Just got it firing!
Hi to all readers,
I am doing the conversion from my '95 V75PA into a V75-4V. I am using Lario heads.
I have all the parts I need to do the conversion.
I have found the original V75-4V pistons, but they are 40 grams heavier than the standard V75-2V pistons.
This weight difference might cause vibration issues.
When I look at the part numbers for the crankshaft from the V75-4V and the later crankshaft, I see that they are different (for the V75-4V it is 27064285, for the later 2V models it is 27064185).
Here are my questions:
- Does anyone know what the difference is between the 2 crankshafts (does it have to do with the weight difference of the pistons)?
- Would this weight difference make a big deal, if I use my old crankshaft, without balancing the new combination?
Regards
