Is it Bucket legal or not?

Not exactly as available or competitive as an FXR straight off the blocks in any class I would have thought. The XL100 engine I have in my F5 bike at the moment isn't all that nice an engine to ride, and is about thirty years old, tried finding a piston for one lately? Only ones out there seem to be NOS genuine parts, on eBay from somewhere in Asia.

I think E.S.E have a few in the back of the shed

Drum brakes on both, not even up to rg50 standards

If your after a bike that fits f5 rules, is less than a grand but has the brakes/engine/frame that will make a good bucket racer for your average guy wanting to race, what would you choose?

Maybe a good F5 bike costs more than a grand, I have an Aprilia RS50 wasnt much more than that, we use it for training 10yr olds.

Must have been a number of years ago that an XR was raced in enduro's. When did the PE & IT stop being produced? Early/Mid 80's.

CRF100 - are Kids/Fun (Im guessing an XR100 rebranded as you cant buy a new XR100)
CRF150F - are a Trail bike
CRF150R RB - is the MX bike.

The trail bike/fun/kids bikes are the air cooled motors, the RB is the liquid cooled bike.

my two cents:

CRF100 engine looks more like the SL/XL. (legal) its not a competition bike; its a kids play/toy...
CRF150F - Farm bike; barely a trail bike, just Honda hype; we use them at work (managements' replacement for XR200s) and I'd rather have a 20 year old mudbug or XR200s back any day... there is no way these are a competition bike, it would be unsafe to try...(legal)
CRF150RB - pretend MX bike; honda's attempt to replace their CR80s.....Fail..... (but illegal).

But the classes are for miniature road race bikes not motards/trail bikes. for years people have been stripping engines out of "farm bikes"/road bikes or what ever and building road race bikes.
if you want to have a go racing motards get the motard boys to organise an entry level class (or if you are lucky enough the bucket boys might help you out); if you want to race F4/F5 put the motor in a frame that represents the foundation of what the class was originally designed around; Road racing GP bikes (I'll leave it to you about what generation/era of GP bikes you aim for).

F5 is a little bit of an issue regarding supply; the CRF100 fits the rules just put it in something...
(maybe someone should look importing in AM6 motors (10hp max 6 speed ~400USD out of china new or ~800USD second hand via Europe from China)).

"unicam" . . . . .

How to make a single overhead cam a selling point.

My old CB360 was a unicam model as was my CB750. I've owned cars that were unicam.

My bucket is "camless" which must make it pretty damn cool if only having one cam is something special, 'cause it's got one less cam than a unicam.

My car has a "bicam" engine. I knew it wasn't any good.

RG50 everytime. May be a bit long in the tooth now but a properly sorted one will still deliver a lot of fun and be relatively (to the amount of $'s spent to buy) competitive.

Now please point me at the F5 equivalent of an FXR, and it isn't an RG50, they seem as rare as hens teeth these days, if they weren't I'd have two by now.

Not sure mate. Maybe an aircooled 124 2 stroke with a 15mm carb
As someone said in a recient post maybe F5 is a dying class (hope not) and unless a saviour and within the rules bike comes along (as in an F4 equivalent FXR)...
With the current large numbers in buckets and the small F5 interest would it be possible to look at revamping the classes into say A, B, and C grade all based on lap times and results? Just a thought.

I think you can blame scooter's for the problem. I used to ride a GT50 to school there were guys on MB's and RD's all over the place. Little bit of street racing might have happened. Also used to sneak into Bay Park for a few laps. Scooters have taken there place. Sad but looks like not that many people are keen on them now. I love them. Will never build one coz I don't have the time.

I was only pointing out options for engines I believe two of the three honda's above are possible engines for F4 & F5, not the actual bikes themselves. I have ridden a DRZ125 around a kart track, and it is a hell of alot fun.

Well it was, back in the day, hence I had two (one for going to work & doing silly stuff like the Cold Kiwi etc).

In wgtn we have run A B & C for some years. We used to have 50 class, but sort of dried up, we need more & we could run the 50s off the back of the B grade races. Andrew Adlam has one but needs to get some wheels sorted so it runs proper tyres. Fishe still has one. We could get out & have a good race. Best races I've had have been on 50s.

Most of us are familar with the rules, for those that aren't,

http://www.mnz.co.nz/download/2012_M..._Miniature.pdf
MNZ have been/are of NO use to detirmine what is legal or not.
Lets collectivly sort this out!
We (the racers) are the ones policing the rules so we all should make it clear.
F5 is a great class just lacking no.s!!
There are very few donor engines available and those that are, are getting old and hard to find.
eg, RG50, Cb100, sl100 ect.
The only engine at the moment becoming very available is the XR100 or CRF100. but fall into the usual grey area.
My opinion is they are legal!!
What do you all think?
Also opinions on the CRF150f (2 valve aircooled, very similar to GL145)as legal or not.
Not the CRF150r which is the watercooled 4 valve motocross bike, that is clearly ILLEGAL.
Dont forget to vote on the poll.

If you turned out at one of my meetings on a CRF150F or an XR100/CRF100 (or with said engine in another frame) I would consider it fully legal for the classes they fall into. If a rider was to protest it they could put their $50 (or whatever) in the hands of the Steward at a meeting and find.... I am in no doubt..... that they would lose their money in accordance with the rules in the MNZ handbook.

Chances are JC and Skunk would be of the same opinion as myself.

Then hopefully that will happen and thus resolve these issues either way.

I'll have an XR100 powered bucket at the next Auckland meeting. Bring you fifty bucks, not sure but you may have to be an entered rider to protest so you might want to hav a troll through the rule book first.
