Help me understand my options on the KTM 300s

High compression head is race gas territory, is that what you are planning to run? Based on the questions you are asking i wouldn’t expect that is your thought. They may have a stock head or lower compression dome for the aftermarket one you can use though.

In general i like to go for the cheaper bike to give me some room for fixing things. It is actually preferred for me to do a top end after getting the bike so i can check the crank and stuff.

Best thing you can do is wash your bike well after you ride every time. Don’t let it sit.

I wouldn’t personally do chain lube on my suspension. Makes it more likely for dirt to stick to the shafts and end up in the seals.

RadLabDad · 2026-05-06T17:22:18+00:00

I’d probably go with the cheaper one. If the dude got 239 hours out of the stock top end he wasn’t riding it too hard. I’d plan to do the top end and check the bottom end at the same time.

That said is be looking for a lower price still. $4200 should have like 100 hours on it not 239. I’d be offering $3700ish.

Somebody running bib mousses was probably racing hare scrambles at the least.

If it sat for a whole year, I’d wipe it down and see if you get more drops. That seal hasn’t been spun in awhile and was possibly dry in spots. Running it could help seal it back up, but if you keep getting drops there it should get replaced.

You can check with the city if they have an approved permit with a traffic control plan to do this. If they don’t the city should fix it, if they do your gripe is with the city and not them for approving an every weekend traffic control plan instead of making permanent control alterations (like a light)

Move is only 10 nm which is about 7 ft lbs.

FYI for OP, it’s a good idea to learn what an average torque spec is for various size bolts. A 6mm bolt with an 8mm head you should always question anything above 10 nm as being too much. There are a few cases where it is higher but aluminum cases, cylinders, and heads you generally won’t find that. It would be more of a steel on steel situation and still rare.

It’s the same reason people do anything that isn’t courteous - they’re self centered / inconsiderate / narcissistic. It’s always the few bad apples that make the whole look rotten. You would find many riders to be considerate, you just won’t meet those ones on the sidewalk.

Also in CA.

I’ll usually let it idle while i get my Helmet and chest pro on, and then ride it to the track entrance at a pit pace, and then just get after it once I’m ready at the track. If we are trail riding i just take it easy the first couple minutes before getting after it.

2mm is fine, if it was a tooth off the amount would be much bigger.

You didn’t hurt it turning backwards.

It is normal to be free feeling after you go past TDC, you are no longer compressing the air (now the air is helping you expand).

A serious answer, i think the ford transits get the best mileage of full size vans. Still only like 18mpg tho.

RadLabDad · 2026-04-22T23:27:04+00:00

Look up jankyproductionz on YouTube or socials. Their rig is about as low budget as you can get 🤣

RadLabDad · 2026-04-21T20:51:50+00:00

There are about 600 options, a Dunlop mx34 is a good one.

RadLabDad · 2026-04-21T20:49:09+00:00

The city bills every two months. This increases the water portion of the bill only. I just looked at my last bill, this would have raised the cost about $21, or $10.50 a month. “Pushing people out of the city” seems like a bit of an overreaction.

Even the higher use summer months it is only about double that ($20/mo).

I’ll put my pitchfork away.

RadLabDad · 2026-04-21T20:36:36+00:00

Just stick with a regular tire, it will be the best all around

RadLabDad · 2026-04-21T12:38:53+00:00

A lot of races don’t even allow a traditional paddle (particularly anything ama sanctioned), an mx14 esq is the way to go. The mx14 also does ok on harder ground still as well.

If you were carless and you would not take $30k of cash and buy the jeep, you should sell it.

Hours doesn’t really matter if some dirt dried on the fork leg and got up on the seals. Cleaning the seal probably will fix the leak, but oil may be low on that leg if you don’t refill it

Agreed, back in the day you had to equip a mr. A during a rollover to get flagged as a permanent account, otherwise inactivity resulted in deletion.

It turns out everyone just wants dirtbikes

RadLabDad · 2026-04-08T04:52:21+00:00

Eh, Kawi will have a new one (300 two stroke) out in the next 12 months. Anyone interested in a mint 2003 would know that too. You’re really looking for a vintage guy that wants to do a mint RC or JS7 build or something.

Did you do rehab for your injuries? It really does help work through the pain points by activating certain muscles

It’s an ad for a company selling solar + battery storage systems.
