Got the brake cable and the Speedometer cable all set in. the Axle is in the wrong direction but i don't think it will matter much. this really shows the powder-coated rims, the cleaned up brake panel, and the new fancy tires. so exciting

This is also the brake light mount i am using. its an integrated tail light with blinkers and all that. 12v LED system. i used a Triumph Street Triple license plate mount as the bracket. i just bent it backwards and it worked out great.

and finally this is the plug for the oil injection which i am striping away and going with the premix. i ordered the plug from Web!ke and it got here quick. i also plugged the screws with standard m6 stainless with copper crush washers to make sure no oil makes it out.

Alright got some photos of the cylinder last night. It came our really nice. its the original GE2 cylinder so in order to get the Vforce3 carbon reed in there i was going to have to get the intake opened up so i might as well have the whole thing ported right! RIGHT!

this is the exhaust ported and smooth looking. no more build up i hope!

and lastly we put the head in a lathe and really smoothed out the top. it feels so nice.

I put the head on last night with my fancy new piston and rings. the piston isnt actually new we just cleaned up the skirt and cleaned the top in the lathe so it looks all nice and new.

I would test fit the gasket on the head to make sure no holes are being restricted. My 2 cents :smile:

That head gasket is weird, why is it like that a design thing or aftermarket?

Agree, seems like the center ring would seal the cylinder but would cause a much weaker seal around water channels. Paper gasket material has a certain amount of squish where the center ring will not unless its a crush-type ring. The torque spec on these head bolts aren't really that much to warrant a crush. Also seems like it covers one "oval" hole and makes it round....hmm :imo:

That's why I suggested a test-fit to the head to ensure no holes are being choked out.

The middle ring is a crsh ring, but it is just odd how they did that.

On the last pic it looks like flow to the head is gonna be restricted by the walls of the cylinder. Maybe its meant to increase water pressure but it seems to be a bad thing but idk.

My guess is the people who designed and made the gasket knew exactly what they were doing, and they measured twice and cut once.... :urban:

Yeah i thought that was strange as well! but the stock gasket that i removed when i taking it apart has the exact same layout of the holes. they turn the oval passages into circles and i am not sure why. very strange to me but i dont really want to start cutting away at the gasket because i feel as though they must have done that for a reason.

Im sure during the design phase they took into account the amount of cooling needed for each area of the cylinder and adjusted the holes accordingly. Opening up a hole bigger would essentially rob the amount of flow from other ports and reduce cooling in those areas. Im on board with assuming Honda did their homework on this and not messing with a factory balanced cooling system. Sick build you have going. Makes my builds look shoddy and thrown together. I like how you put extra time and attention to every part and piece in the process. Leaving no stone unturned makes for longer build times but the final product will be bulletproof. The danm thing will be a rolling work of art when completed!

THANKS! i try to work with every piece of the bike and give each part attention. it really shines through with the hardware i think. thanks for noticing!

its the stock cylinder but i was able to find a two oversize piston on ebay with ring so the cylinder is bored out a little but not to 70cc or anything like that. they do make some really cool aftermarket big bore kits but i thought it would be cool to keep the stock GE2 head. more classic. and with the porting and new reed i am hoping for a nice crisp feel.
