2003 rm250 squish test

[Taint]

I was wondering if anyone knew the stock squish numbers on my '03 suzuki rm250. I will be shaving the heads and was wondering what the squish is in stock form.

Thanks

I think that they are all a little bit different. I would definately measure where YOUR bike is at before cutting the head. I think that 1.3-1.5 mm is a safe amount.

I use 1/8" solder put it over to the side and kick it one revolution.
The optimum squish is 40-60 thousandths
