2007 apex at 22000km did the valves 2 exhaust were out of tolerance, and the rest were just in so did all valves except 2. Shims were about $10 got a great deal. Took about 3 hours. Shouldn’t have to do again. Apex like a diesel, cheap to run but high cost to maintain.

Going to start adding go fast parts to the 1200 and see how it ends up compared to the 2007 apex. 1200 120” skid, 1.25 ripsaw. Apex 121 1.25 ripsaw, 22/38 gearing and ulmer airbox mod. Both sled get same fuel economy currently. From 30 mph roll-on apex pulls away at a walking pace. This...

Trying to get a hold of them, no answer, are they still in business? Trying to get their clutch kit for 2007 apex. Bought 62 gram weights, orange Dalton primary 28kg/139 kgDalton 52r-46 helix, pink/white secondary spring. Have not installed secondary spring, using stock Yamaha pink. Tangs on...

Decided to keep apex vs buy new. Going to install rmotion with elka shocks. Want to increase seat height, need suggestions. Also run hauck exhaust with muffler, their quiet trail version. Would like to hear from those running this exhaust if they repacked muffler and if so what type of packing...

How do I do that? You think a sensor is reading coolant temp warmer than it is, causing lean condition?

Plugs might help. Why is it so lean on startup. Should be low 12,s till it warms up?

half way trough last winter my apex became hard to start when cold. It cranks sputters then starts and runs rough till it starts to warm up. Have afr gauge and is at 13.5 to 13.8 on start up. have pc3 on it and have not taken fuel away and co‘s are at 0. Have had suggestions, remove pciii, new...

Looking at new sled for 2022. Realize might be out of luck for this year, but getting new sled when I can. Ride groomed trails, currently on a 2007 apex 121. is Yamaha/cat dependable if left close to stock? I realize that skidoo will be down on hp but will still be plenty fast for me. How do...

Never thought of calling them. I’ll ask them what the spring specs are for the primary at the same time.

So what helix comes with sbm stage 2

Anyone know angle of helix for apex I have an assortment and don’t want to buy more if I have one that is close

So u are saying not same spring? Do u run stock weights stock helix? Does it still give good throttle response when cruising?

Looking for feedback from those who are using barn of parts/schmit brothers soft engagement spring. What rpm are u engaging at? What rpm is your final shift at 10700? Have tried finding info but always comes up for either viper or nytro.

I thought 2006 to 2010 came rich from the factory. The maps u have did they lean them down in the mid range. My understanding is because they are rich u don’t have to add fuel with an air box mod

Looking for an economy map or 87 octane performance map. Tried ulmer but no response when phoning or by email.
