Scooterotica

right here we go //i have a li150 fitted with an rt195 and bgm exhaust 30mm del 4.9 final drive bgm stater set at 17 static dan set up on dyno 14.3hp and 13.8 lbt it sits at 65 no problem and tops out at 69.4 gps anyway i am on with a 64 special and iv bought afranspeed super tourer to go with the next kit as i am undecided on a mugello 198 a cassa ss200 or another rt 195 so i fitted it to my rt195 thinking it would rev on a bit more maybey another 5 or 6 hp 75 ish i have just flogged the arse off it around darlington bypasses and it wont go over 61mph its a lot faster getting to 60 but thats it what the f//k £300 pound and ive lost 8mph

You'll need to drop the gearing as the extra power is further up the rev range.

It is making more power if it gets to 60 quicker.

Go back to a 15 sprocket is 5.2 final drive

As both above. Your bike is currently overgeared to pull 4th in the revs where this pipe will return the power gain that you're looking for. Don't mistakenly think that fitting shorter gearing is a backwards step, you only need look at Innocenti's own examples to see which way they were going with their 200s:

TV200 = 4.4

SX200 = 4.8

GP200 = 5.2

Thanks Adam I will try it out I am basically getting a good set up for the 64 special so I am trying it out while I decide what kit to go for

have you got a rev counter if not what speed in 3rd before and what speed now in 3rd ,id not be sure on the gearing change may need 1 more on that kit ,,its a common misconception of clubman pipes but they regularly rev much higher than pretty much most of the popular exhausts ,the supertourer will rev on a tuned kit but a low duration kit like the rt will peak early
i would look to upjet too the bgm clubman normally requires a small main jet 115-120 as it gasses up otherwise due to its small outlet ,the fran supertourer nearer 125-128 try jetting first as you might kill it

Hi darrell in 3rd before about48 and now 53 I had a 125 main and I upped to a 128 new plug and Color is a nice brown

You have to tune kit to get best out of fran super Tourer from my experience, the 225 kit i tweaked to work with it originally hit peak power at 6 k and went nowhere . It now pulls to 8.5 k with little drop in tq
I had a rt230 myself a few yrs back, bolt on with jl4 it ran well with good spread of power to 7.6 k .
There a good kit and will pull well with box pipe to 65 mph all day long, however gearing is important too

looks like gearing then ,,have you any spare wheels/tyres at all with different brands of tyre fitted before taking it to bits try a smaller tyre what tyre is on back now ?

350.10s sip tubeless s1 I will try 15 sprocket don't forget I am trying this out for the other scoot so I don't wAnt to make drastic changes as the li150 rt195 runs really well
