After reading the forum it seams most people use 2-stroke mix at between 60:1 and 80:1, so are there any people who use 50:1 mix of quality Stihl 2-stroke oil? (Performance class: JASO-FB or JASO-FD inc ISO-L-EGD)

Dose anyone know the recommended (by Montesa Honda) performance class of 2-stroke oil for the y2k 315R or 315R in general?

Lastly, rear fenders/mudguards, can anyone with any degree of certainty as to which modal years will also fit a y2k 315R besides the obvious y2k one it seams mine has the correct colour of fuel tank/cover (black) with the correct decals for y2k but the rear fender is red (also cracked and repaired!) and looking at available price lists they seemingly vary between ~>

Hi there,

Most Mont 315r's ran 70:1 on fully synthetic oil.

And yes a 1999 fender would fit as the the 315r's were pretty much structurally un changed from 96-04.

I had a 2003 model, the 315r is a legend.

Hi

Thanks for the reply.

Got another job to do on it, the front wheel bearing has a little play in it but joy of joys the spindle is stuck in the wheel bearings (had to take the forks out to get the wheel out ) but I still went for I little ride first (1st time in years), I think I will go the way of good SKF ones as I can get 6 for the price of a

Always do it, doesnt matter what bearings you get, there is very little grease in any of them. Last for ages then

Thanks,

Just done the bearings, ended up having to dismantle the bearing on the disk side so I could get a little side wriggle to free the spindle from the bearing the other side, then had to put the bearings back into the dismantled one so it could be knocked out

I pulled off the inner seals and packed with CV-joint grease as it

Yes there are stubby levers to fit your 315, but cant tell you where im afraid, rules
