General Discussion / KTM 300 EXC KYB Forks (NOT VMX)
« on: March 14, 2017, 07:10:18 pm »
Hey all!
This is about a 1997 300 EXC I just picked up, so it's not VMX, but the people here seem to know what they're talking about as opposed to the modern bike forums, who seem to forget about the older bikes the second a new model come see out
My bike has aftermarket suspension, or at least aftermarket Forks. They're USD KYB forks, that are blue anodised (I think?). I can't find any information on them, only one misc post in another forum about 95 CR250 forks
I'm really after info on the forks as they need seals done, so I need to know what seals to get, and fork guards would be nice too
And the shock has a "Drag Specialties" logo on it, but they only seem to sell Harley twin shocks, so maybe the shock was set up by them?
Lastly, does anyone know if the 97 EXC 300 used the red, yellow and green springs in the power valve? Because if it does, I suspect that it's running the red spring judging by the power delivery
Just out seeking some information about this bike, picked it up relatively cheaply (as a swap for a project bike I did up as a holiday project, cost around 800)

Wanted / Re: Wanted: YZ80C/D/E parts
« on: January 16, 2017, 05:05:51 pm »
Thanks Dungar Pilot, but I've already got those parts
And thank you for confirming my suspicions. I'm pretty confident when I say that the previous owner has tried to put bolts in that aren't correct. Fingers crossed he or she hasn't caused any damage
If you know anywhere that I can find some cylinder studs in Australia that would be a massive help. And thanks again for that tip about them

Wanted / Wanted: YZ80C/D/E parts
« on: January 16, 2017, 10:11:30 am »
Hey all!
I'm after anything I can get my hands on for a YZ80C bottom end (Specifically 4 crankcase stud bolts, part number 90116-06139-00. Either from a YZ or TY80 will work)
The special bolts for the YZ80D top end (Part number 90179-06180. Same part from the TY80 will work too). Also on the lookout for a carb (If I can't find one I'll get a eBay replacement)
And anything frame/body wise for a YZ80E. I'm especially in need of lever perches, levers, cables, throttle assembly (If I remember correctly the kill switch was mounted on there? So that would be nice as well)
And any other parts for the any of the bike models mentioned above. If you're selling it I might be looking to buy it!
Yes, I'm pretty much building a mismatching bike intentionally, just because all these parts look like they'll come together as one bike and it is more a learning experience for myself rather than a restoration. I still hope to make it look nice, that's for sure, but it won't be by the book all the way aha
Cheers!

Yeah Evo, as far as I can tell (From looking at exploded diagrams) you've hit the nail on the head. They were only really used on the YZ80 and TY80 around 1976-79 and have been really hard to come buy. I've found a set of 4 on eBay and I'm trying to snaffle them away before anyone else buys them. About $30 for the set plus another $20 in shipping I think

Yamaha / Bottom end is in!
« on: January 15, 2017, 09:18:51 pm »
Howzat!
Got the bottom end just as the sun was going down. Bolted and fitting well (I think??). I didn't think I'd be able to fit the bottom end in using all 3 mounting points, but I got it working, just had to take the foot peg assembly off. I'll have to do something fancy when mounting the foot pegs again but I'll make it work. Just use a really long bolt maybe?
Now to get the engine running haha. I'm sure that the studs/bolts the previous owner used for the cylinder are completely wrong and will need to be replaced. Oh, and the engine is still running standard bore, so I should be able to get it rehoned without worry (Right?)

Put the engine in place and modification will be required. But nothing that seems out of my league. I will need advice on fixing the cracked upper rear mounting point though. Dad suggested just using metal putty and boring a hole through it. I have my doubts that this won't be strong enough though.
Below are some pictures of the engine sitting in place as best as I can fit it
The front lines up really well. But the back is rather problematic. Also, I'm assuming I'll need to get the electrical system from a '76 YZ80C because (And correct me if I'm wrong) the '76 is a points ignition, and the '78 is CDI. It'll be interesting, that's for sure.
P.S: If I'm doing images wrong, can someone please point it out? I have a suspicion I'm doing it wrong. I am hosting on an external site though, so that's right isn't it?

Okay, so i can confirm that it is a 1977 top end (both the head and cylinder have 1T0 marked on them) and I think a 1976 bottom end (It has 598 cast on it, and my searches are coming up as that being the '77 YZ80C)
I didn't even notice my kickstart was welded, I was so consumed in the stud bolts for the cylinder (One is missing and i have a feeling these aren't the right bolts anyway, as the NOS parts on eBay look a lot shorter, same with in the parts diagrams on PartZilla)
I'll try fitting it into the frame today to see how it fits, I'm comfortable doing a little bit of fab work, but not massive amounts. I've been doing that sort of stuff in school (not on bikes, a 1/2 scale plane actually) for about 2 years now so im fairly comfortable and competent with a welder. Same goes without most cutting tools
I'll ask ask Dad if we have a set of vernier calipers to measure the bore
From my knowledge the bottom end seems okay, but is there anything I should be watching out for? I haven't done to much work on bottom ends. What are the signs the bearings are knackered and so forth?
I've googled it but nobody seems to know. Just little flame wars going on over what is right and what is wrong.
Lastly, is CMS a good place to source parts from? They ship to Australia (not cheaply though) and seem to have a much greater stock of parts than all the other sites I've found

I'm located down Gippsland area in Victoria
The local bike shop isn't too keen on me from what I can tell, I worked for him at one point before I knew anything about bikes and got the boot pretty quickly.
How much would I be looking at to get this YZ running? I don't have much in the way of funds yntil i sell my project ZZR, but as much as my Dad insists, I don't want to cut any corners where possible

Yamaha / Update on the engine situation
« on: January 13, 2017, 06:27:15 pm »
Okay so it SEEMS to be that I have a 1978 Cylinder (I'm pretty sure the intake boot as posed to simply bolting on a carburetor is an indicator of this), A 1977 head (1T0 printed into it) and a 1976 Bottom end
My question is, is it even possible to assemble these 3 parts into a single engine that won't explode or otherwise tear itself apart when I eventually start it. I will likely be sourcing a carb from eBay and messing with that because the carb I currently have is in quite rough shape and isn't even complete.
The bore will need some work as it's rusty and just in bad looking shape. Would it be worth sending the whole engine off to TSP and getting them to handle it? I've had good experiences with them on my 01 RM125, but that isn't a vintage bike. Does anyone know if they know their way around vintage engines. That is, if you have to treat them any differently to a modern engine (I'm making an assumption that there must be a few things)
Sorry that I seem to know nothing about this, like I said, I've only been messing with bikes for about two years, and I've never messed with vintage bikes before (Unless you count that TF100 that was my first project)
Thanks rocketfrog for all the pointers, it's been a massive help and will likely help my build along greatly. Luckily I've got two left side covers, one in really good nick and the other...well, it's fair to say it's coped a serious beating

Yamaha / Rebuilding a YZ80E
« on: January 12, 2017, 09:41:02 am »
I need some help guys,
I'm currently in the process of restoring a 1978 YZ 80 (E I think?). But I've got a bit of a mismatch of parts. I've only worked with modern bikes up until this point and never really dabbled too deep into an engine. Now I've been thrown head first into it all with this project. It seems as if I've got a YZ 80 C bottom end and a YZ80 E top end. I'm really not sure how this is going to work, but I've almost got a complete engine and I'm not 100% fussed if I end up with a mild 'Frankenbike' because this is more about learning than getting a bike worth of the title 'Fully Restored'. Any advice at all would be much appreciated, and if I can get help sourcing parts that would be fantastic! I'm probably going to have to rebuild the engine for sure, it's been pulled apart (top end and bottom end separated, although I was told it was one motor running at one stage) so there's slight rust in places like the crank. But everything seems to move really smoothly (I've only moved it by hand a few rotations just to establish if it was cactus or not). So yeah, otherwise I have a most complete rolling frame and hope to have my first running vintage motocross bike relatively soon
Any help would be much appreciated, as I said, this is more a learning tool over anything else, as I've only been messing with bikes for a few years
