Oh really? Why do you say that then? Sounds interesting !

The correct word is tire rollout changes. With reduced tire diameter, tire rollout is also reduced and top speed is reduced as well.

Cool. Looks like you got the new one. When did you get your kit?

Are you referring to running the external filter with the 705 tank or the 710 tank?

The 710 tank (with the bronze filter) never needs the external filter to run properly.

If you look at Julius' and Michael's 705, they have the small Tornado filter on it.

I also thought I saw the small external filter also on Michael's 710 in Thailand.

With the updated tank with the bronze filter that is supposedly coming with the 710, you can reduce the tank volume by using inserts.

I have the same tank as JustRace.
Our tanks have the hole for for decreasing the volume.
But, we have the old white filter.
I guess we got the in between model.
We have the new tank with the old filter.

Always try to run the same tires front and rear to maintain the equal front and rear overdrive.

Using larger front tires will give you overdrive i.e. front pulling the rear. Using larger rear tires will give you underdrive i.e. rear pushing the front. This assuming the internal pulleys are the same as the ones in the kit.

What I do is I maintain a few sets of tires. I use the rear tires and when I find that it goes slightly smaller than the front (about 2 or 3 mm difference), I swap them for another that is about the same diameter as the front. Of course this is for the weekend runs. Front and rear tires will wear but at a different rate where the rear is faster wearing than the front.

As a rule of thumb, I use about 2 sets of rear tires (intermittently swapped) with 1 set of fronts.

I run my tires down to about 55 mm but like what R12 mentioned, you need to change your gearing accordingly to compensate for the reduction in tire rollout due to smaller tire diameters.

Strange... I guess you still need the external filter going from what you have since the bronze filter is the one that makes most of the difference. The ability to change the tank volume is nice only when you race in big open races.

Take a look at the all new GQ truers at www.daltonshop.com for descriptions. It will start shipping early march.. Automatic with edge sanders + 1/10 and 1/8 wheel hub at average of USD250 worldwide

I guess so... On the first build, I actually missed that part about locking the pin with the H11 set screw. I used it after that and I found it to be cumbersome taking off and putting it on. So like Goldfinger, I don't use it too.

Like you, I also found some quirks when using the set screw but my experience was a little different. When I tighten the set screw, the white 2 speed shoes got stuck in the 2nd speed aluminum housing bell. This happened intermittently though...

No... Do like what Julius suggested. Loosen the 22T side left pulley on the 2 speed layshaft and fix the 2 speed housing with the P13 pin spaced snugly and the spurs able to rotate freely. The push the 22T pulley onto the 2 speed layshaft just enough and tighten the set screw onto the shaft to lock it in position.

Like what Goldfinger mentioned, mind the spacing of the pins from the brake pulley adapter from rubbing the right bulkhead. Also, spaced the 24T brake pulley so that it clears the foot of the engine crankcase where the engine is bolted onto the engine mount.


I think the way the 2 speed screws are mounted onto the white clutch shoes holding the springs, you need the holes to be slanted.

I have seen a friend of mine adjusting it from the external once or twice with the Hudy 2 mm allen driver but I never got to do it on mine successfully. Like you, I found the hole small. I prefer to take it out and asjust it. That way, I can see really how much is adjusted.

The trick is to get the angle correct...it takes a bit of shoving and twisting but eventually you'll get it in...it can be a little brutal though..

Oh yes, this "friend" of mine just turned up from no where !

Yeah. It's a hit or miss if you insert the 2 mm driver through the holes in terms of how much is adjusted. I find that the springs in the 710 is pretty sensitive unlike on the older 705. That's why I take the whole thing out and adjust it as I'm not soo brutal as you are !

It will make it's debut this weekend w/ a hand modded Palmaris NS12 Novarossi ....

thanks for the correct word, atleast i was in the correct idea
