Powder coat time!

Post by Skyguyz »

I had the powder coating done on all the bits that need it. Yes, paint is original but the powder coat will last longer. I am using all SGP (Suzuki Genuine Parts) from Paratzilla https://www.partzilla.com here in the states. It has a good supply of OEM / SGP and they keep arriving by the box full. The crank should be back any day now. The cylinders I opted to not have the off center bored ones repaired, (Too bad, they were vapor blasted and that reveled the off center bore.) I have procured a healthy set of cylinders , head and new pistons that were all machined by a vintage motorcycle shop here in the states. I will have them this week. Work progresses at a steady pace and the "Build" portion is underway. Slow and steady wins the race!

Nice looking powdercoat. Did they do clear over black to get that gloss level?

I doubt that the bores were machined off center by the latest machine shop - though that is possible. Suzuki bores were rarely spot on because the liners seemed to never end up in exactly the same place in the core box. The one thing to do is to check that the bore and head are concentric.

And use Cometic head gaskets for a decent seal. For the rest of the gaskets, Athena or CruizinImage are fine but don't use OEM or any other head gasket because the bores are too large and can lead to detonation

Update: New water pump in, crank in

Post by Skyguyz »

So, the cases have been gone over tip to tail with many blow jobs for FOD. They are clean, clean, clean. The new water pump went in and the locating screw is set. It just needed a slight tap with a deep socket to set it in place. New bearing and such, so fine. I was going to drill a hole in the shaft on the outside portion of the case if I needed to remove it without splitting the cases. But, I just couldn't do it to a brand new pump. It was oiled before it went in and the impeller vs case clearance checked before the waterproof sealant and gasket went on. I could have used the old bolts but the were in such bad shape I opted for new Allen bolts torqued to 9 LBS. The aluminum water case pump cover was cleaned inside and out and the old gasket gunk gone and a perfect dead flat surface for the install.


The crank went in with our a hitch. All the bearings set in the pins, the "C" locater in and all new seals aligned. Everything triple checked for proper install. The gear change and transmission are next. Stay tuned.

Tis a thing of beauty, it always seems a shame to bolt the top on so you can’t see the innards.
Glass crankcase anyone :lol:
