If I wake up in the morning and feel like superman I reach for the 500 but if I wake up feeling like Pee Wee Herman I usually ride the 450. I seem to have more Pee Wee Herman days. LOL

anyone have experience with oversized tank on the CR5? My compression release stuck in yesterday, the blow off hole melted a pin hole in the tank and dumped the gas. I can't believe I didn't go up in flames. Plugged it with a 10mm bolt and rode out... but need to replace the tank now. Just need to be sure the rubber boot for the head mount doesn't get wedged against it again when putting the tank on from jetting and plug checks in the future to avoid that crisis.

Clarke vs IMS 3.5 gallon? any votes on better fit? My decomp is rear facing and will clear any tank.

Anyone find the ski pressure on the older chassis is outrageous? I consider myself to be well versed in fork rake, track ski balance, TSS sag, fork height in clamps, spring preload, air pressure in fork legs and all the tricks...

But the 500 is laid back pretty far (30 degrees) and the ski pressure on the ARO ski is unbearable. My arms are getting worked keeping it on the trail.

I measured the rake on the 500 steel frame and its actually 32 degrees. KTM is 26.5 and Yamaha YZ is 26. The steel frame is a bear in tight places. I have a KTM 450 frame here waiting for a kit and the CR500 motor.

interesting, I shoot for 30 degrees on the the fork legs off a plum bob on the KTM and Yamahas (all my previous builds) So that makes sense that the frame rake isn't giving me the same feel on the CR seeing it's so much different in the chassis - that gives me a place to work from to get this ride closer to what I'm looking for. Thanks for the info M5. I might try steepening this up 6 degrees to see how it feels.

Don’t forget that trail makes a big difference too.

It baffles me why the kit builders don't make the ski trail adjustable. Just make the mount adjustable pretty simple stuff.

Snowtech does! It’s only two position though as far as I can tell. I initially thought it was micro adjustable.

once you get a 500 running right you might be looking for more ski pressure!https://www.youtube.com/watch?v=StHZXIumtjs

they are a beaut once they are sorted. i just have a little list i go through after every 2-3 rides and as long as you keep up on the little items they wont leave you stranded.

I run a steely frame with the big 4 gallon volcano tank, I love it. Yes it is more weight, yes the weight is up high where you don't really want it, but it is more fuel. Between that big tank and the 3.3 kicker that rides the tunnel, I have enough fuel to pretty much hang with anyone. I think we end up burning off the top half gallon on the trail getting to the good stuff anyway. I would not hesitate to run an oversized tank.
