I'm after a sports exhaust for this scoot now. Will any of the Honda pipes fit ?

Damn! That's a '99? 

Thing looks brand new. Take that front fender off. Looks better that way

You have to figure out which engine yours is, look on the kicker side and see if you can find an engine code. the super fever 2 uses a sc10a, if it says that you can use any pipe for 94+ honda elite/dios. If its the other af05e engine your limited to choices and the leo vice sp3 is the only one thats readily available.

the annual safety check in the uk states the front fender must be fitted. I'll check the engine number tomorrow

Lol thankfully I've just invested in the Isle of Man !
Have a look on YouTube. This island has no speed limit ( except in the villages )
Perfect for us bikers ;-)

I've cured the starter bendix chinking on the outer variator noise.
A small spring coated in grease pushed into the outer casing bendix locator hole ( yep, just made that name up) and now it idles nice n quiet ;-)
Might try another half a mill off the boss next?

The ped now hits 53-57 mph on the flat dependant upon wind strength. 61 mph downhill

[LoveMyKymco]

At 61 youre almost at the stock gearings limit. Stock gearing 64 is my top at near 13k rpms on a ported polini corsa cylinder kit and a polini variator/malossi ramp with the white "reinforced" malossi contra spring. You really feel like youre flying at 60 on them. Be careful tho as your brakes are seriously not up for quick stopping after 40.

I know we are close to the last few drops. I'm gonna try a 33 mm boss with a .5 mill shim, hopefully the spring will prevent the bendix from fouling the outer variator. Scoot currently has 7g rollers fitted. Need this damned snow to clear so that experiments can progress !

Ok, my son managed to save some money and tonight we fitted a tecnigas next r exhaust. Surprisingly quiet for a sports exhaust, or it was until I pulled the wadding out of the end can.
This has changed the characteristics of the bikes pull. Looks like there's more experimenting with variator rollers. Will try going lighter and going heavier. Will keep u all posted.

[naughty lee]

It's hit 63 mph today, lighter rollers have been fitted which have improved its take off. I've picked up a new plug for it which is going in tomorrow. From here we can work out if any carb adjustments need making.. Will keep u guys posted 

[naughty lee]

Ok, So I fitted a new spark plug yesterday and ran the bike for about five miles. Inspected the plug, it looked the same as when it went in, So it's lean. I've dropped it in at a local scooter shop because of time restraints and asked the chap there to change the jets and rake the carb out. Will update once the works done

[naughty lee]

I got the bike back from the ped shop with five jet sizes over.
Ran it on a new plug, it was still lean, up to six sizes over, still lean. The guy in the shop gave me some jets. I fitted the 7 th, the bike was flying but still a tad lean. gone up another jet size, now 8 sizes over stock. The plug is starting to brown off. Re set the air mixture and fitted an iridium plug. 60 mph on the flat. Gonna warm it up tomorrow, pour some redex onto the piston and take it on a downhill challenge, see if it ll hit 65 mph

[naughty lee]

Snow in march! Wtf ?
Testing postponed. Bike now has 6g rollers fitted. Will continue testing when weather improves

[naughty lee]

We seem to have hit a barrier now, I think the 6 g rollers have lost us a little top end. The bike still indicates 60 mph but we have seen 63 mph in the past.  I'm looking at mixing in 3x 6.5 gramme rollers into the mix and probably calling it a day... Or should I buy a race variator ? Lol
