Project My Fizzer

yeah I found the ebay ones in the UK - those poor fellas get shafted worse than we do on prices.

those partzila prices are totally reasonable, what's their shipping like? Anyone dealt with them?

Average price I could find here was $60 - $80 which is a rort

 

Blair I can't take credit for greys search finds

One of the better ones I found it OZ, part number 30 - that price ain't good either

I have been pondering that very question, I need to pull my carbs again and inspect the seats under a loupe - common sense though tells me, taking a short cut and not replacing the set will come back to bite me later and yet more running issues and disassembly and re-assembly.

for the partzilla price the question is a no brainer, the killer if going to be the wait for shipping...especially at christmas

but you get that...

peace out

 

Hi guy's, just spent the last hour catching up on all above, you've been busy.
Some of it sounds familiar to my 3Ln1, doesn't crack off idle but runs well on the road.
Anyway you both seem to have flooding carbies via the needle & seats, there is a carby specialist that works wonders with Walbro carbs on Racing Karts, http://www.easitune.com.au/index.html
I'd call to see if they can re seat what you've got, good people & not expensive, worth a try.
Also if you find anything in Japanese my translator is happy to keep translating

 

thanks Blair - I did fumble with them initially, got to 3 turns by myself then found a document, perhaps the 3ln1 supplement you posted to be able to differentiate between the inner and outer carbs

 

grey re the mechanics opinion it sounds like as long as there in ok spec carbs are hardy bastards (my old across carbs were disgraceful but still ran ok ) im starting to think more and more our problem may end up being the valve clearance
also i have a 3ln oil sensor thingo you can have it for the cost of postage if you want it

 

Guys just an FYI, I made trip to a local bike shop in search of some needles and querying the lead time on the needle & seat valves. None is stock.
Yamaha Aus. is awaiting an order from Japan due to arrive 10th January, then 5-7 day wait to get to the dealer...

So I ordered them from Partzilla, almost half the price and with any luck less that half the waiting time.

I did try inserting a brass sleeve into the seats, which was an epic fail, all four carbs now overflow, but I knew they were already worn out so I had nothing to lose.

I have another plan with the brass seat inserts I'm going to try in the meantime, but it's merely academic at this stage.
If I do get it to work I'll do a write-up so anyone wanting to keep mobile whilst parts arrive can follow the procedure.

peace out

What were they at prior GI?

 

From 2 if still lean go up in quarter turns or if rich down in quarter turns. I'd wager the former. I have read they are fiddly and quarter turns make all the difference

 

yep hang(ing) idle after revving it means running lean

hop on it and see if you have to give it a handful to get it to pull away from stationary - that's another good indicator of running lean on the idle circuit

peace out
