The Piston Broke / Re: Matching engine and frame numbers.
« Last post by meccano on Today at 12:44:21 PM »
I can't answer your question but I bought a YZF750R brand new in 1996 and as far as I can recall that didn't have matching numbers.
That bike got written off at 3 weeks old by a blind old duffer in a car and Norwich Union (now Aviva) supplied me with a brand new YZF on a 'new for old' basis.
That one didn't have matching numbers either, if I remember correctly.
I don't know if it's just me but I've been using Ebay (btw,I rrefuse to stick a capital letter in the middle of a word, even if that is the way they spell it!) since 2003 and every single change they've made to any part of it has made it a little bit worse!

I think nobody gave them the best bit of advice: If it ain't broke, don't fix it!
Thanks mate  8) Glad you liked it!

 :D Very nice Paul stunning needs the seat strip on to look its best, and yes that makes you a full Member,BUT why sell when you have 2 400Fs you could sell  :o
The liners had dropped previously (i spent quite a bit of time making a jig to pull them back up) and i had hoped have the tight fitting spacer as a "shelf" for them to sit on would prevent any reoccurence (i had also grub screwed them under the exhaust port). Speaking to a few 2t gurus over the weekend while helping my mate racing we think it's a possibility that as the liner was blocked in both sides, as it's expanded it's actually lifted the barrel enough to create an air leak between the barrel and spacer. There must be some force there as the aluminium spacers have physical witness marks from the liner impressed in them.

I was on an A road at the time but other than waiting nearly four hours for recovery I'm fine.

Engine will come out in the next week or so and I'll decide my next move. I was really hoping to use it on track at the end of next month and at Donnington in August but that likely won't happen now due to the lead time on getting a set of Yamaha cylinders ported and O-Ringed etc.

Where can you buy genuine Threebond 1104/1104NEO as searches bring mostly America and could it be good to use between the rubber inlet manifolds and barrels as I have dread of them letting in air as they get old,mixture going lean and bang goes the engine. :o

Yes, I have started using the 1104 on the join between the carb/reed rubber, it can be dodgy on used rubbers. Doesn't need much, just a thin bead on the raised ring in the rubber.  The joint with the reed against the cylinder has always seemed good with a new gasket, the gen Yam one noticably thicker than pattern.  Cheers

Yes my 350 was set with a dial guage and the  light system. on box under side panel..tony
I bought a German spec rear mudguard off Ebay a few years ago.  It extended about 2 and half inches below the number plate compared to the UK spec model.  I fitted it on the bike and using a marker pen, compared it to pictures  cut off the surplus.
