Its like a 450 bike running supercross and they only get up to 2nd gear. With a 6000kv on that track I doubt you will ever see all that speed used. Its overkill. You put in something like a 4500 or 4800 and you will use more of the power where it matters. You should read the old thread from the guys discussing the Schumacher M5 Anderson race on that grass track over there. I think the guy on the fastest orange bike mentioned his high kv motor was overkill.

Btw, I looked into that dxr slipper for my dx450. When I looked at pictures of the dxr race bike, the shaft used looked like it was designed differently, maybe shorter or the inner shaft grooves for e-clips didnt look right. I wanted to do it, but I passed. I will be curious what you find out if you do the mod.

Oh, and whilst we are on track performance, I'm ditching the roller wheelie bar before this weekend. They may be great for pulling long wheelies but when you just want to get the power down and distanced covered... It also helped the bike roll over easier 'can't explain to a conclusory satisfaction.' but the wheel bar induced the bike to sit up and carry on it's pirouettes. The drag bar caught hold of stuff and slowed the bike, getting the front end down again. I shan't test the wheelie bar concept any further. They (Wheeled bars) seem a hindrance to good performance.

Summary. Roller wheelie bars are useless.[/QUOTE]

If you are interested I have the details of someone in UK who has made a mould of the body and mudgard where he is able to produce a GRP body set with a layer of kevlar mat bonded into the tail mudguard section .
I have tried one where you can actually pick up the entire bike by the tail section with no sign of flexing so should be able handle the odd wheelie no problem
He can colour the gel coat in any of the standard Anderson colours
Slightly heaver than original but feels more robust

Does anyone have a picture of that?

Maybe it's overkill, but now you mentioned it, that and the Alpen cup threads need re reading...
I'll order the DXR clutch regardless. You never know what can be brewed up.

Send me a pm. It's either that or I'm looking for piano wire to fix a 'drag' bar.

I'm considering something similar, but where the back end 'catches' (like old school metal scratchbars) and gets that front end down again. The 'wheelie easy on the roller bar' just does not cut it for a faster lap. It can also really cause problems when the m-gyro slows and of course that just leads to a bike trying to flip around like some late '70's NY streetdancer. It's no wonder the buggy crew think my bike is crazy! (They just don't know really, I pity them having to cope with the stability of 4 wheels all too predictable. Jajaja!)

The motor I'm still considering. If you are good with the thumbs...
I'll see what I can get fabricated from the DXR slipper. There is also the radio to play with, all the fancy throttle curves etc.

I've never had so much fun with ALL my clothes on! (DO NOT ASK about anything else!)

Just noticed the new MOTO tire for... 1/8 buggies:



More details here: http://www.raceaka.com/18-BUGGY-MOTO...RTS_p_679.html

I think it will be a perfect fit for the Anderson/DX450!!!!

Does the width of the tyre matter? I guess there's clearance either side of it to consider too, but does the thickness of the hub it was intended to fit on have to be the same as the M5 wheel? Buggy tyres that I've seen looked a lot wider.

Interesting tyre Steliosh, I'm currently looking for a good off road rear tyre, so far I've only tried the standard one and the Pro-Line Badlands, which was my favorite.

Any other suggestions chaps ?

I have successfully used a 1/8 buggy tire wrapped around a "bald" M5 rear tire... I just had to shave the left side a bit, so it would not mess with the chain...



Just spot-glue it with CA at 5-6 points on the old tire, around the circumference...

I do NOT know if it s good for the bike, but it certainly looks more like a Moto tire than a buggy one!!!!!!!!

Yep, same way I did the Badlands, cheers for the pic

Anyhow, after numerous front end hits a lot of play has developed in the headstock plates causing tank slappers (even with a damper) so after a rumage I found some suitable flanged bearings and the modding/butchering has commenced.

The plate on the right has been drilled (using the step drill pictured) so the bearing sits flush and is a nice tight fit.



Bearings fitted using threadlock.



More to follow.

Will do tommorow

All fitted and it feels very nice, smooth and with minimal play and if the bearings fail too quickly then flanged brass bushings can be used.

I see. Thanks. I assumed it had to be fitted to the rim of the bike wheel.

You'll have changed up a gear by making the wheels a bigger diameter. I don't suppose that matters much though. You could always change the pinion as well.


That's a neat bit of engineering, Bonzodog690.
