My only issues were my own stupidity with this bike.
I tried to start it with clutch held in, in 1st gear.
Oil light came on and I was frantic for about 6 hours.
I changed my oil, oil filter, and my air filter.
Then I popped it in Neutral, and felt very stupid
I bought a 82 XJ650 Maxim used with 17.3k miles. Garage kept for 800, and have had no problems with the bike so far.
The rubber air boot to the carburetors are a bit cracked, so I had a bit of a vacuum issue as far as idling, easily fixed with rubber epoxy.
I also got lucky on a deal for a parts bike. It is an 82 XJ650 Maxim with no title. Engine runs, 17k miles, no front caliper, all for $225. It's gonna be great to have a stock selection of parts in my garage. Can't wait to pick it up!
