Well this weekend started my first tune up, after having so much trouble with starting and running well. All advice received so far, is timing, ignition or fuel related, so I figure it was time to go ahead and do a tune up since I do not know what the previous owner had done. Most items done to date were fixing minor issues, or replacing fluids, now I getting down and dirty and trying to make this baby purr.
On the list:
- Adjust Valves
- Adjust Points Gap
- Adjust Timing
Replace plugs, later date
Bike was still running hard before these maintenance items, and I tested the bike after each procedure. Good news is after messing with the timing plate which wad frozen to the case, I got the timing correct, valves set to .10 & .20 gap, and set the points to .40 gap. The bike is running much better, it actually accelerates well, and seems fairly balanced. When I rebuild the carbs I will adjust the throttle screws per cylinder to get idle right @ 1000 rpm's, since I need to do this anyway during the rebuild.
I'm hoping my carbs are gunky which might explain the hesitations around 4000 rpm's I'm getting. It is not as bad before adjusting the timing.
