Woot woot, a successful day of wrenching!
Alright, so my goal for the day was to set all the floats to spec since I knew I had been messing with one. It ended up being the only one that wasn't to spec, all of the other ones were a couple of millimeters off. I set them as close as I could anyway.
But, on the way of demounting the carbs I found what I believe to be the reason for my issues;
Bear in mind that I have only ridden this bike for perhaps an hour, tops. And it has already collected this much crap in the filter. Obviously the carbs needed a thorough cleaning, which I did.
I also removed the seals for the first time to inspect them, and the PO had used some kind of adhesive which OBVIOUSLY did not like gasoline (I can't understand why he did it, since you can push the seal to fit...).
It's hard to see, but there definitely was some silicone-like crap under all the seals. I can only assume that some of it has gotten dissolved and mixed with the gasoline. I removed all the gunk, without any problem following.
I've never had a more pleasant spot to work on before, I brough the carbs with me and sat in the garage, rather than the basement.
It make a BIG difference of cleaning the carbs (again). Before I really had to rev it when taking off so it wouldn't die, now I could probably have taken off without giving it any throttle at all. It pulled A LOT more in the lower register, and had no "flat spots" throughout the rev curve. Don't know how high I revved it though, as I haven't got a tacho and couldn't hear the engine due to a really crappy helmet (a new one is going to be purchased shortly).
https://vid.me/vymBHere's a video of it idling when hot. A lot better throttle response now as well.
Another thing I noticed now was that it was A LOT harder to start without using the choke (which I obviously didn't connect as it wasn't needed before...). Before it has always started within a second, now it probably took me five or six tries within half a minute to get it going. This makes me assume that it was REALLY rich before, which could explain the fluid in the right hand exhaust. I've got some new spark plugs that I'll install next time I'll take it out to check. I really need to hook up the choke cable though. I don't want it on the steering head, so I'll most likely relocate it, perhaps near the seat lock / oil reservoir. Don't have a choke cable though, so I'll have to look into lengths etc.
There are also some minor adjustments that I need to do, for example there has grown some more slack in the drive chain. Which I find really odd, chains shouldn't really stretch like this should they? It might mean that I didn't tighten the axle enough, but I torqued it to spec... There's also a little bit too much tension in the throttle so it doesn't return all the way as snappy as I would want, I need to help it the last millimeter or so.
Anyway, really happy with this session! The carps are all set to try out Carpy's exhaust once it arrives!
Also, complimentary picture of a chain saw bear I carved when I was younger. It's holding up to the weathers well!
