so what are the benefits of spending 200 of my beer tokens plus the hassle of getting the damn thing fitted cos it looks as though is rustier n tighter than a ginger nuns arse
I guess that the servo noise at start up is the valve closing, so it's default is open!
i ride March through to Nov going to rallies etc every weekend putting approx 200 mile each time, dont thrash it Most of my rides have camping gear on bike and we do 80 mph
but sorting the valve and with it being stuck shut there wasn't so much improvement to notice. And it did not feel like a CB250 with the valve sized that's for sure.
I'm guessing mine is focced as I have no servo noise and just spoken to the previous owner who said he had done nothing to the exup (which means that is at least 6 years and 60k miles - 70k miles and 10 years if the first owner did nothing). I guess if it was like that from when I got it I would know no difference. BUT, I'm not getting any rev counter warning to say the exup is not working. IS there anyway to check without stripping it down? Anyone in Sussex that has a Gen1 with a working exup want to ride my bike to compare?I'm going to start by covering penetrating oil over the bolts for a week or 2. As this will be on the hot pipe, can I use any penetrating oil (I have GT85, 3in1 and WD40 at home)? Is just spraying or covering once a day the way to go? Anything else which may help the bolts come out? I don't mind a mess and autosolling it later.Any links to decent replacement bolts or does anyone know the size?TIA
