trickedcarbine Posted February 17, 2013 Report Share Posted February 17, 2013 A few years back Greg at WCR messed with the extreme dunable transmissions and ultimately it was a bust because only a handfull worked the way they were intended to. Are there any other builders still toying with this concept? If not I think I'm gonna do a 1-3 override with M 4-6. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted February 17, 2013 Report Share Posted February 17, 2013 I've been beating the fuck out of three Redline duneables since 2005. Never had a problem. Call Redline. Quote Link to comment Share on other sites More sharing options...
mailman Posted February 17, 2013 Report Share Posted February 17, 2013 Make sure you bring a back up bike on your trips. I blew up 2 or 3 of these "extreme dunable" trannies and my whole trip was ruined. Plus I got the added benefit of tearing my cases apart when I got home from "not riding much".

sleeper06 Posted February 17, 2013 Report Share Posted February 17, 2013 I still have three of these extreme dunables going strong in my area,but I had to rework the drum and adjust spring pressures so they didn't chew shit up,they were a good concept poor execution .you want bullet proof call Robinson transmission but your gonna pay its not like wcr pricing.He very rarely answers the phone and call backs are after business hours.you also can't just drop shit off he deals by appointment only Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted February 17, 2013 Report Share Posted February 17, 2013 Or you could try Redline, whose duneable overrides I have been abusing the fuck out of for many years in BIG ass motors. Quote Link to comment Share on other sites More sharing options...

camatv Posted February 18, 2013 Report Share Posted February 18, 2013 ok maybe a lil off subject what did the "extreme" involve differently than the fork eating duneables... i have a "concept" as far as a spring assisted rider trans but have not started on it yet. i'm working on a trans "dyno" to help with some of my idears... that duneable may be working fine but unless those goofy springs are PERFECT it will eat shift forks BUT by the time you realize a fork is damaged so far it wont stay in gear usually the gears are jacked up too.

Redline Racing Posted February 18, 2013 Report Share Posted February 18, 2013 I agree with camatv. Anyone who understands an override will understand a spring will not support a backload. Dunable transmissions are slightly more forgiving but by NO means stock. Forks need to be replaced yearly or at least inspected. I do dunables but I do not tell people they are not without there issues. Quote Link to comment Share on other sites More sharing options...
possum Posted February 18, 2013 Report Share Posted February 18, 2013 @Redline, tyler says he abuses and beats on your dunables. Sounds like he backloads it? What can you do with your dunable. Backload under 6000rpm? Or never not for a second? Quote Link to comment Share on other sites More sharing options...

Backload under 6000rpm? Or never not for a second? I am speaking from years of experience with Redline duneables.. I have had 2-4 duneables in a 10mm Cub, 10mm DM and two 18mm DMs. Every single one of those transmissions have been shifted up and down, with and without the clutch pulled in. I have been in the middle of a run and accidentally landed on the shifter. I have been pissed off and slammed the bike down into first gear not using the clutch and just coasting along. I have done literally every single thing you're NOT supposed to do with an override. NOW, I am NOT telling you to order a Redline duneable and go out and TRY to break it. What I AM telling you is that Redline duneables hold up to some pretty major abuse. Anyone that has seen me ride in person or seen my videos can attest to that. Keep in mind, if I break one of them, I am NOT running to Redline and crying that it broke! If it happens, it happens.. Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted February 18, 2013 Report Share Posted February 18, 2013 I have used and put in few trans that I know redline and cam would be interested in,they were full 6 speed auto they had no spring anywhere to hold forks,billet sliders were manufactured for the shaft and time area was taken off the pads to ease shifting but there was no back cut on gears so it doesn't chew forks,I started to fuck with different ideas but as you guys know time is at a premium and my Bridgeport mill,lathe,two tig machines went down in flood.So pretty much I got fucked sandy and now have no time or equipment Quote Link to comment Share on other sites More sharing options...

You will wear shift forks, gears male and female dogs. If you go into a dunable tranny knowing you will wear parts you will love the tranny. If you think it will never need attention you will be disappointed. I tell people if you are not capable of checking your own shift forks you probably don't need a override.

trickedcarbine Posted February 18, 2013 Author Report Share Posted February 18, 2013 Hmm. Cam, you ever do a 1-3 over ride with M 3-6? It is for a flat track bike and I'm thinking it could help get the holeshot. I do use engine braking for corners though. I usually come in to the turn with 6th wound out and just grip the clutch and drop it to 5th or 4th depending on how tight the turn is. As soon as the gear is clicked down I let off the clutch and it almost pitches it immediately for the set up. Once it is aimed at the apex of the turn I'm full on again.

Apparently it was supposed to be an Over Ride that could be back loaded or downshifted clutchless with out letting off the power and pulling he clutch. Basically ride it like a stock cut but beagle to upshift flawlessly Quote Link to comment Share on other sites More sharing options...
