#2102
I used an ascendancy g5 crank and head and ad the internal components from an old grp tuned that I had witch it broke by where the engine mounts goes ,it works great it is virtually the same crank,now I need a rod and bearing since the compression is still very good but I see there are many option and i like to get the best rod for a grp tunned .21? Can anybody help me with this and tell me wich rod is the best for me? Thanks

Hey ambros I was looking up some of the rods for sale on ebay and omnimodels has a duratax rod that look very close to the grp I know the materials may not be as good but for the price I think is worth triying it, the lenght of it is 37.5mm from top to bottom and 30mm from center of the holes the only problem with it is that does not say the size of the holes I will soon take my engine apart to measure the lenght of my rod an if it is the same I will ask omnimodels for the size of the holes,this may be a cheaper way to go even if it will have to be replace sooner. This rod is only 13.0 dollars shipped

The rods have to be the excact same size tho, else you will get timing differences in your engine. The bushings have to be the exact size aswell. For the trouble i'd try and find a GRP tuned, G5, TQ or an TecnoPower B01 rod

Evening guys. Anyone know where to get carb needle o-rings for a Ninja MR21-BO1A? I'm also curious if any of the engines, in the Technopower line up, parts are interchangable (bearings and other internals). Any response appreciated. Thanks!

I know a-main have them but they want 80 for the tecnopower rod thats why I am looking for other options thanks ill let u know I talk to the people at duratrax and they said they will get back with the hole dimensions cause they did not have them at the moment hopefully they come true and they are the same for the money I think is worth trying
