Hi. Just got a 1959 bantam 175 trials bike. 

D7 engine, 3 speed box. Both original I believe. Wasn't road registered until the 90s

Couple of questions, it does seem to really get going that well and it won't idle without cutting out and it also smokes quite alot.

I have adjust the fuel/air mix and it seems to run abit better now but still won't idle. There was fuel in it when I bought it so I've drained that out today and left neat petrol in the tank to clean it over might and tomorrow I will fill it with new fuel. I think that will help it run better but still not sure why it won't idle. Anyone got any ideas what else I could try please? 


Also more long term what can be done to give it abit more power? Obviously never going to be a fast bike and it doesn't need to be but the way it ride now just feels like it could do with abit more umph. But as this is my first classic bike I have no idea where to start with any upgrades really. 

I'll try uploading a picture of the bike to try and get some opinions on its originality etc.. I've just tried but it says file exceeds maximum size. Any idea why that might be would be appreciated too. 

Thanks in advance

Hello and welcome to the forum.

If you read through the various sections of the forum (you probably bypassed them on the way to making this first post) you will find all the problems you have mentioned have been covered. The Tutorials section explains about pictures, FAQs most likely cover the rest, or maybe in D1, D3, D5 & D7 areas or Trials, Offroad and Greenlaning.

The first section is for introducing yourself, so we know a bit about you - your history with bikes, skills, etc - which helps us to judge what sort of info you need.

the max file size for pictures is 1 megabyte.  To get under the limit I usually Email the photos to myself and choose a small file size before I send, works for me!

Look forward to seeing your bike.
