DNA is a 4 stroke so not that tuneable. What kind of runner 180 are you talking about? There are 4 and 2 stroke versions available.

Malossi makes a 210cc 4-stroke kit that, with performance parts, can push out something like 20-22 horsepower with a top speed around 90-95mph. I rode a friend's once and it was the most powerful bike I'd ridden, plus it had a PM Tuning exhaust and sounded f*cking lovely Smile

.

As for stock, the 180 Runner can reach around 85 mph and hits 60 mph from a standstill in under 6 seconds. The added horsepower of the 210 is more for acceleration as the scooter and rider combined are hardly aerodynamic Smile

.

It seems to me that DNAs, while sharing a lot of parts (engine as well, I think) with Runners, aren't as quick.

Anyhow, here's a link to the PM Tuning website that lists the available upgrades for each scooter.

EDIT: Changed a bunch of numbers, as they didn't seem quite right Smile

The 210 is suprisingly slow, there was one at santa pod that ran a 19 second quarter. The two stroke 180's could do that pretty much bog standard. Its a quite bit less than 30hp from the 210 kit. The DNAs are quite heavy which makes them a touch slower than the runners.
VXR 200's are a claimed 21hp at the crank, so just short of 20 at the wheel. Runner 180 two strokes are 17hp. Both are pretty much similar in top speed, but the 2 stroke will accelerate faster. Both will probably get to about 85-90 on the clock speed, so are a bit slower in real speed.

I was really into Runners for awhile when I was borrowing a friend's so I have a bunch of numbers, some true, some obviously BS, floating around in my head Smile

. I've seen a lot of people claim 28-30 hp from their setups, though I have a feeling those were the 2-strokes. Sat there staring at my post trying to figure out if I was spreading lies!

Anyhow, the 210cc kit with performance variator, exhaust, carburator, etc, should be able to push out horsepower in the low to mid 20's. If a Roadwin 125 with just an exhaust and 175cc kit can make 19 hp at the crank, I don't see how a better tuned 210, more specifically a Malossi, can't get a little more!

And yes, scooter speedos are often innacurate at higher speeds, so it's hard to tell if the speeds someone lists have been adjusted to compensate - quite often they're wrong Wink

.

EDIT: Ok, I confused the 210cc 2-stroke and 4-stroke blocks. I remember reading this exact page about a year ago and crossed it with the 210cc 4-stroke block from Malossi. Sorry about that! Razz

No problem Ben. Very Happy

Actually the 172 is a bit pointless on a stock 180 as there is only 1/2 a hp advantage. Better to put a bigger carb on a 180 than 172 it. A 172 on a 125 is only going to beat a 180 off the line, 125 gearing is to short to be able to beat a 180 for top end.

yeh. It is pointless 172-ing a 180 engine. But a 125 with a 172 mhr cylinder on would do a 180 off the line...

Im really disapointed with my speedfight...
Since I got it rebuilt, its been slower, way more sluggish, Shit up hill. and basically crap...
I can only *just* keep up with the derestricted 50ccs with race pipes...

Is this because ive got an Airsal cylinder on it?

Yeah, they aren't great. I don't know why PM sell them. Get another MHR rep one to replace it with.

Bens post has a few typos, but the 172 is a better cylinder then the 180 as it has a different bore and stroke and has better porting. Its also more tuneable than the 180. Just to confuse things there are 125/180/150/172/185/190/210 cylinders avalible for the 2 stroke runners and dragsters. Very Happy

and the 210 is the best...

(Sorry Mchaggis, I was tired. Ive corrected the numbers now tho Embarassed

)

But yer, Its similar to a 70cc mhr cylinder Vs a Speedfight 100cc cylinder. The 70 has a better bore etc and is much more tunable...

but yer, I was tired and got the 2 and 0 the wrong way around!

I wouldnt mind a dragster. But Id rather ahve the 50cc plastics on the 125 because the 50s have a single seat unit! Wink

Well they're not going to say a cylinder they are selling is crap are they? Rolling Eyes

Ben: you can fit a dragster 50 pilion seat unit to a 125/180. The 210 is not the best as it is expensive and all the fastest dragsters run 172's. Although I have yet to see anyone try one of the 210 kits.

Shame your stuck with the poxy Airsal cylinder, I would save some cash for a better one if you plan on keeping the bike.

Well im keeping the bike for summer and commutuing short distances. It is only £90 a year for me to insure... Mr. Green

All the money I have got now is going towards my mini and driving lessons...
I can change the piston ring in 20mins so if I change it every sort of 1000km then I think it should be ok for aslong as I own it...

Im gona get away from the scooters Wink

I want to keep my scooter for about 5 years (yes, i know its along time) But im going to insure it each year for the sake for what it costs. And then in about 5 years time I should have 5 years No claims plus a clean bike licence to put towards a Big bike Laughing

Should help my insurance a fair bit...
And I can then use the scooter when ever I want as I can ride it on my car licence...

I would say every 5-6 months, to be honest. I'm guessing your speedfight isn't under any particular strain, like from running a hotter spark and a variator that sticks you at 12,000 rpm all the time, for example! My RX-100 gets its rings replaced every 4-5 months and I have it past redline quite often Embarassed

.

Regarding the Airsal, my mate had one on his GPR50 and once the carburator was tuned at the shop, it was quite fast. I raced an MZ RT125 against it and was beaten in a straight line from 0-72 mph. He was able to reach 78-80 mph with it. But, the quality seems to differ between blocks. They're really the budget kits, and he was lucky enough to get one that was good.

Well, Mine isnt actually that bad. Its not actually much slower than it was before. Its more the fact that my scoot hsa got torque drivers on it and is geared the opposite way so its got more bottom end. This caused the bike to rev fukin high and only do 50-55mph..

<|Binge|>

Ive dun nearly 400 miles on it since the rebuild so its virtually run in now. Ill give it another couple of hundred miles then ill take the cylinder off and take a look...

How do I bleed the fluid in/out of the cooling system...

Cheers...
