It's not leaking anymore. I was in doubt about the way it should go in, with the metal side out there's also a bigger chamfer, and indeed, the spring is usually on the oil side..

I did wonder if this is the right way.. It always has been in like this..

Might have solved the problem. Haven't taken it for a ride yet, but so far it looks good. Made a tool so I can "press" it by using the crankshaft. Lot of grease around the seal. Still looks like the rubber is stripped off of the seal, but a lot less.

Looked up the partnumbers, GS1000 and GSX1100 have the same oil seal. How did you tap it in? https://www.cmsnl.com/suzuki-gsx1100-1983-d-general-export-united-kingdom-e01-e02_model13730/partslist/FIG-10.html https://www.cmsnl.com/suzuki-gs1000-1979-n-general-export-e01_model13512/partslist/FIG-08.html

Getting it out is not too hard, but when tapping the new seal in the coating of the seal comes of real easy... Like these seals are more tight then other seals..

Is there a trick / way to replace the crankshaft seal without unbolting the crankcases? And without damaging the seal? Thanks

It looks nice, but I don't think it's going to work. Rear wheel seems to be too wide, sprocket has to go that far out that the chain wil run against the frame. Rear end is raised to much, so the chain will run over the swingarm.

I made the clutch of my GS1000 hydraulic. Got myself a clutch slave from a Bandit for the measurements, you need at least a lathe, and a preferably a mill, and some imagination. But it's not too hard to do. See if I can find some photo's

I finally found an affordable TD04 turbo, good condition for $150, 25km from where I live. I started the modifications already. The TD04 is quite a bit bigger then the VF20

Finding the right headlight is a challenge indeed.. I've got this, the left shell, but about half of what I paid for it.. https://awmotorcycleparts.co.uk/search?q=310221

Daihatsu Charade GTTI intercoolers aren't very big

Electronic ignition from an GS850

Lean? I thought too rich... But I need to ride behind it to have a proper look. I have to ask my mate to go for a ride.. I don't like smoke either, no matter what color

Couple of months later... Bike is going again, had to get the pistons machines so it would take the piston rings (I'm so not impressed with JE), had to wait for parts (gaskets) Can't get some gaskets anymore through Suzuki... Installed the gas flowed head, I must say, it does make a difference!! It's more aggressive, better throttle response. It did lift it frontwheel in 3rd gear on occaision, but now it does it a lot easier, it even lifts it in 4th. The balancing did made a difference!! But not as much as I hoped for, but maybe it's something else what's causing vibrations, my mate says that 4 il engines always have some vibrations. It's at an acceptable level. The less vibrations and the head gives it a bit different characteristics, revving it up goes easier, but now I start to notice that the turbo is too small. But it has an incredible strong mid range. Haven't taken it for a longer trip yet. Smokes a bit when decellerating, grey-ish smoke, have to fix that. Put new valve seals (OEM) and new piston rings on it.. Not happy with this First ride on it, it didn't feel right, like it was lazy, bad response on the throttle... Turned out the grips were loose

I've got it like this. Made up a spacer for the rear axle, got some 5 or 6 mm plate, and made the calliper on that, and welded that plate to the spacer of the rear axle

Got my bike going again, put the gasflowed head on it. It defenitly makes a difference!! It's more aggressive, lifted the front wheel in 4th gear, and still it's not real fast Haven't riden it much yet, it smokes like hell, have to fix that first.

No experience with EFI, but I noticed something. You say it injects every second turn of the crank. Would it run better if it injects every turn of the crank?

Going to get expensive?

Probably on the newer cars then..

I better start making a 3" exhaust then..

I doubt if it makes any difference, where I usually see where the frames are "reinforced" are mostly done on sections where it doesn't do much/anything. And where it could make a difference nothing is done. The engine gives the frame quite a bit of stifness too.

I bought a 1238cc big bore, new JE pistons, new sleeves, never used. Con rod snapped, wrecked 1 piston.. and more.. JE has a service that they can make a copy of a piston. But the minimum is 2 pistons. The piston I send was a JE piston, but for some reason it didn't have a serial number in them. The "exact" copies I got were 10 grams lighter and 0.05mm bigger and the oil ring groove was overlapping the hole for the wrist pin. So no full support of oil ring I complained about this and they send me 2 other pistons. Never tried the rings on the pistons because of this. I used the old piston rings because they had only done 3000km, cilinders bored up and honed, ring gap a bit was bigger, but took the risk. Old piston rings fitted just in the grooves, they were a bit tight. Took engine apart to balance the crank, had marks in cylinders, had them honed, and the rings were a bit tighter in the grooves. Deceided to get new rings hoping they fit better in the grooves and getting a proper ring gap again. New rings won't fit in the grooves, rings do fit in the grooves of the old pistons. JE doesn't make rings, they get them from Total Seal, these rings come from Total Seal. There aren't variations in 1.2mm and 1.5mm thicknesses, it's just that or a complete different size. JE fucked up twice.

Oh no, they fucked up!! The rings fit in the old pistons.. 1.2 - 1.5 - 2.8 They just don't fit..

The rings came in today. The instructions give the same numbers as Wombats list. I need a gap of 0.4mm and 0.43mm. The gap was about 0.7mm. But the rings don't fit in the grooves.. JE uses Total seal piston rings, but JE doesn't made my pistons so the they can take the rings.. So not impressed by JE..

You also can have a restrictor what doesn't restrict enough.. I also had a leak from somewhere I couldn't find. Turned to come from the up pipe, smaller hole in the restrictor solved the problem, and the oil pressure stabilzed a bit.
