I have a 22 gear and chain. was going to try it. I did a bunch of reading and it seems like it's a 50/50 opinion on it. on 2011 apex 128". I'm thinking I can clutch it to up shift faster to help reduce spinning.

i have done a ton of searching but still have this stutter when i pan it. if i feed it to wot its ok for a second then will drop rpm and sounds like a rev limiter. its been deep snow so im only hitting 10,000 rpm. if i go from 1/8 throttle to wot its just stutters and hits 9000. like its...

i bought a used 50hp holtzman kit. for clutching i used the conversion kit to polaris wieghts 80$. used 66 gram wieghts from a friend. set the fuel needle at one turn. the nos makes a significant differnece. its not nuts but its the difference between losing to an 800 and beating it.

just curious if anyone has cooked a head gasket or anything. i have a holtzman 50 shot on mine. its working well. noticed my anti freeze was low and am a bit concerned. i only hold it for 5 seconds. comments?

Any one try to replace just the crank sensor instead of the entire stator. The part number is RM00124. http://www.rmstator.com/en_ca/products/rm00124-stator-pick-up-pulsar-coil-yamaha-code-12-faulty-crankshaft-position-sensor-replacement-for-snowmobile Here is the link for a sensor only from...

Im pegging rev limiter a lot with clutching, gearing, excell header etc mods. Hard pack concrete trails the sled is just knarly . I love it. Its amazing. However softer trails i spin a lot and nail limiter. I know i can fix it with clutching but its perfect on the hard stuff. So I'm wondering if...

I did a quick google search with no luck. Im looking for someone that has been using these for 5000k. Im routinely changing my oem ones every 3000k. And getting tired of it. So lets hear it. How are they? Please no 2-3000k reviews. thanks guys

I googled it with no luck. Im sure u guys discussed it once before but i can't find it. Can u install power steering in a older apex? I know u would need a new gas tank ad well but is the ecu integrated with eps

Any one got a apex kit looking to get rid of? Thanks

Anyone have any experience here. i have lots of weights from doing clutching on my slowaris back in the day. u guys buy conversion kit or machine weights out. yamaha primary clutch pins are too fat

23 tooth top gear. in my opinion great cheap mod. pulls way way harder and its like 30$ I'm pretty confident u will like it

I have messed with older apexs from one end to the other. In my opinion the best mod by far to make u quicker on the TRAIL is ski don't precision ski. U will be amazed. Your apex has decent trail power but crap skis and rear suspension. These skis steer amazing. hope it helps.

I am in the process of re valving my mono shock. i would just send it away and pay to have it done but time is an issue and I'm in Canada. poor planning i know. I think i have an idea but would like some feed back or tips on what u guys did if anyone has done it them selfs. so here's what I'm...

Pretty simple plate, cut it out with plasma cutter.

I put precision skis on my apex, what an amazing difference. I bought them for 180 used with carbides and they we the best investment so far. Maybe I'm jumping the gun here was only one ride but I did follow a apex with yam a skis and watched it push all over. I could steer inside, outside...

I did ulmer air box mod, exhaust mod and put a fuel controller on it. i have the bottom and top and wot perfect at 12.5-12.8 air fuel ratio. but at about quarter to half throttle i have a lean spot of 13.3-13.5 riding at 90-100km/hr. it starts at 8500 rpm like a switch. 8400rpm 12.8 then 8500...

I did the ulmer air box mod with a hauck fuel accelerator. I got the hauck for cheap so I thought I try. I was racing 2004 xc 700 clutching and exhaust mods. That machine works well surprisingly. Anyway, no mod, one or two lengths in 1000" with the mod, same day, same trail I was waving bye bye...

I have researched and red tons of forms on here About gearing. My apex The 23 tooth hit 112mph and the 22 tooth hit 105mph in approx 1000' approx. People say theoretically that 22 tooth is good for 121mph but the sled doesn't pull it. still seems like it hits a wall. I thought 23 would go at...

Lots of guys say these apex is run lean. I put a wide band air fuel ratio gauge on And set all my tuning to stock. It ran 12.8 bang on the money stock. Maybe it's just my machine but stock is perfect. just a fyi. I am planning to do the airbox mod and I'm adding fuel that's why I got the wide...

I tryed to search for where u guys installed your sensor with no luck. anyone want to share how they did it? I have tig welder
