Lead free solder

[a-teamlambretta]

What are people using to set their squish ?...just bought some 3.25mm diameter lead free solder and it seems a lot less maluable or harder than the full fat lead ...

Cheers Simon.

Plasticene works very well

I've used Blue tack before, but very thin soldering wire (lead free) twisted together seems fine.

3.25mm!!!!!!!!!! how bigs the gap you're checking Si? 2mm should be thick enough

[a-teamlambretta]

Well....it was all that I could get at the time... Anyway it eventually hammered it down to 0.95mm..near enough for me lol

for a 58 stroke bud I'd be looking for 1.1 min

60/110...

Just got 1.3mm on my Avanti 225, using twisted solder held in place by Plumbers Mate

Si, you should be looking @ 1.2mm min to 1.6mm max on a 60mm stroke bud
your piston will tw*t the cyl hd when it heats up & the crank expands

Squish clearance is more related to the conrod length than the stroke. 1% of conrod length is the usual recomendation, but the engine must have perfectly good bearings.

So you need a good selection of conrod lengths to get your squish right
