tuning an rxs 100 help needed???????

[inov8]

Hi have an rxs 100 and want to do the look of it up.

Ive attached a pic of what i want to do to it.

Can any one reccomend a belly pan that would fit nicely with some modifications.

also reccomendations on a front and back mudguard, rear shocks & exhaust and help would be much appreciated

The little RXS is quite tunable as it has the same reed block and transfers as an rd 125 lc. I'd be tempted to fit a micron or big one pipe on it and jet it you should get an extra 10mph out of it and a bit nippier getting there..as for the styling..erm thats up to you

I think you've got the pictures the wrong way around, the first bike looks loads better!

Id much rather ride the second one, looks like a good bit of fun offroad.

Anyway back to the point, a universal MX front mudguard will fit, you just need to make a compression fitting to hold it into the bottom of the steering stem. basically, from the bottom up: bolt, mudguard, suitably sized pipe, nut. Tighten that up and the pipe will get compressed and expand sideways, this should lock it into the steering stem, also make use of any tapped holes on the bottom of the yoke to add other mount points though, you dont want that coming out any time soon.

rear shocks, just buy some stiffer longer ones with the same fitting, 14 inchers would suit.

rd125lc belly pan should fit on nicely with a bit of bracketing.

And heres a tip from ben over in america on how to make expansion chambers for 2ts.

thanks for that info, very much appreciated

Port it, do the squish, use a choke side carb off a 31K model RD350YPVS and fit a Micron pipe. Remove the end can and chop it down, also shorten the baffle to suit. Junk the airbox but do not fit a K&N, run an open carb or bellmouth. Remove the oilpump and run on a high quality 30:1 premix.

The above is what my mate did to an RXS and it went like stink. He was planning a 125 conversion untill it got nicked.

Is it possible to fit electic start to this?

[inov8]

has any 1 got any ideas for a rear mudgurad that would fit on nicely

[virus]

Dont bother fitting a new rear mudguard, just trim the old one down with an angle grinder, cut off any unimportant bits, like the plastic below the numberplate etc.


Cheers
John

stinkwheel Well I just had my hands up a pigs fanny. Which makes your concerns pale into insignificance.

[inov8]

just had a quick mess about merging the bikes to get an idea what it would look like with a standard exhaust

out come

[inov8]

what do you reckon a kx60 mudgaurd would look and fit like? any one

[bladerunner]

I'd say the pipe is the first thing you want to change as it will be the bit that gives the best performance gain!! Fitting a front mudguard like that will just give you a face full of water every time it rains but hey I guess it's your bike so your choice!!

If you want silly power then BDKracing do a 190cc big bore for them with a matching pipe....as well as a tuned pipe for the std 100cc top end..but it wont be cheap but hey scaring them aprillia 125's and cagiva mitos on an RXS100 has always got to be a giggle!!

The tuning I described will shorten the piston life but jetted properly shouldn't explode every five minutes.

Can anyone reccomend any where to get a pair of 14inch shocks with same fitting, can't find any on ebay. thanks in advance

[bladerunner]

as a matter of interest have you measured the length of your standard shocks first?Tthat is hole center to hole center by the was. Also you'll want to match the spring rates for the size bike. No point putting shocks on with springs for a 750 four on the little RXS

Get a set of shocks from a MZ250, they have 2 settings, are 14 inches, and cheap, perfect for jacking up little bikes.


Cheers

Not had chance t measure them yet, as its at my mates garage being rebored at the moment, Hopefully should be done on monday for me to pick up, Il measure them then. I just want larger shocks to jack the bikes back end up (for looks)

I dont want to paint the tank and side panels as there in excellent condition. I've been trying to think of a colour to paint the mudguards and bellypan, so far i think white will go with it, any one else have a better sugestion, can't wait to get this done, hopefully found an rd125lc belly pan
