running hot

[actionjack]

Yamaha usually runs a straight blend of antifreeze ,I would try to drain some of the fluid,add some purified water ,usually 75% AF,25 % water mix.Straight antifreeze retains the heat longer,the water mix will disperse the heat and allow better flow rate,also remember to let system purge and refill if needed.My new Apex and a few other new sleds I had had same symptom until I did the service and never had any issue ever after that,even in low snow conditions.Give it a shot,it worked for me.

This was definitely true with my Apexes. I can't believe they still do this. Change to 50/50 and no need for rear exchanger in my Attak. Guess I'm doing this with my Winder too.

Good luck with cable scratchers I got went through 3 sets of duraflex on my nytro in 2000miles they kept pulling the hooks off and this year just got a set of straight line performance for my BTX LE and guess what they look nice but the end ripped off with 300miles down on the trail and now I got new slides at 500miles cuz the one is shot! Back to normal scratchers just think when you back up.

Had a mach z foul plugs once so used the headlight from my idling apex and after a while, it shut off by itself. Restarted with temp light on but it went off after some snow on the running board exchangers.
Heated up once last year with thin snow on a road for miles, so picked up the pace and the air from the track fanning the tunnel exchanger put the light out with no real snow....a friend got scared so I said go faster and his light went out too...on a vector. Dont like doing that, but they really weren't that hot.

Thanks Drant. I may try those. The flexible ones would hit my track & take some rubber off. I guess i should just slow down when scratchers are on, but then again maybe i should just slow down period. I plan on changing coolant after break-in & adding scratchers so just looking for all my options...

What about running scratchers inside the ski? Anybody have good results doing this?
