Dear friends, I am new at this forum.

I do have a initial doubt, what modern slick tyre sizes do you use? Now bike has a 180 rear but it rubbers the chain on its left side, any help? Mono arm has enough room to allow a widest tyre but the chain is a limitation.

Rear wheel nut torque?

Also I have a few spares I don't need so I think I am selling it:

Set of exhausts without silencers

If anybody is interested let me know an I will send to you some pics.

As soon as I can I will post some pictures of the bike.

Thanks

Welcome to the forum.
Please post the photos of your bike soon................We love photos..........The more, the better !

Hello "jotabe", and welcome to NSR-WORLD.

Great to have another 500 owner on board!

Is yours the "Repsol" recently advertised?

Any help with the rear tyre size?

Thanks

Nice purchase

The 500V should run a 170 section tyre. The DeeCee bikes run a 180 Pirelli Supercorsa street tyre, a tyre significantly better than slicks were back in 2000-2001, when they were raced! The DeeCee bikes however, run the Bakker frames and conventional swingarms, so clearance isn't an issue.

I seem to recall one of the tyre manufacturers (maybe Pirelli) does a 170 section street tyre now. Really, unless you're a pro, and really need them, slicks + an NSR500 are way over the top, even for the fastest guys I know... some of whom have won national (and international) level championships!

StephenRC45 will be able to confirm the tyre manufacturer when he's online later, aa I believe he'll be switching from 180 to 170 this year.

Just another point to note, even pushing out the power that the 2001 spec DeeCee bikes do, and having been thrashed more than a few times by some very competitive guys over the last 2 years, the Supercorsa tyres have barely a mark on them, and have worn incredibly evenly. There's no pratting about with tyre warmers, or worrying about temps dropping off if you don't push hard enough either. Many, who knew no better, criticised the decision to use street tyres, but no one who's ridden them has, and one bike's even done a few wet sessions on them with no ill effect!

Thanks for the help. Let's wait for Stephens opinion.

More questions, I've already read that best gas is ELF MITS42, and what about the oil to be mixed with gas? Also elf? Manual states a mixture proportion of 4%, isn't it too much greasy?

What are the options to buy parts? I've read here that members in USA an UK have stock.

Thanks again to you all.

I love this bike.

1.- Marvic 5 spoke magnesium rear wheel
2.- Marvic 5 spoke magnesium front wheel
3.- Set of exhausts without silencers
4.- Set of carbon front brake rotors never used, new.

Unless you have several sets of wheels and exhausts, I think you'd be mad to part with anything...

Lovely bike btw

The DeeCee's are set up to run on AVGAS, considerably easier and cheaper to obtain than MITS42. (About 1/3 of the price, I seem to recall.) They perform perfectly well on it.

We use Rockoil in everything! Street bikes, race bikes, and all the transmissions. The fuel/oil ratio is very oil rich at 25:1, compared to even an RS250, but they run fine and clean. My advice would be not to deviate from their mixture table, unless you are extremely confident to do so, and have at the very least spare pistons and barrels, just in case it all goes wrong!

2-stroke oil used in the DeeCee bikes is Rockoil Synthesis 2 Racing.

Thanks Andy.

Well, let's keep 4% then.

Didn't know the rockoil products but I'm gonna try it.

As far as avgas is concerned, could you be a bit more precise? Do they have a web site?

Thanks

Andy, which rockoil product do you use in the gearbox?

Isn't 25:1 equivalent to 2.5%? 4% would be 40:1 ?

Remember it's 25 parts petrol to 1 part oil.
4 x 25 to make 100%
4x 1 to make 4% oil ratio.
I presume I'm right?

Depending what the bike is set up for I would run avgas.

Of course you will need to check what PGM and fuel coupler is fitted as well as the cylinder heads. As on the RS's though the heads are easy to pop off and measure the squish and volumes.

There were 3 types of pistons and to run the leaded you really need the late piston with the semi key stone rings and domed head or the very early '97 piston with a standard ring.

We are running the 1999-01 pistons with the "C" heads with 23.6 and 23.8cc volumes (not including the plug). '99-00 PGM's with the a leaded coupler.

There are also different reeds and stops for unleaded and leaded set up so it's worth popping them out and seeing what you have fitted.

What fuel was the bike running on before?
