What's everyone's read on the bars, as well as the height. I've never had what could be rally height bars before. Should I lower them back down or try to find a taller seat?

If you want the bar a smidgen lower, try simply rotating it downwards in the clamp. (Then rotate the hand controls upwards so they're all facing you again)

As if you could give me anything except the opposite of validation, oval office.

What I meant is that the bars are kinda high and I'm extremely picky but maybe someone would say "oh yeah all the x bike riders use that height and you get used to it" or "nah man thats way too high for a bar to be, and you need to get on low barring". Or something like that.

But also don't hate me for wanting validation because internet validation is still something and life is hard you know

The best bars are the ones where you don't feel uncomfortable or tired after using them and can operate the bike competently.

FWIW my sherpa had very similar looking fatty bars on it with the associated risers and I preferred it over the factory setup, it felt like I had better control in the fast corners (where it would cheerfully skip and wobble the front wheel when you pushed hard enough) because my forearms would be perfectly horizontal in a crouch.

That’s completely an aesthetic thing but I love the way crossbraces look and can’t bring myself to use fatbars despite them probably being objectively better.

After riding around more these are straight up painful. I shifted them back a bit and it's better, but I'm gonna just put stock height mounts on the bike and bring things back to stock ergos. :( But you make some good points and I appreciate your perspective on this.

I hate the cross brace, and think it clutters things up. Even when I had 7/8 bars on the SV, I removed the cross brace. It's subjective, though, for sure.

ProCycle sells handlebar relocator hardware. Maybe there's something in there that would help. Maybe offset risers?

Figured I'd change the oil in my Grom before the winter gets here and I can't be bothered.

Also swapped out the stock clutch springs/plate for some heavier ones.



Not too much poo poo on the screen but also it's a 125 so how much could it really make.



Stock clutch and oil spinner if anyone was curious about Grom innards.

That's neat! I did want to see that, actually, as I'll have to do it myself sometime. I still think the oil spinner is the worst dumbest thing, and can't understand why honda wouldn't use an oil filter. I'd get a kitaco clutch cover, but I just spent 200 on a seat and 70 on a headlight and 275 on a high output stator and oh god it's bleeding me dry.

The seat is totally worth it and fantastic, though.

The oil spinner works just fine for the highest selling motor vehicle of all time that the grom engine is derived from.

They don't use a filter because the service interval is so short and the engine so low powered that there isn't much to accumulate in the oil to even bother with a filter. Most ~125cc bikes and scooters just have a screen.

I'd be interested to know more about what it's based on, as well as your experience with them. I've heard people at meets say "oh it's based on an old honda engine" but never what it was based on exactly. I also didn't know they brought the oil spinner design over from that.

Intervals are pretty normal at 2500 miles, but they might have been shorter in whatever it was based on.

Slavvy
Dec 11, 2012

It is based on the SOHC super cub/postie but with a normal gearbox instead of the auto slipper 3 speed setup posties have. Locally at least, posties have a service interval of 3,000km but you could easily push that to 4-4.5 and have no issues whatsoever. They're the closest you can get to a corolla with two wheels, I've seen them run with about 100ml of oil and have no issues. It's also something you see on really ancient air cooled traillies that have no power but keep trucking despite the farmer's best efforts.

Basically if the entire engine is running roller bearings you don't actually need oil pressure at all, you just need oil to be present in the vicinity of the bearings. Harley engines are probably the single best example of this as they'll happily run at ~5psi because there isn't a single pressure lubed bearing anywhere. And when they put one in (camshafts on twincam) they got bearing failure like clockwork every 30,000-odd km. The only reason you have high pressure pumps that can't ever be starved is because modern high performance (compared to the 60's) engines have a lot of plain bearings everywhere that can't survive without a pressurised film of oil keeping things from touching eachother.

Fun fact: old husqvarnas had a 4 stroke derived from a 2t bottom end. The oil sump was in the gearbox (separate to the crank case cause 2t) and they had a reverse reed joining the crankcase to the gearbox. Eventually blowby pressure would build up in the crank case and bleed into the gearbox via the reed. Then there was an oil line running from the bottom of the 'box to the head, that slight over-pressure was enough to drive oil uphill and into the head wherein it would trickle back down into the crank-case and the cycle could begin again.

e: and while I'm here why the gently caress not post this which I got to work/on ride recently:



The only difference I could see compared to a modern postie engine is no efi and philips screws instead of 8mm hex for the covers.

The Honda horizontal engines usually have one to get oil to the head, but the bottom end is all splashing all the time.

Lets also remember that Honda horizontal engines are the best selling engine in human history. There are very few engineering gotchas left in those motors.

Can't see it in that image but yes there's also a very small oil pump beneath the spinner. If you do big bore or just want to wheelie all day there are aftermarket ones available, as well as lightweight spinners.

Tonight, I rode 2.5 hours round trip so someone could trade their brand new Seat Concepts Tall/Rally seat for my worn out corbin I got for $125. It's blown my mind in every way. The KTM bend bars and 1inch rise that were uncomfortable the other day just fell perfectly into place with the new seat. My legs are unbent and supremely comfortable, and I can actually grip tank. I love it.

The best part is that I'm sitting on the bike instead of in it, now, and it looks and feels like an agressive enduro while riding. I found myself cornering sumo style on the way home. It's amazing.




Slavvy posted:

This is so fascinating thank you.

Seriously, that was really cool to read. Thanks for elaborating. Ironically I loath how those trail 70s and other monkey bikes look. But clearly they are good machines. I love how every time someone brings up an engine with roller bearings (like the DR), they are like "It needs *some* oil of *eh* consistancy changed at *an* interval, and it will be fine".

Slavvy
Dec 11, 2012

The way I think of it is: your gearbox is running exclusively rollers/low pressure bushes and makes do pretty well with flicking and wicking and it isn't even dedicated gear oil on most bikes, so there's no reason the engine can't do the same.

This also explains why hyosung 250's are able to be a quad cam v-twin with like a 1L oil capacity and still be pretty reliable (QC issues aside). Roller bearing cams.

Also re: monkey bikes, what they have over your grom is those little quick-release knobs at the base of the bars, the bars can swing down so the whole thing can fit in the back of your wagon.

They also have two clutches in one: a centripedal one for taking off/disengaging at a stop, and a multiplate for changing gears. The gear shifter pawl has a second arm sticking out the side which pushes on a roller-style release plate (adjusted by the nut and screw you can see sticking out the side there) so the clutch disengages just before the dogs start moving. It looks horrible when you see it, and it's a oval office to assemble unless you lay the bike on it's side, but it works really really well.



That stamped steel ramping plate in the middle has 3 balls in a cage that sit in the depressions and butt up against the inside of the engine cover, when you change gear the arm turns the plate 1/3rd of a turn and that disengages the clutch. You can see the grom's lineage pretty easily here.

They're not half as good as bib mousse, but as long as you don't puncture a tire in the line of duty you can run down to 4psi. Tire changes are much easier too.

I just set valve clearances on the DR350. Exhaust were in spec, but a little tight (.004, where .003 to .005 is spec). Intake were way loose, .006 and .007, where .002 to .004 is spec. I put them back at .004.

What would cause intakes to get so loose? I thought valves usually tightened themselves over time. What should I expect the next time I ride?
