Performance exhaust for the Rattler 110

[kellertattoo]

So I was thinking of buying the performance exhaust for my Rat but had a few Questions, Thanks in advance for any answers!
Is it gonna make a noticeable difference?
Will I have to adjust anything else to keep up with it or is it as easy as bolt on, bolt off? Should I just get the whole kit?

[laxer]

If you're talking about the Prima pipe, most everything I've heard tells me to say "save your money." It apparently just doesn't do a whole lot of anything different from the stock pipe, and isn't really made for the Rattler. If you can get your hands on a V8 pipe on the other hand, that may be well worth it.

no mod on a scoot is plug and play
if you just bolt a pipe on you wont get a darn thing out of it
you will need to at least check your jetting by doing afew plug chops
then you need to tune your trans to the new power band of the pipe
heavier clutch springs to let the engine rev into the power band before the clutch engages
lighter rollers to let the engine spin up to the new potential of the engine

. ... Should I just get the whole kit?

What/which kit?

[Keys]

I opened up the airbox at the same time I added the Prima pipe. Noticed a huge difference in low and mid-range power. Changed to 9.5 gram Dr. Pulley sliders and just love the thing. More power low and mid and returned my lost 5 m.p.h. top speed.

I think scooterworks has a stage one kit that has weights, some springs and the pipe. I can't remember what else it came with.

[kellertattoo]

Thanks for all the feedback, sounds like im gonna save my money for now. I dont want to get into taking apart to much without knowing what im doing. I was hoping for the easy way, but that sounds to good to be true,lol. It always is huh! Thanks guys!

I wonder how much of that you would have notcied anyway, all other things equal, absent the Prima pipe...

[Keys]

I actually did the airbox first and noticed a huge difference, but the pipe added serious bottom and mid-range poop. With just the airbox mod, it was an effort to lift the front wheel...it's easy now!

but the pipe added serious bottom and mid-range poop.

Wow, no wonder nobody wants these pipes...

[Wheelz]

MORE MID-RANGE POOP!

[Keys]

...I just hook a bag under the exhaust to keep the streets clean...

[nissanman]

Mid-range poop... what cha got up top?

[Keys]

I seemed to have lost about 5 m.p.h., but when I pulled the variator to put in the Dr. Pulley sliders, I also pulled and cleaned the clutch bell. Between the two, I regained my 5 m.p.h. Top speed is once again about 61.

the Prima pipe is made only for the rattler 110

if you look at what the 110 engine is it is a big bore 50cc meaning for more than doubling the cc's it uses the little 50cc 19mm carb, the engine is set up to make all its power below 7000 it is a high torque low RPM engine so unless you change the cylinder port timing enlarge the carb ( 24 to 30 mm) then add a shorter tuned pipe it will never be a high RPM screamer .

[B02S4]

...the engine is set up to make all its power below 7000 it is a high torque low RPM engine...

According to factory specs the stock Rat 106.2 makes max HP at 7000 RPM & max torque at 6500 RPM.

There is no reason in the world why a properly designed performance pipe would lose 5MPH off the top, as compared with stock, all other things equal.

My stock carb 106.2 with RRGS "V8" type pipe will exceed 7000 RPM & didn't lose top end.

I agree that the carb is a major weak link for top end power. It should have at least a 21mm stock.

Its not a big bore 50cc, actually. Its a long stroke 100cc Its the Minarelli 100cc with a stroker crank to make it 106cc. They then use the awesome power of rounding to make it 110cc

the 50cc is a close relative, but NOT the same motor.

[laxer]

So, has anyone changed out their carb for something bigger like a 21mm? Are there any that will easily swap with the stock carb?

[bikebuda]

this is why the pipe works best with 12 g rollers @ 6800 rpm

exceeding the factory red line by 10% shortens the engine life by 1/2

exceeding it by 20% "9600rpm" cuts the engine life 2/3 run it past

10000 and it will only last minutes

believe me this engine will self destruct if run at high RPMs

Don't you think the heavier contra spring that SW supplies with the kit has something to do with the supplied roller weights? (Laxer - you know the answer to that, right?)

Just what is the "factory red line"?

Where did you get those figures from?

[bigbropgo]

Pipe, big bore, Carb, weights, springs; I thought all this stuff helps achieve more out of a motor. (torque and maybe a little top end) but to get higher speed, higher rpm is the only way to achieve it.

[bikebuda]

i am not saying a pipe cant be designed to run at a higher rpm I am saying the prima is set for 6800 rpm ( to keep people from blowing up there engines ) as are the spring and rollers to hold it at that RPM yes you can go with a stiffer contra spring but there a different lengths to them also a spring acts very differently in the drive range with different preload settings a short stiff spring will initially keep it in a low drive ratio then taper off more steaply than a long stiff spring just as drive sheaths have different ramp angles cut into them

I deally you find the RPM that the engine developes its power at then adjust the trans ( rollers, spring, sheath) to hold the engine at that RPM this keeping the engine at maximum power trhis is how you get maximum performance out of it .

[Keys]

...but to get higher speed, higher rpm is the only way to achieve it.

Um, not exactly. All those things will increase torque and horsepower if done correctly, but the RPM limitations of the engine (bearings, races, etc.) will remain intact. The best way to increase the higher speed once you've increased the power and torque would be taller final gears. To the best of my knowledge, nobody's found the right ones yet...

I wish gears were easy to find. a couple of people have said scooterworld Guam has them. Dunno.

If it helps any, your motor is a clone of a Minarelli 1E50QMF, so gears for that engine should fit. Unfortunately the 1E50QMF isn't often cloned, so parts are hard to get.

That link you sent me to pmtuning has some. I have a few mods I need to work my way through then I think I'll try them. Hopefully before summer is over.

Sweet, let me know. I'm currently working through reviewing a new head on my Buddy, but I wanna keep on top of mods for the other bikes as well.... Now if I could only find carb jets bigger than 155....

[B02S4]

... scooterworld Guam has them. Dunno.

They did, last time I checked.

[B02S4]

.... Unfortunately the 1E50QMF isn't often cloned, so parts are hard to get.

I would call it more of a bastid knock-off than a clone.

Its closer to the actual Minarelli specs than most China clones are, with the exception of the long stroke crank. Its just as close as the Buddy 125 is to the GY6 152QMI anyway... Same idea, its a 100cc 4-stroke with a stroker crank.

[B02S4]

...Its closer to the actual Minarelli specs than most China clones are, with the exception of the long stroke crank...

I hear ya, although the exhaust port is flipped, the deck height is different, crank journals are different, & other associated small stuff is different, too.

It would certainly be easier to get performance parts for the 106.2 if it was an actual clone.

i need to look again. do you remember aprox cost with ship?

Heh I understand that. Gotta love clones

[Major Redneck]

iv done a small airbox mod 1.10 jets and have now added the prima pipe that comes from scooterworks (lightly used) i noticed right away of the less vibaration,,, the footboard dont rattled like it has from day one at that right RPM that makes it do it... its not as loud as the MRP one i have on my 50cc (thank god) to me the engine does run smoother...

[Ray Knobs]

FWIW I didn't lose any speed or top end with the prima. I don't think I gained any either. It did get about 10x louder.

as of now we are SOLD OUT of the pipes.
i will have something else made shortly. probably in a different style this time... any suggestions?

Hey Tony, something on the order of the Prima, but with a properly designed headpipe & expansion chamber, & a silencer that really works.

The RRGS V8 style pipe needs a smaller diameter/longe stinger to get the most out of it with a stock bore, stock carb, & intake manifold. I've been experimenting with a supplemental silencer for it.

[Major Redneck]

im not all that happy about how bright this yellow turned out,,, but im going to paint the bike RED red...



wonder how hard it its to get the Rattler 110 off the side in order to get it back on after i paint it red???

[nissanman]

Very easy. Heat it up a little first with a hairdryer. Mine peeled off real easy.

so you want something made for the stock motor?
the V8 pipes were actually tuned for the BBK
it's gonna be a little difficult to make a quiet aftermarket exhaust but i will try

Do you have a source for the BBK for the Rattler? I know there's some definite interest from some of us in picking one up.

[tumon-ninja]

i believe i have 5 or 6 bbk left in stock. some here on the forum have already purchased and tried it already. i believe there might be another thread here about it. if you are interested just e-mail me or PM.

[Spawn]

Newb question what is BBK?

[bigbropgo]

Big bore kit. There is a handful of kits for the 50 but one that is made for the rattler has been tough to find.

PM sent.

[Major Redneck]

on the prima,,, is it me or ??? does it get louder the hotter it gets??? why???

and the hotter it gets does it change the propertys or proformance in anyway???

[B02S4]

As a general rule, more heat in an expansion chamber pipe = better high speed response, all others things equal.

That generally means header wrap or ceramic coating, though.

if you are interested just e-mail me or PM.

Hey tumon-ninja, any left? I sent you a PM asking about price, and hadn't heard back...
