1983 heritage special with 16600 original miles. Bike appears to have been well taken care of but I do not know how long it may have been sitting.. I did not buy it from the previous owner directly... I got it from a private dealer. It seems to run out of breath around 5000 RPM. It will pull to red line but not impressively, and not in 4th or 5th. top speed seems to be about 75 miles an hour and that takes nearly wide open throttle to maintain in fifth gear.TCI seems to work well, all the advance in by around 3,000 RPM. Warm compression 138 PSI dry, 155 PSI after four squirts of oil. Both cylinders exactly the same. Starts easily with enricher on, idles well after it's totally warmed up, but I have not cleaned the carbs or checked the valve clearances yet... They could be tight, I don't know, and it might be starving for fuel on the top-end, I don't know, but pulling some enricher on does not seem to help, it seems to hurt at high RPMs. Timing chain is quiet but I can't really assess its condition because the bike came with fresh oil and a clean strainer. I've only put two rides on it for a total of 50 miles since getting it a few days ago. It's only in the low forties temperature wise, tires and chain are properly aired and adjusted and the bike rolls easily, but I weigh 360 lbs , 6ft 4in, and cut a lot of wind resistance with those buckhorn bars especially. 41 years ago when I was in college I bought a brand new 78 400XS special. I weighed two hundred pounds less but that bike would do a hundred miles an hour reasonably easy, and my friends 650 would leave me behind. I'm a retired engineer that loves projects but I don't want to spend money just for money sake. I forgot to mention it's 17teeth upfront and only 32 in the back. do you think this bike would benefit from re-ringing if the bores measure okay? Are those compression figures good to very good? If a guy did Mike's 750 kit will the original air boxes, carbs and exhaust get along just fine with some simple rejetting or would they hold it back? I just want to be sure she runs as good as she looks but don't I know how much my size is hindering it's giddy up.
