[Closed] Pike Issue – Air Trapped in Lowers?

I know there’s a Pike thread pretty much daily, but I’m struggling to find an answer to my issue and would like some advice.

Recently changed the travel on my Pike RC from 130mm to 150mm. Since then I’ve not used full travel in 7-8 ride/350km of riding.

I put it down to setup, which I’ve been playing around with, until last night when I decided to let all the air out to see if I could actually get full travel, which I couldn’t. It bottoms out at 25 to 30mm short.

So a bit of googling suggests that I may have trapped some air in the lowers when putting them back together, is this is reasonable explanation? All other functions, rebound, compression seem to work as they should.

If I’m right, to save having to strip the fork down, is the ‘burp’ trick with a cable tie the way to go? From what I’ve read it just a case of carefully sliding the tie between the seal and stanchion with the forks aired up and fully extended and I should hear the air escape.

Any help appreciated 😀

Does indeed sound like you have air trapped in the lowers, small cable tie past the seals (both legs) will release the build up.

definitely worth a try. it's not trapped from putting them together, unless you did it in a crazy high pressure atmosphere, but it's leaking from the -ve chamber into the lower leg.

Did you keep the valve pressed open while you compressed them? Otherwise the spring will still build up towards the end of the travel

Thanks all, I'll give it a go tonight once I've tried what legend suggests, as I didn't hold the valve open whilst compressing.

bigjim, hopefully not the case and pretty sure it's been the same since the rebuild.

So the cable tie trick did naff all and neither did holding down the valve whilst compressing.

Whipped the lowers off and the air shaft moves up and down freely but the damper shaft only goes in about 125mm ish, so looks like there's an issue with the damper 🙁

Bit strange that the rebound and compression work, but an email to Loco in a bit it is then!
