Hi,

I was wondering if anyone out there in Trials land has had a 320 4 stroke engine lock up whilst trying to kick it over / start up. This has recently happened to mine, a 2011 model, and we're trying to sort out where the problem may be. It locks that bad that you can basically stand on the kick starter & it wont budge, but put it into top gear & roll it backwards & it unlocks, give it one kick is fine but then locks again during a second kick.

Any help or information would be appreciated, especially if someone else has had a similar experience with one of these & as only a handful of these were sold in Australia information is limited so I'm hoping someone out there may know something.

Thanks in advance!

 

 

Have you checked the condition of the kickstart quadrant / gear ?

Does it do this with the plug out ?

maybe crankcase contains a lot of petrol

Will the rear wheel turn freely without resistance while in neutral..?

get it working and then sell it.

Hi all,

Its taken awhile (mainly sourcing a flywheel puller which I've managed to borrow with thanks to our importer) but i finally have answers - the top section of the front plastic cam chain guide broke off & lodged down in the bottom cam chain sprocket, locking up the engine when i went to start it. Hopefully now, with a few new parts, we'll back underway!!

Thanks to all for the replies & help.
