well here is my attempt at using a honda tranz as you can see the cables should be long enough
i am using the shifter and all out of the car
five gears with rev on the floor shift and 6 forward gears in the bike engine paddle shifted with air
-
I like the looks of that tranny! The cable shifter looks like it'll be easy to work with. When I did my last one, I had to make my own linkage out of a mitsu cable shift set-up....same basic result, just a lot more work. I'll have to get some pics of my new one up and we can compare notes.

we cut the bell housing off with an air saw and a sawsall blade. it didnt take long at all
i thought at first that i might try to use the bell housing as a case like a harley primary to keep the drive chain oiled but its just to big and bulky so we removed it. the diferential part of the trans from seal to seal were the splines are is 6 1/4 inches wide once i weld the 930 flanges to the honda input shafts it should be 9 inches wide thats a guess. ill post more on that this week with pictures
i hope this might start somthing new. and bring the cost down on f-n-r boxes i think 3500.00 is way too much.
besides the posability of having 36 gears and six reverses is so cool to me.
its also my belief that if we as a whole in the sand rail ind. could bring down the cost of buggies it would further our sport and create more opertunities to use buggies as a way to earn a living in more places than just out west.

here is some progress pics hope everyone likes what i am doing
-
Have you calculated/graphed your rpm/mph in all gears?
-
I belive he sais he's running the honda in 5th...back sprocket seems huge to me. My golfcart was 1-to-1 with the 5 speed I had. 26" Bighorns and 5th was a bit tall. 4rth would smoke the tires in the 1st 3 gears of the gixxer 6 motor!

That's my point.

the sprocket in the pic was just for mock up i wanted to make shure that i had room for a bigger srocket if needed.
the one i will actualy use is much smaller.
remember i dont need alot of top end the honda tranz is used to being turned at max of 6000 rpm in the car.
the r1 revs to 15000 rpm so a much taller gear wont hurt me to much. if i only had a top speed of a 100 mph i would be happy. the only thing i wont like is that it would make all of the gear shift points real close.
-
Your bike engine has a primary internal reduction before the tranny input that will bring your bike countershaft rpm down to somewhere around max of 7000 rpm tho. You do not see crank rpm at the tranny output.
-
i thought of that when i typed the responce
evan though a 1000 rpm is a huge diffrence i have a stock 600 kawasaki rear spocket its still on the bike we just had given to us it is way smaller
i am also concerned with chain length short chains get hot and ware out.
the nice thing about what im doing is the chain will be real easy to change.
i cant go much bigger on the engine
-
You NEED to calculate the MPH in each gear with whatever sprocket ratio yiou are considering. Yopu are going to be disappointed the way you're going about it. You need approx 1:1 chain ratio. Maybe a bit lower but not much. Any rear sprocket will likely be too low. WhAT is the primary reduction of the engine ypu are using? What is it's redline?
-
2001 r1 yamaha 1000 15000 rpm red line
running 1:1 would meen using a front sprocket on the rear i think that would be to tight.
on the chain.
stock 1994 accord 5 speed
-
Your gonna want the largest front sprocket you can fit without rubing a hole thru the case, maybe 20 or so. Yamaha site should be able to give the gearing for the motor, and I would shoot to use 4th in Honda, would allow little larger rear sprocket. But I'd bet 20 front 25 rear with Honda in 4th would be real close. But you'll need the ##'s.

There's a difference between thinking and calculating. Get the calculator out.
-
I ran 1-1 on the golfcart.. GSXR600 and the L3 Honda 5 speed. Couldn't hammer it in 5th...bike clutch was wanting to slip some. 4th was perfect, not sure if I was leaving anything on the table not 'using' 5th. A calculation would be great...I'm pretty sure the RC51 will do better at the same ratio and a bit taller tire, the golfcart had 26" Bighorns and I hope to use 30" light truck or auto tires on the RC.
-
thanks for all the info if i have to i will use a hevy duty clutch if avalible.
here are some pics of my swing arms fabed out its coming along great
what is nice it will be easy to switch to micro stub hubs when im ready
i want to build these and sell them take note of the car o liner frame rack i have for a jig table
i also have a table i welded togther for just building the frame. i put it on a motorcycle lift makes it nice to raise and lower
-
Those look just like the Desertkart trailing arms?? If I'd known you wanted to use them, I could have sent you the bent ones I have. 1st Time you get 1' air the will bend and top of tire will be leaning in. Try putting some light plate across tubes or a diagonal. Looking at arms from back, they twist clockwise.
-
thanks for the heads up
-
some pics of the front
-
What kind of shocks are you going to use on your front a-arms.
-
Your making some progress. :) :) :)
-
fox coil overs all around i plan on weighing the frame wonce i am done fabing
should be 18 to 20 inches of travel
any suggestions ?
-
Just an idea for you, You could run Fox 2.0 air shocks and save some $$$. Looking at your car, I don't see the need for running coilover shocks IMO. 8) 8) 8)
-
The man on DTS to talk to about Fox air shocks is DS race. He knows those shocks inside and out.
-
the arms and frame are all out of 1 1/4 inch od DOM tube its pretty strong stuff
i may just add plate to the arms if they bend..... i can straiten them thats a car o liner frame rack with a measuring system the frame is on i done think you can get a better jig to build on i didnt build the frame on it i got it after but it came out so square useing the jig table i welded together myself .
every thing at this point is just tacked and i am adding bracing to the front arms too.
-
Cool! :D
What's the wall thickness on your 1 1/4 DOM?
-
i was told coil overs were cheaper on ebay lol
i will do the research before i buy.
im very happy with how everything is coming out....... its awesome .... you know when you get that feeling its just the way it was ment to be its cool....
-
That it is! ;)
I know the first time I drove my sand car, I had a ;D ;D ;D ;D ;D what lasted a week!
-
the wall thickness 1.25
-
Won't you mean .125 ???
-
yea that happend when i built the single seater
this is diffrent.... Its not plans i bought its my own design ...bend tech pro.. i have the latest upgrade now it does plates now too i hope to have a plasma table very soon i like the 2x2 torche mate but i want 4x4 with the mill and engraver
-
the frame calculations for weight in bend tech said 330 ponds w/o sussp. bare frame im thinking 1200 lb finished
-

You might be thicking a little heavy. I'll bet is around 1050 lbs.
-
well that will be great i hope your right

something i found out the other day i have a source of honda transmissions for $200.00
the guy races a honda prelude in the dirt he told me the prelude trans is worth alot more that the accord they lok identical its the gearing the accord has higher gears so its less desirable to the street racers
and with all of the conversation on my thread about gearing and running one to one thought it might be a help to mention this info
it was my luck i bought a accord trans lol
-
Coilover are cheaper, but that doesn't include the coil springs. I post a link to some fox 2.0 air in old blue color, $125 ea in 12" and 10". They are probably gone. Its looking good, keep pics a coming.
-
carl I think he's out of cheap shocks now and btw they are a liquidating those shocks for a mc buggy builder that went under that is why they were so cheap. the valving in the 12's was 65/85
-
what is the web site were they are liquidating shocks i might jump on that

Try emailing tommy@polyperfomance.com he was giving a disc off ebay. If I had a few $$$$ I'd bought all of them. About $100/shock less than what they go for.
-
do you think they would handle 20" of travel
-
do you think they would handle 20" of travel
Yep, I have 2.0 air shocks on my car with 22" of wheel travel. It's all about how you set the valving, oil amount and pressure. 8) 8) 8)
