Splat Shop serve me very well...even being on the other side of ocean.

This is just one place to ride. Below you can have a better feeling of places around

Jitsie sell this tools. Yes, it is overkill for who change bearings of one bike 4-5 times in a decade. But your mechanic has to have one...if not, run away.

My answer is a expanding mandrel. Fit the mandrel in bearing Put the expanding rod from other side Hit it with a hammer The bearing will exit centered. This is important to not enlarge hub hole To fit new one, you will need a tool to keep spacer centered and apply force centered only on external ring

Fan should spin if you short circuit thermostat wires. If not, check AC before and DC after rectifier/regulator (small square black box)

Theres no fill level. When you change oil (around 450cc) it should keep at same level if there no leaks. Cooling system takes around 500cc.

90 psi and turn the part you want to fix red hot with a torch.....use a pressure regulator to maintain pressure constant since it tend to increase when you heat the carbon inside (burn most you can before), use thick gloves, face shield and all proctetive equipment you have since it is something dangerous.

Fixed some dents on pipe using air pressure and heat

Think more or less 100g can't be noted in a blind test...

42 if im right

This tank is from gasgas contact. Other brands you have to use hebo number plate tank.

It will be heavy, more complicated and more expensive...and who cares about fuel economy on a trials bike?

Scorpa has new chassis one year sooner than sherco....keep an eye open for them too

Sherco had new model (chassis) in 2017. They revised clutch too. Now diaphagm like gasgas pro engine. So, it is a more modern product. If this mean better product or not, it rely on personal opinion.

Power (torque) come from engine. It is'nt altered by flywheel. Flywheel is a rotating mass that can store momentum. It has two effects: 1) when engine is comming from a lower RPM to a higer RPM: Engine will increase rpm slower since it has an added mass to accelerate. It can increase traction due a less agressive behavior and it will decrease power burst you have using throttle. 2) When engine is comming from a higer RPM to lower RPM: Flywheel will give energy to system. Rotating momentum can be used to drive the motorcycle. An side efferct is the engine runnig in a more steady way when travelling during a rough terrain like over a bunch of loose rocks or loose terrain. On malleability deppartment, it can increase the "heavy feeling" on motorcycle just like we feel on a big bore engine. Had played with flywhhel a lot and my feeling is: It only good in specific conditions (mud, senior rider, MX bikes on enduro). https://youtu.be/16d-ewfc8lU For average Joe, most of time, better stick with what come from factory.

Grips cutter to convert MX grips in trials ones since it is hard to find in this part of world https://www.flickr.com/photos/cascao/31326703027/in/dateposted-public/

Check coils. Heat can sometimes change ohms reading on defective coils.

Fan skirrel noise and a greath ride scheduled for tomorrow.... Made new motor buschings and it is like new now

This is a very reliable carb. Partly due beeing well sealed from elements. There "O" ring on idle and mixture screws. The weired fitting may be something temporary untill rubber molds itself. Try to find a parts diagram image for this carb to get rid of all doubsts. If everything else fail, look at my video. https://youtu.be/VEWUaVE1y5w

Small video I did. Maybe it can help someone, someday.

Watch carefully factory recomendations (about ratios) since sometimes they care more for emissions (modern) or cold seizure (old) than engine life or cost. Their brand recomendation is another joke. It's a good practice stay on rich side (2%) because we never know when we will find a big uphill mountain road. (And more oil give better ring seal and more HP)

Have seeing it. Brass thread separated from plastic part. It was after trottle stuck open and engine rev to hell

Have done this tire repair kit smaller and light as possible. It fit easily into my hydration backpack. There is a self explanatory video showing the tool on: https://www.flickr.com/photos/cascao/45297539352/in/album-72157660786014720/
