Hey guys, I have a nice low miles 1999 yamaha mountain max 700 with bender triple pipes. The rest of the sled appears to be stock. The clutch engages way too early. I am new to sleds. I have no idea what I’m doing. Just know that a clutch shouldn’t allow the track to turn until more like 5,500 rpm. Mine hits at 1800-2000. It’s a boggy dog. Anyone happen to know what springs and what not I should run for optimal performance on this machine with triple pipes riding in areas from 5,000-8,000 feet elevation?
Looking for specs on a custom clutch set up
- Thread starter Bondra131
- Start date
Here is what I found worked best for my MMax triple with Bender pipes. The engine RPM at full throttle should be 8500 rpm. Engagement rpm should be between 4500-5000 rpm. The "Totally Yamaha" website also has numerous specs that are posted for users. Lot's of great information on that site as well.
- Primary weights – stock clutch arms 8cr / 38 grams
- Inner rivet hole – 3.6g
- Outer rivet hole – 2.4g
- Primary clutch spring – Yellow/White/Yellow
- Secondary clutch spring – green @ 80 degrees wrap
- Stock secondary ramp
- Main jets 136.3 all three carbs.
- Pilot jets 57.5 all three carbs.
- Stock jet needle clip #2 position
- Pilot fuel screws / 2 turns out
I will give it all a try. Very detailed! I’ll trust that. Thank you. Much appreciated. This thing is already fun. Going to be a real blast once it’s dialed. Might even throw vforce reeds in it
