Yes. Sometimes they do. The early GSX-R750R's had dry clutches, while the normal GSX-R750's had wet clutches. There are conversion kits for lots of bikes too.

Dry clutches have the singular advantage of not being bathed in oil. That means you're not blowing horsepower slinging oil off the clutch. That's also their disadvantage.

Oil bathed clutches wear less. They stay cooler. They are quieter. They have one less oil seal to worry about. Wet clutches rule. :-)

Interesting. So why is it so desirable to be able to slip the clutch on a bike (Either on the track or the street) vs. a car?

less torque so you have to rev higher and slip the clutch more to get going from a stop. i think.

I've seen GSX-R1100s with dry clutches. I don't think it shows gain for most racers, though. Why replace it with a dry clutch when you could put a slipper on there instead?
Dry clutches can be slipper clutches too.

It's desirable to be able to slip the clutch on a car too. Slipping the clutch gives you control over the vehicle at less than idle in first gear speeds. It also lets you soften the blow from gear changes. You just don't do it in cars because their clutches can't take the heat. Literally, they overheat and glaze over. Same can happen on motorcycles, but the oil bath makes that a lot less likely. Slipping the clutch in any vehicle makes it smoother, and easier on passengers, cargo, and tires.

Ya, but typically it's one kit to convert it to slipper and another kit to convert it to dry...just not worthwhile.

Two stroke question.

I've got a bug in my rear end about taking apart my RD. It's pretty much boxes of parts right now but I still have the engine in the frame. I'll probably pull that soon enough. Anyway, I pulled the jugs and heads off to check the pistons which look ok, the right one looks nice, the left is a little charred on the sides, but anyway, while I had the cylinders off I noticed my crank was in a pool of gas. Like literally sitting in a puddle gas up to the top of the crank.

This isn't normal right? It's supposed to be a air/gas mixture. Maybe this is why it was running so rich. How do I go about draining this? Thanks.

For 99.9999999999999% of people out there, dry clutches are a pose-factor thing, due to the noise they make and the "Ooooh spinny things" factor. Hence all the pant leg munching wide-open billet clutch covers for Ducatis.

My RD was the same way, not quite as full, but it had a pool of oil in the crankcase (Check valve in the pump stuck open). I just sucked it out with a vaccuum brake bleeder. If you have a crankcase full of gas, it means that your carbs arent stopping the flow of gas properly, and they just drain into the intake, and then down into the crankcase. Theres no oil in there because it happens when the engine is off, and the pump is not running.

Really, the only time you have to be really concerned is if there is transmission (motor) oil in the crankcase, as that means your crank seals are shot.
Most 2-strokes will start to pool gas if left to idle for a while even. Then you have to rev them pretty good to clear them out.

My bike has been squeaking/squealing terribly the past week or so. It only does it when the wheels are turning so I'm thinking it's either the wheel bearings or something with the brakes. I know squeaky brakes are a common thing, but this sound occurs whether I'm braking, accelerating, or coasting.

It's most noticable when I'm putting around a parking lot and gets quieter the faster I go. Yesterday in traffic it felt like something was holding the bike in place, as I could hold the clutch in on an incline, let off the front and/or rear brake and the bike would sit in place and not roll back like it usually does. When I went to accelerate the back would squat down for a moment, which makes me think the rear brake is sticking somehow. When I get home tonight I'll put it on the centerstand and spin each wheel and let you know if I can isolate the sound. The front brake is a disc, the rear is a drum.

Anything else I should check that could be an easy fix?

How dry is your chain? A really dry chain will sound like a big box of mice squeaking when you are rolling at slow speeds. I'd imagine it still makes noise when you are going faster but the wind and engine noise drown it out.
A really dry/stuck chain would account for the drag as well.

I clean and lube it every couple weeks, so I doubt that's what it is. I think I'm going to take apart the rear drum and make sure everything looks ok and maybe do the same to the front brake. Would a ton of dust in the rear drum cause a squeaking/squealing?

Should I just use more rear brake? Or should I have a look at adjusting my suspension?

This is why comparing insurance rates is nonsense. I have almost the same bike, same age, same company, and I pay five times that. Zip code is a huge factor. My insurance went down about $300 when I moved my bike fifteen miles closer to downtown.

Bike insurance is weird stuff.

When I was looking at bikes last spring, I narrowed it down to 2 bikes, a Buellysses, or a R1150GS. The price was roughly the same and I liked them both, I almost pulled the trigger on the Buellysses but checked the insurance rates first.
Best I found was $800, worst was $1100, full coverage. Full coverage on the GS with Progressive was, and still is, $279. For a 46YO married male with no tickets, no accidents (that I reported) and decent credit. Guess which bike I bought?

That is the lowest price I could get in the province. Yeah, Canadian province. Most insurance companies wouldn't even insure me, and the few that do bikes were sky-high. This is totally normal here. I pay less for my car.

Did you shop around?

I called State Farm to get the same agent as the previous owner, got someone else who then promptly tried to sell me a combo that included life insurance that I didn't need or want. So I said "forget that" and went looking around.

I got a great quote from Kingsway through a Southland Broker and went with them, plus they give discounts for having completed a safety course and being a member of the OMA. Of course, I'm taking about a 28 year old 400cc standard, so as always YMMV.

Location has as much or more to do with rates that driving records it seems like.

In NEPA I paid $75 a year on my 350F. My friend with a two year old Z1000? $75 a year.

In San Diego the best I could do was $400 a year through State Farm for my GS. Same driving record, no new tickets or anything.

I think my battery is dead, but I don't want to buy a new one and find out I was wrong.

I have a Yamaha XT225 which can be a bit hard to start cold sometimes. The other night it cranked and cranked and I just gave up without actually riding it. I'm pretty sure that's probably what drained the battery. I rode it a few days later though, so I didn't think anything of it.

Now when I turn the ignition, not even the neutral light or headlight turn on. I jumped the bike and rode for about 10 miles or so, turned it off, tried to turn it back on... not even the neutral light came on. I push started it and it worked fine but the battery isn't holding a charge.

It's a '94 model and I don't know how old the battery is.

Can I use this oil in my Honda Rebel 250?

http://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil1_Racing_4T_10W-40.aspx

Weight/Viscosity is correct. I have a couple quarts of this and would like to use it. I always used M1 Synthetic in my jeep with good results/luck.

As a side question, are synthetics/partial synthetics often used in motorcycles? I realize that even with cars/trucks most people find regular oil to be just fine with proper oil change frequency. . .

Nope, nothing about energy conserving or anything. Small motor on this bike-- takes less than 2 quarts.

I hear a lot of people saying you need to down shift before you head into a curve. Well my bike (250r) is in 6th gear past 28 mph, well a bit more generally, but that's what the manual tells me. So is it fine that I just stay in 6th all the time unless I need to slow down under 30? I usually lose a couple mph as I enter the curve since I'm letting off the throttle and then gain it back as I power though the curve. This is correct, right?

Oh and isn't it pretty pointless to slow down by downshifting on my bike? If I'm rolling up to a stop sign I generally just hold in the clutch and downshift to 1st and use the brakes to stop. That's after letting off the throttle and coasting down in speed a bit.

Even in slow traffic it's usually at least 35 mph around here, so gears 2-5 don't get much love.

You should definitely be in a lower gear at 30 mph. I go up a gear about every 10 mph or so, so I'd be in 3rd or 4th on my bike. It keeps you in the power band, which is good for quicker maneuvers and more engine braking, should you need it. It's not like your 250 is burning so much fuel that you need to worry about a slight decrease in fuel economy.

Well it doesn't bog down if I have it in 6th gear at 30. According to the manual it's:

Upshift --------- Downshift
1->2 (12) ------ 6->5 (15)
2->3 (15) ------ 5->4 (12)
3->4 (19) ------ 4->3 (09)
4->5 (21) ------ 3->2 (09)
5->6 (28) ------ 2->1 (09)

Just from the sound of the engine I usually shift up a little later. I wait till it changes pitch, otherwise I'd be shifting constantly. It runs fine like that but people keep telling me that I'm shifting too early. Of course my boss is mostly who I talk to about it and he owns a liter bike.

Yeah, you are shifting way too early. I usually am in 3'rd while puttering around at 30mph on my '07 250. Even when I was breaking it in I wasn't keeping my gearing as low as you are.

If you are breaking it in, it's ok to go beyond what the sticker tells you, Kawasaki uses the same RPM's for breaking in an engine for a bike that has a 7k redline and a 13k redline. Just make sure to vary your speeds/rpms on your rides for the first 500-1000 miles.

My Kawasaki 500 cc engine has more torque than yours and I have no power at that low of an RPM. Hell, my car has gobs of torque and would be on the verge of stalling if I tried to accelerate like that. The manual state the minimums; you can safely take it much higher. In fact, you should for your own safety so you can move quickly if you need to.

Like I said, at easy cruising, I take my speed, divide by ten, and that's the gear I should be in at a minimum (3rd gear at 30 mph, etc). When accelerating, I go much, much higher (75 mph in 3rd)
