MRC Forum- brought to you by www.morini-riders-club.com

I just purchased a 1983 SEI V Sport with 473 miles on the clock. Due to the very low mileage and mint condition, I want to keep the bike original, but since I will be riding it (can't resist) I will need to make some rideability modifications. Had a 1975 Drum brake sport, but like an idiot I sold it last year, so I needed to scratch my Morini itch once again...Questions, since I've never had a 500 before:

1. What are the best rear sets, Tarozzi? Are there any others? Will the kickstart lever extender from NLM make it so the stock lever clears the toe peg?
Also, bike has left hand shift, right brake since it is an 83. Is there a specific Tarozzi set for these bikes?

2. Has the ignition pick been improved on the 83 models, or are the NLM pick ups required? My 3 1/2 did not idle reliably until I put on the NLM pick up.

3. What batteries are suggested given the marginal (for the ingition) starter motor?

4. Bike has pod filters, which is only mod on an otherwise bone stock bike. Does bike run better with stock airbox? Is stock airbox and manifolds still available? My 3 1/3 did run better with the stock airbox. Also, are there rubber manifolds that can support the carbs with pod filters, if these are kept?

I know, lots of questions, but thanks for your help.

Was this the 500 on Ebay? Beautiful machine Congrats

Yep, that is the one, thanks.

On a related topic, does anyone know if the 350 ad 500 airboxes are interchangable?

Thanks

I know a 500 airbox won't fit a 350 frame.

If you can't track down an airbox, then make up a plate that bolts in it's place and mount your pod filters on top. That means that both filters see the same air conditions which is half the battle for good running.

You can then use standard intake elbows to connect and support the carbs. NLM don't have originals as far as I know, they have some sort of universal rubber, but you might still be able to get original items here; http://ricambi.mayoreric.com/

Tarozzis are usually the easiest to find. They are not necessarily the best, but unless you make your own rearsets, there are few alternatives. Most rearsets mount on the Morini in the same fashion as Tarozzis, so it is not much of an issue. Small adjustments to any rearsets will be required to make them work properly, of course.

The stock airbox works best for the 350 in street applications. My guess is that is works best on the 500, too. Keeping the front-facing filter out of the breeze is a good alternative.

Finally got the bike, which looks brand new. Had to kickstart it, as the electric starter was not up to the jo. What battery are people using to improve this? Also, has paioli piggy back linked shock, which are too soft, even with preload maxed out. Does anyone know the max PSI thst these are supposed to run?

thanks

Sounds an incredible find, but first,

I put a 13Ah Hawker Odyssey on a 500 Sei. It gets attention at shows as people keep asking how you start it given that the kickstart is missing.

Buy the highest cranking amp battery you can, the Ah rating is pretty much irrelevent. I made up a new battery tray to hold the Odyssey.

I can recommend Varta batteries.
