So you dont have alien tires.... oh well i have been wrong before. Those little RS's are fun i got to ride one once, i posted the same time round cayuga with the rs as i had with my 400 and i had several weekends on my 400 before i tried the RS. they corner like mad demons from hell. i wish i was a litle more mechanically inclined i think i would have picked one up by now. sweet machine pat. im envious.

Well as you saw at mosport....they are far from been alien..lol

I though it would take more time doing mecanic on it...but it's very simple mecanic.
I wrench less on my RS then Francois, Dominic and Sebastien have done on their bike..lol

only thing to look at: is the main jet and it take less then 5 min to change..the remaining is cleaning up.

the biggest thing it the engine overhaul..take about 3-4h when you have all the right tool. (my first time...pretty sure I can do it in 2-2,5h now) and need to be done once a year.

How often do you change the crank ?

There was an RS125 for sale at the race weekend for 1700$ i think...

the crank is good for 2000km.
piston 500km, cyl 1000km
in the vrra, we do a little less then 500km/year. (that's doing the 4 weekend)

I read a lot of people do 600 to 750km with a piston. and they still do 2 piston per cylinder and/or 4 piston per crank.

the cost involved is more then a 4cyl. but it's not hard mecanic.

You don't need to split the cases between crank change.....(unles you crash and sand get in it...lol)

the overhaul once a year(splitting the cases) I said is to check everything just to be sure and clean everything well...it's not 100% mandatory.

See what i mean...splitting cases....what is a crank shaft anyway I was about 2 days from writing a check for a RS125 this winter but then i finally found a motor to replace my blown up 400. So maybe after this motor goes, and the way i downshift it wont take long lol!! I may find myself on one in a year or two. I smile just thinking about that day at cayuga. they are way fun.
