trike build

[terry t]

hi all latest update.afther toad sorted out the running. i got it mot.then sorted out the over charging.it was ready for the big test on the dual carriage way to see how it handled with these forks

trike build

started of slow in 20 mph zone no shakes or pulling increased speed slowly alls fine onto roundabout. not fighting with the bars likebefore
now on the carriage way 40mph ok 60 mph ok 70 mph ok no pulling can hold one handed drives in a straight line even when backing of the throttle.
went for a run it handled fine at all speeds and road conditions i could trow at it .o/a iam pleased with the out come of the  build and looks of the trike not sure what colour to have it painted. now sorting out my next project
 terry

Those of you that read my post about heavy steering and wheel shake.well i had these easy steer yoke extenders made and the out come was better than i expected.no wheel shake drives straight and handle well into bends and round abouts.i set a video camera up o the handle bars and filmed it through the town and part carriagway look at the link on you tube

Bet your well impressed terry t, I'm well jealous, Can't wait to get mine done now i've seen yours on the road, Looks to handle really good to me. A big thumbs up to ya terry g6

[terry t]

Thanks g6.the trikes been on the road since jan 09. it only when you ride then you find the problems.mine had heavy steering and steering shake.when you went into a bend or a round about you had to hold on tight other wise it would pull straight.so i had these alloy fork extenders made.can only say one thing.they work
the camera was set low to try and show the speedo and a view just as back ground to show how the steering reacted at different speeds

A or B diff
As it was a nice day i took the trike out for a good run.
it ran and handled fine but
now no matter how had i tried i could not get it to go past 65mph
the question is what diff 
the originale bikes final drive was 3.400 ratio on a 25" o/a wheel
its running now on a reliant b diff with 2.78/1 ratio on a205/55/15/ 24"o/a wheel
i have got an a diff with 3.23/1 and 205/60/15/25"o/a wheel
question is what would be the best combination i don't want the speed but would be nice for over taking etc

Theres not much difference in final drive (Bigger tyre/lower ratio, smaller tyre/higher ratio) if anything the combination you have now should be the slightly the best. Where is the speedo drive? front or rear?
get someone in a car to follow you at a given speed (Say 50) and see if thats out.

[terry t]

Hi cunningplan.the speedo is drive is on the front wheel.the speedo seems to to be ok as when in traffic in the town 20-30and 40 it about right.it just seems that its got a speed governor on it stopping it from going past 65

i would see what the rev counter is saying at 65 terry

i would see what the rev counter is saying at 65 terry

just checked the video. its about 3500 4000 rpm at 65
i noticed it did touch 70 mph at 4000rpm in the video but that's with the wind behind me hasn't done it since

[zakboy]

iv never used a b type axle on a motorcycle engined trike, my gs had the type A  3.23/1axle im not a speedster but could get it up to 80 before i chickened out, but prob would have not done much more than that, the wheels had a over all hight from the ground of 21 inches

Dont know if this is any help, its a bit from one of Thunderaces post on BTW doesn't mention A's or B's but as you can see there can be a huge difference depending what you have


Old three piece case Regal axle was  4.375 : 1,
750 Robin used 3.545 : 1   
850's Robin & Rialto   3.23 : 1
yellow top Rialto  super tall  2.78 : 1  final.

if you know what ratio your gears are from first to fifth, if you use this link you should be able to work out what  set up would be best http://www.kabamus.com/garage/gears.html

Hi nabsim.yes i have got that info. my thinking was the goldwing diff was 3.400 with 25"wheel
i am running 2.78 with 24" wheel
if i got hold of 3.545 that a lot closer to the original diff of 3.400

Hi zak. according to this with the diff and wheels Ive got
at 3500 rpm in top gear i should be doing 95 mph
at 4000 rpm in top gear i should be doing 108 mph
i will be happy with that
