Hello Vital,

I have been reeding and enjoying all those bike builds for the better part of 20 years, jet never signed up to post.

I have build and restored a hand full of bikes over the years and most of them were Honda’s The xr600 to me always had such a thick cool looking engine. But I had never owned one or even riden one, untill now.

These are becoming scarse here in Holland, so the first one I found on marketplace was mine.

It is very hard to start, but I figured some practice would get that sorted

So after changing the plug, measuring the coil resistance and watching videos on the starting procedure it still is hard to start.

Then a PD04 electric start engine poped up online

It had a cracked cylinder head so i swaped the original head onto the E-start cases. It still has a kickstarter too. Fired first kick.

The XR engine looks cool to me but the flimsy suspention does not match.

I had a crf fork laying in the garage so I made that fit

So with the new fork, the rear swingarm could use some beefingup

I got a 2016 crf shock and swingarm and brakes

Had to modify the frame at the top shock mount and at the lower linkage side. Then put my crf wheels in to testfit

Also the kickstand spring pin on the frame was worn, so I made a new one

Next thing I found is a set of crf wheels, excel rims and Talon hubs with a crush drive/ damper on the sprocket.

For the rally tower I drew up some plates and tried some things with plywood.

When I was happy I 3D printen the plates to testfit

So after mocking up it is time for paint powdercoat and chrome.

Took the engine apart and pulled all the bearings

The cases will get cerakoted:

Swingarm and rims get wetblasted

Also a new Cam and camfollowers.

This is becomming a moneypit, but no way back now.

XR600s are awesome on dirt roads 3rd, 4th, 5th gear! 

And this year is one of my favorite years. Absolutely love the bronze lower engine cases against the red tank and blue seat.

The interesting bit for me is to see if the central cam bearing can be fixed. It was worn like most. Cut the existing bearing to a langer diameter and put a custom brass bearing
