Yeah mate. I have all the numbers for the various cams here. I prob should elaborated on it meaning itís just an off the shelf cam. Going by his invoice it may suggest they had to buy a new core. Good second hand cores go for $50 but being a business I guess buying second hand isnít the go. Still, youíd think they would have given Jon the option.

Just me doing that assumption thing.
Thanks from TomTom

Yes I have a few assumptions here too so I'm waiting for answers.

Ok I got a reply from TR and yes they sent me the wrong cam by mistake. They will pay the shipping. So all good there.
I also had another question about the key hole timings on the crank. That turned out to be all my mistake! I saw a keyslot out of position and assumed something was wrong. So I didn't see the other two key slots! Who would have thought there was more than one?! This crank is for 500, 530 and 570, you just choose the correct key slots. Handy.

So now that is sorted I'm really glad! I didn't want to share this until I had the answer to avoid wrong assumptions and potentially unwarranted bad rep. One thing was all my mistake and the other was a mistake they will fix. Nothing to complain about.

So if anyone wish for any close up photos or details just ask.
Thanks from tourist and Alan

There are the two extra key slots! The two not to be used filled with jb weld.

I also got a DJH cam chain tensioner. Orange as the 610/660 cylinder is based on a KTM cylinder (seems to be more material on that?).

Good stuff.

Speaking to Travis re the 610 kit and cam, the cam used is of the later 10* shift in the decomp, so unless we have this cam to supply they use a new cam.

Iím considering the Thumperracing built cyl. It allows me to keep the original cyl plus theirs are more solid with larger water jackets. It saves me sending off a barrel etc.

Further to the specs, the lift is at the lobe. With a rocker ratio of 1.2 (?) this then equates to 10.5 mm.

Ok. Status. The cam is on the way now. Regarding the cylinder the ruined 570 cylinder I sent with the engine was swapped out to a better ktm (more material). I thought that I had to swap but that wasn't the case.. The price they offered for my cylinder was only 100$, understandable as they are doing this for profit, but that wasn't enough for me.

So... Why go full mental when you can go ape-shit crazy? Before they send back my 570 cylinder they will make it 590 The only way forward for that cylinder was bigger ID due to the damage, and as they already have it the only sensible thing was to let them fix it.
Thanks from TomTom, tourist and Alan

Ape-shit crazy? That’s the number my missus will do on me when she finds out about the 663cc of bent Berg motor coming out of Norway!
