As you know I'm swapping the cylinder and piston from the 247 to the 292 tnt, since the motors share the same stoke you can use all the bottom end and just change the cylinder and piston, a machinist at work match the combustion area in the 247 head to the 292 head so I can use the head with the spark plug hole in the middle of the head. Above is he motor completely disassembled all parts that can be seen externally have been glass beaded, I think it looks great!! But I very knowledgeable member "Bones on the old ski doo forum see this picture and told me that the jug is from a 69/70 TnT and won't match my crank case.
Of coarse "Bones"was right, maybe you can't see it on this picture, but there are small differences that meant the cylinder would not seal on the crank case, I was devastated to say the least.
But Old ski doo forum to the rescue once more. One member "Elanmen" had a 70/71 jug that was right for me, and he needed a 69/70 jug so we did a swap, also my good friend "Goose" who sold me the first jug but didn't know that you had to have that particular year made me a good deal on another jug and piston, Unfortunately the jug and rings got damaged during shipping, top fin on the jug broke off, but the welder welded it up good as new and I' waiting for a replacement ring now.
I have painted up the frame skies and other small parts satin black to hide the small dents, did it outside with spray cans, came out ok I think.
I will start to put the track on the frame, I have got all new rubber wheels and bearings, need to de-grease sand and paint the chain case and secondary clutch, by then I hope the pistone will be back from glass beading and I can start putting the motor together.
GOT TO GET ER DONE!!!
