Front fork rebound adding helps a lot, if still shaky use a PC linkage on the rear and get your sags/ springrate correct.

Added reply in a thread Very difficult question about water pump 2/4/2019 5:21 AM

Why should it be good to delete the ATAC system? It makes the engine more userfriendly, should give more torque down low without costing any power in the upper revs. The governor "steers" the ATAC system. By chosing different springs and/or balls you ... more »

Its induction heating here and it heats the hole to insert the bigend pin with less force and more accuracy. Nothing gets hardened here. To save a couple cents on each crank at least Kawasaki has stopped to preheat the crank halves - the result is that ... more »

Thanks for the link - now I wonder if the results are the same at our revs and combustion pressures - I´m not sure as my engines have the gaps more or less where I placed them when tearing into them again.

I am interested what makes them rotate?

Added reply in a thread Purpose/Importance of 4t Piston’s oil ring gap orientation 1/26/2019 3:01 PM

Barnett,sorry for my bad explanation - will clarify herewith: think of the ring gap exposed by a piston off the cylinder wall or covered by a piston close to the cylinder wall. I think you will agree that a ring gap that is mostly covered by the piston ... more »

Added reply in a thread Purpose/Importance of 4t Piston’s oil ring gap orientation 1/26/2019 5:48 AM

The top ring should have its gap on the rear side of piston as when the engine turns forward, the rear side of piston gets pressure against the cylinderwall, thereby closing the gap further. Every other ring and spring expander ring should have the gap ... more »

Added reply in a thread Clutch problems Tm-racing 250 95' 1/21/2019 11:37 AM

Some pressure plates have teeth that need to engage with the inner clutch hub. So take off the pressure plate, measure the thickness of the friction and steel plates. Put the pressure plate onto the hub and check the space between the plate and the hub ... more »

the raised cylinder changes the timing of the transfer ports and exhaust a lot in the direction of higher revs with more power with a little powerloss at lower revs and gives a bit more time due to the lower compression before the engine will start detonating ... more »

Added reply in a thread Are KTMs super unreliable? 1/11/2019 12:31 AM

I have put over 160 hours on my SXF450/16. I never had a problem with the motor. By far the best brakes and clutch compared to other bikes so I bought a 17/450 and an 18/450 and a 19/450 - this time a HQV because the price was right. I tried all the ... more »

IF your throttle cables are adjusted correct, you can release the choke by turning the throttlegrip closed - this will release the choke knob and it springs back into the OFF position. If this doesn´t work, adjust the closing throttle cable.

Added reply in a thread 2016 KTM 350sxf Yellow/Red Knobs? 1/5/2019 3:46 PM

the yellow knob below the butterfly valve is your choke. Push it upwards and start the bike. If your throttle cables are adjusted properly, you can make the choke spring off by closing the throttle against its stop. The red knob is the adjuster for idle ... more »

Had a SXF 450/15 EU Version. Sold the bike when my 16/450 arrived but kept the CC forks as they were perfect. Had these forks in use on the 16, 17 and 18 SXF when I bought a CV fork. Still use that fork often. If you can get a 15/450 with the CC fork ... more »

Easy fix - machine it out to proper surface and roundness, press a sleeve into the warmed up head, machine the sleeve with internal dimensions suitable for the original cam follower and start all over again.

why use a hammer at all when a warmed up bearing will let the crank sink in under its own weight.
