Ty175 Points, Condenser, Electrics Need Help

[dougalthedog]

Hi

Just spent the last 12 months restoring a TY175 nearly finished.

Bike starts but wont rev cleanly and bangs and pops.

Any ideas - i think its probably points / condenser - but electics is the only aspect of the bike I know nothing about.

Can anyone give an idiots guide to replacing condenser and points and setting up correctly.

Bike has has a nut and bolt rebuild including .25 rebore.

It will start but seems to have an intermittent spark - hence the popping.

Any one local to Skegness or Boston in Lincs who could help? - I can bring the bike to you - would be much appreciated.

Thanks

Just had similar problems with mine, replaced points, condensor and coil (not sure which was the cause but i thought might as well replace the lot in one go to be on the safe side.

Idiots guide: Take the flywheel off (you will need a flywheel puller)

The condensor removes with 1 screw but you will need to solder the 3 wires to the new one.

The points also remove with 1 screw, and 1 bolt holding the wire to them.

The timing is a bit trickier, there is a timing mark on the flywheel, it should be in the smallest of the 2 holes on the flywheel, this will line up with a small plate inside at roughly the 7 o'clock position, when that lines up your points should be open, measure them with a feeler gauge, they should be betwen 0.30 and 0.40 mm, its a bit fiddly trying to set them right through the hole but just keep trying.

Haynes manual will explain it a bit better, hope this helps.
