Re: h2 racer kawayamazuki!
i spent the weekend putting stuff together, took the rims in to get the rubber put on. i hope to have it rolling by the end of the week!
i made these chain sliders yesterday
stopped my my buds place today to use his press and he was busy porting my cylinders. they`re lookin sweet!

question about the swingarm. im guessing its Aluminum. if not, disregard this. are you heat treating after you weld? i heard that aluminum loses some strength during welding. or is it not that much of a factor? it looks like you know what youre doing so i figured id ask.

Awesome build. Why a fuel pump though. That looks like a Mikuni sled pump. They need them because the tank is so low, but yours is normal gravity feed and shouldn't need a pump. BTW if you keep that crankcase pressure operated pump, did you fit 1.5mm float valves? bike float valves flood with a fuel pump..

Re: h2 racer kawayamazuki!
Hey, so here's a quick easy explanation on it. There's a whole internet out there if you want more info. Aluminum will lose up to around 80% of its strength when welded, but will regain back some of that strength over age. If you were to soft anneal a sheet of aluminum making it very malleable and walked away from it for a month, it would be a lot harder then when you had first annealed it, but not as hard as before. The weakest point will generally be the heat affected zone or the area around the weld in the parent/base material being welded. The weld itself is generally not where it will break or i should say shouldn't. If it breaks in the weld then you've probably done something wrong. The majority of TIG welds I see on forums like this are too hot and the rest being too cold. A weld that is too hot will generally be a dull matt grey finish to it. There is a better chance of it cracking and porosity and it will have a bigger heat affected zone, therefore a larger weaker area. A cold weld will have no penetration. The weld will sit high instead of blended in (like toothpaste sitting on top). Your weld will be just stronger than using duct tape or glue!
Welding aluminum PROPERLY takes a lot of bench time and self education. If you think you are a good aluminum welder just because people say that you are, well, you probably have a thing or two to learn. Always educate yourself. I've seen guys that have been welding for 30 years and they couldn't hit the root if their life depended on it, but of course cuz they've been doing for 30 years so they know it all and no room to learn. So much to learn: right filler material and size for job, tungsten selection, technique, machines- transformer vs inverter- that's a whole thing in its self setting wave forms, AC frequency, balance, seperate EP/EN amperages.............
Anyways, I hope that helps. I've been welding in aircraft, military and motorsports for a number of years and as confident of a welder I am always learning and improving. I can say that with the exception of a few clients, the majority of welds i do, do not get heat treated after welding. And the ones that do is because they have had the material annealed for bending and forming then having it brought back to a T6. And when I am sending in my tensile strength test coupons, I don't believe that they are being heat treated before being tested. The information is out there so don't just listen to one person.

Re: h2 racer kawayamazuki!
nice welds are a work of art and good welders are true craftsman...i worked at north west airlines for years and had a several welders do all my g job welding since they did such beautiful work....like yours! thanks for the photos and making me feel inferior. ha
good luck on the project

Re: h2 racer kawayamazuki!
No offense taken. It was a good question as most people don't know. I bet if if people were better educated at this, that half would second guess hopping on their bike, car, aircraft after welding something. Some of the shit I see makes me shake my head and say you fly that how high with those bubblegum/ toothpaste welds?!! Or the chromoly will be all burnt to shit and full of carbon. Yup, there's some scary shit out there.

yer face is gonna be coverd in 2 stroke oil!
