on motogp bikes, what are the arrow buttons on the left clip-on where the head lights, hazards, indicator switches should be?

i keep seeing them on marquez's bike at the end of races

Yamaha says the primary resistance is "3.5~4.8" Ohms

Any 3 ohm coil would do OK

Those bikes are Almost infamous for bad wiring connections causing a cylinder to Intermittently quit running and behave like a Bad or Failing Coil

Might be worth making 100% certain the coil is genuinely Bad.

Dyna Coils are very good stuff,,,but very high priced.
I checked Ebay just for helluva it.

A Seller has a Used Pair of the coils you need,,,Starting Bid is Cheap

$20 + Shipping for the pair.

They are Used,,,,and bidding Could go over $100....2 Risks of buying on Ebay

Dyna coils are NOT Direct-fit,Bolt-On,,,but are "For Bikes" and a Lot easier to install than Car Coils due to size/dimensions

But I thought I'd mention it anyway

--------------------------------------....
Cheapish,,Good ,,Hi Output Coils are Pertronix.
They publish resistance specs,,,making it a bit easier to shop

Just an Example here.***:D

Crotch rockets have more problems than just the seating position. The seats themselves are very uncomfortable, the steering is very sensitive. They are harder to ride, they take more skill and more attention.

What you want is a STANDARD. A Ninja 650 is a standard. So is a Suzuki SV 650. They are fast enough and handle well enough to be a lot of fun, but they're a lot easier to ride and more forgiving for a beginner.

Most standards you either sit straight upright or lean forward just a bit. On some you can adjust the handlebars through a range, and you can get extensions that raise the handlebars or pull them back, to adjust your sitting/leaning position.

There are two schools of thought on what kind of bike you should start on. Some people think the 650 should be your second bike, your first should be a 250 or 300. I don't think a 650 is too big to learn on, so long as you can sit on the bike with both feet flat on the ground.

But we all agree you should start on a used bike, because you're likely to be hard on it. If you buy carefully, after six months or a year you can sell it for about what you paid for it, and THEN go out and buy the new bike of your dreams.

Finally, there is a category of bikes that are meant for occasional off-road. They're called dual-sports or adventure tourers. They are light and simple and they make good first bikes if you're tall enough to 'flatfoot' them. Bikes made for off road usualy have longer suspension travel which makes the seat higher off the ground. But if you're comparing a street bike to a dirt bike, this is the closest they get. 8^)

You need a driver's license for any motor vehicle. For a moped you need a regular car license, or a moped license.

is it overheating? (like running rough or smelling weird or spewing smoke?) .. the temp gauge on my old honda doesn't work at all but the fan comes on and it runs fine so i don't really worry about it .. the thermometer which controls the fan works fine and it doesn't overheat..

you can tell when they start to overheat .. they get super smelly hot and run like crap.. ask my partner about his 1400cc air cooled harley in gridlock ;)

but yeah.. if it's just the temp gauge that's off you can ignore that..
if it's the temperature switch that controls the fan .. that's more of a problem but even then you can just disable the off fucntion and have the fan run all the time.. which is hard on the battery

mind you my bike's old and not worth a whole lot .. i'd rather ride than tinker around needlessly ;)

The Honda 350 was at one time the most popular motorcycle in the US. Back in 70s and 80s you used to see them EVERYWHERE. They came in various styles--street, 'scrambler', enduro--but they were all essentially the same motorcycle, just different stuff on them that changed the look more than the function.

I wanted to buy a used 350 once, back in the 70s. The ads were full of them! I rode one and it vibrated like a paint mixer. I mentioned this to the owner and he said 'Yeah, they all do that!' I didn't believe him, but I rode a couple more 350s and by golly, he was right! I ended up buying a 350/4, the smallest 4-cyl. bike Honda made up to that point, and that was one of the smoothest, sweetest, most reliable bikes I ever owned!

I would say a 350 is just right for a first bike. It's light, easy to manage, etc. But 36 years old is really OLD for a motorcycle! A bike like that could have one problem after another. And parts are not that easy to find, so you end up spending about 1/2 of your time waiting for parts, 1/4 of the time working on the bike, and 1/4 riding. It can really be heartbreaking to fix some expensive, complicated thing and then have something else break 3 days later.

A more modern 250 or 300, like Honda CBR 250/300 or Kawasaki Ninja 250/300, would be a better choice in just about every way. Lighter, more powerful, more comfortable, less fixing required and parts are available just down the street or, at worst, overnight.
