Finally got my cylinder head back from porting:

I found out where to weld a bung for temp sensor: I also found out that i can't do anything normally or reasonably, now I had a vision of the bike TOTALLY black with apple candy red ... more »

While waiting for parts, i bought some more parts, the hydraulic clutch lever from Magyar is awesome, and the temp gauge is mandatory in my world when you're tuning an engine (also going to use wide band lambda meter while jetting the engine), the power ... more »

That bike will turn out a beauty in white, with that seat cover it will remind of 90's chesterfield factory bikes. Have you checked that the seat will align with the tank? I figured if the mounts are off, maybe the seat will be off now when you have ... more »

Doesn't happen too much in the garage at the moment, still waiting on the cylinder head and a new crank half (old one had worn sprocket). I unboxed the air4orce intake boot i got for about 100$ (New!) it will be interesting to see which one of the runners

Really good looking bike, especially the color combinations

I don't think it's unlikely to be clutch material, depends on the "abuse". nice though that there is an removable screen on KTM. I had to split the cases on my Yz250f to see that the screen was totally packed with dirt. Good luck with the build, will ... more »

Yeah no wonder it was knocking

Ok, did you find the source of the problem? I have read about some issues with this kit, but i will check everything prior to final installation. The cylinder head is away to be ported at the moment, and i have stg 2 hot cams that I will use. Hopefully ... more »

The carillo rod looks so nice, it is a little more expensive but it's nice to know that it probably won't snap.

Flawless, couldn't get any better.

Thanks for making that clear, is it common that it looks like this? I'm not sure about the hours on the bike, but by the look it must be 150-200. I'll give the Yamaha dealer a call and hope it's not to expensive (which it will certainly be)

Started new thread Yz250f crankshaft chain sprocket advice 12/28/2016 2:56 AM

Can i reuse this crank half if i smoothen the teet a bit? I am going to use a new chain and cams, building an 290 engine (I have thread in the build section)

The obvious is to exchange the worn part, but I'm trying to keep the budget

I had the frame and swing arm sandblasted and powder coated, i also did the wheels complete. Went through the spokes first before the sandblast. Thinking about building a new set of wheels later, so didn't want to waste time on

Serious bike you're putting togheter! Sweet that the "Y" part of the frame got above the exhaust outlet, it will look like it came like that from the factory.

Seems to become an solid build, the engine must have had nice top-end power with the cams and the rest? Did you tune the fuel for the mods? I have an faction Mx fuel piggyback tuner lying for your bike if you need, but the shipping from Sweden is probably ... more »

Added reply in a thread Rod kit or crankshaft? 12/27/2016 4:37 AM

If i were in your shoes I would go with the complete crank, it saves time if you don't have the tools or experience. I am doing an complete rebuild myself at the moment, and the only reason i didn't go with an complete crank was that I needed a Carrillo ... more »

I'm sure you already checked, but do all the dowel pins sit tight in place between the cases?

After unboxing the Athena kit i got worried:

Looks like I got an low c/r piston, but part no. says it's 13,5:1. Maybe it's because the combustion chamber in the cylinder head gets relatively small to the bigger cylinder bore, therefore the ... more »
