1 and it works fine. If the bottle says run 32:1, then run that. Golden Spectro recommend 50:1 so thats what I run.

 

i ran belray mc-1 at 50: since the bike was new in 86 and didnt need a rebuild till 1998..

 

crazyhorse, different oils require different ratios to be equivelant to that of another oil.

You wouldn't run MC-1 with that ratio, but you do with the Spectro.

We sponsor over 100 enduro motorcycle racers and ATV racers all across the south and all use the Golden Spectro at the 50:1 Like I said, it depends on the oil you use.

 

ya sorry i just realized that
