Sprockets & Chain Combination

[Bilko]

What sort of sprockets & chain combination would suit a Muggy 186 on a full frame with passenger?

Thanks

LOL! an old taffspeed copy. But possibly changing to an 80's OTK fresco.

THE fresco is REVVY ID START WITH STANDARD 15/46 the taffy copy will depend on which one it is if its say a 1 or 3 like the JL 3 YOU MIGHT PULL 16T FRONT IF ITS A 2 OR 4 FORGET IT UNLESS ONE UP THE 4 IS VERY REVVY I BORROWED ONE FOR MY TS1 AND IT WAS RUBBISH ROUND TOWN AND WOULDNT PULL 4TH UNDER 50 VERY WELL BUT WHEN IT GOT INTO THE POWER IT FLEW, THING IS WHEN OUT WITH THE LADS ON A SUNDAY I WAS BETWEEN 3RD AND 4TH ALL THE TIME PUT THE PM ON SMOOTH AND POWER LOWER DOWN

Revvy pipes and pillion passengers, avoid one of the 2. In my case it's avoid passengers .

LI150 box - I use 16/47 which gives 4.99 final ratio, IMHO thats the best all round set up for the mugello.

I run that on my TS1 225 group 6 racer......and it howls!

Gonna try 17/47 on the RB20 to see if it will pull it, but i'm 12.5 stone and its in a lightweight cutdown, so shoudlnt be a problem.....if it is, i'll switch to 16/47 also.

But for 'big lads' on full frames with luggage passengers etc, the Li150 on 16/47 is a better choice than 17/47.

Thanks for the advice and input.
