imola ppl need advice on additions???

You need to get a copy of Scootering issue 274 from April this year, there is a small block dyno shoot out where all the kits are covered. With prices and HP and good/bad points.

weired 5 mins before i saw this a mate said the same as you. Hopefuly, he will pop it round later as i dont reckon i have that one.

its the Vijay Super Mk 2 that is in there. The NK has an interchangeable downpipe so i assume it could take an larger fit??? What would be the downside of keeping this setup with the imola?

Its a 16t front sproket, sorry.

Also, will a "more" plate clutch make a lot of difference. If things were kept as they were and imola added would it be wasting a lot of potential?

you've got the "Vijay Super Mark ONE" box in that one (10;12;16;19 and 50;42;38;35) which is basically the same as SX150 without the jump between 3 and 4. Also there is a 16T front on it.

Final is 5.29 to 1 with the 16T

Clutch is standard "Surflex B" with stronger springs

Thanks Chris, i am glad you corrected me.

I like the Vijay Mk1 box myself- good all rounder IMO

is there anyone with a scanner out there who would mind emailing me this page (s) my mate doesnt seem to be able to find his. email is my user name at gmail.com thanks if anyone has a few spare mins.

Like Corrado I have done thousands of miles on my Imola so his advice is well heeded.
It is a revvy kit but built right in the first place it is extremely reliable -I've had well over 14, 000 miles from mine - sure I've had new rings / piston etc etc the kit itself is still going strong.
I've ran it with a Clubman - pulls 4.8 (li 150 16 x 46) no problems, Scoot RS -pulls 5.2 (standard LI) and now a JL4 on 5.4 (li 125 16 x 46) and this is the fastest set-up top end wise.
Speaking of final drive ratios its important that you consider how you actually achieve the ratio. Knowing what I do now I would have gone for a gp200 box - it gives the greatest flexibility and is easier on clutch life. A GP200 5.2 final drive is easier on the clutch than an LI 5.2 final drive.
Clutch - only ever had 4 surflex B plates with Taffy uprated springs
Carb - only ever ran it with a 28mm dellorto open mouth or remote ramair
Used the MB reed valve inlet, with short rubber and fitted the Yam Boyesen dual stage reeds
Anyway I won't bore you with the trivial details suffice to say you won't regret buying it - its like a baby TS kit.

I`m in a similar position to Druist regarding the Imola kit. I`ve got my hands on a blown one so need a piston and crank to suit.
Mine`s is going into a S2, I weigh in at 15 stone and 2 up would be good the odd time.
I`ve a Imola-flanged Clubman to go on it with maybe a PWK 28/30 carb on an MB manifold.

Is there any advantage to sticking a 60mm into it to increase torque or maybe a 110mm rod to alter the port timings?

How did yours go with the Clubman Soullad?

Theres a big difference in power between the old imola kit and the new one with revised cylinder head and I think inlet?
I built one earlier this year and it made 22.5hp on our dyno with a JL3 and a 30mm mikiuni.
Camlam brought theirs up for the smallblock shootout with a JL4 on and it made the same so no fluke.
To put it in perspective a std TS1 makes 20hp on our dyno.
What was most impressive though was the torque. I haven't got the figures to hand but it blows the old imola away everywhere. So much so that 5.2 was too low geared on this bike and needed either 5.0 or even 4.8.
What seems to be critical on Imolas is that the transfer entrys on the casing are fully opened out to those on the barrel. This can leave the gasket face very thin on Italian cases so it may be worth welding around these and refacing the gasket face which is what I have done before.
Not scientific but I've seen a 4hp loss when this hasn't been done although this is comparing two different Imolas but with similar exhaust,carb etc.
I wouldn't expect to see the same difference on on a TS1 so it would seem to be critical for the Imola and maybe other smallblock motors. I wouldn't bother with any other tuning they seem fine out of the box. match and flow is the thing here.
Crank wise I've used a MEC on the ones I've done although I have had the pin welded. They have been fine so far but I may have used something with a Jap rod on the last one if I had known it wwas going to be so powerful. I wouldn't trust a MEC in anything much over 20hp but I believe them to be fine otherwise.

Al, What are the differences between the old and new Imola's is it an obvious visual difference or revised port time areas..??
