honda trans chain drive

[magnum4598]

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?

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.
