The Mut

I have been working on turning the surplus racebike siting around the olds into a bucket. ( "before" photo of it in my profile)

It has an MC18 NSR250 frame.
After 3 attempts at making wheel spacers I have one good one for the front to the left of the front wheel, that will allow me to put rg150 wheels on it.
crazy (and good) thing is that the left/right position of the rg disk and the NSR brake caliper line up EXACTLY right!

That means all I need to do is try get a flat brake disk cut to match the NSR pattern friction surface and the RG150 bolt pattern. That should save having to make a intermediate extra brake bracket and I don't have a spare disk for the bucket so was going to have to get another anyway

The rear wheel will also be made to fit an RG150 wheel but I want ot wait untill I have the last main ingrediant: the engine before I do that part so I can make sure the sprokets line up all good and the like.

engine options are still open and I'm still not set, I could:

1) buy a loncin

2) Piss about with an old jap 4 stroke single that would lug the weight around okish (she's gunna be a porker!)

3)Piss baout with an old jap 2 smoker which means lots of tuning to get it reasonable but should have real high power potential once sorted

4) do the done thing and try find a CB125 engine...

5) Try a novel and tupid (but interesting..) topsecret (not really) plan involving a overcomplex motor that should give good power but be too heavy.

So far I need to look into option 5 a bit more but I'm swinging towards the loncin at the mo, mainly to get some practice and track time in. (fastest bucket in the world won't win me a race at the mo!)

Input?
suggestions?

anyone got an old superworked ready to go motor and a winning lotto ticket lying about....? - no but seriously has anyone got any potential motors for my overweight beast?

I will try post some pics in the next week or so if anyone is interested...

Pic is the "before" (before I even got my greasy mits on it!)

I say go for the Loncin.

Cheap to obtain and have good power for what they are.
They are brand-new so you don't have to worry about internals condition.

More and more people are going the LongChin way, soon they'll have their own racing class !!!

I may be able to help there. I guess the cost would be about $150 but I'd have to submit the plans first.

I was almost sold, but seeing fishies one battling to keep up at ruapuna (on the straights) has made me doubt them a wee bit but the riding experiance gained from a reliable(assuming it is!) new motor may offset that a bit.
At this point I don't have the mad as ninja riding skills to make up for a lack of power but that doesn't matter as much at the slipway so maybe loncin it will be.

Just really thinking out loud here a bit....

Come out on the 29th and take Lady P for a burn around the Slipway.
That way you can gain some experience with them.

I know they're not the most powerful bucket engine out there but they have a great spread of power.
Also, from what I've heard, Fishie's was more undergeared than underpowered at the BOB TT.

As Nudes says, I think Fishies problem was lack of gearing not power. Remember too that those FXR aren't all std. The Loncin is.

You also have all the "hot up" kits for the loncin's.

Me thinks you should be a rebel and do something orignal.

a loncin

chinese housewives need the overtime

Cheers, Im keen.
Mats four stroke (whatever it is) was really impressive, I couldn't ride it for long because the ergonomics where all wrong for me but it seems like the meaty tractor power would be good for learning and hauling a porky bucket around.

Yeah, he was hunting around for a 520 sprocket, so he has a chain on the heavy side too. definatley more potential.

The loncin is a good base to do some home hotup too as gettting it working right to start with should be eliminated, but then it would prob be best left or only mildly touched...

Houswives are probably too expensive, children are heaps cheaper and have nice small hands.

**nudemetalz** · 16th June 2008, 13:04

Yup I run a 428 chain and sprockets. Easy to get a wide range of size sprockets.

Lady P has a 30mm pumper carb but apart from that is stock.
I want to gain some more experience with setup and also my riding before I go looking for more power.

Sounds like smart thinking.
Was the pumper the optional carb from Newmanz?

**Trudes** · 16th June 2008, 15:18

Sounds good M. *waiting with eager anticipation*

**bungbung** · 16th June 2008, 15:19

30mm pumper carb from Newmanz is a copy of the Keihin used on a GL145. It's hardly an upgrade, just the other carbs he has are more like a downgrade...

Matt's bucket is powered by a XL125 motor, which is pretty similar but with a six speed box instead of 5.

Certainly is the one.
Seems to carburet well too when warm, just quite lean when cold and needing choke for a while.

Yeah, they're no powerhouse but work well though.

XL125 added to search list....
