1973tr6 Posted November 27, 2014 Report Share Posted November 27, 2014 I an taking a bit of a guess here .... but I don't think the slide should look like this.... Plus the pilot jet playing silly buggers and not coming out for cleaning and the needle being rusted up signed it's death warrant..... OKO on order......

bondy Posted November 27, 2014 Report Share Posted November 27, 2014 yes looks well worn i replaced mine not to long ago. sometimes you have to poke the needle jet out with a small screwdriver. if it's rusted up better off just replacing the carb as you say for a oko carb or a mikuni.

pschrauber Posted November 27, 2014 Report Share Posted November 27, 2014 A new carb is a huge investment compared to the slide and some jets an needles. At least where I live as here you can get parts at a lot of places and you know the standard set up for the Bing too. 1 Quote Link to comment Share on other sites More sharing options...
mike350 Posted December 16, 2014 Report Share Posted December 16, 2014 Sorry to say that mine looked a lot like your slide, maybe a little worse. I've replaced the slide and needle with new parts but I suspect that the carb body is worn too. It's not picking up cleanly and seems to flutter at low revs - it's hard to describe. I have a new Mikuni to fit when I have a chance and the guys at Bultaco UK say that the bike will run noticeably cleaner with the Japanese carb. I tried to avoid it because I wanted to keep the original look of the Bing, but I think in the end, the £26 spent on the new bing slide would have been better invested in the Mikuni. Good luck 2 Quote Link to comment Share on other sites More sharing options...
jon v8 Posted December 16, 2014 Report Share Posted December 16, 2014 About 25 years ago my neighbour had a 325 which ran like a chaffcutter. I realised that the carb on my new Fantic would go straight on to the inlet rubber.Without any adjustment at all it completely transformed the bike. A worn carb goes in the bin - simple as that,its no good for a rider who actually wants to compete.I've said this many times - the biggest thing with a trials engine is that it responds cleanly each and every time you open the throttle,you have to be able to trust it.A new carb will respond to tuning and along with all the other bits and pieces you need to have in place,make the engine run properly. 4 Quote Link to comment Share on other sites More sharing options...
2stroke4stroke Posted December 17, 2014 Report Share Posted December 17, 2014 I seem to recall that the Comerfords riders were replacing Bing slides every couple of trials back in the day such was the wear rate. I'd go for something better - you can't see the carb when you're riding the bike Quote Link to comment Share on other sites More sharing options...
