i just recently replaced my stator and r/r. When i start my bike it runs fine until i put some load on it it seems to bog down and have fluctation on the tach dropping all over the place sometimes dropping 4000 rpm. Once the the bike warms up, the needle on the temp guage moves up to the the first line the bike runs fine with no problems. I have tested the battery with load test and it is fine, tested the coils both primary and secondary side with an ohm meter, readings are what the book says. i have changed plugs and wires checked the length of the spark and i have greater then 1/4 inch. Also have checked all my connection sever times and have found nothing wrong there. Ran seafoam threw a few tanks, I have no clue where to look next and help would be great.
