long time no post i havent realy done much in the spudding world heres what i have been working on last coble of weeks.


heres som picturs the frame is all but finished its just the boring bits i need to sort out now herer some piccys


















please post your thoughts etc

Wow that's quite some horsepower you've got there.

Are you sure the frame can handle the forces involved?
Keep us updated!

Looks like you may have to put a few cross bars in the front and some vertical supports as well. A small double rail along the sides may help.

Looks nice, though. I'm just concerned that the weight will fold your frame up when it gets to moving and vibrating.

no

its got a little flex but i wanted that my last one i made rock solids bit it was not easy on ur backside

And rather than a padded/cushioned seat you figured a weak frame was the best approach?

[maggotman]

i would not use the term weak if made it with some heavy walled box it may be stronger but it would not flex. my last one i madeto stiff and if you hit a small bump in the road at 60mph it would bounce and somtimes make you spin out.

the weakest part its from the front of the seat forwards behind all the rest has triangulation in it and is very strong. I worked out the new gear ratio should have a theretical top speed of 135 mph at 11000 revz in top gear i had a go on the bike before i pulled the engine out and it revs hapilay up to and past 12k so i think it will be down to the driver.

135 mph

I'd rather have a sturdy frame at that speed...

Just add padding to your seat.

No joke. That kind of speed is nothing to mess with, I would even make the frame way overkill if I was ever planning to go that fast.

My recent project has been a racing lawn mower, and I reinforced the frame quite a bit, and it's only gonna max out at around 40 mph.

[maggotman]

the reason the frame is minimal is to keep it light not purleay becuse of a better ride i would go as far to say it would be almost imposible to damage the frame thro hard driving unless you acutualy crash

Protection in between you or driver and the gear box would go a long way....That gear box set up will be screaming at 11000 rpm's. A roll cage would also go far for me. What make engine is that and why isn't there any air filters?

Stick a potato in the exhaust and enter it into the ghetto challenge

[Brian the brain]

Just as sick as your compressor experiments.
You seem to lack all common sense...No...fear..that's what you lack

It's fear that keeps us safe..not so in your case..
135 miles an hour means certain death could follow any small mishap...

Hitting something at that speed will certainly mean the end to your strange endeavors..

Please tell me you don't actually plan to try it?!?!?!
You and Charles Bronson man...pfff

[maggotman]

puting a role cage on it would make it more likeleay to flip. plus i would then need a full harness. you may think this is a good idear but if i did flipp it i would rather be thrown free. than straped in a mettal cage having no control. if i plann on going past 80 mph i intend on rering motorbike leathrs i always wear a helmet on it anyway anypart of the geer box will not spin any faster than its mean to. pluss its underneath the engine in the sump the engine is out of a yam.

shaft driven hence the engin mounted with the crank paralal tp the chasi.

i also plan on puting some mettal between me and the chain making a head rest

i also want a rev limiter to stop me over reving it and throwing a rod.

Make sure you calibrate your rev-limiter set point to 2000 RPM as a safety factor to prevent any injury in that death trap!

Multiple concerns warrant the above statement;

Flimsy frame? That frame is not made for much more than 5-10 HP.

Chain tensioner? Chain will stretch and fall off.

All wheel hydraulic disc brakes? You need to stop this thing at all speeds.

Rack and pinion steering? That steering setup is to narrow of range.

Engine cooling? Need fans and/or ducting.

You have to weak of a chassis and external drive train to handle that torque and engine horse power!

Been there, done that!

This is much more robust with only 450cc. Max speed 85 MPH.

lol are you trying to be featured in the faces of death or something like that??

I don't know much about go-karts but that just doesn't look safe
