northerner Posted September 16, 2012 Share Posted September 16, 2012 Hi guys, just joined as I've just part-ex'd my old 125 after passing my Das recently at the ripe old age of 37! I'm very happy with my new purchase which zips along beautifully. 25k with loads of history. Is there anything I should be looking out for and is timing chain noise a problem on these as I believe I can hear it a little being mechanically minded ? Thanks for your help Link to comment Share on other sites More sharing options...
clancyblob Posted October 9, 2012 Share Posted October 9, 2012 I have a G-reg one of these as a runabout. I replaced the rear shock about 5 years ago with one from a breaker on eBay (a good source of spares). It was a b@$7ard of a job as the linkage is quite complex, and it's spent years under the mudguard getting drenched in mud and water. The only time it failed the MOT was last year and related to this - There are a lot of bushes in the swinging arm/rear shock, and these will wear. Just tightening the swinging arm nut will often take up some slack. A local mechanic made me some new bushes so the price wasn't hideous (I am a skin flint). There are 4 rubber tubes joining each of the carbs to the engine and they become hardened and crack, with the potential to allow air leaks and spoil the tuning. They can be over £100 for a set. However often the cracking is supeficial. I have found getting the carbs on and off a problem, I think Yamaha got 4 carbs then built the bike around them! It's just passed it's MOT again this morning. Phew! I have had two exhausts on it over the years, second hand 4 into 1 Neta. They do seem to corrode quickly around the beginning of the silencer, though sometimes a bit of welding can prolong it's life. They are not cheap, if you can even find one. Other than that, it's just the usual stuff that goes with old bikes, fork oil seals, flaky wiring, brittle plastic bits etc. Have fun but be careful!
