I just refuse to pay what people want for used harleys. $5k for a 20yr old sportster, $10k for a big twin, or sometimes you can find a deal for about half that for a bike that needs a rebuild.
 
For the sun, I have one of those geza covers. Very compact and keeps dust and sun off the bike
I'm too lazy to deal with a cover. Plus that would just be one more thing to carry.

In other news I finally fixed my slight oil leak. Turns out it was the starter gear cover. I changed the oil over the weekend and while it was drained I replaced the gasket. I didn't think it was the counter shaft or pushrod seal since it was barely a few drips after a ride. Add in that the chain wasn't flinging it everywhere, and I was guessing the shifter seal, or the gear cover. I had a new gasket for the gear cover, so I started there.
 
Well, ran into a problem. The right fork seal is leaking. The dust seal is definitely dry rotted, so I'm assuming the leaky seal isn't much better. It looks like I'll have to make a tool to disassemble the forks, I refuse to pay $80 for an aluminum 33mm hex key with a hole in it.

Good news is the oem seals and bushings from webike japan are $100 shipped, US parts suppliers it's $180+ shipping. So those are ordered. The big piston forks use 5wt oil so I'll get that from amazon.

How long before you start putting the EFI back on?
 
Well I don't know if my bike placed or not. They were supposed to start announcing winners at 2:30, at 2:50 they were still asking for people's choice ballots. It was hot, I was tired and knew I had a 1hr ride to get home, so I left.
 
Well had a header gasket blow out, the nuts got a little loose and the gasket failed. New gaskets, and since I had the pipes off I added a bung for a wideband. Unfortunately I think my innovate gauge is going bad. It'll read right, the read super lean if you hit a bump, then go back to reading right after another bump. Repeat until it throws a bad sensor code. I'll give it a try with the zeitronix next. down side is no gauge with that one, just a datalog to check after a ride.

do you think it is the guage or the sensor?

Could be either, old sensor went bad on the DRZ, this was an amazon special. But the innovate mtx-l gauges are known for having issues. I've had it for years, and this was the third sensor, 1st started reading way off, 2nd just quit connecting, and this one lasted maybe 10min. I'm going to assume the gauge itself is having issues now, partly because so many others have similar issues. the zeitronix zt2 is pretty nice, if you hook it all up it'll datalog temp, wideband, rpm and throttle position. I'll just do wideband.
 
Ok, the topham style tm34 carbs need a small pilot jet. They come with a 20, I dropped to a 17.5 and it's still rich, so I'm going to try going up on the pilot airjet(don't want to pull the floatbowls again). The needle jet is a little lean so I have a 1 size up coming. Main jet seems good in the mid 12s @70*. Jet needle also seems fine.

In other news I finally fixed my slight oil leak. It was the pushrod seal leaking due to a worn bushing. Didn't want to order a bushing so I made my own with some bearing bronze I had. Now no more drip after running at higher RPM.
