Mitch.W Posted May 8, 2013 Author Share Posted May 8, 2013 hmm how big are the factory airboxes? i cant seem to find any parts for these on trademe or ebay? any other places that would have parts? Quote Link to comment Share on other sites More sharing options...
Benno Posted May 10, 2013 Share Posted May 10, 2013 Can you get these things road legal with lights etc added? Quote Link to comment Share on other sites More sharing options...
AndyGal Posted May 10, 2013 Share Posted May 10, 2013 Iv got a spare factory airbox if you want it they are pretty big and ugly though will make it look shit. also is your choke hooked up? Mine wont start without choke unless its warm. Quote Link to comment Share on other sites More sharing options...
Mitch.W Posted May 10, 2013 Author Share Posted May 10, 2013 i dont know if i can get it road legal if could that would be awesome!!! nah no choke hooked up but it can idle long enough to get pretty warm. i have a feeling its the points i couldn't see them moving at all when i went to clean them? yeah factory airbox would look very ugly. do you know who or where sells parts or just has spares for these thing? Also just found out that the frame is a honda qa50! sweet. Quote Link to comment Share on other sites More sharing options...

Mitch.W Posted May 21, 2013 Author Share Posted May 21, 2013 so i adjusted the points gap roughly and it ran! it ran rough but it ran! now i cant really find anything stating the points gap for the v50? can anyone help with this? churrrr Quote Link to comment Share on other sites More sharing options...
Rookie Posted May 21, 2013 Share Posted May 21, 2013 A business card. Quote Link to comment Share on other sites More sharing options...
Rookie Posted May 21, 2013 Share Posted May 21, 2013 I should clarify that, a business card will do until you get the proper measurement, that will most likely involve a DTI on the piston. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted May 21, 2013 Share Posted May 21, 2013 flywheel should have top dead centre marks so no need for a DTI lol.. set to top dead centre, and set points gap to what ever/business card. don't underestimate what a good hard run can do for a 2 stroke engine that's not been run for a while. don't read that as thrash its tits off though.

Rookie Posted May 21, 2013 Share Posted May 21, 2013 No, a lot of small 2 strokes require the points to open a xy mm before TDC, hence you need a DTI and a multimeter to set them properly. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted May 21, 2013 Share Posted May 21, 2013 then you set them to crack open at the F (fire) positon on the flywheel, you can see when they crack open with a multimeter or test light. I really don't know any scooter mechanics that include a DTI in their tool box (though I would love one for other reasons) they are just a bit overkill. but in saying that, when they open at the fire position, once the flywheel gets to TDC, they should be open at the pre determined points gap.
