Novarossi conrod length
 
Googled it and nothing surfaced,I need help from someone that has a NR conrod for .12 engines with 14.04mm stroke like the TS1.Can you measure the ID of the pin holes and their depth?Much appreciated guys.

All NR .12 engines have the same conrod, stroke is determined by the crankshaft.

Thanks chopper I thought there were 2 conrods.
I wasn't clear,I don't have NR engine but have a hunch that it's a copy of one and I know that my actual conrod is same length as a NR,25mm so wanted to know those bronze bushings ID so I can swap them.Actual conrod ID's are:bottom 4.50mm and upper 3.00mm if not mistaken.

the MT12 and the CX12 conrod "07600" is 1mm longer

you want the novarossi conrod "07601" fits almost all the new models up until the newer engines like the 3ct and up

07602 is for the 353 2008 version

07604 is for the new 353 and flash and such

The very old engines have a different conrod as said earlier but I just want numbers so I can order or not a compatible conrod.And if someone knows the crankshaft bore of the 11.5 crankshaft that would rock because timing wise I have a beast.

11,5mm crank pin is 4,26mm,pistin pin 3.9mm.

Many thanks Greg,you rock!
Bad news,crank pin is 3.97mm and piston pin is 3.50mm,rod still looks fine so this engine may last a good while.Thank you all very much :)
