Mc 144

[GasGas]

So I have 2 seasons on the 144 over bore from Eric Gore. I can tell you he is a little hit and miss that's for sure. But he will make it right in the end at his expense. But as far as the bike is concerned, I love the 144. I spend a lot of time at the MX tracks with my daughter. She's the fast rider in the family BTW. You can come out of a corner and just roll it on. All kinds of bottom end, and if you do come up a little short on power a little stab of the clutch rewards you with ample power to put you back on the pipe. It does tend to rev up a tad slower but you have more power almost all the way to the top. I would say it's half way between a 125 and a 250 f. Just like riding a 125 but easier. But the real reward comes to the surface when you enter the woods. I would have to say that the 144 is pure magic in the tight single track. I much prefer my 144 to the ec 200. Much more nimble fealing and more than enough bottom. This has to be my favorite bike to ride in the tight woods to date. I've tried all the gasgas bikes in the woods now and this is the best in my opinion. Altough when the trail opens up a bit that ec 450 is like crack.
And on a side note, it's a 2005 and tight as a drum. That makes 5 seasons of hard riding. Out standing build quality in my opinion.

Thank you for the report. I like hearing stuff like this. Though I'd probably disagree on the 450. In the open stuff, there's nothing like the feel of totally wringing out a tiddler. A 125 in the desert is one of the most entertaining experiences a rider can have, so long as you make it sing.

What was involved in the 144 upgrade? Is it more than just an overbore? Eric Gorr did a 240 kit (KDX 200) for my brother in law some years ago, and it was the abomination of desolation! That bike was never right, the head did not mate correctly to the cylinder and it leaked coolant into the bore at first, and Eric did right by him on that, but frankly, the 200 was better in every way.

I popped the top end on my husky 125 about 2 weeks ago ... the jug is on the way out to e gorr for a 144 work over. As far as I know its just an over bore. Hope he gets it right!! quite a few guys w/husky 125's have gone the e gorr 144 route and all seem to be happy. I've heard some less than steller stories about eric tho!! Guess I'll find out in a few weeks .... unless the snow moves in ....

Which piston was used for the GG 144?

There are other, very qualified, people you can send your GG125 cylinder to for an overbore setup; If it was me, I would have Ron at RB-Designs sleeve it and bore it 4mm over stock for you - using the +4mm piston available from wiseco for the YZ125. I would also have Ron blueprint the porting.

I trust very few to touch my motorcycle - the list is very, very short. Ron at RB-Designs and Les at LT-Racing. And now that I think of it, it's funny that one of the few people that Les uses outside of his own shop is Ron...

Ron is the epitome of "perfection and grace"...

We had to clearance the cases for the piston to clear. The head also had to be modified as it sits down in the cylinder about 3/16 of an inch. That is where Eric screwed up as the material he used to build up the head must of expanded and dropped off when it got hot. After that he welded and machined it and it's been fine since. Eric went good for all the repairs after the melt down. He does stand by his word, that's for sure. The plating he uses in the cylinder seems to hold up just fine. Nice looking workmanship when you get your parts back. We usually send our cylinders to a place in Quebec, but I was able to get the over bore, plating and piston kit for the same money from Eric. The Wissco number is 9816M05801. Altough there is another number stamped on the top of the piston aswell. 3063C The other number could be an Eric Gorr number.
