A few weeks back on a normal run the 138 started missing and back firing really badly and loudly. To the point it was kangaroo hopping along the highway. I persisted and it seem to come right. I made it home, pulled the dissy cap off and the button inside the cap was gone. Couldn't find it anywhere. I put a new button in but she still had a miss while doing around 35 - 40 mph.
I decided to get the carby rebuilt by procarb. Put it back on and still had that miss. I cracked the shits and took it to a local fella that has had a bit to do with greys and he put a bigger jet in the carby (53) that seemed to improve it but it still has that slight miss and lacking power.
I pulled the dissy out and found the old button so took that out. Put the dissy back in but still not great. (It has the permatrix module so no points)
So it idles perfectly, under slight revs its missing but will rev hard without missing.
Has me stumped.
Anyone have any ideas???
Im thinking finding another dissy and dropping in ??
