Hawg-TY 10hp diesel mini bike & pics

[numscul]

The gearing on the bike is 50 tooth rear sprocket and 14 tooth front ...i don't think the gearing is the problem ...i think the clutch springs are too strong... Here are a few pics
i just took for you guys ....and i just want to thank all you for your advice,input and ideas it made things a lot easier to be able to talk to you guys
The only things i have left to do is remake and mount the chain tensioner because the first one broke and fell off the bike while i took it on its first full throttle ride and the second thing is to mount the dummy tank
and as you guys can see it smokes like a locomotive on meth

wow, the bike turned out awesome, isnt your leg really close to teh exhaust though? Doesnt it get really hot?

 

[Bluethunder3320]

love the diesel smoke pouring out behind a mini bike... dont see that often

badass

 

[numscul]

The pipe does get a little warm im thinking about putting a heat shield in between the pipe and my leg but its not unbearable but iv only only rode it a few minutes at a time so it will get hotter on a longer ride...... It does smoke A LOT and its obnoxiously loud ..it kinda sounds like a mini Harley ....so i made a new chain tensioner and for some reason its slipping off ...and i don't know why all 3 sprockets are in line ill have to take a few pics tomorrow for you guys the batteries are dead in the camera and i have to take a dump so fist things first so ill talk to you guys later .....Oh god its starting to crown!

DUDE..... gotta slow your roll...... TMI.....

Now back to our regularly scheduled progam

I love the smoke aswell. That is so cool.. I see the bike is much bigger than I thought. How the torque for sitting straight on the seat. Look like it could throw you off if you gaver.

short video

here is a short video for you guys i was only half throttle............ Ok never mind it say's invalid file when i tried to upload it.... so it looks like im gonna have to post it somewhere else then give you guys the video link...ill do that real quick and ill be right back

the chain keeps popping off for some reason..... everything is in line and seems to perfect
so i don't really know what could be wrong... Any advice would be very helpful
i don't have a camera right at this moment or i would have posted a few pics for you guys to inspect and comment on

 

[souperman000]

didnt you have a chain tensioner on it earlier?

 

[numscul]

Yeah i did have a chain tensioner on ....... Do you think that's what it is?....You think it might be too tight ? Or too loose ?..........I almost BIFT it right in the middle of the road ...it seems like when i hit around 30mph the clutch kicks in and i get a 10lb boost Then it starts speeding up a lot faster................ I don't think i wanna go any faster thinking the chain might fall off again and get wrapped around the rear axle and flinging me off like a 225 pound rag doll... And Every time that happens the same thought goes through my head .."How many teeth am i gonna loose this time"

You have a gear ratio of 3.57:1. That is extremely high, and probably the reason why you have such poor acceleration and torque. If you get a larger rear sprocket (or smaller toothed clutch) you will find that your take-off will improve a lot. You might destroy your clutch as it is at the moment

 

[numscul]

SOOOO that means ?? it will take off faster.... but!.... wont go as fast in the long run ...right ?

Correct. You will also be saving on buying clutches.

 

[numscul]

Lets just sat i have an unlimited budget....it there a way for me to have the best of both worlds and still have it be reliable ?or better yet what would you do about it if i was having you build it for me with an unlimited budget im already about a $1000 bucks into this project ....i might as well go all the way

 

[Bluethunder3320]

the way you have it you could get a HIGER top speed by giving it slower gearing. think of it like trying to drive a manual car from a stand still in 5th gear. that clutch is working its arse off

diesels do have a lot more torque than gas motors, so that helps, but i bet if you were using a gas motor the bike wouldnt even move

 

[landuse]

Blue is correct. If you gear it down a bit, your bike might actually reach higher speeds because it is not having to work so hard to get there. It could be one of the rare cases where this could occur.

Unfortunately though, there is always a trade-off between torque and speed. The more torque you gear for, the lower the speed

Well i think my mom will be happy with it just the way it is i don't think she will want to pop a wheelies or go mud bogging with it she's almost 55 years old ....It will most likely just sit in her barn until its mine again.... I'm going to post pics of the finished product this weekend for you guys .....And i just want to say it again ....You guys were so much help and i want to say... Thanx again for all the thoughts,ideas and input on this project
OVER & OUT !

So have you given this to your mom?

No problem with all the help. It is cool seeing a project come together and actually get finished for once.

no i haven't given it to her yet ....my mom lives about 4hrs north from my house in the bay area......my friend is coming over today with the camera ......i never start a project and not finish it ...even if it's a total disaster
so i made a chain guard for it and did a few other things to it since the last time i took pics ill post a few more pics for you guys a little later

My mini bike does the same sort of start as you described. Only thing, my minibike has a 48cc engine and tops out (theoretically) at 28 mph.
