Ducati 135 LC  Spotted at USM over there. Super Cool! for me

I wonder how the owner of that motorcycle feels riding a so-called 'Ducati'.

Curious to know how would he or she feel when a real, genuine, piece-of-art Ducati parks up beside that thing.

So, my engine now has a 62mm block / aftermarket valve springs / camshafts.

Do these/other engine components require modification when replacing my current stock CDI for a racing CDI?

Or just plug and play?


EDIT: Or do you recommend a carburettor before the CDI?

Some say the CDI is the most effective in bringing out the most of your big block;
others say the carb is it's best friend.

cdi change does bring out the most of ur big block because.. bigger block usually have more power and the stock cdi limits the power.... but limitation of the cdi is the Key to longer lifespan of ur engine.. =) lifespan = less maintenance

but of course this does not mean that u must use stock cdi.. buy a cdi that is adjustable.. =) but in ur case.. 62mm block, tune properly for top end power.. i bet ur bike need a koso meter already.. because finish meter easily in stock.. =) and then make u gila because the jarum kacau ur top speed.. only way is cut ur needle short..remove the yamaha logo in ur meter..

but according to other members here.. they recommend u change bigger carb.. bigger carb means bring in more air fuel for ur engine.. =)

but in my area, my foreman did not recommend to change carb, he says stock carb more than enough.. 61mm with stock carb can give stock meter hit 220km/h..

after all.. tuning a carb need pro foreman... tuning a carb is more difficult than changing bigger block... =)

Thanks.
So if I get a new CDI, adjustable as you say, is it plug and play?
Or must certain engine components be removed again for some modifications?

Before going further, need to know what is the compression ratio of your new setup. With this, we can tell if your engine can go high RPM or not. Only then decide to switch bigger carb and CDI. I'm no expert, but this kind of thing better leave to experienced foreman.

Can your engine go high RPM now? What is the sprocket setting and max RPM at top speed now?

It now hits 8k-9k rpm compared to the 7k rpm limit when this bike was stock.

I haven't tested the top speed and max rpm yet. I doubt the top end increases by much - the top end RPM should probably increase to 8k compared to the pre-modified 7k rpm at top speed.

Sprocket is stock.
