Stuart,
I ,like you are aflicted with a TS 150 rebuild (I got the bug about 6 weeks ago when my son told his girlfriends dad that his dad could 'fix u'p the MZ that he had languishing in his rear yard !!
)
Anyway,to cut a long story short I parted with £20 & agreed that we could rebuild as a 'budget 'green lane bike
,ho hum.
Having now spent more than I would dare tell the wife on a ground up rebuild ,we are now getting there.We to, are at the 'high level exhaust' dilemma stage .Having taken on board all the experts opinion on how critical the original exhaust dynamics are ,I invested in an assorted bag of the correct size tube bends as the original down pipe.Armed with a new Tig welder ,I am about to find out just how difficult it can be to make a suitable 'high level' exhaust.I intend to make the pipework section from the exhaust port of the barrel ,up and over the top of the head and then utilising an old 'original' exhaust pipe silencer section ,run (with modifications) to the rear of the bike -as per the original ISDT bikes (well, very losely
)
Other mods I have so far carried out include removing the rear foot peg bracketry,removing all the excess metalwork around the rear subframe/mudgaurd,smaller seat,repositioning the electrics under the seat,wider/higher handlebars,and fitting a high level front mudgaurd(off a Can Am Military bike) .The bike was originally a 1983 TS 125 ,but i have fitted the 150cc engine to hopefully improve the performance a little.
I'm hoping to finish in time for the Beamish trial in September,but who knows .........I think this exhaust will prove to be a bit of a challenge !
Anyway ,its good to here Im not the only one with the issue ..
,
If you have got time ,give me a shout -would be good to compare notes !!
All the best,
Steve Gale
