So...it'll need another rebuild to replace all the Yambits parts. Seriously why would you NOT use Yamaha seals?

I went thu this on a recent rebuild.
Before I knew better, I bought Shambits crank seals, installed them and buttoned it all up.
Soon after, I read on here how Yamgits seals are crap, so I purchased genuine Yamaha seals in the factory packaging.
I then tore it all apart, only to find .....
THEY WERE THE EXACT SAME FCUKING SEALS!

My concern when i saw the pics was the Mitaka Taiwan pistons... My observations on those are well known on here. yuk!  |

I've had the current set of Mitaka's in my TDR for a few years now with no issues. Cracked a skirt and blew a hole in the last two sets tho  |

Personally I have never had a problem with Yambits and I have lots of other bikes, not just an LC.
I think what we have here is a historical failure of the some parts that has now manifested itself into a general yambits are cr@p. I think that's a bit unfair and if they were supplying cr@p parts they (as anyone) would have gone out of business long ago.
I've bought stuff from numerous suppliers, some has been good and some from those with a good reputation that has been very disappointing (and expensive). You are dealing with a 30 odd year old bike. Even NOS is a bit cr@p as it was designed probably 40 years ago
You pay your money you take your choice.
Back to that engine,
If you believe the guy has built the engine properly then buy it, stick it in your bike and ride it.
If you don't trust him don't buy it and build your own engine.
If your bike sits in the garage/conservatory/glass case and you never ride then you don't need it anyway

My last set of Yamaha seals from Norbo didn't come in Yamaha bags and looked the same as the Yambits ones I took out of my 250LC after they had been in there for around 10 years.

I've bought some Yambits parts for my current 400 build, but nothing for the engine or safety critical. I bought tank mounting rubbers, clock damper rubbers, side panel rubbers, that sort of thing, and they are fine. I did buy a side stand spring and that broke in less than 24 hours, and the bike wasn't even on the stand ! Would have been a problem if the bike was being ridden  Too many stories of parts failures on here and other places to risk things like engine seals for me. If they are now supplying genuine Yam, then that's different, but a lot of their stuff is pattern - certainly all the parts I've had are pattern parts. I only ever use genuine Yamaha parts in an engine rebuild, and when not available, the best pattern I can find, irrespective of whether I intend to ride it or sell it on to someone else. It's a shame Yamaha parts are sooo expensive. I remember when Yam hiked a Ypvs base gasket from a fiver to £30 virtually overnight ! I bought all my parts from Granby's back then, and they were at a loss as to understand why ? Same with the sump bolt gasket - nearly 7 quid for a Yam gasket, under 2 quid for a virtually identical Honda item. It would be nice if Yamaha did a discounted scheme for historic bikes like Suzuki do, but they make too much money out of it to do that. Most of us here probably spend 600-1000 on an engine rebuild, and a lot of that will be Yam parts, so there is a ready market for genuine parts, and that means no discounting  Any engine rebuild has to be taken with a pinch of salt, unless you know the person that built it. I'm sure we've all been caught out with that before - I know I have Dusty  |

I don’t generally like to post negative comments, but in the case of Shambits I’ll make an exception.
I’ve had a few bits from them in the past, and I have to say in fairness some have been alright.
However I (like many others) have had personal experience of the usual suspects. Crank seals and throttle cable.
What’s even worse is their customer service. After hearing about the throttle cables on here I asked them to refund if I returned. They said as I had it over a month they wouldn’t refund. Despite it being unopened in a sealed bag with their logo all over it!
Never bought from them since.

Never even noticed the Mitaka bit, just saw the crank seals and thought "well that's a strip, new gaskets/seals and rebuild" Now here's a thought Not saying this is the scenario but given the way the Chinese knock offs go what if the copied the seals including the markings? Unless it's in a Yam bag I ain't risking it Last LC motor I did came with seals from Grampians and a pattern set from Mutts. Never used either and bought Yam ones Now I know Mutts wouldn't sell crap and Grampians are unlikely to sell inferior ones too The quandary is fitting known good seals or when it's someone else's engine and you say you used pattern seals it casts doubt just like this one for sale I should say one of the pattern seals had identical markings but the other didn't Steve |

Never ever bought from them so cannot comment on their customer experience, however if the can’t get a side stand spring or an actual side stand right (both well documented on here) I wouldn’t trust them. As for engine internals not a chance.

The thing about the crank seals is they can look the same, BUT and its a big BUT, the genuine ones are made by ARS, the pattern ones are made by various companies, SDC, SDA, SFK to name a few.
The key here is to look on the lips of the seals, they need to have a teflon coating on them (red), the stator side seal MUST have the red coating on both lips, the clutch side MUST have the red coating on the inside (crank side) of the seal
Some of the pattern seals (SDA for example), now have the teflon coating and on the correct lips, so they should be fine, but I've never tested or tried them, why bother for the sake of £30
If I get chance I'll take some piccies, I have hundredfs (yes really hundreds) of pattern seals if anybody wants some, since I am moving house and workshop I'll dig them out and put them on the for sale section

Ive said it here plenty of times before, Mitaka pistons are fine, but Ive had issues with poor castings and terrible clean up by the Taiwan guys, so Ive been advising guys to run far away from them for ages. If you can find some not made in Taiwan then you should be ok.
Ive long been a guy who says that Yambits is generally fine and you shouldnt deride them for every part they sell, a lot of it is branded and sold by other folks. I would however avoid the rubber parts, but not their brake hoses as they are UK made and decent.... unlike Legends nasty things.
All this has been said before and can be found by searching.
Im with Dave, I only ever use OEM crank seals... and only if I take them out of the packet. There is way too much crap on ebay thats put into OEM packets that have already been emptied, even used parts in an OEM bag. Thats simply fraud.

Unless it's in a Yam bag I ain't risking it Steve Astute observation IMO.. China has become increasingly adept at Cosmetics. Some of their current Fakes look VERY convincing... as silly example their Fake Blue pills.. currently look to be a better made product than Pfizer s' Real Viagra tablets. Traditionally / historically though, their materials quality is pure Crap.. and evidence suggests that hasn't changed.. even a bit. Possibly ? the end makers are getting better but their Materials suppliers are still heavily cheating... keeping profits up and costs down |

Top ends std bores go for what £5-600 bottom ends half decent without case damage similar amount, parts for a build? That’s going to be £15-1800 I reckon.

They were always cheap performance bikes. That when ridden on B roads would slay a big jap 4.
We thrashed them, trashed them changed them, threw bits away and cut bits off.
That’s why it’s such a surprise that the olive passivate brigade have taken of, and why prices have gone through the roof.
I’d be really interested to know how many present owners actually owned one back in the day.
