    kids aren't cleverer, its the crap exam Questions they get and the school system. My kids are in school and even though the schools are in the top 10, they flit from 1 subject to the next and if you don't get it, tough. then there are no winners and losers , just participants. and playing certain games like "tikky it" is banned due to health & safety!! no wonder private schooling is on the up!!! don't know if you saw that programme where the kids did the old O level standards, 2 passed out of 30, enough said
  3. I'd drain the fuel out, put in the best octane in and then thrash the bugger. running an engine for 15mins will only coat the engine in crap, especially if not under load. riding like you stole it, is sometimes the best way to maintain an engine as full bore is the most efficient for an engine. I do this with my bike and car and you can see the crap burning out the back. just my 2p worth

    sounds like a relay. if it persists get it replaced as it will draw a lot of current and will blow your fuse

    sounds like a fuel supply problem, check fuel flow and put an inline filter on. check float bowl height as last resort

    these are the pictures of the xs450 that was on german ebay a couple of years ago i have used google translator and changed the obvious pidgen english remarks; fzr disk and GXR 4 pot caliper contactless CDI ignition system from the Suzuki GSX 400 E was reworked, which is taken directly from the crankshaft end. a new CNC milled housing/cover Yoshimura pistons with 73 mm bore new Yoshimura liners pressed in cylinder head: complete revised with shortened valve stems, worked on and polished , new valves (inlet 36 mm, exhaust 30mm) and with the 38 HP cam shaft

    I'd check with yamaha, as its suprising how much stuff they still have on stock. +.25 is the next step, if you go for +1mm you have no more options, though i did see a conversion to 450cc in germany with opened valves and had to reline the barrels and cut the crancase mouths. i have the pictures and may post if anyone interested!

    well done on getting this far. overboring won't provide extra power only, restore the compression and hence the original power it had. there are a set of .25 overs on ebay at the mo' and you will need to give these to the machine shop so they can match the bores. when I have mine done here in manchester, he marked each piston to bore, so i know he knows his stuff. don't forget they need honing (45' cross hatch) to retain the oil on the bore. when I got my engine finished i read a school of thought that you should use mineral oil and thrash the engine for 20 miles, this breaks in the rings to the bores. it worked for me and i don't burn any oil at all. then you drain the oil and change filter and put in "whatever you use" oil!

    it was easy enough to check the rings when you had the head off!! the carbs spitting back will be the absence of filters as the diaphram in the carb will have trouble lifting properly so making the mix weaker.

    why don't you restrict the gear change quadrant (if the're fitted on modern bikes) just fill in the teeth where you don't want gears. next Q is, what's it for?

    I agree with Yoda, after restoring my bike, the mot tester commeted that they were binding, but after about 100 mile they free'd themselves by bedding in. ie matching the profile of the disk with the angle of the caliper

    you can take the scouser out of liverpool, but you can't take liverpool out of the scouser!!
