:smile: I've had a good chuckle with the replies,

The cost to enter the Mopedathon is $30 per team of two or more, as to whether there are any winnings; it's solely bragging rights. All money goes to charity. In regards to Wheelman and Taz's comments on pit stops, refuels have to be carried out with the motor off whereas with rider changes, only the scooter has to be stationary. As for heat it'll be a sweltering 18 degrees Celsius (64 Fahrenheit) :P so not too bad, apart from the slightest of slopes for drainage, the tarmacs flat as a pancake.

Wheelman - I presume you mean't something along the lines of your thread:

http://www.hondaspree.net/phpBB3/viewto ... rease+fuel

It's definitely going to be on the to-do list...

New pulleys from Taz will be on order as soon as my finances are in order :woot:

As for sponsorship, I'm open to the idea....

Greetings:

Well the oil tank's additional quart's capacity increases the Spree's capacity by almost 50 percent. Still, three fourths of a gallon won't get you all that far into the 6 hour event. If it were legal, I'd strap a 5-gallon can to the luggage rack and splice it in. Sprees are slow; stopping is slower. :wink:

1st, hit up ebay for an express tank the the square style it holds a gallon of gas bolt on to rear rack.... (still need to figure out how to get more gas)

2nd, I dont know what your budget is but you might want to consider a motor swap for a var. motor (dio, af16, or afo5) that you can put bigger gears in to have i higher top speed......

3rd, Good Luck lol

Ooo, interesting race.

That Nifty 50 is a fixed ratio, right? No variator, in other words.

First, get all the fundamentals solid, as that first list said. And get some good tires on it.

If you know how to port, or know someone that does, I'd do that first. If not, just clean it up good.

Second, I'd build an expansion pipe for that thing. The one I built was perfect for 15-35MPH transitions... where it fell down was going from 0-15MPH. Built from a pocket bike pipe. I always thought it would be the perfect pipe for a race bike, since it really helped it pick up speed more quickly, but was pretty poor for launch... which you only do once if you're riding right.

Image

Bucket bikes... funny. They don't even sell bikes like that in the States anymore, even as donors. You'd have to run 50-150cc stepthrough Chinese bikes if you wanted a class like that. Bikes in that size are all antiques here and somewhat valuable.

Have fun and let us know how it goes.

Hero Honda. There are a whole line of 100-150cc bikes sold in India, under license with Honda and built in and for the India market.

Smaller size bikes are those Loncin "pit bike motor 110cc" motors. 100cc, 150 MPG. Start at less than INR40,000 (about USD$900). One model is even fuel injected (!!!) Not available in the States though.

I've asked the organisers and unfortunately we can't "add" fuel tanks to the bike, be it in the form of tanks strapped to the panniers or foot well, or carrying fuel on the rider (someone once filled a cheap Camelbak up with fuel to give them another few litres).

Sadly, my budget isn't that big to consider doing a engine swap. At the moment, it's looking like I'll just be doing the porting, Oil tank conversion, pulley change and possibly making a expansion chamber.

As for the bucket racers, they're definitely vintage, we don't see too many small engine road bikes over here and haven't since the '90s. Whether they are valuable or not is a different story :lol:

Sorry about the delay - I've got all the fundamentals sorted and have just been riding around enjoying the wee scoot. I had put off doing any of the mods and keeping it factory; as I was feeling rather * :jack: as one of my co-riders offered his Aprilia RS50 to race - capable of over 60mph in race trim with large disc brakes and a 13L fuel tank.

Things were looking good. :woot:

http://pictures.topspeed.com/IMG/crop/2 ... 460x0w.jpg

Until he overheated it and K.O. the big end. :shock:

Now less then a week out from the race and the 'ol Nifty 50 is still in stock form :lol:

The other competitors are riding everything from little water-cooled motocross pit bikes with slicks:

to Suzuki A50's; they're 3-speed with a speedo that reads to 60mph but I'm not completely convinced:

and finally to the ever faithful Dio.


Needless to say - I think we've got this one in the bag :eyeroll: :nervous:

G'day All

It's going to be a big update - I'm happy to say our team won the Step-Thru class, but it wasn't a completely clean race.
Two punctures, two crashes and having to run back to the pit after one of the team ran out of fuel due to a faulty fuel gauge.

I'll start with the lineup from last to first place on the grid:

The organiser's bucket:

Image

Give it a Nudge Racing - they built there bike in 3 days out of odd bits and even without a battery or kickstart managed to do pretty well.
Note: Ratchet start - possible upgrade mod for when your starter fails?

Image

Image

And yes that entire toolbox was needed to keep theirs and other bikes running.

Next up, the lone 4-stroker. A 3-speed with a knackered gearbox leaving them with only 2nd and 3rd; not the fastest way to get around a twisty track. BTW, this was classified as a step-thru scooter.

Image

The following team had a water leak putting them out of the race at the 3 hour mark - however at the time, all the buckets were roughly within a lap or 2 of each other.

Image

Then it was us - our Blue Nifty serving as our dedicated racer and the red one borrowed from a mate as a parts frame.

Image

Next up, was a Chinese mini-moto with a massive CRF450 front brake setup on there little frame - it's surprising they didn't cartwheel down the runway.

Image

Image

The 'ol Dio, she wasn't anywhere near racing form - she definitiely needed a good tune up. But boy was she hard to miss in that striking colour scheme.

Image

The eventual winners were next up

Image

Brown Bullet Racing were next in the queue:

Image

Then there was the bmx, he was reasonably quick but had a few good falls too. He had to shoot off before the race finished unfortunately so we can only guess where he would have come overall:

Image

Then in first place on the grid was:

Image


That's the lineup sorted next up some pictures of the track taken from pit lane- I'm trying to get an aerial shot of the basic track and post sometime next week.

Image
Image
Image
Image
Image

This next shot is during the practice - note both size of the little Spree and the distance the far riders are out - the course length was about 1.1km(0.7mi).

Image

Our start wasn't the best - we were stuck on the line with only the electric start - 30 seconds later and we were away. The guys who were ratchet starting usually took 5 min to start so were allowed to start the race engine on.

Our clutch wasn't the best, in fact when I found out we were racing the Spree I decided to rip off the clutch drum to find a clutch that looked a lot like this:

Image

As you can imagine, it wasn't the best for pulling out of corners - or anything for that matter.

The guys on the moto bike had a recurrent problem of their swingarm nut falling off (twice) and the bolt half falling out. A puncture and a blown water pump ended their race around 2 hours in.

Image

They weren't the only ones with punctures - with four teams suffering a loss of air.

Twice (both times whilst I was riding) we had to stop for a tyre change - thank you attrition frame.

Image
Image

Pit Lane was walking speed - so with a worn out clutch it was quicker to canter through the pit lane both to save the clutch and escape the condescending eye from the clerk of the course for speeding.

Image

Next up is a series of photos of some of the team racing - note the Spree trying to overtake the Dio both around the outside and taking the inside line... and succeding!!!

Image
Image
Image
Image
Image
Image

Then one showing another team around the same corner:

Image

Then a few more of us:

Image
Image
Image

At the 5hr and 50min mark, Give it a Nudge Racing's makeshift scooter sheared an axle in half - loosing the rear wheel and providing a bit of drama in the closing stages of the race. He's filing the axle so he can cross-thread a nut onto the axle and finish the race.

Image

And then come the end of the race, the results:

We took out the trophy for the scooters, beating the geared bikes as well as the single speeds and came 5th overall. We lapped 172 times, 5 laps behind fourth and 15 laps behind third; with each lap taking approx. 1min 50 sec. So not too bad considering running out of fuel early on (the gauge works from full down to half - we couldn't understand how the scooter was running so well on so little fuel until...) two rear tyre pictures AND two crashes.

Image

And finally a close up of the BEAST and a little bit of tyre peeling - no chicken strips on our tyres.

Image
Image

The next mopedathon is on January 28th, 2012. Game On :thumbwink:
