    2014 Switchback 800 (standard model) clutch recommendations?

    Friend just picked up a used 2014 SB 800, it has the stock Ripsaw II track and we put in around 106-108 studs in it down the middle...that's good enough for him. Has all stock clutching - and his budget is tight, any recommendations for clutching that would help out to be worth it?

    Leaking coolant line below PTO side power valve...

    I'm the 2nd owner, but to my knowledge it had not been. Didn't look like the spring clamp had ever been touched.

    Leaking coolant line below PTO side power valve...

    Keep in mind I have the fuel injection line the way it is because the only way I could get at it to tighten was from the top.....any other direction it would it the power valve housing!

    Leaking coolant line below PTO side power valve...

    I noticed the other day some antifreeze under my 2016 SB, sure enough that coolant line under the PTO side power valve was leaking a bit if you moved the line around. That OEM spring clamp just didn't do its job well. I installed a fuel injection clamp I had around, I'm not a huge fan of the...

    Proper clutch alignment

    What does/can dealer do to correctly test TPS and valves synced? All done via digital wrench?

    DYNOTYME II !!!!!

    How did the BMP pipe due cold? In other words, was it lower on HP until pipe temp went up? Thus in real world conditions one might expect it to not pull as hard or accelerate as quick as compared to the Jaws pipe which had similar HP cold and hot? Nice work guys. Thanks for sharing!

    Performance Q & A with Joey from Bikeman

    Great info as always Joey. Thank you! When do you anticipate you'll get on the Dyno to do a stage build with the new Y-Pipe and start providing the updated Tunes?

    Not really sure to be honest, never had a real good long run to test it out last season....

    OVERDRIVE P85 PRIMARY

    I would like to try gearing down, but I am concerned it will slow me down!

    OVERDRIVE P85 PRIMARY

    If machining your primary for more overdrive, but keeping stock gearing (22/37 on my Pro-S), is there any impact to low end and mid range performance? If I understand correctly, there would not be....?

    Pro-XC 144 switchback

    What do you mean by "Turn to turn the 23/40 is better"? I thought the most efficient gearing combo (if gearing down a SB Pro-S) was the 24/40 gearing over the stock 23/37 gearing?

    Belts

    So, the Gates CF 46C4387 is supposed to be 43.87" pitch length if I'm not mistaken....so, that would be to long correct?

    Axys head.

    Correct, not released yet....but they have done some dyno testing on the prototypes to prove there is power to be had - how much? TBD....

    Axys head.

    BMP has the BD Program to run their head with pipe. I believe they will have updated tunes to run with their Y-Pipe as well. I hear about zero from performance shops on ported cylinder's on the 800 H.O. engine...

    Axys head.

    How much did the BMP Head impact the HP/TQ curve throughout the curve?

    Stock Gearing Clarification

    With the Cobra track it came with 22/37 gearing. Just had track swapped to a Hacksaw with a 2.52 driver so put back in the 23/37 gearing. Not sure why they'd have different gearing between a Cobra and Ripsaw II?

    clutching machining?

    I talked to them, they typically don't - you can upon request.

    Bolt on HP mods. Have pipe whats next?

    An easy bolt-on (or easier) if you don't have electric start! You have to loosen up steering post and loosen up electric start motor to get Y-Pipe out....

    clutching machining?

    Do you feel adding more overdrive to the OEM Axys Primary clutch is worth it? Have you observed a performance difference before/after machining in more overdrive? Thx!
