Hi guys hope someone can advise me. I have a 6 month old majesty 400 on a ride to work in the cold the other day it took on a mind of it's own and when you shut off the throttle an decelerated it was ok down to about 2500 revs about 25mph then ACCELERATED moderatley up to 3000revs then back down to 2500...etc. At other road speeds it seemed ok and at the end of the ride the engine management light lit up just as I arrived at work. It actually climbed the small 50 metre hill outside the workplace on its own!! It behaved the same hot or cold. After work the bike seemed fine with just a littlle hesitancy in decelerating once again at 2500. It seemed to hold it's speed for ab…

Yamaha have set-up a Yard Built dealer contest to promote a bit of healthy competition in their network. Best bit is, many of the parts developed and used on these bikes will soon be available over the counter.

checked into biker metric today and got a mention with me blog. dead chuffed and might inspire more builders to give up and not bother

hi i have a 1988 yamaha yb100 deluxe it seems to go well through the gears but bogs down in 4th this is about when i change gear 1st to 2nd 10-15 mph 2nd to 3rd 25-30 mph 3rd to 4th 40-42 mph i wondered if that seems right to you im also wondering if it could be the baffle as the owner before me cut it down edit:it also stays at around 42-45 mph in 4th no faster edit: just took the bike out for a 40min run when i come back i notice it is idling high and revs are slowly increasing can anyone help?

hi guys i wonder if anyone with a yb100 could help my bike either drops speed in 4th or stays the same this is where i change gear 1st - 2nd 15 mph 2nd - 3rd 30 mph 3rd - 4th 40-45mph and it either stays at 45 or drops back down it seems like it has no pull

Hi there, can anyone help, I have a yamaha yb100 that's not running that good, I have changed points and plug, it ticks over ok but when you pull the throttle it doesn't have any power.

my yb100 just wont seem to go anywhere in 4th it either stays the same speed or like most of the time drop i change from 3rd to 4th at about 40-45mph bought 1 smaller sprocket no difference

hi, i was just wondering if anyone know where i could find an expansion chamber for a 1988 yb100 or would i have to get one made up special like? edit: also what oil do i use to re oil the air filter?

Hi all, first time posting here. I recently bought a YB100 (1980). It is mechanically sound but needs a bit of TLC. In particular, I noticed that the indicator lights do not flash - instead, they just stay lit like a headlight would. I can turn them individually on and off with the switch as normal but they do not flash.All other electrics seem to work fine. In the Haynes manual for the YB100 it mentions a part called the flasher relay, which is supposed to make the indicators flash. So today I took the left hand cover off the bike to see if the relay needed cleaning or replacing. When I looked at the electronics, I found that there appeared to be no flasher relay at all…

hello everyone, i'm getting there gradually with my yb100 but i cant locate a front mudguard, has anyone got any ideas, i have been told they are the same as the fs1e but they are hard to find too, any ideas would be appreciated. cheers alec

hi my yb100 seems to have no power in 4th gear and rattles when i get in top end of each gear bike only reaches 45mph max i can feel the bike rattling throughout the whole bike any help would be appreciated cheers webi

hello i have a 1988 yb100 deluxe model i read a post on here that says the silencer should weigh half a kilo but mine ways nearer 3 kilos just wondered if this is right or not the baffle has also been cut down by the previous owner would this affect performance as i am only getting 40-45 out of this bike i am quite heavy though i weigh about 17-18 stone. all help is apreciated cheers webi

Hi All, I was putting the crankcases together on a YBR125 when I found these 2 halves of a spring on the workbench. I have no idea where they cane from. The spring is still on the gear lever and it's not the kickstarter one. Help please! Thanks Don

Hi all, first time poster here, hoping the good people of the owners club can help me with my problem. I bought my first bike 3 weeks ago. Its an '11 YBR 125. The bike has 200 miles on it I have two questions. Sometimes it is really hard to get the bike into neutral. It either skips neutral and jumps to 2nd or says its in neutral (Light comes on) but jerks forward if I release the clutch. Is this something to worry about? If it is a problem, how do I fix it? Will it go away with more miles? My second question is After I turn the bike off, I hear clicking coming from the engine What is it? Much love to anyone that helps and any…

I've got a YBA 125 Enticer,, the engine rattles and i cant find out what it is, the cam chain is fine. Anyway i've been looking for another engine and have come across a site that says the YBR 125 engine is the same as the one used in my bike,, is this true??. If so, are the mounts in the same place?? and how much can i get one for. Mine is an 03 so would i have to go for one that is nearer my bikes age or will they all fit. Cheers Terry

Hi All, On my YBR 125 the tickover speed is too slow, where do I adjust the tickover? it is a 57 plate and has a carb not fuel injection :-(
