is the handlebar switch at fault?

sorry i meant 297mm and yes according to my Haynes manual the 97 year onwards Ace has 287mm length and use 30cc more oil. ive had my springs out last year when changing the oil and measured them, one was at the service limit of 294mm the other a couple of mm longer so i know the sizing is correct. im doubtful about buying YSS springs when they are 15mm shorter. couldnt find any specs for Hagon springs so have contacted the company. the new forks you posted would be nice but way beyond my budget!

has anyone replaced theirs? mine have reached their service limit so looking for some new springs. looking at YSS offering their spring is 15mm shorter than my stock spring, 82mm compared to 97mm. and my year model(1996) is 10mm longer than the rest of the Aces which are 87mm. its all a bit confusing. will YSS be a straight swap even though they are shorter and do i follow the instructions for the 97 year onwards models regarding oil quantities etc?

the bobbins tighten up fully on my swingarm?

back in the day i had a Tzr125. it was restricted to the 12hp learner limit by pegging the powervalve closed. other manufacturers used washers in the exhaust system i believe. to be honest, you are better off leaving the power valve closed. the bikes are a lot more reliable in that state.

i have an original exhaust and i like it

dont know if this is any help to you?- http://www.cartestsoftware.com/fz1/exupmaintenance.html

have you tried emailing Yamaha with your query?

a Thunderace. i went with oem from Yamaha in the end. folks on exup forum have reported problems with EBC stuff.

i have just started to get clutch slip when the bike hits the powerband. the engine is on 34500 miles. so im guessing new friction plates and springs. are the EBC rebuild kits on Ebay good to use or should i go to for oem? not near a Yamaha deal which is annoying.

another ace owner here. just starting to suffer clutch slip in the powerband at 35000 miles. bike is in original condition apart from a longer dogbone to lower the rear end a bit. i suffer from short legs its a black/silver model from 1996. its a comfortable bike i find, apart from the vibes through the handlebars. which are no worse than any other bike ive owned. i can ride for several hours with no issues. the speed is stupid quick to be honest. its fun, but its also a problem when it means very illegal speeds if you want to cane it. seriously thinking of downgrading to a plodder. Royal Enfield continental/classic, is high on my list. i guess my age has a lot to do with it(51). i do love walking into the garage and smelling the fuel/oil bike smell after coming back from a ride.

check the pushrod isnt covered in muck from the chain on the sprocket side. i have heard of this causing an headache for people.

check the chain and clutch adjustment. my bike struggles finding neutral if the chain is slack.

that bike in the pic is only 125cc's?

we welcome, ang heed jimmys advice.
