toolman Posted December 28, 2009 Report Share Posted December 28, 2009 I have one set up 2 into 1 it is 38 mm (with a 5-1 metering rod) stock stroke milled head 170psi FMF fatties it runs good and is dependable mostly trail riding. I just bought another one 40mm for my other bike I can not read the metering rod numbers on it . It came off of a 250r. Just asking what metering rod are most of you using? Remember trial riding is what i do. I did a search and seen all of the pro's and con's and most only use them for dragging, but i have used one for trail riding for years and love it. The bike I'm putting it on is stock stroke 2 into 1 coolhead 19cc domes 180psi and Pro circuits. thanks Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted December 28, 2009 Report Share Posted December 28, 2009 We run a 38mm on a 7mill cheetah motor. I have no clue what rod is in it right now. I think you are going to be over carbureting it though. the 36mm on the 4 mill ran alot better than when we had the 38mm on it. I have seen results on the dyno with my stock troke, and stock bore motor that indicated anything much more than the 35mm pwk I had on it would have been too big.

toolman Posted December 29, 2009 Author Report Share Posted December 29, 2009 Thanks for the information. But does anyone have any comments on what I actually was asking. What metering rod are you using. I know where your located (elevation) and the type of riding are going to effect what your using. Just thought I would ask.
