My GV650 So Far
« on: February 22, 2016, 05:01:05 AM »

Picked up this 2006 GV650 for a song on CL a few months ago.
So far I have:
Replaced the leaky tank with a used one on Ebay
Sortof replaced the broken gauges (the replacement sort of works)
EBC Pads all the way around
Fluids and adjustments
Relocated the fuel pump/deleted the pollution crap
Dechromed some things
Rewired clutch switch to neutral switch

Here is a pic as she sits today:


The next things I want to do are:
Paint (not sure what color scheme)
Trim license plate bracket
Install TrailTech Vapor
Reshape front fender
More dechroming
Rebuild seat to make it more comfy
Add more/better lighting
Upgrade charging/wiring
stuff....

Down the road I would like to swap for a GT650 engine to get a 6 speed and add EFI using the stock throttle bodies and a Microsquirt so I can do some fine tuning.

I love this bike.  Its plenty fast and gets good fuel economy.  I have the feeling I will be keeping her for a long time.

What do you guys think so far?

I reckon you're well on your way.

Besides the 6 speed thing, the EFI has the very important added benefit of being black  ;D

Keep up the good work!

Funny you say that because in my head that's one reason I want to put a gt engine in it.

I figure I'll pick one up on eBay and keep it till this one blows up.  They are a lot easier to come by than the gv engines.

Megasquirt should be pretty straightforward. The only thing is I'll have to either buy yet another new tank or find an external pump that will work and not break the bank.

The cool thing about ms is I will be able to connect a tablet by Bluetooth and use that as my gauge cluster. Which will be pretty much badass.

There is a current project to get a MS working on a Hyo. St present the stumbling block is that there is no cam sensor, only a crank sensor, so it is difficult to distinguish between TDC of compression stroke and TDC of exhaust stroke.

One theory at present is to use the pulse of the MAP sensor to determine intake and this crank phase is known, but it is a work in progress.

Message forum member ertert for details.

I'm not sure why that would be a problem. Microsquirt is designed to handle wasted spark and has been used in many wasted spark applications.

OK now my head hurts. From what I'm reading with wasted spark and dual pickups the phasing should be irrelevant because the ignition will simply fire on both compression and the end of exhaust. And batch firing the injectors takes care of fueling. Hmm.

Wasted spark would work, but plugs/coils would last half as long, for obvious reasons. Injector timing would be the biggest loss though, as you would get condensate forming.

I've faith that ertert will find a way of making things work in what a considerably more efficient way.

The factory ignition is wasted spark so I don't think that would be a problem.   There are many batch fired injector setups as I'm assuming the oem one is.   Since there is no cam sensor there is no way the factory fi could sequential fire.

I messaged him  I'm definitely curious to see where he is with the project.

Factory is not wasted spark and is sequential.

Curious, right? What input did they use to determine phasing? Best guess as I said before is the vacuum reading from the MAP sensor on the front manifold. When the pressure goes low, it's intake stroke and as the pressure starts to increase again, that would be BDC of comp stroke.

Even the carby model isnt wasted spark?
