2 day old news.....

The bike was back together and seemed to run ok enough that I'm not afraid of the engine. I rode it around the block several times and was pretty happy at the performance after simply bolting everything back together. I had a couple issues. First was a leak at the plastic splitter above the water pump. I guess there's a reason the manual says to use a new O ring. Second issue was one cylinder not firing below a certain rpm. When I put it together I noticed one slow jet was plugged so I opened it up, but maybe the passage in the carb is also clogged. I should also check the air screw settings and see where they are. Third issue is me discovering there should be a washer under the oil pump driveshaft. Fourth issue is a set of leaky forks. I have the seals but haven't ever replaced fork seals before. Fifth issue isn't really an issue but I need to derestrict it as it's pretty much stock except the Tyga GP exhaust.

So now I'm back down to no carbs, no oil pump, and leaky forks. I'm hoping to still get it together for October 3rd, the next trackday at the track where I had lots of fun with the other NSR (yeah, yeah, before it blew up).
