So it runs and the bowls don’t leak! I’m having a little issue with the throttle returning to idle even after a new auxiliary spring was added. Soon I will pull the carbs down and service the main return spring assembly.
I plumbed in a new low pressure (2-3.5psi) fuel pump and a Holley fuel pressure regulator. There is also a splitter block in there to feed the excess back to the tank. Remember that these carbs are built to run on gravity feed and hence really dislike pressure into the bowls.
I make many apologies for the visual and auditory experience of this video:
1) Damn that engine bay is ugly! It’s a work in progress and the carbs have been set up for initial testing and tuning without to much thought towards cleanliness and presentation. This will come as soon as it runs nicely.
2) Canon 7D microphones and controllers suck and I wish I had a better way of getting crisp sound.
I drove it up and down the drive way a bit bit and it definitely needs a tune but it runs fairly nicely and sounds great!

So here it goes… the GP125 is in pieces, the engine is out, the unnecessary road gear is in the bin, clip ons are 3/4 done and I’m studying 2 stroke tuning like a fat kid on a sugar high.
Some reference photos of the engine because I’m yet to see any decent quality ones online:

Thanks Chris for the photos! This was such a fun day, I can’t wait for the next one. Between motorbikes I’ve been getting along with fixing the radiator. I have everything I need, I just need to modify the water outlet to fit the thermo switch and wire that in and we’re good to go.
See Freshly whipped for more of the day. Come on Chris, get some more video up!
What would beeoneoneoh be without a b? I’ve been starring at this photo for quite some time now, you can imagine why.
I’m not going to try and make excuses as to why this hasn’t been my priority for a long time now… but it hasn’t. I have been doing bits and pieces and not posting about it but I’ll do an update at some point. Not a lot of large things to do still, I’m just plugging away at lots of little ones; you know how it is. I thought you’d enjoy the photo, I do, and in due time this car will be better than that^
