override N1-5

[part-time]

Ok lets say I have a regular 1-5 Ndown and I wanted to just cruise from my back yard to front yard....is it ok to pull in the clutch to upshift even though I'm not at WOT or should I just stay in first ....One more thing.. can fifth gear be backloaded if there is no sixth gear..thanks!!!!

[Phelps]

if it's a full override than treat it like one. is pulling it from the back yard to the front going to be a issue to just use first?

 

i treat my duneable like a full override. never really apply any backload in any gear and never use the clutch up shifting. you can up shift under light load......

Ok thanks..Its not an issue at all, I was just wondering ...I do shift under light load at times but never pull in the clutch and never back load it...but thanks again just wanted to make sure

This might be dumb but I don't understand what backloading means. Can someone give me an explanation into how these work?

letting off the throttle and using the engine to slow down is backloading a transmission.

[Badbar88]

So my understanding is you can backload a duneable overide? Does a duneable mean you can ride it like a normal trans if you want but can also shift under power without the clutch?

[Jereme6655]

yes and no.......the dunables are more "forgiving" when it comes to the incodental split second of backloading.....but you still shouldn't try and backload any over-ride.

Thanks for the info, been wondering how these work for a while.

overrides are the best mod ever! I love mine and wish I wouldve done the mod earlier on. I have the 1-5 N down duneable and if I backload it, its by mistake. Before I go race, I go off to the side and just cruise and click up through the gears to make sure they are oiled etc. After that, its game on! Only time I use the clutch is when I let out of it when I start and at the end of the strip when I pull the clutch in an let it coast to a stop then I click all the way down to N and then click up to first and head back to the starting line. I dont downshift mine while Im coasting to a stop either.

I'm also new to the overrides, If your not drag racing all the time and you actually want to ride is it ok to clutch and downshift if you make sure you rev match it when letting out the clutch? That wouldnt be putting any backload on it if your timing was right.

With a duneable, you can backload a little at lower RPM. What you DO NOT want to do is be 3rd 4th gear wide open and let off of it and let it coast without pulling in the clutch. Backloading causes a tremendous amount of heat in the tranny. When you backload, the heat builds up on the shiftforks and weakens the shift forks causing them to bend. Duneables are more forgiving for backloading. When I first got mine, I was learning how to run it and it wheelied all the time and I would let out of the throttle for just enuff to get the front end down and then wide open again. Yeah thats backloading the tranny, but not for a long period of time, its not good on one, but the duneable allows you more room for error. I go by one rule, if you're not on the gas, I pull in the clutch. Like I said earlier if yo're in 1st gear putting around, yeah you'll prolly be fine letting off the gas etc. But, if you're wide open, and let off, you wanna pull the clutch. An override will easily give ya two bike lengths. The best way to describe an override when it shifts is ORGASMIC. It feels like someone is punching u in the back when it shifts. It only takes about an hour to break urself of grabin clutch to shift because the tranny will make some weird sounds when u do grab clutch to shift.

i backload mine every chance i get, no chewed up forks, bent shafts or broken metal pieces here.....

Yeah, im sure u dont.

When I got my dunable wcr told me not to backload it above I think 6 grand. Theres more pressure on the forks holding the gears in place on a override, so you don't wanna backload. It'll pop outa gear or worse yet 2 at the same time. I think that's what makes them go boom. Just cruising around the yard shouldn't be an issue. Pretty sure you wanna downshift with the clutch. I've done some stupid stuff on mine getting used to it and it hasn't grenaded yet.

in my limited exp with overrides.

 

a std override or non duneable or non spring assisted uses the actual rotaton of the transmission to work that is yea it will shift on your bench due to design but to work right it needs to be moving in a forward direction with power from the motor turning it NOT reverse on the trans from not being on the power.

 

the gears are flat on one side and angled ont he other and when you backload the dogs back up the ramps and push the gears out of gear now the only thing holding the trans in that particular gear is the shift fork so all that load and stress ges right intot he shift fork.

 

on dunealbe or what i would call spring assisted the trasn AND springs actually move the gears when you shift SO you CAN down shift it in any gear if you are rolling forward and the gear behind has a spring that pops it back out of gear.. the ramps are all there and the backloading is still the same as a STD override.. its just really hard to have it in 2 gears at the same time from downshifting if your in an overriden gear..

 

i am still trying to figure them out completely and its not rocket science but its not super easy. i understand the theriorys now and kinda how they all work. i even modify the WCR's transmissions to feel differnt when they are shifted and its much easier to tell what gear its in weather N or 5th.

 

overrides are a LOT of fun and a real necessity in a drag bike. if youve never been around one its best to have someone that really knows how to ride one kinda guide you through it while you are riding the bike.. all the over's i have installed i also try to do a "training" session to help them understand them better..

 

instead of a piece of paper in a box that says springs go here, dont down shift above 6k rpm.
