May 22, 201016 yr Just picked up this wreck! I bid, didn't expect to win but here it is! Question is what is it? There's a Yamaha engine stuffed in at the moment. any idea of the size? Any way here's some photos. Edited May 22, 201016 yr by BigMike1961
May 22, 201016 yr Author Heres another photo! It's got chrome (well they used to be) rims, 17" rear and a 21" front and rather spindly forks 30mm I think. Oh and the most shot front wheel bearings I've ever seem - 3/4" lateral play at the rim The motor has got to go - flea bay so an ID of the engine would be very helpful.

May 22, 201016 yr hi what you have there ia a montesa 123 rolling chassis (i think) witha yamaha dt175 engine (or dt125) .Regards Paul
May 22, 201016 yr You should be able to see the engine size stamped on the bottom of the barrel , it is a t shock DT motor 100 - 175 ?? Could be a road RS engine maybe??
May 22, 201016 yr Author Thanks for the replies, it turns out to be not big enough for my cunning plan involving an Xl185 motor... I think I'll have to move it on to another owner in the shorter rather than the longer term. Oh well, Ebay here I come.
May 23, 201016 yr I just noticed the amazing bit of plumbing where the exhaust pipe leaves the barrel. I've never seen a header pipe squeezed into such a tiny gap
May 23, 201016 yr It could be quite interesting if you stuffed a ty175 motor in place of the lump that is there now . The hard part (the exhaust ...) looks to already be done ... Just a thought ! Glenn
May 28, 201016 yr Author HI SCRAB http://www.google.com/imgres?imgurl=http:/...%26tbs%3Disch:1 cheers Hmm that looks interesting, My french isn't too good but it looks like they've got a 125 honda into the Montesa 123 frame. There is hope yet. The exhaust is amazing the bolt passes through the exhaust pipe to get the fixing into the barrel. It's a 97cc lump, I put me specs on and found some rather small castings giving the cc's.. I think I'd have to go to 21" & 18" rims, there's a 20 inch on the front not a 21" as I first thought. Is it a problem changing rim sizes - obviously the spokes would need changing but the current ones are rusty as are the rims. I would have to lower the engine cradle to get the required height for the engine but then the sprocket might be too low to clear the swinging arm pivot I'll have to wave the tape measure around very carefully. No-one has remarked on the rear brake pedal?!!! Take a look in the second pic! What do you think? Mike Edited May 28, 201016 yr by BigMike1961
