Yamaha Workshop

Hi All I have 2007 YBR125 with intermittent starting problems. I turn on ingnition and fuel pump does not prime so engine doesn't start. Have spoken to other users who have same problem so not uncommon. Does anyone know the solution? Wating 15 minutes then throwing water over it doesnt seem practical !!!!! Thanks Martin

Is it worth it ?

I notice that my bike Boggs down at top end with the standard 16:57 set up , I am not trying to get more top end as I know that they aren't designed for 70mph plus , but what I would like is to get more out of each gear and I figure that I would have a wider / more of a power band with the 19 tooth along with just generally more speed / distance in each gear ? Anybody tried this ? Any advice ?

How in the world do I get the starter motor out ? Motor fits like a glove and when the motor is angled it still will not pull out. Now that I have the left motor case cover off, any idea's

How much compression should each cylinder have on a 1986 fzx700? The shop I took to said I am only getting 40psi on each cylinder and it needs new cylinders.He gave an estimate of $1600us.I find this hard to believe,I am not getting any smoke from the exhaust.I took it to be repaired for hard starting when cold.Only would start cold is by push starting.Once started the bike would run fine with lots of power.Would start and run fine while warm,but when cool have to push to start.I figured it would be something with the choke .Help please.I am not sticking another $1600 into it.

Probablys a long shot but does anybody know the standard main jet size for a yamaha aerox yq50? Going to buy of ebay but not sure of the standard size

Got all of the aerox back together went to go for a test ride and there's no power, does not want to move with me on it, but if I lift the back wheel it will spin, could this be the carb setup been wrong, or something else? It did have a 70 kit on before the piston and cylinder went, just fitted a standard 50cc one now tho, any ideas would be much appreciated, desperatly need it fixed

Hi, I have bought old Yamaha SR125 which has not been used for past 10 years. I stripped it down, cleaned, replaced some parts and put back together. Unfortunately it doesn't start. I cleaned carb, checked cables, replaced spark plug, cleaned clutch plates... That was great adventure for a layman girl without a garage, I learned a lot, had some fun, but... Still not starting. With no hope I pushed it to the workshop and I was told that even if I cleaned carb it's still in pretty bad condition and I should replace it. Here's where problem starts. I couldn't find carb for Yamaha SR125 on ebay or in any other online shop. I was told that it doesn't have to be carb especialy…

well finally got the engine back together and dicoverd the oil pump was no good hence the engine goin downhill.. as i stil need use i am going to use premix util i can afford to buy nw parts.. but my question is what ratio of petrol to oil should i use? any help appreciated

Hi there people, I'm looking to re-wire a 1980 yamaha xs 250 and am looking for some info on the very basics of wiring it up. no lights etc, I just want to get the engine running via a kick start [sharedmedia=garage:vehicles:999] . I've got a battery and most of the parts but am just looking for some basic info. Any help would be much appreciated. Cheers, Joe

Hi Everyone When I got this DT to restore, previous owner told me it had seized, so he did rebore with oversize piston and rings. He says it ran for a week and lost compression. But if I feel resistance on the kickstart it seems to have pretty good compression. Could I get some fuel in and try start..or could I cause damage?

ive never setup a bike clutch before i was just wondering on how the plates go?

Got a 2002 xvs 125 with only 8k on the clock but it sat for ages and the tyres don't look their best. Pleanty of tred but a fair few cracks on the side walls. For safteys sake I'm going to change them. What brand would you guys suggest and where have you found the best prices? Cheers, Steph

So, I'm coming here again to ask you all, who have been in touch with Yamaha DT 125. Are someone able to filma a video - how to destruct rev limiter? Because, I did it, but I think that I have not done it properly. My bike still not run freely, and max speed is lower than in start, when I bought my bike (top speed then 120km/h) now max 95km/h, when full trothle in 5th gear (6th has no power). Where else is any limiter in bike what I could do, destruct, eliminate w/o buying something? I have new crankshalf, fully cleaned carb and air filter. No succes. Help me. My bike - yamaha dtx 125 2006. Doma silincer, hgs pipe. Mikumi carb. Stock crankshalf, air filter, c…

Hi, I'm new to the site and wondered if anyone could help me at all. I am restoring/bobbing a 1980 XS250 and am looking for an exhaust. As far as I can tell/know, the XS400 and 250 engines are very similar. Does anyone know if an XS 400 exhaust fit an 250 at all? Also, I'm going to lower the back end from 350mm which is what are on there at the mo to probably 280mm. Are the mounting sizes a universal size or will I have to buy some shocks especially for the XS250? If anyone could help me I would be very greatful. Cheers, it is very much appreciated.

While riding today I tapped the car in front of me with my tire. Immediately after I noticed that ll 3 headlights on my bike were no longer working. I have pulled the main bulb out and it looks fine. Could this have caused me to blow a fuse? Where is the fuse box?

Hi guys, I've got a little problem with my fuel tank cap (on my XJ6). When taking out the screws to change them, my fuel tank cap broke in some place. It's not dramatic per se, but it's not aesthetic! Here's how it looks now: There's no way to glue it, or even weld it; I asked around. My two options were to either change the whole cap, which means I'll have a new key just to the fuel tank, or buy another one and try to dismantle the outer circle from the inner one. So, I bought a second-hand cap. Thing is, I feel like the lock has some problems. When I put the key in it, I can't take it out! I had to take out the cap, and dismantle the locking system to get…

Hi All, I have just bought a new shock online but it does not have the preloader or spring with it. I have taken off the spring but am having trouble getting the preloader off the old shock. Does anyone know how to take it off?

im doin a engine for a friend and come across a few niggles , first, two off the head bolts didnt want to come all the way out without being unscrewed for the last 20 mm,?,,second, one off the bolts had a slit down the lenght of the threaded part ? .im getting new bolts ,,. it was the rocker shafts that had moved into the holes that the bolts go, is this a comman problam, and has anyone seen bolts with slots in , or has this been done by previous owners ,,

i was wondering if anybody knows of anything other than the stock headlight that fits onto the sr? been thinking about a few enduro type ones with the rubber fixings but dont know if it would clear the mounts for the old headlight or knock against the clocks
