 I wish I could, but shipping and customs clearance to South Africa is a nightmare. Might end up paying double the part`s price.

If the black strips are hard rubber then Johnny could be right - the side guides off a slipper. Have you had them both out to check? Perhaps post some photos of them so that we can compare with good examples?

The wear marks on the crankcase seem to show that some sideways movement on the cam chain has allowed it to rub against it.

Are the metal bits aluminium or steel (magnetic)?

I think it may become clearer when you get further into the strip down.

PS It will all be OK

I found this pic on one of your olders posts, 

Looking where the red arrow is pointing, is that a Lip or a edge that the Chain Slipper should push against? Cant really see, and my casing is worn, so im not sure if i should have it or not? 

 

 

Just got some bad news from the dealer. Lead time for a new slider is 6 weeks.

How soon can total ttr supply one to south Africa? And price? Should I order via their website?

Not sure what the earlier photo showed but there isn't any sort of raised lip on the casting I just looked at. See photo below.

I can't think why the slippers should have been damaged in that way unless there was more end float on the camshafts than there should be.

Did the cams and cam caps look OK - does it look as if either or both of the camshaft sprockets might have worked loose at some stage?

Brian

PS Was the metal swarf magnetic?

 It just looked on the first picture that there is a lip, Might just be the angle or oil on my glasses.  Im just relieved that there shouldnt be a lip.  Cam caps, NO, the exhaust side is NOT OK, wil post a picture later today, dont have one with me now. Looks like it was mutilated and patches up with with some resin kind of goo. 

Cam gears 100%

Regarding the swarf, no, it wasnt magnetic. so i can rule out worn crank or bearing right? 

The oil filter collected most of the swarf. 

 

You are right Steve, the SA post office is a no go. I've placed the slider in my basket on the website, will place the order in the next day or day two, just checking if I might need some more parts.

We can start of with the exhaust cam cap as well. Do you perhaps have a spare one?

Don't know what these okes thought

Guess one one is the new chain? I'll give you a hint.  It's not the left one. 

ooooooooo noooooooo what happend my bike did that but i got the drain fixed and always use the stock filter fidget with the oil galleys a bit

dude you always gotta run clean oil in these bikes i change mine every 300 miles or 600 if shes gettin good in

10w40 luchas pro motocross oil and im thinkin about gettin a oil cooler idk if they even work tho i am going to exaust wrap the header

i run 103 octane in mine and never has any engine problems and that timing chain has to be tight and the cam caps torqe them to 7.5 ft lbs 

lash should run .35 at .000 mine starts first tap of the starter and idles perfect needs a new throttle cable its done wore out and i will have recent great ideas for this bike soon

i have a great look for this bike and a motocross setup where the seat is up to my abs and it has weight reduction need to get rid of that pipe lol have ideas of putting a shorty baffle on it

i have straight piped my bike and im building a custom muffler for it

i will have updates within 5 days it looks sick ive found a great lowered hard tail desighn for this bike

i painted the frame flat black it has the shocks flouresent yellow im going to paint the hubs and rims flat black and spokes that yellow it looks sick

still blue plastics and the lowered shock and hardtail looks insane still utilizing all mounts and quick easy ilistration  were talking lower than a harley

and its great for the street side and the extreme dropped shock will be great for raid and street low tuck low profile street moster and ready to dive off the road now i have it lifted so much 

the sag i set at  '1  ''  1/2 its as high as a 450

and the suspension is highly tuned all  stock too this is the best stock suspension ever hydraulic sucks id way rather have air

  I wont stop posting, but is is ridiculous how I need to wait for simple stuff. Only Received Steering Bearings today, So i can start fitting the tripple clamps back on. 

Wont be able to fit the shocks back on yet, as i need to WAIT for Shock Protector Boots, MIGHT get that later this afternoon.

This is simple stuff that is supposed to be off the shelf at any respectable bike shop.  but its not! Everything i have needed for my bike thus far needs to be ordered, Its like the Bike shops are relying on customers to carry thier business, and they dont want to carry stock. Stock is money laying around.... 

But nevertheless, I`m still in high spirit!  Bike will be Completed

 

 

looks spectacular man i think these bikes are the best they look good nomatter
what you do to them does that wite look good and im thinkin about painting my
plastics orange blue and yellow or all black and blue with dabs of that flourecent
yellow on the front forks look good asfffff paint the rims and frame u will be in love
with the way she looks the flourecent is something to look at and a sparkly base coat
with tons of layers of clear mannnnnn wow i love the ttr

a 12 point will work the best or use a 8 point if u use a 6 u risk not being able to get it off ever and never use a oem ****ty bolt on these bikes always use genuine stock parts and then u can modify them if you need and still have the old one

So I bought the Raid. Running condition. I'm happy, it stil rides nice and solid. I'm quite surprised the about the difference between the OE and the raid.  The raid is much lower. 

Thanks buddy, I'm stoked. Actually bought the bike for my brother. We are planning a weekend trip thru the Baviaans mountain range here in SA during September. You should Google it, it's a awesome stretch of dirt road.  from there he wil take the bike back up to Cape Town  to his house. Drove the raid for about 50km tonight and it never skipped a beat, so I'll take that as good news for now. First need to sort out the OE before I'm lifting a spanner to work on the raid. 

Hey Bud, i have been living on Gumtree the last couple of weeks, and for some or other reason I did not see this one advertised! , I would have bought it! 

The Raid I bought was advertised for 19K, i managed to bring it down to 14K after highlighting some issues, owner believed the Raid was a 2011 model.  One thing that I have noticed is that both the OE and Raid does not VIN plates on the frame, is there a reason for this? Or is it just on a hidden spot? 

Yes, we are stoked to do the trip. Will be going thru "Die Hell" as well.  We are in a huge drought, so  the road should be open by now. Our planned trip is only later this year.  I wil also be leaving my bike it Cape town then for a later trip back down to PE. 

When im done with my bike, i will clean up the Rais as well, the previous owner spray painted the nice purple rims black.....and its peeling off badly, so ill just get that off. Should be easy. 

Better Pic of the Raid in my Garage, Please excuse the condition of the floor, need to sort that out, but that is a project on its own...  

 

 

 

That road looks lekker!

 

I was contemplating on posting the below, Felt like a dumb ass when it happened. I saw all the warnings associated with the removal, but I was a bit impatient when removing my clutch basket, and ended up breaking one of my pins off. 

Luckilly, a good mate of mine has a engineering shop, and we managed to sort it out within about 30min! 

Turned a new pin, threaded it, Machined the mating surface, and tig welded the back.  I believe it is even stronger than before.  

 

Before - Im such a dumbass.

 

Fixed - Hell yeah! 

Hi guys.starting with the head assembly. Seated the valves, and got a nice seal when checked with some fuel. 

Wil be fitting new valve stem seals as well. 

No im a bit confused looking at my parts that I layed out. The washer third from top, I'm sure this ain't part of the valve assembly, but for some reason I placed it in the same holder as my other parts from the head. If this doesn't go on the valve, what is it for? I've got the exploded diagram, and it's not shown on there. 

Hi 

yip, as i went along to fit everything, it became clear it was the head bolt washers. 

Got everything assembled except the clutch.  going to make a clutch tool today, as i dont want the pins breaking of again. 

So far everything went together nicely. Just one valve cap was a bit tight, had to polish the cap a bit to get it to move easily 

 

Easy to lose the ball bearing when stripping an engine as you tend to forget its in there and it rolls out at some point and gets lost on the garage floor 

Best put one in when you rebuild the clutch or it might not work properly plus you might cause some damage without the roller action of the ball bearing between the two rods.

8.7mm in diameter - you might be able to match it.

Hello Everyone

So this weekend I managed to get some headway with the OE.  Managed to get a 8.5mm ball steel ball from a Autospares shop about 50km away from my home. I was in the area and took a change.  Fitted the 8.5mm ball and looks like it wil work. 

Found a slightly different way of fastening my clucth basket, with the help of a friend and 2.5m of towing strap we managed to achieve a torque of 75nm. Stil a risky move, but it worked!

 Motor was fitted to Bike, clutch adjusted to mark on casing. and carburetor cleaned up. despite it lookign very dirty on the outside, it was in great nick on the inside. So nothing to worry about there.
