Did you manage to snaffle those nice red panels off Ebay Karny?

mr karnage · Guru

mr karnage · Guru

the only way is YAMAHA DTR · Guru

hi mate, i used turtle wax blue recolour to get my rad scoops nice again,

think its brilliant stuff you should try red smile

also what fender are you putting on the front

mr karnage · Guru

its come out nice after a clean and some autoglyn super resin polish but you can still tell where stickers have been

its got one that came with bike but going sm so gonna change it

might go with a white one and then put a hpires on back

on the barrel i started doin i jus reshaped the leg things to guid the FnA round smoother (in theory anyway lol) but i think increasing crank case volume is a bad thing so not sure if you should m8?

mr karnage · Guru

ive still gotta do the cases

i dont know whether to cut the two little legs on the bottom skirt off

every ported dt barrel ive seen has had it done but dont know if i should?

mr karnage · Guru

ive done exactly that

now its more or less parralel with the cases

mr karnage · Guru

Hp rear and no grab rail and it will be a one off not seen before. They don't even have red ones in this condition in Portugal

mr karnage · Guru

my dtr so far
managed to get jumped and loose my phone so ive only got pics of what its like now and my account only just got approved lol

heres how i bought, it was in a bit of a state but it had a ypvs and it was red so i had to have it, set me back 570
just noticed it looks alot better in the pics than it did in flesh and someone had took a paint brush and painted the frame and swingarm
heres how it sits now
stripped it down to bare frame and had it powdercoated then rebuilt it, replacing everything that was siezed or ****ed and cleaned all the rest up. replaced eveything rusty on the bike and new bolts all round.
just waiting on a wheel spindle no then i can get the back wheel as someones put a spindle too short so it doesnt fit unless the chain adjusters are removed

another thing iv noticed aswell about the barrel skirts on tuned barrels same as u say about theshorter reshaped skirts i found this pic

mr karnage · Guru

ive been looking at that pic aswell

mick abbey init, the discription says its tuned for a nice power throughout the range

and that gear levers a rfx one for a yz 125

NORFE · DTR Trusted Engine Builder

yes mate ma tuning

emailed him and asked him for prices & its 160 squid for that barrel & hed work to match

im working on a barrel now doing the same as the picture and get the ports cleaned up and mre angled

then when my top end is worn out im gonna fit that one then see what that feels like smile

mr karnage · Guru

sounds like a plan

im going to to a proper job and sort the windows and clean up the rough bits where the sleeve meets the cylinder

mr karnage · Guru

bought this crankcase with a missing stud and the thread had been double threaded and without realising i went to put in a new stud and it went in at an angle. had to get it welded and this is how it came back

scaled.php?server=856&filename=dsc0030lp.jpg&res=landing

then i started grinding it down with a dremel and this is how it ended up, the bubbles are from the welding. he did say the stuff he used was a bit **** to work with but wasnt expecting bubbles

looking smart mate keep up the graft!

CarlosRexx · Guru

Not a bad colour tbh :D

benjarminx · DTR Respected Member

saw you on a 4chan great bike mate

mr karnage · Guru

After putting the bike in storage for a year it's been taken out and work will resume

It's all just how I left it except a bit of dirt, mould and tiny bits of rust on the dep

Haven't checked the piston yet but it's not seized

mr karnage · Guru

Oh yeah and that weld on the case didn't last, second time I tightened it the thread went so replacement case it is.

Calum122 · Guru

I've reread this thread

Did you say that's an SP barrel! The porting is HUGE!

Where'd you get that from? Incredible.

Love this thread. Awesome work gone into it.

mr karnage · Guru

Oh no that was just comparison, I don't own one. Wish I did haha.

I scoured the Internet for pics of the porting as I was going to port my own barrel to similar specs. I did actually learn quite allot. I've still got port maps and port window specs but the bike had to get put in storage for a while and I've only just started working on it again but decided I'm just going to give my spare barrel to mick abbey. That's why I mentioned in the other thread I wanted to have the head machined to take o rings.
