Ive recently had my T5 resprayed and engine re built including new exhaust cylinder kit and piston. I had a seizure after about 50 miles or so, I had been taking it easy and not doing over 40 mph. I just lost all power and the back wheel locked. Ive also got a leak out the back of the carb box, is this whats causing it? So I got a new piston and rings then a couple of months later I had a similar experience though the back wheel didnt lock this time just a loss of power and I got the clutch in before the back wheel locked up. After about 20 minutes I was able to get it started again and rode it about 5 miles home. I'm a bit concerned about taking it out again dont fancy being thrown off or stranded in the middle of nowhere. Any ideas what could be causing this, everything was fine until the rebuild.
Cheers

either theres a air leak round carb box/carb flange ,could cause a leak aswell , or your jettings off , youve a new exhaust n cylinder on but dont say wether there stock or aftermarket , an also need to say what jetting n filter your running , am guessing after re-build you didnt dial in ya jetting/carb an are running lean giving heat seizures .

Cheers Henri
Everything standard. It was a new Sito Plus exhaust, can't remember the jetting off hand but it is supposed to be ideal for 200cc.

Your jetting for a p200 with sito+ is around 118, 120 main jet, if thats what you have.
But as Henri says, you coud well have a leak at the bottom of the carb and/or carb air box.
Id suggest removing carb and box and refit it properly.
Also check the carb has not been warped out of shape while youre checking it out.
So, do you have a stock px200 motor with sito+ ?

200cc , a t5 is a 125 , should run a 24/24g carb with 110 main , be4 atomiser ,an a 50 pilot jet or 100/100 if got air correcter , an 120 air correcter ,
a 200cc runs 24/24e ,118 main, be3 atomiser ,160 correcter jet an a 55/100 pilot ,
so if still stock barrel an sito plus pipe up 2 sizes of main should be close ,an a be3 atomiser is 2 orders of leaner than a be4 ,made worse by a air correcter jet 2 sizes larger =lean mix from 1/4 throttle to 3/4 , a over rich pilot an main jet , as you was running in right where you had the throttle was lean mix=seizure , would of done better at WOT , an tickover , mind thats where most t5 pilots use there throttles , off or on ,
get it set back to stock carburation with a 2 size up main jet ,
others on here might know better as i dont run a t5 , but jetted as a 200cc is wrong , just looked on scooterotica an guys on there with serious tunes an 28mm carbs are jetted that big or bigger , H

Update - been running well for over 6 months now. It turned out that the carb box was warped and was causing an air leak. So I replaced the carb box and doubled up on the gasket between carb box and engine to stop any oil leaks and I've had no problems since. Cheers for all the advice.
