[quote=OSFlanker]Jules, any tips on driving the kart? Most of the corners which gear to use? Doesn’t the engine has a rev cut?
Can CityKarting start numbering/naming the corners? I know which one they can name “Fazlur Corner” – said with an ouch![/quote]
Agreed with OSF on tips for driving a shifter kart. Totally different animal.
And a corner named after me?? Ouch indeed!! *lol*
Tips on driving? Aiyah will tell u in detail when you test it-lah….both of u.
Fundamentally, U gotta remember the gears for each corners and all DOWN shifting done in the straightline ( while braking ) – a bit like a car on track.
For this kart, push to upshift, pull to downshift…..and no need overrev engine when upshift…
Rev limiter? your ears….so dun blow engine woahhh! No shift lite, or gear position okie – all those want to ask. ( norm for even the ICC world class karts )
Fazlur corner….aha, must be the one he spun at last race …LOL Ouch Ouch 🙂
er…..guys, I broke the gearbox of the Modenas kart! Had some trouble with the shifting for 1 laps, then when finally got the hang of it, the gearbox broke…….hope they will let me try again!

I don’t imagine that it would have been the most natural thing to do. Hey Jules sorry, could not try out the shifter kart on Saturday… but perhaps you can give some tips to avoid anybody from breaking the ‘box?
Mr OSFFlanker,
I logged in today in anticipation for your test report on the MiM shifter kart.. only to find out that you managed to ‘bust’ the gearbox.. anticlimax la.
Can’t wait until most of the kinks are ironed out to try it out.

for those who haven’t seen this modenas racing kart b4, i’m officially release this shortclips for my-kart.org

Great video clips and the shifting can be clearly heard…..Guys,
To be fair to the kart, I was TOLD that OSF used only 1st 2 gears when there were 6….over-revving for 2km would kill anything. Was not there in time to brief him unfortunately, so my error in some parts.The kart requires some minor sorting out but nothing major.
Whatever, it does require some technique to drive this properly and there’s no need to over-revving. ( pls hear the video ) Counting thru the gears while listening for the engine revs going up & down is a MUST. Otherwise, please look at TACHO!
OSF can verify that I suggested a REV limiter to prevent similar damage but this will add to cost. At that point, it was not well received. I proposed since one idea was to make these machines available for hire and will be open to over-revving mistakes/abuse. ( think of running 10 side by side…..at the start line & u get my drift… )
Blaming is easy then and it wun solve anything for the sake of the sport – hence the R&D now.
If the kart is to be made for rental, then it should be made more robust so that 1st timer like me won’t blow the gearbox/engine. It’s cheaper to install a rev limiter and rebuilding a kart every other week.

Jules / OSF – in what way was the idea for a rev limiter not well received? What would the additional cost be? Ultimately the question is whether the made in Shah Alam shifter kart is intended for re-sale (niche users) or for rental purposes. If the former, then of course the onus is on the owner to ensure no over-revving. But is the latter, I think it is prudent to install the limiter to avoid having to re-build every other time. What is the cost of the limiter and what is the cost of the re-build?
wwoooowwww…. it sounds like a real racer!!!!
love the part where u shifting up while taking the back straight.
and the part throttle at the hairpin, it sounded like it had traction control!! all that backfiring.hows the shifter positioned? i saw someone playing with the steering wheel, as though its paddle-shifted like an f1 steering.
lovely video. thanks “rookie”
Fazz, OSF,
I agree that a rev-limiter is best solution ( even if it’s for a private kart ownership ) but we will be on new ground here….at least for karts, it will be a 1st ( have not seen one in my Rotax…) and I am not aware if the car units can take the pounding, vibration, heat, water ( it’s exposed mah ) etc.
Am not aware of cost of such unit, so maybe some of you know. To re-built an engine is one thing…..maybe a few hundred bucks but it is timely as well, since running in is required after installation.
In short, I would push for a rev-limiter installation as then the market is unlimited……and MyKart can hire them! (without having to pay deposits for damages etc etc etc aiyah……)
Siewweng – it is a real racer, believe me & there’s a shift lever, clutch as well.

Would this not be a common feature for shifter karts? I know close to nothing about shifter karts, but there are shifter kart racing categories, and I am just wondering if rev-limiters are a standard feature. What about the Rotax RM1? How does it control over-revving? Or is the engine more robust to withstand abuse?
Doesn’t the RM1 has a shift light? Would installing a shift light a cheaper & simpler alternative to a rev limiter? But that also assume the driver will shift after seeing the shift light?
Jules, isn’t racing sequential gear pull backwards for upshift and forward for downshift? (it is on the BMW SMG 2)
Guys ( OSF & Fazz ), I appreciate the active discussion & contribution here.
Fazz, yes there is a class called ICC, and the one I drove before did not have a shirt light or rev-limiter. Brian E could also share his input cos he drove shifters in USA.
OSF, not sure-lah abt the shift light on the RM1…..can ask. But you are also very correct to say….if driver do not see it, it’s also pointless.
For this kart, you PUSH down to shift up…1 to 2, to 3, etc etc. The opposite for downshifting….ie. 6 to 5 to 4 etc etc.
I was also thinking about this, rev limiter cuts in when upshifting but does it cuts in if you downshift wrongly into the wrong gear? I doubt so rite? Car sifus, pls share.
We should sit down and give our comments in unison to Uncle cos as an individual, banyak susah……
Thanks again & yes OSF, you will drive again….with me around 1st! LOL! & for any newbies I will follow in the 100cc also as an added security. Okie?
Cheers!
