    Ten months ago I started restoring this classic beauty and I'm getting close to finishing it so I thought I'd post some pictures. Heres what I had to start with more or less.

    Everything was in good condition considering some of the thrashed race bikes I've seen. The frame or pipe didn't required any welding repairs, just disassembly and paint.

    Looking at the empty cases pictured on the work beanch you can see why these motors were referred to as the pumpkin motor.

    Heres the motor in progress. Cases barrel and head were bead blasted and blown off with compressed air, all threaded holes were cleaned out with a tap (I love assembling an engine I can screw bolts in without binding) then washed in alumi-prep and rinsed blown off again and dried before painting. I used VHT black semi gloss cured on the BBQ.

    Kick starter foot-lever was zinc plated. Carb was disassembled and dipped in carb cleaner over night then rinsed and blown out with compressed air then the main body, cap, and bowl were bead blasted.

    New gaskets, seals, piston, bearings, clutch plates, etc. Leak down test was also performed and the timing was set to factory specs with a dial indicator.

    Frame paint is a custom urethane created by hand from an NOS swingarm. It may appear more gray than most which tend to lean towards silver.

    Handlebar clamps were bead blasted and the black m6 allen screws are coated so they don't rust. In the past I've found that plain black oxide screws rust over time just sitting in the garage.

    Steering head bearing races are zinc plated as are all the Bufo bolts. The secondary coil was bead blasted and sprayed with a clear coat, mounting tab was masked off for a good ground.

    The silencer wasn't a stock option on this bike but it was a Husky option that could be purchased separately. I felt fortunate to have an exhaust in such good condition.

    Girling are the correct length, bushings are excellent. Springs are the correct 75lb rate.

    New nipples and stainless spokes. I tried to have the original spokes and nipples zinc plated by two different plating outfits and both times they looked like crap so I went with the aftermarket stuff.

    Tank was done by Vintage Husky, chrome, paint and decals cost $800 with including shipping :eek:. Looks nice though. The color in the photo is a little more orange than in person, which is red.

    And then I #&$! it up!

    I had the tank resting upside down on top of a bucket, with a towel as a cushion no less, and the top of the bucket caused the paint to move. I was de-rusting the inside and had to turn the tank upside down because I didn't have enough de-ruster to reach the top. I sent it back to LeFevre and should have it back this next week. For those of you who aren't familiar with tank a resto, the chroming process causes rusting inside the tank so the best time to clean it out is after re-chroming and before painting. The tank sat for an entire month after I got it back the first time so I thought it was cured, after all it was 95+ degrees and 9% humidity the entire time.

    The forks were washed, bead blasted, painted, new slider seals, and copper washers on the m7 allen screws that fasten the spindles and new copper washers on the oil filler screws on top. Caps and washers were zinc plated. Notice how nice the bottom of the forks are. Theres no battle scars from rocks. I didn't re-chrome or replace the stanchions because they are in good condition and its a big expense.

    Bars are the early narrow style that were mainly pre-71 but the guy who I'm doing this build for liked them more than the later wide style. I didn't polish the lever clamps because my experience is they just oxidize in a of couple years. New Magura grips. Refurbished original Magura throttle.

    That is very nice. The tank faux pas is familiar. I put a freshly painted zrx tank on a bucket (only for a second), .5 seconds later It rolled across the shop floor... i said to myself...self that's gonna cost ya. It did.
