I received this message from graham in South Africa but decided to put up my answer here as it may help others in the future. I didnt rebuild my motor but you tend to find the best sources for any parts, especially hard to get things in general. graham: hey grey, im doing a rebuild but having trouble finding parts in south africa, can you tell me where you got your parts for your rebuild please? the parts im mainly looking for is engine parts like pistons,rings,gaskets,bearings(big-end and mains) please if you can help out would appreciate it alot. As a grey import there seems to be plenty of FZR250s in Australia and the UK. Very few seem to have made it to the USA ..... plenty of 400s,600s,750s and 1000s, which can be handy for 'common' parts. http://www.partzilla.com/ When searching eBay use http://www.ebay.com/ or http://www.ebay.co.uk/ or http://www.ebay.com.au The FZX250 Zeal has the same motor (detuned) http://2fiftycc.com/index.php?resources/categories/fzx250-zeal.32/ https://sites.google.com/site/yamahafzx250zeal/parts-list/pistons Ring set.... http://www.ebay.com/itm/FZX250-ZEAL...85?pt=UK_Motorcycle_Parts&hash=item2ec0326781 Gasket...... http://www.ebay.com.au/itm/Yamaha-F...orcycle_Parts_Accessories&hash=item33707db61c http://www.ebay.com.au/itm/YAMAHA-F...orcycle_Parts_Accessories&hash=item43bf49f9f1 Piston...... http://www.ebay.com.au/itm/YAMAHA-F...orcycle_Parts_Accessories&hash=item4d04c959ce http://www.ebay.com/sch/i.html?_trk...+piston&_nkw=fzr250+piston&_sacat=0&_from=R40 Try and cross reference any hard to get parts with other Yamaha machinery ....

thanks grey will go thru it,hopefully this will help, and you can bet i will put a thread up of my rebuild.
hey guys, having difficulties finding these parts, 1hx-11351-00, 3hx-13414-00, 1hx-11181-00, 1hx-11656-00/10/20/30. if anybody can assist me i would appreciate it. im in south africa so if its in your country i dont mind paying postage fees to get the parts.
As far as I know the Zeal engine is identical to the 3LN ...... the 2KR Im not 100% sure about .... internals I think are the same , mounting points to the frame are different.

thanks grey, i worked out the combustion chamber volume and swept volume of the zeal and 2kr, they are identical in numbers, the bore and stroke length on both are 48 by 34.5mm. piston sizes and ring gaps are identical too with tolerences, in my experience of overhauling car engines,if the sum of your swept and combustion volume equels your compression ratio they must be the same. but however this is a motorcycle and i see that the engineering in these engines are very different and more precise. if someone has more info i would appreciate it, dont want to start the build and buy parts then it does not work, i will put up loads of pics in my rebuild thread.
I thought I'd add this info to this thread in case someone is searching for the particular parts mentioned Interestingly doing a quick google search by part number for the carb boots turned up this site http://www.firstclassmotorcycles.com.au/partFinder/fiche/yamaha/1998/fzx25-zeal/intake In their parts lists they have NLA (no longer available) beside the item description for some parts, but there are a lot of parts which at first glance look to be available They also have the cylinder base gasket listed with a price - item 4 http://www.firstclassmotorcycles.com.au/partFinder/fiche/yamaha/1998/fzx25-zeal/cylinder#ficheZone and sump gaskets - item 2 http://www.firstclassmotorcycles.co.../yamaha/1998/fzx25-zeal/oil-cleaner#ficheZone
I'll add these here also https://www.ebay.com.au/itm/For-Yam...old-Boot-Joint-Y3LN-13586-00-BS1/263514569171
Anybody know where to get OEM Viton valve stem seals 3LN-12119 ? $AUD200 from Japan, else $5 Chinese: www.aliexpress.com/item/32882171195.html !!!!
I got some Aliexpress ones recently, I think I went with CBR250 MC22 ones because @Mike Green ended up with some for 4mm valve stems (2KR) when ordering what were supposed to be 3LN (3.5mm stems) Aliexpress if fine, HOWEVER they get their product descriptions mangled at times - it pays to check measurements in the listings as sometimes they throw models together with different actual specifications - e.g. piston rings is another; 2KR oil ring pack is 2mm thick, whereas 3LN is 1.5mm - if they list both models, avoid because there are differences!
Hi, does somedody know where to get the fuel filter tubes inside the tank seperately? The plastic-filter-net is very sensitive and... broken. Thank you!
Ive never seen them sold separately .... maybe buy a cheap petcock from ebay or Aliexpress and remove them Motorcycle Gas Petrol Fuel Tank Switch Tap Petcock Valve Switches For Yamaha PW80/TTR 125/DRZ400/XT250/TW200 Quad Pit Dirt Bike - AliExpress
The double outlet system with separate fuel tap is not common. If the standard part isn't used on any other models and is discontinued, the best option is repair. I am running a vacuum fuel tap from a DRZ400 and left on reserve with fuel pump removed. Sometimes the bike floods. I have one more float needle that needs replacing and hopefully that will solve it. But if not I will have to return to the standard system and fuel tap that has an off position.
Hi guys , what is everyone doing for cam chain tensioners on 3ln fzr ? I think mine is going a bit rattly but I see they are not produced anymore by Yamaha Sent from my 22101316G using Tapatalk
The tensioners are rock solid in my experience. They are a one way ratchet extended by springs. You can buy replacement springs for them and that will make them good as new. Most likely that the cam chain is stretched beyond limits. When this happens, even a fully extended tensioner won't stop it from being noisy. The first FZR cam chain I replaced had stretched by 5mm compared to a new chain, it might not seem like a lot, but it is.
Ah I see it's making a very slight grinding sort of noise on light throttle sounds like chain links rubbing off something or maybe I am incorrect. That may explain being down on power I guess . Where would I get a timing chain even for it do you know ? Sent from my 22101316G using Tapatalk
I should say the bike has about 28k kilometres on it not sure if that would be a reasonable service interval for a chain Sent from my 22101316G using Tapatalk
https://www.ebay.com.au/itm/305320505290 Be aware you need an 'open' style of chain to replace it without splitting the crankcases and accessing the crankshaft. Very hard to believe odometers on grey import bikes (unless it's clean and unmolested), when in doubt, add 100,000km to the reading and it might be close to accurate Also these little 250's are highly strung engines, with all the engineering and complexity of their larger brothers. It stands to reason that the higher RPM's will have an affect on cam chain life, as well as the whole engine in general.
