    Does anyone have any idea why my bike is harder to start when cold? I think it could be rings/piston. My technique is usually kick it full choke until it sputters, then mid choke it will usually start but die first time, then mid choke again, get on throttle to keep running. Maybe I just need to turn up idle more?

    Check your valve adjustments. And the pigs don’t like any throttle till the motor warms up. So yes turn up the idle a turn and reduce it back as the motor warms and the revs pick up.

    The valves are fine, I just checked them. I'll give increasing idle a go, thanks.

    It needed some small pilots drilled and then tapped. Easiest thing ever. The hardest part of the job was realising I should have done it years ago....

    Strip bike and test fit - see the little sharpie marks where screws will go. Remember to use some cardboard between fan and radiator to space it out a little..

    Drill wee holes (don't go too deep) and tap. You can see the cardboard spacer.

    You have to grind down the width of the temp probe a little to fit, then zip tie the excess cable out of the way.

    Done. There is about a 1-2mm clear gap even though it looks close to the fins. For power I just took off the green and black out of the RR in the headlight cowl. It works incredibly well. Even on a hot day I can leave the bike idling. It'll hit max of 105 degrees C but stay there under control. When riding the bike now tends to always stay below 95. I could likely bring this down a bit having it come on sooner, but my bike seems to be happiest when pretty hot.

    The YouTube guy jakegardensnake did a video on fitting the trailtech fan. It's very useful and removes the need to think to much about the job.

    Are parts still readily available for these bikes? I was playing with the idea of getting a BRP but not if parts are becoming obsolete.

    ^^ Depends on the part.
    Plastics readily available. No prob when I needed a water pump. Good luck finding a spark arrestor, though....
    Good aftermarket support for upgrades & interchangeables -- sprockets, filters, bars, stators, lighting, carbs, suspension, etc.

    BRP still has a following.

    Those are aftermarket radiators right?
    I bought a 4” spal fan and my radiators already had some sort of bracket(I’m just guessing it’s the original radiator ;) )

    @theailer did the fan bolt straight on to those radiator tabs? I thought you'd still have to make up some sort of bracket?

    Yeah I had to fabricate a bracket, but that was easy. Just a sheet of steel and made a hole for the fan and fasteners in the sheet.

    To bad the 600 didn’t come with a auto kickback device like the 650R. Hard on the leg and the kick starter components. Notice how hard the lever slams the end of its travel. Enough energy there to wreck or trash the engagement pieces. My bike did this once with the stage 1 cam that doesn’t use the kickback device. All that inertia stops on a dime when the kickstarter returns back to rest. Like a sledgehammer on starter gear.

    Ouch! My XR600R booted me back a couple of times, but nothing like that guy....

    When mine did it my knee smashed into my chin and nose like the guy in the vid. Not good. The power of a good backfire is unstoppable

    I have a question for the masses here that I’ve been pondering for a few years. Has anyone really launched their pig big time. Or tried to scrub or tail whip it. I don’t know if it’s possible or not, but I’m hesitant to try seeing the bike is over twice my weight. I’ve broken too many bones in life and I’m a bit to old to break more if it’s impossible to do.
