    Dunno. Went with the Wossner because we wanted to get away from KTM's rings and the Wossner was great in that respect. Burned zero oil for 200hrs.

    My 41mm carbed 530 is blowing some blue smoke and burning oil so it's getting a Thumper Racing 570 kit and their reground cam, is there a link to a good set of step by step top end instructions?

    Thanks.

    Ned did one right here in this very thread. I printed it out and used it a couple of weekends ago to replace my head gasket. The only tip I would add is to mark the cam chain with a Sharpie on the link next to the TDC mark on the cam. :thumb

    Yep, I used Ned's procedure. Piece of cake, Nav. I can't imagine an overhead-cam engine being any easier to take apart.

    Go ahead and replace the valve stem seals while you're in there. They're not too spendy.

    Thanks guys, those pages will be very useful.

    I'd take that offer up on the 570 kit but I've already ordered thru Travis but thank you!

    The head is shipping out to DJH for a quick going over and a mod to the rocker shafts/seals/cleaning/inspection.

    Glad you caught it before any damage. I've got about 100 hours on a Wossner and had zero oil consumption as well. I've already got another piston and will change out this winter for good measure. Any wear on the pin?

    Just wanted to say thanks to Neduro and Hodakaguy for their awesome how-to's. Just finished up head rebuild, oil pump gear upgrade, skf fork seals and bushings. Just in time to take advantage of some nice weather here in ks. Thanks again guys

    Dunno. Was trying to get it put back together in time to take with me to King of the Motos, but that wasn't happening, so left it sitting. Just got back last night and am going to try to get this sorted out this week.

    Got my Highway Dirt Bikes fairing mounted today and had to go for a test spin despite the cold weather:

    [​IMG]


    The fairing works great. I installed mine in the lowest possible position since this is my trail bike. I'm 5'10" and at 80 mph the wind hits me in the goggles. It's a nice clean airflow with no buffeting. I like how it keeps the air pressure off the chest.




    I'm using a wide beam squadron as my low beam mounted in the upper position and pointed slightly down to illuminate the area in front of the bike. In the lower slot I have a spot squadron as a high beam pointed straight ahead. The low beam is run through an LED PWM dimmer with a high beam bypass all controlled from the handlebar Hi/lLo switch. This way on low beam only the top spot LED is on at 40% power and on high beam both LEDs are on at 100% power.

    Hope this is a fluke. I just installed a Wossner piston since I started burning oil w/ the OEM one.

    I've got 200 miles on it so far and all is well. Lets hope it stays that way.

    Send Wossner a picture and see what they have to say about it.

    Look sharp! :thumb

    From what I could see on the HDB website, the fairing and the bracket, etc. mount to the tripple clamps. Right? How does that feel off road? Does it make the steering heavier?

    I was wondering the same thing,Ive also forgotten what needed to be done to run an LED headlight,the stator gets something done to it I know. I try to keep stuff as minimal as possible on the front of the bike.
    Ive got a knack for breaking headlights and what ever else I put on there.

    The whole set up is very light so despite it being mounted to the triple it is barely noticeable.

    I dont know if the Thumper kit even used a Wossner piston.
    He called Thumper,they said.............bummer! Lotsa guys have run these 570 kits with no problems.

    Of course to add insult to injury he bought a complete 525 gauranteed engine from a "pro" builder.
    Special transmission gears where 3rd was almost the same as second.
    Then the sealed cam bearing blew to bits and sprinkled bearings through out the engine,broken gears,destroyed piston/bore,etc.

    Called the re-builder,he also said...bummer! And would do nothing. 4400.00 for nothing.

    That seems pretty good,Ive gotten used to ripping around with a compact chainsaw mounted on the ft end of my 200XCW,it weighs around 6+ lbs or so. Id like to have one of those quad lights on my 530.
