Ground Clearance!
Running a RG150 Rear shock now - No more scrapes on the expansion chamber.

I have a semi motard for the next race as well . KDX200 With adventure tyres. - Yeah!

That frame is cool!!!

ZZR. Heavy like a ZXR.

[quallman1234]

She is a fair bit heavy

I could easily get rid of 2-3kg by cutting the subframe off. but then i would have to make a mount to fit the seat and i cant be arsed.

Thats the RS50 Aprilia Chassis.

Mate, honestly you don't need to do anything with that chassis, I rode that thing before Ivan got his mits on it and it was one of the sweetest handing little things I've ever ridden (with the original motor)
Just keep developing it Quallman you've got a good start there

[quallman1234]

No plan too take out the subframe it will make it too weak in a crash and rip the seat to piece's even in a little crash.

Next plan is to play around with the forks.

What did you do to them ivan? You mentioned putting valve springs in to stiffen em up.

They are currently far to hard. Only has about 30mm of travel. Wanting about 130mm. Glen suggested take the valve springs out and playing round with fork oil weights with the normal springs. The dampering rods seem to be really long!

Apart from the Front and Rear suspsension and the expansion pipe anyone got any suggestions on what i can do or should i just race the thing and see what breaks!

When's bayden putting up the calender im getting inpatient!

Gotta make a flange and weld it on to the end of the pipe tommorow at work.

Is that a VFR400 s/s swingarm you have there ? ...oops just read RS-50 chassis

So, when you guys are done teasing us civilians with the foters, when does the actual bucket racing start again? I checked out the KB and SCS calendars, couldn't see anything.

Bayden (who runs it) is putting the calender up within a week i guess?/ i hope.

Should be mid/late feb i believe (hopefully eariler!)

Hopefully not too early, I still gotta get my 'phones sorted so I don't blow everybodies eardrums into Karori!
But not too away either

I remember telling Ivan here that Valve springs were a stoopid idea. All they are is adding mondo preload, but the amusing effect of adding more coils means you are actually reducing the spring rate (although it won't feel like that if the preload is so high it won't move by pumping). DeIvanise it asap. If you need stiffer springs then seal with that.

[Ivan]

Yeah undoe them bolts on triple clamps and also raise thetriple clamps its dropped 60mm? i think...

we evenly lowered it...

yeah them valve springs are on top of the forks I did it for when I had the four stroke engine in there, When I rode it it was way to spongy and I put the valve springs in to stiffen it up a bit as the Xl was taking a bit of travel from just sitting there.

I agree with Sully as well thats a good base frame I rode it witha broken collar bone one day it was awsome fun handles really really well

Its a shame the bike got sperated as when dad sold it to Hamish hamish only wanted engine so Hamish sold the chassis to Nathan who chooped the frame to put a MB100 engine it..

Then I got it from Nathan and didnt chop a thing I justwelded them XL engine mounts in..

Then Welded some more mounts in when I put the AX in as I sold the XL125 for a 21 pack of Ranfurly lol

The main thing was playing with that jetting before that she was shocking....
I reckon if your gonna change the chamber id rejet the carb again as well

Doh! Thinking of the wrong bike... Teach me to look at the picture next time.

Your thinking of sully's ZZR frame. What he got from ivan for the MB ROLLING chassis.

Im going to guess but RG150 Springs wont be any good will they?

Too long probably. I Didn't even think about the postion of the forks in the triple clamps. Ill raise em and see how they feel. It did feel like it wanted to dip in too fast at the last meeting... So that should improve that hopefully.

So lets start at the start. They are RS50 forks yeah? & have RS springs yeah?

OK so the engine will be how much heavier than std I wonder? Take the valve springs out. Check static sag & race sag (search on internet). This should start to tell you if you need stiffer springs. Ideally you then measure what you have. Add preload as required to get sag right, but it never makes up for springs that are too soft.

Swapping springs has to be done with some care. I've shortened spring successfully (to stiffen the rate and then replaced the lost length with spacers) but you need some care to get them both the same, both flat & not coil binding.
