I was thinking if you slapped in the other crank to see if it changes.

What I was thinking is getting a 78mm crank off ThumperRacing. It would then complete a 660 with all the parts I have, oh I’d need another piston kit as those cranks run a 19mm pin from memory. My 610 kits I have here are 20mm pins. I have a 570 motor here with a blown crank. I could do the 660conversion to it. Also I bought a KTM conrod repair kit for this blown crank. It would give me two 610’s and a 660.

I found the vibration. Itís the handlebars. When you place a finger on the triples, virtually no vibration. Same anywhere over the bike.

Out for the run in today. Well that lasted all for 1/2 an hour, then into it. Beaut day for it. Getting a sniff of Spring. The 610 with the current mods is one nice motor. My problem has always been ĎI want moreí. Today proved that the 610 can be too much. Not that Iím having troubles handling it. I would like more. Just that there isnít a lot of traction the bigger you go. Iíve never been about going fast, even though I donít have troubles doing so, just that Iím all about having fun. This is where this bike excels. This bike will lift like no other. Awesome fun.

They seem very nice. No vagueness. Haven’t tried without.

Sorry mate, it still vibrates way too much. The ride today confirmed it. Itís going to have to stay like this for quite some time. Got other projects to do.

Be buggered if I know what could be causing it though.

I read the 390 crank is heavier, maybe that can help to stop the vibes???

Hi Wawaron,

The 390 has a shorter stroke.

The 390 has a lighter crank assy compared to 570. The difference is the longer crankshaft.

I have some Xtrig mounts similar but they wonít fit the KTM triples.

I placed under and above the handlebars and under the mounts some reinforced rubber. Worked real well.
