That is defenately a piece of piston ring, you can see the notch on the end for the locating pin.
Like you say, strange how it ended up inside that cover, the only thing I could think as the previous owner had the cover off as he was lowering the barrel he snapped it off and it fell in there, he didn't see it and re-fitted the cove! (Only a guess, we will never know)
Ian, did you make sure there was no more pieces?
And the rings that was on the piston, where they broken (I.e. Was this piece missing from them)
Don't issue start numbers until they sign on at the event, then issue them as a lucky dip! So no one knows what number they will have until they start, have a cut off time for the entrants, then offer it to the reserve's (obviously before the main start time)
What about having a reserve list, and say to the main entrants you have until "x" time in the morning to sign on, (if your going to be late call us) then at least ones who want to ride may have the chance (unfortunately they would have to take their bike with them, but may not be guaranteed a ride if everyone does attend) but if they do, then it's free because the no-show has paid and lost his entrance fee.so worse case scenario you bring your bike and end up just watching a trial, best case you get to ride a trial for free!
Some good video's there, nice to see the two different classes of bike (twin and mono) riding together
What was the red and white bike in the first video at 2 minutes climbing the hill? I kept replaying it and I just can't make it out, am I having a mental block! ?
My 97 sections front disc rings when riding , serious floating rotor ... The sound distracts me but does not affect my balance or the performance of the brakes ... I should probably get some new bushing's or just take a few out and see how bad they are worn ... The rotor ringing at a standstill with just the clutch applied , no brakes , is annoying to say the least ...
Try the silicone trick first, just a blob on each one and let it set.
Mine was exactly the same as yours, and now it is absolutely silent.
If they are so bad that it effects the bikes control, then you need new ones. my discs move slightly, and I never had any problems with them making it hard to balance or effect the ride.
The problem I had was the chattering they did when riding with no brakes applied (when braking there was no sound as they are under tension) so to cure the noise, I did as Craig said, and just blob a little silicone on the collars.
Try that first, let it set fully, then see if that helps.
Enjoy your 315 they are a great bike, (don't forget to post a picture in "show us your monty")
Seems you got sorted, but other than fleabay, I have used www.vallmoto.com in past, they have a few of the rarities for the Cota's, as I'm sure you have found alrerady, new parts are very hard to come by.....!! please feel free to join my facebook group for twinshock and air cooled mono's, plenty of stuff to go at...cheers, Mark...There is a parts manual I think in the file section of the group for the 247 also.....feet up!
If they are good, then the cable could have been stretched, or perhaps the previous owner had fitted the wrong one.
As for the 2 spark plugs, mine is also the same (247) but only one plug lead from the coil, so I can only presume it is for a decompressor! (Unless someone tells me otherwise, and they are fitted with two plugs)
Could perhaps split the lead from the coil for the two plugs!
My side stand mounts to the frame near the foot peg.
Does anyone have or know where I can get a front hub for my cota 247 (21M)
I have been writing a list of parts needing work or repair, ready for the strip down for the restoration
My intention was to completely rebuild them anyway, But I have only just seen the front hub is broken, I thought it was just a loose spoke, but the hub is no good! The previous owner (obviously) kept that one quiet and well hidden!
I should have looked a little more deeper! Oh well!
I also asked a similar question about my cota, and was given the information about southwestmontesa.com from another member on here (thanks nh014) it's great help.
They have all the info on the site, check it out. And according to that site your model was made from 74-77
is it a restoration (like mine) or a full up and running bike? (Pictures please!)
That's a new one on me, I got some for my 315 not long ago and heard nothing about that.
There are also plenty of other non O.E. Pads out there, and they probably fit other models also, I know my wife's quad brake pads look very similar, I kept one of the old ones to compare when I next change mine.
You say the disc is like new, but is it straight? I.e. Not ridged or curved,
If you fit new pads to a ridged disc, it can take a while until the new pads bed into the shape of the old disc!
If it is really flat then it's not that.
Does the lever pull far back? Could be air in the system, needs bleeding (should be done every two years anyway) so try that, because if a previous owner had done something and not bled it correct, that will give you poor brake effort!
