Still waiting on my ignition. In the mean time, I've been looking at wideband O2 sensors for tuning. I'd imagine tuning becomes a world easier with one, and for close to the same cost as a dyno tune I can do it all myself.
 
Cool gadget, but how does a driver behind you gauge your deceleration off a system they have never seen or know anything about? In todays electronic world $119 is a bit steep for it. It could probably be made profitably at half the cost.

I'm sure i can find it cheaper somewhere. Save me the time putting in any brake switches so I like it.

You could put one of these in and get the pulsing on deceleration..

I tend to do flick my brakes anyway but I could see the benefit of automating it, as far as adding other patterns I don't see the benefit ATM unless it is adopted by a couple of OEM types.

I'd love to save the money, but based on the description I think you need a brake switch for that to work. Since I'm not running any I don't think it'll fit the bill
 
Bike looks great man. I was looking into one of those accelerometers for brake switches but i cheaped out and went with a $7 stop switch instead ;)
 
Thanks for the kind words guys. Yeah I decided I just didn't want to bother with a switch for brakes, and I liked the idea of the product. I should have the ignition tomorrow, so first start is likely going to be Thursday.
 
Well got the ignition. Didn't realize I needed to get plug caps separate, so can't start til Saturday. Had the opportunity to speak with Paul at c5 ingitions, man what a nice guy. Gave me a ton of information on the ignition system he offers, as well as some excellent jetting advice. Apparently with the triple spark ignition the efficiency of the system is much greater, and combined with the other improvements I made I should expect to have to go a couple of jet sizes larger, hooray for me. He also agreed with my idea to tune via wideband air fuel, take out all the guess work.

So as it sits, everything is done, and once the caps (and colder plugs) get here I will have her started.
 
Everything is good to go, went to change the oil filter before putting oil in it. It is stuck in a way i have never seen before. I stripped it, then drilled it with a reverse bit, got an out tool into it real good, then hooked it up in my 5/8 hammer drill. It smoked the damn drill! Going to torch it tomorrow and see if that does the trick. What a pain in the ass!!
 
I have never had so many delays on a project! Had to grind the bolt out, trashed the housing in the process. I also ordered the oil filter conversion piece to skirt this issue in the future. At this point everything else is done, just waiting for the adapter, which will be here Thursday. The only thing I have not done is change my carb jets for the improved flow/ better ignition system. Paul suggested bumping the pilot 1, and the mains 1 or 2 right off the bat, as well as going to a cooler plug. I think I'll try for an idle first, verify the timing, sync the carbs, then I will go back for the tuning.
 
while I have been waiting for parts this whole time, a 550 I am working on with a friend has really started to take shape:

And we have ignition! She runs real strong, got the carbs synced up all nice like, rejetted as well. I think I may have to go richer still, but at the moment that is a secondary issue. Guess who forgot to change the valve seal when the motor was apart? This guy! I am definitely burning a little oil, and i think its more then just the rings seating. Rather then play a guessing game about it, these engine are not hard to play with, I figure I will lose 2 hours of my life to my idiocy and will have peace of mindividuals in return. So tomorrow I will go back in to take care of it.

Once the deed is done I'll try to get a video up. I took a few already, but the size of HD videos are huge, I'm guessing the best way to upload is through youtube. On a side note, I'm very surprised by how loud this exhaust is. Excellent tone, not too raw, but I'm sure revving it up and working on it will piss off the neighbors! ;D
 
Hagons, always Hagons, lol. Exhaust is MAC 4 into 1. Everything is mostly back together, but I left the head cover off, will retorque everything tomorrow before I button it up. Figure 45 mins til it'll run. FYI there was considerable oil on the exhaust valves when I took it apart. Glad I did it now.
 
All back in working order. Engine is running well, took her around a few streets to get a little shakedown in. ride excellent, I'm very surprised by this little motor, really outdoes what one would expect. I took and few videos, but for some reason there's no sound. will try again tomorrow. As of right now the bike is mechanically done. I plan to ride it around a little, then break it down for all the cosmetic work!
 
So I still need to get a video up I know, but I've been too busy breaking it in. Nice power, loves high rpms, handles extremely well. I need to stiffen the rear suspension up, but otherwise it does everything I want it to. I let a couple of buddies take it for a spin, and they all seemed to have a grin on their face afterwards. Will try to get a video this weekend
 
Haven't had much time, but did get the tank done

And we have powdercoat. Should be able to get it all back together quickly now.
