Scooterotica

Stage 4 200, 25mm dellorto, looking to fit one but not sure what to go for.

I run an LTH one on a JB tuned Rapido.. Brilliant !! imo.

LTH are great ,SCOOT RS are good also

i use the mb shorty,great piece of kit.

Cheers. Scootrs look ok pricewise, but small or large?

Small one looks like a copy of the CNC one that LTH originally did, fits with very little modification, large one on the other hand needs quite a lot of cylinder fins removing.

What's the difference between using a small or large one?

Bigger reed valve on the bigger one.

Using the small one on my Muggy 225 with Harry Barlow TS1 piston and no other mods to barrel or piston. Seems to work well with 26mm PHBH. Had issues with frame clearance and had to remove some material from the base of the manifold but that may be Mugello related. From memory there's no size options on the reeds or sizes with the Scootrs one whereas the LTH ones come suited to different carbs and different qualities of reeds.
Scootrs one is much cheaper though.

So how does this affect things? I mean, why go to all the trouble of trimming down fins when you can just buy a smaller one?
