Would love to see some pics of this, and a bit more about it? :-)

Don't worry, these will come. But at the minute it's an engine in a frame on the floor

Here are my engine mounts modified (I didn't do it, but thanks to GIA Engineering in nottingham)

Nice bit of welding, thats the way to go.

Have you thought about the airbox yet?

I was going to just dump pod filters in there, but I'm going to have a look when I comes to fitting them and make a decision then[/url]

I've been busy all week making an adaptor bracket for the aprilia, but the carbs are on the engine, the coils are temporarily in (until I swap them for stick coils to free up some space under the airbox.

Well after 3 week of ignoring the engine in a frame, sat on the floor. I finally decided it's time to make some progress.

I managed to get the frame and engine up onto some forks, refit the swing arm, shock and wheels and make it look like a bike again.

As you can see it's still just a massive jumble of wiring and not even started on the cooling system yet, but having it looking like a bike makes me feel much better about it

Very cool. Streetfighter or YZF stealthfighter?

Going for a stealthfighter

Me too, completely winging it at the moment, not really sure what I'm doing with a lot of it

I tested the electrics last week and they seem to work, now time for the cooling system. Quite obviously I have a thunderace engine, with a 750 chassis. I plan on using the 750 flat radiator (at least for now) but read that you need to also use the 750 oil filter housing. Looking on a thunderace parts diagram online it says that it uses the same oil filter housing as the 750, can anyone shed any light on this?

Also does anyone have a late model YZF750R top yoke they fancy selling to me? I want to use the thunderace ignition barrel but they're slightly different position to the early ones.
