Cynic

I don't bother with MPG on my bikes i get enough of it at work in the truck and running a range rover V8 but i know i get a lot more to the gallon now than i did in june FYI at the TT in 2000 i managed to get my GSX down to low 20's to the gallon cos we couldnt get 2 laps in on a tank, and knackerd a back tyre ( from new to knackerd in under 7 days, wore the edges through to the carcas ), happy times...

I know someone who did it the other way round, so i suppose its possible cant see any point mind.

They are vents for the float chambers, our suzukis have the same system OG but ours go over the airbox... Probably a stuck float from where they have been jiggled about fitting them.

A builder and his apprentice on a building site are argueing about how much you can carry in a wheelbarrow. The old guy starts to get fed up with it and says to the younger guy, "Right a months wages! , i bet i can carry something across the site in the wheelbarrow that you can't" The young wipper snapper jumps at the 'easy' money, "you've got a bet old timer, i can lift far more for far longer than you ever can". So they shake on the bet to make it official then the old guy looks at him with a thin smile, "go on then get in......" I'm normally far too late with gags i seem to be the last person to hear them but this had me gigling all day so what the hell.......

Especially the colour......

ouch hope he's OK

I don't know if its me but does anybody else think the new stuff they are laying these days seems worse in wet weather? When i'm at work in the truck if its been raining the thing will spin its wheels very easily, it doesent feel all that good on the bike either (Michelin pilot road 2 if your interested). I thought it was great at first in the 'summer' loads of grip, knee scraping if thats your thing. But now the temperatures are dropping off. I dunno, throw in some leaves and a few myopic car drivers still asleep at half four in the morning and you don't need coffee to get you awake. Comments.......

Its coblers, you can buy a fuel stabiliser if you are not using your bike frequently but as for cleaning the carbs with a little bottle of red stuff Pah. Get yourself a manual (Que OG with the clicky link) and check out the carb, probably something floating around in the float bowl. Hence the intermitance.

If she's done 22k do yourself a favour and decoke it. Sounds posh but when you take the head off have the barrel off as well and then clean off all the carbon from the piston and the exhaust port. Give the exhaust a good seeing to as well if its the original, something stiff like a bamboo garden cane to clear the tubes roughly then leave it overnight with a really strong causic mix, not some daft kitchen cleaner like cilit bang but a proper caustic, you can buy the crystals and make a strong mix. This will clean out the bits you can't get at and will not touch the metal. Give the piston the once over as well checking for scoring and any serious blow past of gasses,(indicated by a dark stain down the sides of the piston). It will be far easier on you and the bike to catch anything like a worn piston early. The little end bearing is also something to check as when they fail their component parts generally end up in the big end bearings and they were never meant to meet. Then you have a few weeks to get the parts/cash together at your leisure if you need anything rather than a big rush cos its siezed in the rain somewhere really awkward (it always is).

Head gaskets are made from copper and are quite critical so i would be buying new ones. Any motorcycle shop will be able to get head gaskets for your bike. You can make the base gasket at the bottom of the barrel from gasket material, cereal boxes are especially good.

Does it smoke? feel excessively hot? using a lot of fuel?? What if you start and go? Any funny/odd noises? need more info. My gut instinct says carb/jet blocked. Personally my bike is warmed up for as long as it takes me to put it into gear, i then keep it 'sensible' for a couple of miles, out of the village seems about right, and thats it.

Get googling, you can buy em brand new. Not from Yamaha in a gold box either. Allens performance was the first one i got to in a couple of minutes, just google Mikuni carbs.

Might want to check the carb slide positions at idle. Cos they are cable opperated carbs they have a cable each,(shock) but there is no common opperating system like on a multi. You cannot adjust the idle at one point and do both cyl. You have to set the idle speed buy adjusting each carb separately. That means you can have the idle screw set high on one carb which gets the engine to tick over after a fasion but the other carb is closed or severly restricted as its set too low, its not the same as balancing the carbs as the slides will sit on the idle screws no matter how well they are balanced. But you are balancing the carbs if you know what i mean. Getting this set right is discribed in the manual and it is a bit of a faf but will cause what you are talking about, at least it did on mine.

You beat me to it OG, if your frame no is 3j0-000101 on, its a G, if its 3j0-000501 on, its a H. If you can put the frame number up we can check for certain, wonder why its a 22? bit odd all on its own when the umpteen other variants have 24.

Basically yes the stroke is the same, the barrel and piston is a straight swap. There are two extra studs in the barrel for the head on the 175 so you will need the coresponding cyl head as well. Dont know about the exhaust, prob a good idea to carry the 175 pipe over as well if you can as it may be a little different inside. The carb will be needed as well, it is the same size and type (Mikuni VM24SS) but the jetting is different. There are some minor differences in the advance range on the cdi settings but its only a degree or so one way or the other. Even all the gear ratio's are the same, even the the final drive. Although the clutch has an extra friction plate in the 175. Hope this helps, the bikes are pretty much identical in most every respect save for cc.

Its under the tank at the front behind the ig coil, look between the frame and the exhaust and you should see it. Gravity and mother earth removed my indicators many years ago with a mild amount of pain on my part but you only truly discover how solid out planet is is by hitting it at speed It was in my days trail riding and she spent more time on her side than upright to be honest, and i've NEVER had any mot issues. Well with the indicators anyway.

Sorry mate if you have milky oil in the gearbox then it wont be the cyl head. It is just a water jacket around the head and barrel nowhere for the gearbox oil to get mixed with the coolant like a 4stroke. It will be the water pump, i had a 350 that did the same filled the box with orrible 'monkey sp#nk' as was the popular dicription at the time and if it gets that bad its lots of meths and patientce to get the bl##dy stuff out. You may get away with an oil change if it was just a bit milky from condensation in the oil from stop start use, but that is prob a bit on the optomistic side.

And the numbers for saturdays draw?? Seriously, there is no 'specific place', round the headstock for maybe a broken wire, and ANY connection could ultimately be the one that lets you down, for my money i would look where you have been. If it WAS working and you have fixed something else and now whatever was working doesent then there are pretty good odds that that is the place to look. I'm not saying that is where the fault lies but its where i'd start and handlebar switches are notorious as they age.

As i have come to understand its to do with the scoots auto gearbox(constant velocity thing) they use a variable belt system (like the CVT in a the mk3 fiesta, Yawn)and the springs nd rollers control how far and how fast the belt moves on the cone to change the ratio. I have to admit i don't have the faintest idea what a variator is but yes i would think some carb changes would be needed for the pipe. Its not like you have bought a two bit exhaust so there should be some tech back and a phone call, or e-mail may be worthwhile otherwise if you REALLY need it for college then the only common sense option is to take it all off till you can be sure whats needed, sorry can't be more help.

The adjuster at the bars is only realy for fine control there should be another adjuster at the gearbox, this has far more effect on things and it sounds like that may help a little. To be honest i think you are just not riding the r6 like an r6 ( i know it sounds daft). Your old cbr will have far more torque relatively speaking and a far shorter 1st gear than the r6, so to pull off smoothly you need to give the yam more revs. It wont hurt it, i suppose its the price you pay for an engine that revs so hard so high....

What they said^^^^^, I have to admit the yam runs on the regular motorcycle stuff and forecourt 2stroke but the suzuki has swam in fresh Rock synth4 every 3-4000miles. At TTS they said as its coolant as well and with the tuning if i want it to last use the best i can afford. Good oil's cheaper than engines. Where's the tesco/halfords brigade with the chip fat.........

What about limiting the number of characters in the bikes section, like with the signatures section. I have to agree with Goff scrolling through miles of bugger all to read the posts does get on the nerves a touch, picture sigs aren't so bad.

Dunno about the mark 7. Had one on my GSX for the last 10years and got 20000miles out of the original c+s. Bloody marvelous things SRJ999 has it right keep it full and get it set right and you are laughing.

I know i've not been on here long myself but let me be the first to welcome you aboard.......

Chris i think that is called experience.......I recon that every person on here that gives usefull advice has more than likely been through exactly the same exp you have. Its how we learn and twirling spanners on YOUR OWN bike connects you with it and is generally very rewarding. If it makes you feel any better with your woes, i have had to sort a puncture(on an 800 mile old tyre ) a siezed rear caliper and now the clutch cable has gone all this weekend so i know how you are feeling.
