before you start looking for air leaks it could be the slide in the carb stuck if it has a slide i dont know anything about dts you could also try wiggling the throttle cable where it goes into the carb as my yb100 had this problem and it was the throttle cable getting stuck and leaving the slide fully open.

could this be the points set up wrong?

yer i think the points is the only timing on the bike so will do that tomorrow with a feeler gauge thanks drewpy

the cat just wanted to get his paperwork out

anyone have any ideas?

congratz on the news about the baby mate

one of these two would be my dream bike or

Right i have opened my points a bit and my acceleration has got tons better in 2nd gear when i hit 30mph it feels like my bike accelerated quick a bit like a powerband but i dont like it because i think i should of changed gear before wonder if anyone who has had a yb100 could tell me what speed they change gear at and what speed they could get another problem is if i go into 4th it loses all momentum the engine note changes and i slow right down say i change into 4th at 45mph it will go down to 40mph and sort of stay there. all help appreciated hopefully this is my last topic about my bike

could anyone explain to me how to set static timing please?

i was just wondering if anyone could help me with this i was wondering if i can set the dwell angle on my yb100 using this as it only says 4, 6 and 8 cyl? thanks webi

bump

it is blowing from the left hand side of this exhaust where it connect to the rest of the pipe http://www.wemoto.com/bikes/Yamaha/YB_100_E/87-94/picture/Silencer_-_Pattern/

ah right there was some black stuff seeping out of were i know it is blowing from it isnt big but how would i seal it it is where the exhaust system connects onto the down pipe?

last time i looked i know it was running rich because the spark plug was black sooty not oily i took the baffle out today but havent been far enough to see if any improvement can the police do you for riding without a baffle?

yes it has points mine are set at 0.014 i think, i might try 0.012 im also going to clean out the fuel petcock and filter and maybe try it with no baffles where my exhaust attaches to the downpipe sort of thing it is blowing i wonder if that would affect performance?

right my yb100 seems to pull nicely in 1st and 2nd and 3rd in 3rd gear it tops out at 40-45 if i change into 4th it will either stay at the same speed or drop speed i took it to a bike shop and they said it does not need a rebuild so i was just wondering if anyone on here could help also when i am riding it it feels like it hesitates only for like half a second sometimes like you let off the throttle and put it back on quick.

nope i think they are rd wheels but i need to know what year to find another front brake disc

this might help it is a numer that is on the wheel j 18x160 d0t

welcome to the forums sorry i cant help with your problem hope you enjoy your stay

i agree with this totally gas up knows what he is talking about derek i think you need to listen rather than speak if you know what i mean.

hehe derek im only 17 ive had a few near misses on my bike and learned from them i think you should do the same instead of ranting maybe i think everyone is being a bit harsh on him as you do learn by your mistakes id say take the advice from some of the older guys on here as they have been riding alot longer than me or you.

does anyone know what bike the wheels on my bike in my profile are from as i need another disc brake for an mot cheers webi

yes it does but i find it quite confusing

gap is set right i dont know about timing though as i have no idea how to check or alter it

right ill try and explain this the points touch together and then break when the engine is running i see a spark only a little one coming of the points when they are closed.
