Testing the kawasaki engine in a race car at Mettet

[@ryann5247]

it's apparent from all you videos that you're super knowledgeable about things concerning your hobby and I think it's great that you're willing to share that knowledge in an easily approachable but still informational way

[@D3Sshooter]

Thank you Ryann, sharing amongst friends and alike is how we all learn and improve.. I have learned so much from comments

re the gear change. The return spring in the gear box is designed to centre a motor cycle 100gram 15cm gear leaver. In your car you will have a two long cables and a remote gear leaver to deal with. The remote leaver will need 2 centring springs. When working correctly, you pull back on an up change and let go, then pull again for the next up change. Lubricate the internals of the cables with ATF or light oil. Snip the corner out of a plastic bag, insert cable end, tape up so no leaks, fill bag with 200ml ATF and hang bag and cable somewhere it can drip overnight. Cables should offer little or no resistance when pushed or pulled. Replace cables if you cant achieve by oiling. When you get it right you will be able to do clutchless up and down changes with appropriate slight blip of the throttle. The clutch I would first try just replacing the frictions and steels with fresh OEM or std aftermarket plates and heavy duty springs. This won't cost much at all. Bikes fry clutches all the time and there are heaps of after market options.

[@D3Sshooter]

Thanks James. My car has no cables but solid rods and bars for shifting... But I will look into it....meanwhile I got a 20% stronger clutch and springs..

[@pdxRetired]

I would change out all the suspension joints that are the same type as the one that broke. They may have been stressed at some time in their past.

[@D3Sshooter]

Thank you , and indeed as I found out from the comments , these that are fitted are as it seems not for racing. They have been on it and looked good so , I kept them.Now we will change them

[@hughdanaher2758]

Started watching your channel for “Old Rusty” stayed for your other videos

[@davidneale5821]

Same here 😀

[@D3Sshooter]

Thank you , and in a few months I will be retired and have more time to continiue on Old Rusty

[@alanmcclorey8914]

Great video thank you

[@D3Sshooter]

Thank you

[@damianmulally2985]

I have loved your videos for years. Also something you might be interested in was that I welded a nut on the end of where my trailer winch handle goes and a cordless drill on the high torque setting does it easily. All the best for your retirement!

[@D3Sshooter]

Great tip!

[@roberthocking9138]

That was still good fun, it was a testing day after all and you did test it and found 2 issues . Now you have more fun fixing them 😁. Nice video thanks for updating us.

[@D3Sshooter]

Thanks Robert, indeed

[@54mgtf22]

Always interesting and entertaining. Thanks Steve 👍

[@D3Sshooter]

Glad you enjoyed it

Thank you

[@rotorblade9508]

high quality content as usually I don't think it's a weight problem because the engine delivers the same torque regardless of the weight unless it loses traction, of course with the bike max torque can be applied for shorter periods of time because of necessary throttle modulation and faster shift intervals. if the shifter operates like you described I wonder how would bikers use it? is it the gravity of the shift lever helping the mechanism settle down? you could add a small spring for that I guess

[@D3Sshooter]

Thanks for the comments, you are right as the torque of the engine itself has not changed. However the mass to propel is bigger ( race car versus bike weight), hence the clutsch plates are more loaded ... I have already found new clutch plates and stronger clutch springs with 15-20% increase in clutch coupling capacity.. So that should do the job..

[@salamander5703]

Great video and nice to see your analysis and development of the car. It would be interesting to look at the fracture surface on that joint. Looks like some fatigue cracking was there. Definitely worth checking the other joints on the car to see if they have started to crack too. Also, if you drove far with the joint broken, did it put extra stress on the other joints on that wishbone and links?

[@D3Sshooter]

Thanks for the comments, I decided to replace all the suspension rose joints, beter be safe then sorry

[@Mercmad]

My neighbour has a trailer of almost the same design . The tilt pump is something he needs 😅

[@D3Sshooter]

Yep that is handy.... this one came with the roof/top part . That is what I made

[@asciimation]

Interesting as always, thank you. Do you find people are a bit daft as spectators around the track and paddock? As in not looking out for cars. Whenever I have been at a track I am always super aware of cars moving around and staying out of the way but see so many people apparently oblivious!

[@D3Sshooter]

Yes, some people just wonder around and have no idea how dangerous it can be . That is why I prefer a closed pit/ paddock

[@noelobrien3570]

is there a vid of it in action with out commentary , want to hear how it pulls in gears . i have a similar car RF85 busa super..cheers

[@davidneale5821]

So will you be replacing all of the rose joints on the car?

[@D3Sshooter]

I will David, that is the best approach. Its about 24 pieces

[@davidneale5821]

@@D3Sshooter Expensive, but your life is worth more 😀

[@billcodey1430]

Glad you are safe. Did you just get a bad part or was it a part not good for racing? (trying to learn). Would be nice to know what you end up using.

[@D3Sshooter]

As it seems and based on good advice, those are not intended for racing.... but agricultural usage. They have been on the car and looked ok . I will get racing rosejoints...

[@oleran4569]

Can you use an impact wrench on your winch?

[@D3Sshooter]

Yes, that could work... thanks.... good tip

[@percarlsson792]

Sorry pal, but I long for an update on old rusty... not that interested in race cars... will it come or should I forget it?

[@D3Sshooter]

Soon, I am retired and will have all the time in the world to work on all the projects. Right now , have a full time job... so yes it is coming...

[@renoreno2701]

Doesn't the cantilevered screw that holds the ball joint create parasitic forces that caused the tail of the ball joint to break?

[@D3Sshooter]

possible, not sure

[@renoreno2701]

​@@D3Sshooter : Check if the bolt that holds the ball joint moves in its housing or not

[@rscruiser3533]

That is strange ----- the Heim Joint snapped in two ----- I'm like --pdxRetired below ---- I think I would change out -- ALL -- of those joints ----- it shouldn't have snapped that easy ----- that's what you use on hot rods ---- split the Wishbones and attach Rod end joints at the ends and bolt to the frame one on each frame rail ---- Boy ---- that would be scary if one of those broke ---- that's all that keeps the front axle in place ----- So yeah ---- change them all ----- get good quality ----------- Sounds like --- a Heavy Duty pressure plate --- heavy duty disc ---- resurface flywheel? may be needed ------ Your Racers look like a lot of fun ---- I really enjoy watching F1 Races ----- So Fast --- little time for a correction ------ Well --- You'll get her figured out and be back on the track soon ----- Hope you have a Good week ----- And have a Good Father's Day ------- Rodney

[@D3Sshooter]

Thanks Rodney, yes indeed all will be changed and the clutch replaced with a new set of heavy duty race plates

[@lewiswestfall2687]

F1000 (?) should be much faster than FF. More HP and wings with the same weight.

[@D3Sshooter]

Yes , it should however there a few things that make it not as good, especially in this case: Slipping clutch under fast acceleration, at high gears and at high RPM's -> Typical problem with a clutch that can't handle the torque. Second issue is the closer ratio of the gears, as it has 6 gears it requires more shifting, and shiftig takes time. The good thing is, that its sequential so that saves a bit of time. I am sure that if the issues are fixed , it will be faster...

[@vaporblast9721]

The man who buys everytool he needs doesn't have an electrical winch? Come one... compared to the rest they are not that expansive! 😊

[@D3Sshooter]

I need to do some power training every so often 😀😀

[@johnward798]

Rose joints with grease nipples are only fit for agricultural equipment

[@D3Sshooter]

Thank you John, That is what I was told as well in the paddock . TXS

[@rickden8362]

Was this car owned by a brit at one time, they like doing things on the cheap.

[@Sidney-Holiday]

Hi mate.. the broken rose joint.. hard to tell exactly what the geometry is like on the arm but looks as though that rose joint is in bending as the shank is not colinear with the arm and therefore the shank is not colinear with the forces?

[@D3Sshooter]

Thanks, It looked ok as far as I can tell. Meanwhile , I have the new parts and when they go in I will have a close check. thanks for the comments

[@Sidney-Holiday]

@@D3Sshooter No problem.. hope you get it sorted. It might be worth your while googling "rod end in bending".. it's a big no no in formula student yet is present on designs as unthinkable as the light car company's rocket. It's just so tempting to have as much adjustability as you can get on A arms. Your content is fantastic by the way and I'm learning so much from you so thank you for all the effort you put in.

[@D3Sshooter]

@@Sidney-Holiday Thank you and I will check on it as it is interesting . Are you a formula Student ? That is something I would not mind to do ...
