just bought a standard jet 200 and was thinking of updating it with a modern top end for touring/reliability
any suggestions/advice on how to go about this would be great..

If you can't do the work yourself then find a good (recommended) dealer/engine builder to do the work for you.

If you post where you live i'm sure you'll get some recommendations on here.

Depending how far you want to go be prepared to spend thousands of pounds.....

Cylinder kit: £500+
Crank: £150 +
Carb': £150....ish
Exhaust: £300.....ish
New bearings, seals, chain, clutch, etc: £200 +
Advance/retard ignition: £100
Then there's new cables, fast flow tap, long range tank, etc

It's a question of how much over £1500 you spend. That's the materials, then there's labour....another £1500....ish give or take depending how much work you can do and how far you go with the rebuild.....good luck

The set up on my Eibar Jet 200: GT200 kit, BGM clubman, and 28mm dellorto. Majority of my riding is around town so I was after mid range power band. At around 115 -120 kmph I run out of gearing on the standard gear box. Regular 4 plate clutch is fine. Changed front sprocket to go up one in teeth to make use of the extra torque. I'm happy with it. But be aware that kits are all designed for Italian lambretta. The Spanish frame was strengthened and has more of a gusset where the silent block goes in. The effect is the reed valve was hitting the frame tube. I had to go back to a standard length shock (a certain year of yamaha works) and grind down the gusset in one spot where it was preventing me from putting the carb attachment rubber in place.

Leave it totally standard. Anything need renewing? If so replace with like for like. If it's touring/ reliability you're after you've got it already. Pleasure to ride from urban thro to sitting at 55 mph all day long. Wind & hills not a problem in 4th in the main. The sx200/jet set up all day long(with electronic ignition )for me.

thanks for all your advice lads.
i am keeping it standard and as eibarlad says just going to replace bits when needed.
it already has a 12volt kit so a service and then clock some miles up.

Changing the pipe is a relatively cheap upgrade, simple to do yourself.

If you want to keep it stock, a clubman pipe had the looks and is a performance boost for little money. And ask to have your squish checked. The clearance between the head and the piston. Simple adjustment that can find lost HP.

A SIL stage 4 barrel with decent piston upgrade, skimmed head, a decent clubman pipe and up jetted carb to suit and for under £200-225 you'd see a worthwhile increase in performance.

There was a good (excellent !!) article in Scootering about improving the BHP of a standard 200. Darrell Taylor wrote it and it's well worth a read before forking out any money.

Think the above is about right not too much retaining the standard look
