Just ride the living c×=/ out of it, if it holds together it's a good one.
Nah. Much like the others said.
I would also add, try not to hold constant revs. Don't be scared to give it bit of a hard time, just don't let it rev it's ring off.
Although this was for cars. A mate of mine who is a long time Toyota mechanic, trainer and one of their tech gurus, advised me to hop in my new diesels and drive them like they were stolen. Best thing for them is his advice.
Ya cheap bastard
I’ve only ever had two new bikes - TR650 and the 701. Both bikes I followed the book for the break in and both bikes acquired a serious oil guzzling habit!
With the TR I had the rings replaced at around 28k and it did not improve so maybe the problem lay elsewhere.
The 701 blew the big end at around 14k while being flogged in Tasmania. When the Husky dealership put it back together I decided to try a different method and rode it hard from the front door of the dealership and for the next few days in Tassie. Now it doesn’t burn oil.
I may have just been unlucky but I think that I was just too gentle the first two times. And when I say I rode it hard that is by my standard - not bumping off the rev limiter - just hard acceleration, some sustained high revs,
but mostly varied.
I brought a brand new '94 KTM620 EXC, which was the first new bike Id ever brought & being as excited as fuck and a bit nervous as well, so I asked the mechanic at the dealership who I knew well enough, how I should run it in ?
He had bit of a chuckle & told me he'd just come back from a factory tour in Austria & watched em been put together & he said just before the engines go into frames, they go on a dyno, stone cold off the production line, hooked up and maxed out to see if they come up to spec, so he said dont feel as tho you have to baby them, just ride em like normal from day one & you wont have any dramas. I did as he said & that thing never used a drop of oil & went like a bullet.
Ive always remember what he said & have had lots of new bikes since then & theyve all been broken in the same way & never had a drama.
Pretty much my thoughts Fabnut... don't baby it, put it under load as per normal riding, a few heat cycles. If it doesn't shit itself in first 5 mins, it won't.
Well... enthusiasm abounds this evening. Lots of fiddly bits, sprocket guard on, fitted heat shields to fat pipe with a fair bit of modifying of mounts and bending of shields. Fixed and re routed wiring, fixed a seized airbox rubber mount, etc
Start it tomorrow. :)
Yep. If you ignore the bulge in the pipe, looks just like a stocker, huh.
Boom...... I got busy.
Starts, runs, sounds fat. Like a rally bike engine.
Can we listen... pleeeeeeease...?!
Check your fb troy. Sounds average on my phone, much better in reality
Even on the phone it sounded pretty grouse... but naaah... you don't get the full "thump thump thump" percussion experience over the internet.
So. Well. Interesting.
Went for a few laps of the block terrorising small dogs and children.
I'm grinning like a fool, more than usual.
It hauls. In 3rd and 4th , open the throttle, instant increase in revs. It doesn't build, it just goes from 4000 to 6000 in an instant, with a corresponding speed increase. I initially thought the clutch was slipping it revs up that quick. Mono, can do. Wow. Never ridden anything like it really.
Given an increase of near 80cc, and a cam , I'm worried about fuel delivery and timing.
A call to Vortex hq and then PTR and they both say it isn't as simple as winding up the fuel by 10%, which I knew would be the case.
It needs to be remapped to ensure proper AFR's and ignition timing .
Seeing as I don't want to hurt it, it will be dropped to Taintons in a week or two for tuning, to get the best from it and make sure it keeps on running .
But hot damn, I'm impressed.
Watching this closely Richo.
Interested in rwhp dyno figures.
The 654 survived Hidden Valley and has to go to PI in a couple of weeks where I will be seriously out-horsepowered and 20+ kph slower down the straight in my class.
Gunna need a few more ponies for next year if I run in the F5 again.
Do you have a vortex already Jak?
Yep, and Akra underbelly pipe now - removed the one-off Staintune as I would have got pinged for excessive noise at Hidden Valley.
Vortex was trimmed originally for the Staintune, slightly opened-up airbox and foam filter(for original 654engine)
Prolly should check AFRs now I’ve changed pipe and running paper filter.
My old (47000 km) engine breaths pretty heavy now and noticeably down on power.
Original motor when new according to PO was 60rwhp.
Still original rockers
The ‘project’ 690 is a 13 Duke (twin spark), might have to find some enthusiasm and finish it
Maybe 732 this bastard if yours is a winner
PTR have to get the base map for the vortex , then start to map it from there to optimise Air fuel ratios across the rev range. And modify ignition curve to suit cam.
A few hours on the dyno.
Interesting graphics for a 690, I reckon it works well, matches the 450.

You gonna' go that colour scheme on your monster Richo' ?
