ZG1000 in GPz900 clothing

[Chrome Megaphone]

I finally got my 1985 Concours/Ninja project running again after several setbacks which included a blown engine due to not replacing the rod bolts after a 2mm overbore with ZX11 pistons on 88-89 ZX10B rods and oil burning from wobbling valves elongating the seals because I couldn't resist tear dropping the guides during head porting. Lessons learned.

Anyhow, now with a re-ringed stock bore and eBay stock head wearing the GPz900 cams, carbs (Dynojet kit), and Vance & Hines advanced ignition timing plate she's not as spooky explosive as before but still fast enough and much more controllable. Yesterday after having it inspected I pulled out onto the four lane road with enough throttle to induce a power slide which was easily recovered from.

That's pretty slick. Take a lot to mount that bodywork?

It's a semi-bolt on affair that required some shade tree ingenuity to mount the ZG oil cooler, aftermarket GPz radiator, and securing the rear undertray.  Basically the oil cooler lines are a tad short so it goes behind the lower frame mount with longer bolts serving as studs.  AliExpress radiator needed two .5 inch rubber bushings, longer bolts & nuts, and a trick to get in there because the end tanks will interfere with the frame.  I couldn't find a GPz lower tray frame that goes under the engine so again thick bushings & longer bolts to the oil pan worked out.  The windscreen is an AliExpress part, it's a sport touring style slightly taller.

I didn't keep track of cost, you know how these things add up.  It probably would have been better to just buy a GPz900 but wrenching on bikes and cars are a hobby of mine.  Keeps me sane.

Here's my 1986 GL1200.

I consider motorcycle projects an investment in myself, the satisfaction of a job well done that bring many new things learned along the way.

Thanks all for the positive feedback 
I forgot to add a ZL900 Eliminator bevel gear was swapped in which really gets it off the line.

A few more pics.
Manual calls for dropping the engine for cylinder head r&r but I found zip tying the second row head bolts together with the bottoms flush with the mating surface allows getting it in and out.  These bolts are blocked from removing by the frame with the head in place. Huge time saver.

Front and rear rotors are AliExpress, so far no warping.  Wheels were cleaned then sprayed with 2K Clear Coat bodywork Rust-Oleum Industrial Black topped with 2K.

If I put on the ZRX1100 front end I have sitting in the garage the front forks, wheel and brakes will go on sale.

what is this screw ?

[Chrome Megaphone]

The petcock stopped feeding on me causing the engine to die on a two lane road in heavy morning traffic.  I coasted off into an uphill gravel driveway and dropped it, breaking the peg.  That's a temporary fix that's turned permanent because apparently the left peg breaks on every drop and they're near impossible to find.

Petcock has been rebuilt but I sure can use that peg if anyone has one.

Damn then, it welds well, I have already repaired 

Both parts were broken, as it was on the sidecar it is no longer foldable.

Nice work and far beyond my abilities.

Here's the overbored engine autopsy.  Two of the stretched rod bolt are on the case, they came apart like taffy.

Hello
Sacred damage, personally, I reuse the screws too and I never had this problem, I think rather that the condition of the bolts is not the cause, but the result, I will look more on a problem of lubrication.

The 3/4 connecting rod heads are lubricated by the small metal tubing and it causes problems.
