I'm pretty much done with everything I can on the MAR now Spen and have to wait for the stuff to come back from the paint shop. I reckon a few days will have this thing back together. I'm not going upto Croft next week so that will give me something to do. I see you've replied to my post on the TY80..the youngster fancies having a go now as well so the TY80 has had the covers taken off. They do say that you should only do one at a time don't they?

Hi Spen CW here. Yes the thing was running a year or so back.

Afternoon all. I'm just getting into this trials thing as I fancy doing a bit of mud plugging in the winter down here in Somerset. I live in the Quantock Hills so not too far from some lovely routes, although I know the area of outstanding beauty lot have had most the trails closed. I do know some local farmers who I'm sure will let me shred their fields and woods though. Anyway I happened across this OSSA MAR in the VMCC magazine a few weeks back just down the road, so I duly popped over and bought it off the chap. Nice little bike; hand painted in Hammerite with the tank and panels in Dulux non drip gloss. Suffice to say the bike is now a crate of bits with the frame off to be powder coated while I tart up what's left. Engine sounds sweet with all the gears. I've never done a trial before but will be looking at joining the folks in the Somerton or Taunton clubs in their twinshock class. Having said that I popped along to watch a trial with the Exmoor club and they only had about 3 twinshocks entered and they were all Fantics. Nothing Spanish to be seen anywhere. Have I bought the wrong bike? Makes no difference does it, as long as your getting dirty and having a laff.

Hi I bought a TY80 some time back for my daughter who now has a renewed interest in having a go at some trials with me. It's a bit of a mess by all there. Anyhow I tried starting it a couple of times and no luck. Here is the current synopsis - carb rebuilt with new jets and gaskets - lifted the head, no problems there and fitted a new base gasket and annealed the head gasket. No movement on the crank - compression test shows 100psi - good spark, running an NGK B6 plug - petrol getting through as plug is oily - checked the reed valve and that seems to be seating alright. I'm thinking that it may possibly be the crank seals? Any opinions or how I could check. In the past I have made a plug and pressurised the cases to see if the vaccume is held. However there may be an easier quicker way. Also if they are gone how hard a job is it to replace them. I assume I'll have to split the cases? Or can you just drift them in? Having said all that, take a step back and see what is a beautiful Jewel of a bike. Perhaps I should have bought a TY instead of my OSSA
