I just came across this thread and hats of to you Dustom for this amazing effort. Wishing you all the very best for the Bonneville attempt...
Now, on some feedback - I would suggest you check the aerodynamics of the entire bike-with you on board- esp if you are attempting to set a speed record- wouldn't a crouched position be better and lot less resistant?
Also, you've worked really hard to setup the bike, don't undo what you have done by trying the burnout against the wall- the stress that you are putting on the front shocks and handlebar - might not be ideal in the long run.....esp if you are looking at high availability during the high speed run!

You came across at the right time, thanks at lot for your inputs. I plan to make a totally road worthy vehicle that would be good enough to challenge for the record in its road worthy trim. Hence the upright riding position. Present record for diesel motorcycle/bio fuel motorcycle isn't too much. What sort of aero we would require is still to be figured out. Also burnouts against the wall do put a lot of stress specially on frame and front forks. Philosophy behind- if something is going to givein , it better do so in my den.
Also whenever I do manage to save money enough to take it to salt,i would build that bike from scratch with lessons learned from this prototype.
Loads of videos coming In, of one of our test run, starting from tonite. Loads of HD videos also capture d.

Saturday night we took motorcycle for road test . I am so glad to tell you how beautiful the whole experience was.
Bike felt at home on the road which had speedbreakers at every km.it was industrial area of haridwar(SIDCUL). it was firsttime we took the bike out on road after rear suspension and sub frame were redone, also now it runs with verna stock air filter. although that air filter is itself bigger than most bike engines and i was struggling to find enough room for it . somehow relocated couple of electronics and things and air filter is on in its stock form. Changes to rear sub frame have resulted in much much better traction and improved rear suspension response. earlier it was a lil too easy to get into wheel spin. much better traction under heavy acceleration this time around.
Nothing sticks out of either side of the bike and overall dimensions compliment the whole bike very well. seat hight is just 26" off the ground and extremely low center of gravity makes the bike so easy to ride and flick side to side effortlessly. I will be posting videos from helmet cam,where you would be able to see acceleration like never before, stable vibration free ride quality and its flickability. diesel clatter is audible at idle,once the bike gets moving its quite sober. couple of times i had to make U-turns ,taking u-turns on 2lane space without putin your feet down in 3rd gear and then seemlessly get going is just awesome. once the engine gets to 2000rpm acceleration changes from seemless to shameless. I mean what on earth is going on . Big cruisers are not suppose to do stuff like that . hold on 50kph in 3rd gear , faint turbo whine is heard, replace your nuts with steel ones and go for full acceleration. next thing i experienced was the most awesome moment of my life . whatever it was ,my hands and legs were shaking for quite some time out of fear or some feeling like that. 50 to 100kph in 2 seconds after which you shift to 4th and the bike just keep getting faster as if world is in fast forward. cruise at 55kph on idle in fifth whole day long. there is sooooooo much torque that i got going from stand still in 3rd and slowed down to clawling speeds while going over speed breakers and just let the clutch go. no hiccups no jerks ,engine gets into survival mode ,injecting more fuel and getting to awesome torque levels even on idle speed.


For most of the time i was in front of the chase car which was my another D4FA 1.5l crdi. some HD Videos were shot from chase car aswell which would be available on youtube shortly. in present from they are just to heavy to be uploaded,i will have to lower there formats and size.

These are some of the final stats:
Power- 110bhp
Torque- 240 nm
Power/weight - 358bhp/tonne
Torque/ Weight - 781NM /tonne
Weight - 307kg ( ready to ride)
Wheelbase- 68inch
Rake - 34deg
Ground cle- 6"
Seat Hight - 26"
Transmission - OEM Hyundai Verna 5 speed manual with Reverse
Clutch - OEM 13" single plate dry diapharam type
Clutch actuation - Power assisted
Fuel capacity - 14ltrs diesel + 8ltr PPO/SVO.
Max fuel efficiency - 28kmpl on low sulphur diesel at 55kph.
Max speed - 207kph
Acceleration as tested - (0-100kph in 3.8 sec), 50-100kph in 2 secs.

although this engine has been under some weird fuel tests but is still behaving quite nice ,no smoke, no power loss etc . the newer U-2 series 1.6l engine from hyundai is dimentionally same,with same weight but with more power and torque. it also has balancer shaft in crank case which makes it one of the smoothest unit in segment. best news is hyundai is selling it in open market as Crate engine for around 4400$ and transmissions are also available off the shelf

More to come!

Dustom_99, this is one of the most interesting projects I've come across!! Is it possible for you to elaborate how exactly you have solved the problem of shaft jack on the motorcycle? I'm sure a lot of us would be extremely curious about the design ideas that went into the making of this beast.

Cheers,
Rahul

PS: Get rid of that hideous rear mudguard!! It kinda ruins the build-up of the previous posts. What were you thinking?????

[dustom_99]

I obviously cannot tell you in details, developed a mechanism which moves a smooth link in and out of a brake caliper located under the gearbox, pressure inside the caliper's cylinder is governed by torque available on drive shaft aswel as movement of suspension . if there is too much torque being send on the shaft,and shaft jack begin,caliper arrests the flat link connected to rear suspension. practiacally keeps the bike behaving like a hard tail while it is in 1st gear.
3rd gear onwards it does not do much except provide additional damping while under hard acceleration.

although it does not make the bike a real hard tail,if you manage to hit a pothole or bump or maybe a speedbreaker, compressive force from the irregular surface counters the shaft jack by itself and releases the caliper instantly.

bike now has enormous traction off the line and makes good use of that flat profile tyre in acceleration.

all heavy components are located very very low on the bike, if proper motorcycle tyres have any advantage in handling dept over the flat profile car tyres, i am in for a treat because handling is sweet already. bike feels very light and nimble while on the run.

i think i have told more than i should have.

and yes i agree i was out of my mind as far as that rear mudguard goes. its gone for now. rite now riding around with rear mudguard frm my previous bike.


anyway guys suggest me a downloadable convertor that would convert video formats from MPG to MP4 or something like that

falcon 2 Acc - YouTube

watch falcon 2 to accelerate to 100+ several times.
watch for 4th gear acceleration in the end from idle at around 40kph to 120kph in 4th gear (at playing time 2.42- 2000rpm) by 2.47 secs it crosses 3600 rmp. speedo meter is little bit off, shows slightly less speed than actual although not too much difference.
at 2000rpm speedo is at 60kph,at 3500 rpm its at 120 kph, time taken 5something secs.
and i am still wondering, was i using full acceleration?

also watch handle bar stability, no wobbles,no vibrations,pretty decent ride for a home made bike at all speeds.

Totally jabardast, dude! I have been tracking your thread for some time and hooked on it. The trials look great.

What you are doing is fantastic and I wish you all the success you deserve.

Where (which track) do you plan on doing the record run? Have any sponsors raised their hands for you yet? Where and how do you intend to do stress testing for the bike before you take her to the track ? I presume you will have to arrange for some officials to come and record your runs too. It may prove to be a costly affair...perhaps costlier than what you have incurred in building the bike so far.

[LP640]

Man that is a mean machine.. you seriously need to respect its power.. so much power that if you ask for it, you need to be sure you can handle it!! Cruiser? Super Cruise?? Its actuall a MEGA Cruiser in making!
It looks so stable when you take off your hands! And then is the power, 40 to 120 in no time without changing any gear???

Hats off to you dedication, passion, knowledge and hard work! Great work.
Make sure you wear proper riding gera all the time. All the best! Ride safe

I would be talking it to Joligrant air strip near Dehradun by end of this month i guess. i would be able to arrange for the strip in very early morning (0400hrs-0500hrs). There we would try and hit the top speed in that one hour window. present gearing would not allow us to break the world record ( top speed 207 in 5th gear),although i have an option of 6th gear within the gearbox, but i am yet to figure out a mechanism to engage it while the vehicle is doing about 150 already. there is absolutely no space left for addition of another selector fork.
so for now i would see how the bike feels while doing nearly 200.
I can assure you that World Land speed record is well within our reach for Diesel / Bio Fuel Motorcycles as far as power is concerned, as now we do not have any technical problem in some of the key areas. there is absolutely no restriction on power we can use. Using 2l or even 3l V6 engine is not out of reach as far as breaking the record goes.

But still i want to be in that list with a motorcycle which is capable of daily routein running.

I am quite sure very soon we will see turbo diesel cruisers in the market, I mean the segment is wide open.
Yamaha and Suzuki are already Investing into R&D of such motorcycles.
If Factory Made cruiser Hits the market with 1400/1500 or a 1600cc Turbo diesel inline4, all Gas sipping cruisers (No matter who makes it in what part of the world) will kneel down right in the middle of highway and beg for Mercy!

I havent recieved a call from any kind of sponser,i do recieve calls, but all they want is to offer me a job. Indian audience/companies do not connect with speed fever, all they want is to sing and dance. Copy west and when they cant even copy it properly , call it Fusion.


Its Far Economical to take your vehicle to Salt flats during Speed week Than it is to arrange for officials at your desired location. So I would take that route.
I Have sucessfully made the bike, but the road ahead is going to get tougher for me. I mean Financially. Expenditure i have had till now is actually less than what R&d Engineers in indian Automobile industry are paid for coming up with new graphic stickers. But Future does not look too Rosy , because Engineering part is over now, i have done what i could with my very limited resources. Things and tasks that should follow the engineering require massive amount of dough.
So i will Get back to some kind of job,may be an assembly line manager which i have done in the past, save money for a few years and wait and watch how things go.



Thanks LP640,yes Ofcourse it is a mega cruiser, whatever times we did in those videos, are set for fall further. primarily due to two reasons. 1. Clutch was slipping all the while bike was on boost.(Due to Improper assembly of Foot Clutch Pedal) there was an extra long bolt , and was preventing Foot Clutch lever from ataining its fully released Position.
2. Rubber Hoses I have Used for Air intake are made by joining several sections. From Air Filter - turbo, Turbo - intercooler , intercooler - Inlet manifold , all of these are made by joining atleast 3 pieces. Air flow would get much better with one piece hoses.

[LP640]

Nice to hear that times will still decrease! Also when you go to the airstrip I wish everything turns out really well and safe.. touch wood... but still test remember to take riding kit, a full first aid kit and some friends along.. just being prepared for everything.

[ishotmydog]

Holy Smokes Man! What a project, What a Bike!! Hats of to you.

Cannot wait to see the final product of your hard work and determination

Any one willing to invest in TDi Motorcycles production model? Got a quote from hyundai for U2 1.6l , shipped in ready to start start for 4400$.also available 1.4l 90 ps from them.transmission also from hyundai. MJD 1.3 can also be a contender.Procuring in larger number will significantly reduce the cost for engines and transmission.
I am sure once the bike goes under a CNC it will be lighter and with better build quality. Front End to be Imported from UK (Rocket 3).
Make 3 bikes, get them Homologated (India or UK) , and limited production run of 50-100 bikes can be started (no assembly line required,CVO style), Each unit with 1.6l u2 hyundai to cost around 4.5 -5 l bucks.
Is this thing even Doable? Graduating from Home made bike to Production cruiser?
suggestions please!
