The Scooter Shop at Scootertronics: Scooters with Tommy Thunder

Tommy Thunder talks about scooter engine builds for Scootertronics

Hey Tommy Thuder here . Just finished up an upgrade at the shop down at Scootertronics man it really rips . It was an RSM 50cc Blazer and it was pretty slow from start to top end . So we decided to add an 80 cylinder kit and head.We also installed a Prodigy clutch and clutch bell , Kelar belt and Doctor pulley slider weights (5.5 gr.) I also installed a larger jet and an Emgo air filter. When I pulled it down off the lift it really ripped.I did think that I might try a blue torqe spring though or up a little on the weight for this scoot and owner but we'll see it does great now!

When doing these upgrades
jetting and air filter should
also be done.

DONT FOGET THE JETS

There are now many great parts to make these 139QMB engines rip and We have tried them all and we know what works best. I also am tring new parts,upgrades and knowlage everyday to make these scooters do their best in performance and durability.I have a blast building and testing our scooter projects . Here is a few pics of some other engine I am doing and have done. Look at the piston size differance from stock to upgrade

This one is an Apachee 50cc four stroke that got an 85cc kit larger carb and whole trans kit.

This one is one that got an 85cc kit a larger carb fuel full trans. Also got an MRP V8 pipe. That really brought out the power .The scooter also got hot coil , CDI, and fuel system upgrade.

When doing these type of upgrades we recomend using a Kevlar drive belt.To handle the power.

I have built many scooters and if you are building your own or you have us or someone else (Good Luck) do any of these upgrades alway use a Kevlar belt . If not you will not get full potential of the power and you will also get a little more just out of the belt. I ride scooters on the road, I race them we ride them in the mountains were I live and they are put to the test.The first thing that will fail if not upgraded will be your belt.
