GSX1150 Rebuild

[ensure]

Its been a couple of years since my last rebuild that i have now sold on so it was time for a new purchase. I bought it about a year ago from a guy who was selling up. It was a case of take it all or nothing. There was an 1150ES (no engine in frame), an 1150EFE (slightly battered) , 3 engines (not complete) , a rolling chassis, spare tank and the ES engine fitted in a motorcross frame. I needed a small truck to get it all home.

A "small" truck to get it all home?
Everybody needs a 100hp 4 cylinder dirt bike!

Wow... that dirt bike appears to have the 1150 frame downtubes grafted onto it. I wonder if hillclimber was the intent.

Many build options with lot's of spares there's enough there to keep you entertained for a few winters.

Fun stuff, Lots of parts to do something with.

Here is the 1150 EFE that came with it. I will deal with that in a separate post

Apparently the bike had been a Beach Racer rather than a motocross

The EFE was last registered on the road in 2002 and the ES in 2010 so there was no guarentees anything was going to work to well. Still it was relatively cheap so worth a shot.
First job was to get the engine out of the yellow frame and give it a health check.

After much angst it came free

Those engines are very heavy so i needed this to move it around.

First job was to get the sump off and check in there. There was about 5mm of sludge sitting in the sump, the consistency of wet Muriwai sand. For those who dont know NZ, Muriwai is a black ironsand beach, very fine sand.
The good news was looking up it looked pretty good.

From what I hear the 1135 engine is getting to be tough to find, so even if you have rebuildable cores, it seems like you're ahead of the game.

A few hours with paint stripper got rid of the orange hue and it looks almost normal now

Next step was to get the valve cover off and see how the top end looks.

[ensure]

It doesn't look too bad but a couple of issues have presented themselves here. 1 spark plug would not come out and 2 of the bolts that hold the cam shaft covers in place snapped off when i was removing them.
Its off to the Engine Reconditioner to get these items fixed.
