i was in Valencia for the final round, very good weekend. we were sat in front of a couple of guys from the UK who were telling us how superb the Yamaha V4 sounded, and i had the thought "how can you pick it out from the pack and how much different can it sound?"   then it came round............. it sounds unearthly and unlike any other V4 out there. dont know why tho??!!   looking forward to next year with Razgat on it!
cheers

hi,
if it turns out that the control box is toast (ive had one go after a reg/rect failure) there is a guy in Greece who repairs/modifies them with a switch box to play with the valve timing, i highly recommend him, did a great job on mine.

thanks Mark

but why?!

guys,

a question that i should be able to get my head around, but cant.

if i replace a worn set of ign points with a new set, assuming the points gap is the same, does the ignition timing stay the same??

cheers

guys,

motogp is starting to look more like "the ducati cup";

bring back suzuki, and add bmw.

Lads,

Race day was superb, we were right at the braking point on the finish straight, 350kph right by us, insane.

yamaha did very well in testing on tuesday, Quarteraro second overall and saying that he was very pleased with the new chassis, as was rins. i am hoping for good things in 2025 for them.

who will take it to Marquez next year???

cheers

Excellent season, so it goes to the last round again.
we will drive up the coast and attend at Catalunya, all of the takings are going to the disaster fund so how bad. the weather forecast is good now so crossed fingers for them.

just been cancelled, to be rescheduled for another day another place. they have major problems there, we are there every year and are sitting on four tickets for this year, but their problems are bigger that that.

its a beautiful place.

teazer,

i had thought along these lines with the exhaust, which is a home made attempt at a yz system.
i may well buy a yz exhaust of that era and modify to fit.

many thanks for your input
les.

thanks, i will check both of these out in the coming days, when the rain stops.

thats a good thought, i just wanted to eliminate all of the simple things before spending out on an inner rotor ignition set up as essentially i am happy with the standard cdi ignition, but not if its failing!

folks,

i have a new build finished and have an irregular misfire happening just as it gets to the power band, rev related, not throttle. the misfire is very irregular, like ignition cutting in and out.

the engine is a yz250 cylinder and head grafted onto a dt250 bottom end, all new rebore, crank, brand new carb, correctly set up and jetted, new carbon reeds, intake manifold. also new is the spark plug, cap, coil, cdi box (rex's), the flywheel rotor has been swapped out for one known to be good and the stator plate has been modded to get the correct ignition timing for the yz.  the exhaust has a new silencer and is as new all the way thru.

i just cannot think of anything else but it happens every single time it is ridden. any thoughts will be welcome and thouroughly checked out.

cheers

folks,

in ireland now we have e10 and i premix all of my two strokes, i never have a problem with them starting after sitting all winter (six months here). i also turn off the fuel and let it run down a bit, though not to empty carb as i fear some "cystalisation" might block a jet next time.

i was told that premix will keep an oily film on the surface of the fuel in the tank and stop moisture absorption into the e10, would be nice if it were true!

cheers

hi,

drill and tap a small thread into the post, insert a small bolt with the head reshaped and a hinge pin hole drilled thru it maybe?

its what i would do, but im a proper bodger.

cheers
