Is it a Light Emitting Diode or incandescent lamp and guessing it has no battery? If it's LED what does your bike have for rectifying the AC produced by the alternator to DC required by a LED? ... + does the fan work as expected? (the fan also operates on DC)

Oil in the coolant means you would also see coolant in the oil and that would almost certainly be the water pump seal. Just a hunch the part number also relates to the dimensions 12.30.7 oil seal

FWIW Montesa from 315R on uses 2 different types of friction materials in their friction plates, a mix of paper and cork apparently alter the friction point. I bought a full set of new plates in 2001 and they are still in the spares box, never managed to kill a clutch. My understanding was that the paper material grabs faster because it takes on less oil then the cork.

Does your fan blow or suck air through the rad ? It's a DC motor so if it spins the wrong direction you have the polarity reversed.

~12 volts D.C. after the regulator ~20 volts A.C. output from the stator

Vinegar Magnesium is highly reactive to it, aluminum is not.

Ordered a Troy Lee 3900 Ultra Armored Top, looks like it covers all the important places. 👍 Thank-you for the well wishes Reggie 😎

You look at the pictures of the special tool Beta would sell to do the job and improvise something that works the same way.

The person that reported the oil hole problem said the symptom included oil never making it to the filter. If your filters get dirty we can assume that is not a problem. All I ever used was Repsol 10w30 as per the manual, it only holds half a litre so I changed it lots. Never had piston problems even after dropping one in the lake.

@bobb so what's the diagnosis, Is she going to live or require surgery?

Anybody have recommendations for something light that protects your ribs some but doesn't cook you? Had a good one yesterday, high sided my TRS onto a parked GasGas solid bar end and a Sherco serrated foot peg. Tired of busting ribs.

Primarily known to drown in deep water crossings.

Never! That would be a formula for complete disaster from the first time you did a wheelie.

My brother added weight to his RL250 crank and when his throttle stuck on in a fall the extra weight twisted the crankshaft, didn't make him ride any better it just cost him a major service. ... most fun ever on a stock TL125 was sneaking up on people in the woods, they were nice and quiet stock.

... and only one field coil so they fibbed about the adding lights part. Extra weight on the crank will lessen the likelihood of a stall but also retards the engines ability to accelerate. Your riding style is what will determine if the heavy flywheel is a desirable modification or counter productive to your riding, when I rode TY250 I found it advantageous to go the opposite way and lighten the flywheel by removing the factory added weight ymmv.

Search for '2013 beta Evo fan switch'. pictures show it to be threaded which only makes sense because there is some pressure there.

So I take it the steel part we see behind the bolts and the paper gasket on one side is a stationary steel spacer ring? We need to see inside to know what they did in there 👍

Pull the cover off and you might be able to tell, you certainly would not want to ride it like that. The OEM flywheel should have part numbers stamped on it and you should be able to see the coils attached to the cover.

It's a Keihin carburetor, go to the Keinin catalogue, Sudco is the biggest supplier of carburetor info and cataloged parts in NorthAmerica ... spark plug looks nice and toasty brown from here even though the important parts are out of focus.

You can rebuild the clutch master with all new parts for about 50 bucks once you identify the model.

It's hydraulic is it not? does it take DOT fluid or mineral oil and did you use the wrong thing or is the master cylinder just seizing from old DOT fluid corrosion? If it was tight at the slave end it would more likely jam on so I would say check the clutch master cylinder plus make sure it's not just tight at the lever pivot.

Half a litre of the transmission oil I use on all my 2-stroke and 4RT transmissions costs about 4 bucks. For about the last decade I have used Kubota branded All season hydraulic excavator oil ISO46 and buy it in a 19 litre pail, that's ~38 oil changes for about 150 (CDN$). For decades before this I used similar products from other farm tractor brand (NewHolland or JohnDeere) and I ride it in sub-zero winter temperatures too with no clutch or transmission issues ever! If you ever have a farm tractor apart you will see almost the same things inside it as a motorcycle. Motorcycles are not considered to be any harder on wet clutch and gear and shifter lubricant or require anything special compared to farm and industrial construction equipment. Except we don't log anywhere near the hours and those machines filter the oil. Your half litre of transmission oil is not filtered and degrades only through the introduction of water, clutch pad material and metal bits in the worst case. The best way to keep your oil good is to change it lots. Consider how much oil changes will cost you buying it at 2.5 times the price plus expensive special shipping for 1 litre and how often will you want to be changing it. Using a relatively cheap and local available lubricant will end up being way better.

It's just gear oil and the chances of it being anything more than a Netherlands company repackaging a product under their name brand is slim to nil. IMO you are going out of your way to pay way more money for something you can buy cheaper and local. The best transmission oil for your 2-stroke engine is the oil you can replace more frequently. If it was truly special it will have a military spec number and that can be used to identify alternative lubricants with the same properties.

I did read your posts 👍 getting as much air off the cinderblock and recovering with complete control is the same motion as the zap, throttle and clutch actions are the same, you are trying to learn the bikes suspension, power and most important control over the bikes attitude in all dimensions in combination with your movements on the bike. If Enduro riding is checkers MotoTrials is chess 😎

The way to become a better rider is to ride with better riders, can't stress that enough. Cement block on level ground and try to get as much air off it as possible, but land it with control so you can add a full lock turn figure 8 over the block 👍 try it you'll like it.
