Motor problems help

[jerowens]

Hey guys I'm lost here. I recently transplanted my 98 700 rmk into a lightweight chassis. It was running strong prior to transplant. Now that it's in it will run but won't achieve the proper rpm's. With the track in the air I get 5500 on the ground it will crawl at best. I noticed that at idle i'm getting equal pressure from the dual pipes but around 3500 r's the magneto side is dropping off I believe that cylinder is misfiring or not firing period at mid r's. I just did a compression test i'm 110 on both cyclinders on a cold motor. Any ideas or help would be greatly appreciated. Theirs still snow here and I would rather be ridin than wrenchin.

Did you use all the electrics from the 98 motor when you transplanted or did you use them from another motor?

electrics are all from motor. I orginally used the regulator that was on the chassis but was having tach problems. I switched that out and tach is working now.
