........I have 127 miles on it so far, .........The front brake squeals loudly.......The header pipe is badly discolored near the 02 sensor. ......The engine does not seem to get really hot,......The shifting is very vague and a bit notchy ......
If you mean that shifting must be a well thought action executed with painful accuresse you're right. That is one of the characteristics.The coloration is another one. If you retain the oem muffler with catalisator then there will be another one directly behind it. It will get very hot there with spirited riding after leaving break-in period.I use a chrome polisch to minimise the blueing but I'm not dedicated to remove them, I quite like the grading. Apparantly the best product is Restom ABC4020, produced by Mathys Quality Equipment.
I just found out these engines have a plastic oil pump gear. Anyone ever have one break? It was a broken plastic oil pump gear that destroyed the engine in my '96 Kawasaki Vulcan 1500 classic.
So far I can't recall even one report of the oil pump breaking.
I'm assuming it is a single wall pipe.
Regarding the Royal Enfield's shifting quirks, I decided to remove the stock shift lever and replace it with a heel/toe shift lever to improve the "in" and "out" of gear feel. It may not be everyone's cup of tea, but I personally prefer it on my C5 Military.
