2002 GasGas 400 FSE --- battery problem

Hi there!

the guy im seeing has a 2002 GasGas 400 FSE....

Im trying to get it fixed as a suprise for him as right now we are both taking turns riding my bike... and that means we cant go too far!

As far as i know everything runs awsome except we are having an electrical issue... We placed a brand new battery in it not long ago... got 30 min of riding in on it... turned it off... and went to restart it and there was nothing... no power.. nadda... SO this leads me to belive there is a drain somewhere thats causing the bike to run solely off he battery... and not getting any sort of charge!

(i should probably add one of his buddies went to disconnect the headlight.. and was sucessful.. but later plugged it back in... so maybe something FUBAR'd during that process)

So my question is.. has anyone had this problem.... fixed it??

please help!

Thanks so much for your time!

Sorry I'd just check the usual, charge battery, check for power drain then work around the bike looking for it with a multi meter

This is the first generation FSE, and they had a variety of marginal starter system components and thus starter motor speed was often inadequate. All these components were upgraded by 2004 and this is not an issue on the later versions.

Yes, you should check and likely replace the battery. The early models used a #5 battery, this can be replaced by a #7 battery which is the same size but stronger.

Your first generation FSE has the starter motor in front of the cylinder, later versions have the starter motor behind the cylinder. This in itself may not be important, but the later models used a larger starter motor, a more effective automatic compression release, a lower reduction ratio for the starter gears to improve starter motor torque, and a different starter clutch design. I believe that all of these things can be upgraded on the first generation, but the cost could add up.

Another change that can make a big difference, but at a low cost, is changing from the automatic cam chain tensioner to a manual unit, because the automatic tensioners that GasGas used over-tension the chain and make the engine substantially harder to turn over.

Gofasters.com in the U.S. is quite familiar with these issues and you may want to work with a dealer that has early FSE experience.

I have 250 hours on my first generation and I am in the process of rebuilding it, and part of that project includes some additional starter system upgrades.

I should also add that there are fuses under the seat, if you are not even hearing the starter relay click, you should check the fuses and do some multi-meter checks on the starter relay and related wires/connections.

Yeah I agree with what M Stone says, I have the bigger battery, and keep the Starter motor in good shape, Ive sealed it with silicone as best I can and will take it out to clean it inside from time to time. I have the manual CCT and always start with it in neutral rather than on the clutch, that way it always goes. But if it doesnt it just needs a bit of help, give a dab on the kickstart while the motor is spinning ... works a treat!

      I'm thinking of buying a new trails bike as an upgrade from my 12 year old Beta Rev3.

      Looking at the Sherco "standard" 250, the GasGas 250 GT and the Beta 200. Interested in impressions, rants and raves. Thanks

      I've wanted a 300 smoker for a long time, and now I've decided it's the time to do it. I've been already pretty much decided on a 2004-2007 300 EXC, but then I started browsing my local ads and noticed quite a few of these EC 300s for sale. I can get around a 2007-2010 EC 300 for the same money as a 2004-2007 300 EXC, that's why I've been considering it. Does anyone have experience with both of these, preferably these years? It's hard to find head to head comparisons on the internet for these two. Do the EC 300s and pre-2008 EXC 300s have an adjustable power valve? How do the engines and suspension compare? The only thing I've found out from my research is that owners of both seem to love their bikes.

      There isn't many forums talking about trials, and how it is related to offroad riding so I decided to start this thread. When it comes to offroad riding a trials bike (IMO) is pivotal to advancing your skills past the average level and yet there isn't a lot of media expressing this. If you look at the top world riders you'll find over and over that they come from a trials background. I've ridden trials for over 3 years and have seen every bit of the skills transfer over, and most noticeably when I ride trials the day before enduro. Probably the most important skill I've honed is balance. You can spend 30 minutes at the end of your work day riding in your yard, or driveway just to get some training in. I can't even count the amount of times I got on to ride for a short bit, then notice an hours gone flying by! Since then I've noticed the trials riding consistently prepares me mentally for bigger hits on my enduro bike; straight rock faces, gnarly drop ins, mossy stream/rock gardens, all stuff that people consider hard enduro. On top of all that, the trials bike allows me to scope out new areas to make trails in remote spots that some people won't even hike, let alone take a full size bike through. And who doesn't like brand new single track??!

      Got a bunch of parts from a 2001 and 2005 GasGas 300, a 19" Black excel rear wheel, and some 2015 red forks from a Beta 300.  The details are posted on another site and I'm not sure if it's cool to link to that here, so I won't. PM for the link; thanks.

      I'd like to know if a 2000 gasgas ec300 cylinder and piston would work on a 1999 gasgas ec300 bottom end since i cannot find a 99 top end. Any help is appreciated.
