I ordered some new intake valves off eBay, but the wrong ones were shipped, so I still have a while to wait to get the correct ones. :angry:

I'm still deciding if I want to go a size or two over on the pistons to freshen it up there as well. I'll need to measure the stock Z1 head gasket I have to check to see if that will work.

While waiting (again) for the valves, I got the new spitfire mounted on a stock rear wheel from a '75. I have a new found anger for rim locks! :angry:

Found a pretty good combo to polish the hubs with - Buff Magic polish on a wheel, followed up with Mother's billet by hand. Turned out pretty well! Even better in person

I was about to mount up the new rear wheel last night, but found the mag that was on the back had a smaller rear axle. Once again back to eBay to get a Z1 axle...

Note my advanced redneck motorcycle stand, consisting of 3 jack stands :silly:

Finally starting to look like a bike again! Spent several hours cleaning & polishing the rear wheel, have that mounted up.

Also found a nice Craftsman motorcycle jack for $25 at a garage sale, so my redneck setup is no more. Love this time of year!

Does anyone have a recommendation on someone to bore the block near the Detroit area? Willing to drive a reasonable distance. Also travel to I also travel to Grand Rapids & Toledo often.

I put a telescoping T-style bore gauge down and did my best to get a decent measurement, and cylinder #2 was consistently showing a measurement of 66.47-66.49mm, which would put it way outside the spec limit. I'm looking to order a .5mm oversize set from Z1E to keep it stock.

Bike is coming along great!
I'd let the engine builder order the parts.

This may be a non-starter, but there was a machine shop in Taylor, Mi that had a good reputation. Haven't lived in the area for a long time though. But may be worth sending out some feelers about them. They do high performance work. Dave (StreetfighterLTD) would probably have a more qualified recommendation for the Detroit area. Or you can inquire with Les Holt, one of our vendors here who is the owner of PDM Fabrication / Machine. Look in the vendors section, he mentions that he is willing to help take on some engine work. You can also reference his ad at the bottom of this page for contact information. Good luck.
