Hi everyone, I just bought my first bike, an '82 XS400 Maxim. I'm just wondering if anyone has any tips or good-to-know facts about this bike, such as common problems, commonly done upgrades, general comments... whatever Ciao, Eric

Looking for a site which could tell me carb specs for my 82 xs 400j Maxim. Mainly need float level measurement. Looking for any other specs that can be found also for tuning purposes (valve adjustment, etc.) thanks.

I have a 1980 Yamaha XS1100 with a yellow sticker on the side of the block that says BUILT TESTED APPROVED by T G Greencastle Sweden. I cant find any information that traces thsi back to a stock manufacturing sticker, does any one have any information on T G or even what the initials stand for? Any information is greatly appreciated.

Aloha from Hawaii, I have a 1977 Yamaha XS360 Im going to remove the stock air filter and add K&N Pod Filters. I'm going to leave the exhaust system stock. Do I need to rejet the carbs? How do I know I need to rejet? Ive read somewhere that the signs are backfiring, and plug color. Is this right? If I need to rejet, then what are the specs (jets, etc.), settings I need to get near it needs to be running right? The second question is, what do I do with the pipe that ran from the motor to the carbs?it actually attached from the plastic split tube that ran from carbs to engine case. I'm assuming this is the crankcase breather? Now that I'm replacing with po…

I have a 1977 xs360 with a leaky exhaust valve on the left cylinder and I found a good used 1979 xs 400 cylinder head on ebay for $30. I am just wondering if anyone knows if this swap would work for me. If this can't work does anyone know where I could find new valve seals, I am hoping I could pull mine apart and just clean up the valves and seats.

pictorial story so far..... cut rear frame rails and test mounted speedo tried custom tank, but figure its too big, seat is great though bought a DT125 tank and looks better, fitted custom forks which are longer and fitted longer rear shocks bought from stafford bike show last year Cut and welded a Motad exhaust I'm keeping the bars clean I will mount the horn push inside the bar end and fit an ATE BMW master cylinder, so i figure i will need a bespoke tank making now I'm after some flat track type tyres, carbs are brand new from a dohc xs400 and I made new brackets as these were too narrow. swi…

i just bought a 1981 xs400 from a friend she said it ran and it did for a few test rides while i adjusted myself to riding it in the parking lot at my college ( i goto an automotive school so i was having fun with it) i decided to take it home and park it and it decided it wasnt going to start i jumped it using a friends truck. so i figured while it was running id get it home its only 3 miles or so. the bike made it 3/4 the way and died out right wouldnt start. we loaded it in the truck and got it home i took the battery in to charge it and make sure it was good its charged the bike turns over but wont start and now the lights both headlight tail lights and the dash light…

I just became the owner of two classic Yamaha's, 1976 and a 1977 XS500's. I know that they are both point/condenser type ignition systems and I want to convert them to an electronic / CDI set up. Anyone out there know of any set up out there made for this, or that can be made to work?

Hi all, I am new to the site and need a bit of help. I have been offered a XS600 by my a relative. It has not been run for over four years and is belived to have a battery/alternator problem. She can give me no further info and as she lives a considerable distance away, I could do with finding out what the bike is. I.e. is it a sports, a cruiser, a vintage modle or what? Are spares available for this model? Sorry for being so vague. Where can I download a photo? Thanks ChrisK

Dear all, I'm a new user to this club so hello to everybody. Very happy to be part of this community. I have been riding my 2007 Yamaha XT660X for a while now and it rides amazing. However, some time to time bike has a bad habit of cutting off when releasing the trottle. I've read a lot about the common issue with the ECU for these bikes, also I suspect that the problem lies in ECU because after every cut off I need to turn my key on and off for bike to start again. So my question is: If I'd buy a new ECU what difference is between the one with the Orange label (B) and the one with Blue label (P)? Also, if you have a better solution for the problem than cha…

Hi I have just brought a 2008 xt125r of a friend but he's lost the keys so any body got one if so what are you getting out of it and have you modded it in any way or for the experts what can be done to it? cheers.

hi all, new here...... looking for some help if possible. the accelerator on my xt125x (07 plate) has become stiff and hard to twist. after like, 10 minutes my wrist and arm really hurt and become numb. i have tried wd-40ing everything i can see to no avail! any ideas? thanks

alrite guys n girls just lookin 4 a bit of guidance on exhausts 4 a 2007 xt125x. I found that arrow and devil make pipes for them but was just wondering if anyone had any ideas on which is best or if they know of anyone else making pipes for these babys. oh by the way any idea if K&N do an air filter for the xt cheers peeps hope someone can point me in the right direction

xt125x - battery died- when recharged the speedo came on ok but i have tested it in running to discover the speed reading is wrong i.e when am doin 40 it comes up as 30 when doing 60+ it comes up as 48- 53mph- any idea how to fix this myself other than visit a motorcycle auto electrician?

My 2006 xt125x recently has lost power- can only do about 52 mph where i was able to do 68mph a week ago without tearing the ass out of it- maybe i need a new exhaust - devil pipe ??? any suggestions what might be wrong or how to correct the problem? i have no known reason for this decline. Thanks

well i have a xt660x powercomander lying around would it work with my mt-03 ?? as it has the same conections on the throttal body so i was wondering weather it would work as the one for the MT actuly cuts one of the wires where as the xt one is a inline loom

I am new to the owners club. I have a 94 XV1100 the back taillights and blinkers wont work. After getting the bike running the headlight went out. So i jumped a wire to the headlight and back lights everything was fine till I reinstalled the battery case and seat. Then the bikes headlight came back on as normal but the bike will not start again. Any help would be much appreciated Kris

Hi Guys New here so hope I'm in the right place, at the ripe old? age of 62, I have just purchased a xv 125 virago so I'm a born again biker (brought up on the BSA bantam the TRIUMPH cub etc.) "Ace Cafe" blah......blah....blah...... those in the know, know what I'm talking about, back to the xv, I've bought this bike without seeing it and have been told it's a non runner, now I don't expect miracles just looking for a few pointers and opinions, they where supposedly told by a Yamaha dealer (in France) that one cylinder was low on compression, now I would have thought that the bike would start but run lumpy and be gutless when ridden, now that's my opinion, what's yours…

ok. u have a 1987 yamaha virago xv1100. this issue happens mmaybe once or twice a month. The most 4 times a months every.. ill be riding on the highway going pretty fast. for example today i was riding it on the I95 in florida doing about 100 miles per hour for about 80 miles so a good hour drive... i stop at a gas station. turn off my bike.. fill up with some gas. go to start my bike and BAM IT DOESNT START.. When i start it i hear my starter click, so its shooting out and i hear a FAINT spinning. Sometimes if i let it sit for a while it will start right up. Sometimes it wont. 1)If i push start it no problem ( this kills me becuase this is one heavy son of a gu…

hello all, i'm new to the forum and i have a major problem with the carb, the bike struggles to get up to 45mph, and if i hit any head wind i have to gear it down to 3rd and it takes forever to get it to any kind of speed, i got the carb cleaned and the shop owner told me the carb is goosed, is there anything i can do to the carb to salvage it, or has anyone got a good one or know where i could get one, thanks pat
