Listen to the sound of this restored TV175
about every item on the engine is new:
-seals &-bearings
-GP cranck with TV conrod and standard GP 6-pole
-piston and bore
-bigbore exhaust
-80 link chain
-clutch & gaskets
Although the engine start and runs well, I found it has an annoying rattle, best
heard at idle. I've tried to minimize the parts used,
to localise the rattle. So the engine was run (for a short time) without cil and
flywheel cowling.
In my opinion the rattle comes from
-piston slap (new bore with only 1000km has about
.15mm/6 thou play measured at 1 cm from cil bottom at 90° from gudgeon axis with
a feeler gauge)
-or small-end needs piston washers. The big-end has about 0.8mm sideplay play
the small-end 2.6mm)
