November 9, 201411 yr Author Bilks: Many thanks for that, we a few guys this using chinese CG engines in tlr frames and modern front ends too, good luck with that project like myself, i never even bother to tot up my dabs, its a fun day out for me.....that and the fact i count myself lucky to be riding due to a chronic illness....keeps me active
November 9, 201411 yr If converting a mono, the bottom shock mounts are fairly straightforward, the top mounts take a bit more thought. Mono frames were not designed for loads in the area of top mount, and will probably require strengthened.

The bike should be more than capable to ride with modern iron, so what’s the point in chopping it?

November 9, 201411 yr iconic558 Looks like whatever you do,your going to be wrong,this is getting just like Stop or no Stop argument,But yes you will also need a brace on the rear frame,as mentioned by b40rt
November 9, 201411 yr It doesn't help the Naysayers that a TY Mono just looks so damn proper with two shocks on the rear ;-0 I REALLY regret selling my TY350 a few years back to get it out of the project cue...
November 9, 201411 yr Here's another take on it. A Cotswold / Mono conversion. https://scontent-a-lhr.xx.fbcdn.net/hphotos-xfa1/v/t1.0-9/1902900_712324955514371_4886112658257617960_n.jpg?oh=caa80b58dacea5ada894f80ef03231ba&oe=54DDF758
November 9, 201411 yr I give up Thanks for starting this thread. I have recently acquired a donor frame. The idea is to swap back and forth frames depending on what rules I decide to ride. Our nationals have an open vintage class. Air cooled and twin shock, no hydraulics is about it for the bike. Perfect bike for the open vintage class.
November 9, 201411 yr Ok,a bit of advice,the shock mounts on the swinging arm are fairly easy.The upper mounts on the frame are a bit harder,when I move them on Majesty conversions I use a little drill guide to help out when trying to drill a fairly large hole in a not much bigger tube.Its just a length of flat steel with a length of tube welded to it in line,at the right height to make the drill stay central when drilling into the frame tube.You can scribe a line down the length of the flat to help line up with the opposite side.If you look at these photos; https://plus.google.com/photos/109171438807732712015/albums/5694268572989036097?banner=pwa About 50 pics down you will see what I mean. Pay plenty of attention to bracing as already said,the subframe simply wasn't built to take these kind of loads.
November 9, 201411 yr Of course you could just put the motor in a Bantam frame. With the right exhaust it even sounds like a Bantam. The one I've seen does anyway. Edited November 9, 201411 yr by 2stroke4stroke

Pay plenty of attention to bracing as already said,the subframe simply wasn't built to take these kind of loads. I've seen alot of twinshock Yamaha TY175s that the subframe wasn't up to strength either,indication is the small strip of metal that is horizontal just above the swingarm pivot starts to buckle as the subframe bends upwards from repeated hard bottoming. Result is a slacked out front end geometry. Edited November 11, 201411 yr by htrdoug
