I`m looking forward to part two.....

[@deanodrives4966]

Having owned off road pit bikes, that thing would be a huge laugh on the road/Green lanes

[@billconnor103]

Clever boys hope it quick but I would of thought you would have to tell DVLA because of bigger engine or maybe not 😜

[@Thegeordiemonkey]

Use a carb spinner so you can mount it at different angles.

[@madonrc83]

Great work guys! Looking to do this mod myself, can you send me a link for the 140 engine please

[@user-dv8yn6hu8q]

Where did u guys pick the back lights up from? Are thoose stock on thumpstars? Also what did you do with the engine? 🤷

[@joegoodwin5044]

do you know if it’s possible to make the normal thumlstar 125 road legal? i can’t figure out where the battery goes

[@reecemorse1936]

What’s the perfect oil amount in ml

[@highlandrab19]

Could you not start with the 140 high lift bike and then add your own lights to make it legal?

[@diversionbob8482]

Are you going to try the 125 with the 20mm restrictor gasket opened up to 26mm?

[@motorsforthemasses]

That is a thought I had had already.

[@kieranlee9901]

I got one last week but can’t start it with electric start or kick . Done the choke ect Ino it’s note major am doing something wrong. Could u give me abit of advice pls thanks

[@motorsforthemasses]

Did you buy it through a dealer? Was it running when you got it?

[@kieranlee9901]

Yes mate it’s from a dealer brand new when they delivered it they already put petrol n oil in it. Electric start is not getting started or kick. Gas is on choke on Ino it’s only something little what am not doing right. I can ride them but no good on that side of things thanks

[@adamtownsend4175]

We’re did u purchase the engine ?

[@motorsforthemasses]

Direct from Stomp

[@leonardodahumanoid4344]

I thought the 140 sounded much stronger.
