First, as Lineaway suggests, verify the magnetic lanyard is on the killswitch on the handlebar I have owned a 2003 GasGas Pro and currently own a 2015, starting technique is the same for both. When cold: Choke on, have the bike on a stand or leaning on a tree, etc., get on the pegs so you are standing on the bike. Bring the kickstart down until you feel resistance, good smooth forceful kick downward. Kickstart will hit the footpeg. that is normal. Should start 1 or 2 kicks, I sometimes give a short blip of throttle AFTER I hear the bike fire. When hot: same thing but no choke After some time and practice you may get to where you can start it flat foot on the ground. Took me some time to get to that point. I don't know if it matters much, but I run 110 race gas at 80:1 mix, with a high compression head

Place bike in 1st gear, set idle so that the bike will putter around with no throttle input without stalling.

There are many that say that style of rim will always leak and is impossible to seal. Best / Easiest fix is to buy a new rim with the 2 piece turnbuckle style spokes. No rim band, no leaks. I did replace a rim band on a 2003 GasGas more than 5 years ago, it sealed up just fine and had no leaks for years. (I did break off a sprocket mounting tab on the hub.... but that's a story for a different day) Use a lot of patience and soapy water when installing the new rim band, I suggest a band with the valve stem integrated in the band. Thoroughly and meticulously clean the rim before installing the new band. Use rounded tire irons (tire spoons), no sharp edges, to stretch the band into place. Use much soapy water and carefully work the band into the groove in the rim. do not use anything sharp or pointed to push the band into place. the band must fit under the lip in the groove. I used the backside of a dental pick, the rounded portion so the point was sticking up away from the band. Also check out this video from Jim Snell, dude has much experience and knowledge. https://www.youtube.com/watch?v=k290LeBasws

L'épaisseur du pack d'embrayage affectera la difficulté ou la facilité de traction de l'embrayage. La hauteur du "doigt" change à mesure que les plaques s'usent et peut modifier la sensation de traction de l'embrayage. Le pack d'embrayage pour 2004 Pro devrait mesurer 9,75 - 9,85 mm. la hauteur du "doigt" doit mesurer 17mm +/- 1mm. Je pense que la hauteur des "doigts" est plus importante. Le ressort rond doit mesurer entre 4,4 et 4,5 mm d'épaisseur.

Ils sont empilés dans diverses combinaisons pour atteindre l'épaisseur correcte. Exemples en lien ci-dessous. https://www.thehellteam.com/products/engine-parts/clutch-plates/?cn=106&rf=cn À un moment donné, des plaques de pression d'embrayage plus minces (ressorts) pouvaient provenir de fournisseurs de pièces de rechange. Je ne sais pas s'ils sont encore disponibles

I think it would be worthwhile to ensure the passage the actuating rod goes through is clean and clear. To ensure smooth motion.

I am not positive, but I believe they can be removed, and it is a very large torx bit. I don't have one that size, so had no interest in removing them.

I don't know if the Brak-Tec caliper on my GasGas is the same as yours but here goes. I have a 4 piston mono block caliper. I decided to clean the pistons and reassemble I did it one piston at a time. NOTE: I did not remove the large Torx plugs in the caliper. 1. disconnect brake hose from caliper - drain as much brake out of the caliper as you can, some will remain 2. wrap mechanics wire around the 3 pistons you want to stay in the caliper 3. using compressed air "pop" the 4th non-wired piston out 4. At this point I cleaned the piston and reassembled, you would pull the seal out of the caliper with a pick. Lube the new seal (I just use brake fluid), insert new seal. Lube new piston, insert new piston. 5. wrap mechanics wire around the new piston, unwire next piston to be changed. 6. repeat for all 4 pistons.

Yep, that is a better process.

If you come up with a better process for lacing these types of rims, Please share the info.

I recently replaced 7 bent spokes on that style of rim, disassembled, reassembled, etc. Much cursing and swearing, sorry don't have a trick other than patience. but there is a point in the "length" of the spoke where the hub side is past the bend in the spoke but not touching the end stop of the spoke. This allows a little room to slide back and forth a little bit. I did have to do a little forcing to get spokes started in the turnbuckle. I tried to start both spokes in the turnbuckle at the same time, so that one end would not bottom out before the other and have maximum adjustment available. Oh and good luck

Fill gear box with the same transmission fluid that you normally use. Run the bike, get everything warmed up, drain the gearbox right away, refill. repeat until the cloudiness (milkyness) is gone.

let us know how she sounds and congrats on the new bike

I popped the fuel tank off and poked around a bit. I have not owned this bike long or did too much maintenance on it due to multiple injuries. (yes I am making excuses and whining) I did not see any unconnected plugs under the gas tank. There is quite the mess of wires under there. I must have been thinking about the 2003 when I mentioned two plugs not connected. My 2015 was produced prior to KTM buying GasGas, the 2022's are made after KTM bought GasGas. So there is a possibility of differences in wiring etc. Sorry I couldn't help with this part.

You're welcome. I do have a 2015 GasGas 300 Race, the photo I pulled off the interwebs is of a 2022. But they should be very very similar. I purchased mine used, so it was all set up for competition, none of those extra blinkers etc. I will try to remember to look under the tank tomorrow, if I remember correctly there are 2 plugs that are not connected to anything. I will try to confirm.

Just take a second look at the lower triple clamp, throttle side. The 3 parts may have been packaged together for convenience, not necessarily for install location. I have one on my 2015, my previous 2003 had the hole in the clamp and a hole for the bolt but the plate was not installed.
