the pipeing on the main cage is about 32mm outside wall with about 2.5 - 3mm tubing, its all i could get around here, i wanted seamless T45 but as its not going to be used in compitition i wasnt bothered, all the arms and outside bars are made from 32mm x 1.5mm tubing really light stuff so it will bend if hit to absorbe some of the impact ie trees in a forest.
Did it not crimple any of the bars as it looks like u have a very sevear bend on a few of them....!
Last nite I went to look at a 919cc fireblade engine, measured it all up and it looks like it'll just about fit in so when I get paid I'll go and get it I think. It's been sitting for a year or two so will need to give it a once over and check and oil everything up, there's only 17k on it so should be good enough, will make some difference over the wee 400 engine.
I'll need to see about getting a sprocket for the font with splines to suit the blade shaft and my new 508 x ring chain as I don't want to have to buy them again. Might have to make one up if I can't get one? I'll see when I get to that point
Yea I learned from the first main hoop I tried bending, it just collapsed straight away, so what I do now is don't bend steel on a cold day! If it is keep space heater in front of pipe bender so it just warms pipe slightly, then I shim both sides of the tubing in the die so that it has nowhere to move or start flattening , and it works the best,Quote:

Have the fireblade engine bought, fitted and running, not getting much time at it these days but getting there bit by bit.
I'll get some more pics of it up next time I get back at it, need to get the exhaust made for it which is a bit awkward.
I want videos :D
I'll get videos up when I get it driving, good bit to do to it yet, few things I want to change on it after testing it with the 400cc engine, need to buy some Rose joints and alloy radiator too.Quote:
