Default 2007 GASGAS 300 EC Rebuild

So it's Winter here not much else to do but drink beer and rebuild bikes so thought I would give the GASGAS a going over. I'm rebuilding the engine and giving the rest of the bike some attention. Thought I would post up some pics for interest. If you have any advise to pass along, please do.

I'll post up a few pics as I get things done.

Wow, you weren't kidding. What would make you go that far into it? 2007 year looks new. High hours? I have yet to dig deep into my 2003 300ec. Have fun and keep the garage warm.

It's interesting what you find when you strip a bike down, I'm really surprised by the weight of the frame they made it to last. The bike had a hum in third gear so thought I would change the bearing in the motor. It's mostly labor so not huge dollars to do it.

Here is a few pics as it goes back together. Frame painted and added some Neoprene to the skidplate and covered the clutch cover in heavy vinyl.

Ya when I looked up bikes with the red frame it sure looks good. Mine is a 2007 with 2010 plastics. I had to alter the air box, can upload some pics on that. You would need to change you subframe I am not sure about the air box to pull it off but so worth it.

Just put it on to keep it looking nice longer, the paint always wares off easy.

Well the engine is all back together thought I would get the squish sorted out since I had 2+mm. Just got he head back today it's pushing 200psi right now guess it should drop a little. I think its sitting at 1.2mm now.

You will need to take a heap out of the chamber. You'll be at 16:1 if you haven't. Read my thread.

The gauge is too crude a tool to tell you anything useful about compression Ratio.

Ideally start by correcting the piston to head angle.
