Yeah, I'm that broke at the moment I can't even buy new arms haha. I am not impressed with the Bprojects ones, they have a tendency to cross thread very easily. There are still a handful of things that need addressing but it is certainly coming along.
I found someone with a rolling road who will work with me but I'd like to get as close as possible to a tuned engine before I take it to them as they charge heavily.
Not even running the GX race head at the moment so I'm really looking forward to the power figures when it all comes together.
