2007 GASGAS 300 EC Rebuild

[CanGasser]

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.

frame looks awesome, maybe I should strip mine down, go red with white plastics and decal set. need to know what year plastics would fit, maybe up to 2006, I'm not sure.

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.

What does the vinyl do on the clutch cover?

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.

Here is a little update on my Gasser rebuild, just put a complete YZF front end on and might try the revalve myself. Thinking about using a YZ fender too. Had the rims powder coated. The exhaust didn't seem to want to go back on I must have really hit it harder than I thought, was able to get it back in shape so good for now. I am happy how everything has turned out. With a complete engine rebuild, all the little bits that wear out have been replaced. Squish corrected, air box fixed big plus there. Wheels installed tubeless with some new rubber. Going to try out the new double strip Mitas EF-07 rear tire love the Golden front on this bike.

All in all good winter project can't wait for this snow to melt.

I almost for got, picked up one of the 23oz fly whhels and had some material machined to 15.6oz. So I guess will see if I like it found the bike really good before but thought I would give it a try.

Just realized you are in Ontario only a couple hours from me. Where are you getting Mitas tires? MX1?

Well she is complete took the Gasser out for a small ride the other day. Sure has some punch now. I attached a vid of the first start up.

Just need to work on the jetting from having the head shaved, but I'll sort that out.
