tracked down a period rack for this thing, it actually crosses over to a 'yj2 campus 60' as well, so i looked on ebay and ONE came up . chrome was garbage but, i bought it any way.

going to get it powder coated over the winter i think, and i had to relocate the turn signals (this is actually where i have seen a few factory signals mounted).









donut hauling: enabled.  :whoop:

spare set of cyls back from the shop being bored to freshen up the top end .. one on it has a slight tick that might be? piston slap. 38.5mm bore of fury.

I had a hell of a time finding a shop that could go under 40mm.

Back when I worked at a machine shop in the 70's we did those tiny ones on the Sunnen power hone. It could do .010" no problem petty quickly.

yeah, its hard to find around here now, anyone that can do it that small. The local shop that does automotive was going to do it with  connecting rod hone machine they have, but got backed up and it sat there for 6 mos, which, i get. so i sent it elsewhere. 

The shop that did do it was way the fuck out of line price wise though, I sent it thru my local guy, and it was so high he refused to charge me any markup. to the point, he also wont use them anymore (as he also was rebuilding heads for him as well). he got invoiced $300 to bore those. thats insane. I would have been 'ok' w 100 a hole my cost, due to adding a middle man, but ffs.

Cool ride! 😎 My DT100 cylinder sat at the local machine shop for like 4 months before I  got a call back. I had sort of given up hope lol. $300 is crazy just for the bore job?!
