Stage6 PWK Carbs 21mm - 24mm are scooter racing carbs that extend your HP to the upper limits by adding more air plus alot more fuel to burn. A good racing cylinder kit should be used with proper ports as well as a large racing exhaust. Simple 70cc iron kits with a smaller type exhaust like a ZX 50 will prevent the best performance plus could damage your engine from over heating.
Linhai 300 Delivery
CCW Misfit Prep Delivery
Sept 17 – 19 has Scootertronics out on the road with one of the last deliveries (SC) of a Linhai Aeolus 300 2008 model with seat back rest which makes it a rare bird. Scootertronics does have two left in Blue or Red 2008 Linhai Aeolus 300 (2599.99 75 delivery PDI FREE of course) which was the very last year the Linhai 300 was produced. These sold at Scootertronics through 2011 locally and hand delivered. The start of 2013 I was able to put a few out on the road by adding a strong PDI which included new water pump housing, coolant system gaskets, thermostat plus housing just to be on the safe side since these certain cooling system parts new after sitting and with only a clean of calcium I simply replaced the parts affected so they are new again. Works for me everytime. Sitting that long needed a real good flush and Blue Ice added for coolant. Quick 4 miles and cooling off and not reaching halfway. Will need oil change at 700 and magnetic oil plug installed.
The Linhai 400 plus Linhai 150s and 50s start arriving in a week than we do some testing and upgrades to see what we really have in EFI Linhai 400. The Vog 260 with EFI has worked out very well and is a very good running 257cc scooter Linhai engine that shadows the Yamaha Majesty 250 of which the Linhai 400 will shadow the Yamaha Majesty 400. To get real clear on Linhai and Yamaha. The engine design is the same. I have used Yamaha after market culinders on the LOnhai no proble. Than that just leaves everyyhing else put the panels which includes all CVT parts , variator, weights, clutch and Bell, plus torque springs and driven pulley.
A CCW Misfit 250 also deliveries this week and comes prepped from Pit so it was good to go. This was also done while it was assembly by Scootertronics so we could change a few small parts that make the battery fit correctly. These Cafe Racer style bikes get it done with a fresh look and plenty of performance plus upgrade performance parts that are done before delivery.
A Heist that is getting built now with new controls, electrical, coil wire and cap (POSH) headlight, turn signals )HardDrive Parts) updated, handlebars (EMGO Drag Bar), brake lines are custom made for the bike along with grips, throttle tube and EMGO mirrors. A reverse EMGO Megaphone exhaust will also be installed. A work around for kick starter which does not come stock will be looked at also which a Helix down pipe can be added.

On a corner in Historical Philadelphia on my own ride this little sporty 250 was filling its day on the corner
Lots of history in Philly.
2014 Honda Motorcycle Line Up
After so many years and hundreds of new and used scooters and motorcycles coming into the shop plus the consumers who call the following is quite clear.
Fuel and Air play a huge part in the performance of the 50cc scooters and of course all scooters and motorcycle due to the golden rule of air fuel and spark and away you go. At Scootpower’s very Scootertronics jets play a huge role in getting the scooters with the correct amount of mixture and velocity.
Keep this ratio of fuel and air on the rich side the air cooled scooter and motorcycle runs better that running lean which a vast majority of scooters are running lean once they leave factory for the US EPA which has all this crazy EGR hoses and catch cans all over the place. On scooters I remove all EGR and raise the main jet to 90/95 and pilot to a 45 (50cc stock is 35) 150 to 115 45 on a air cooled four stroke 50cc or 150cc scooter, two stroke 50cc) models to pilot also 45 the main jet consumers can choose 80-120 according to their engine (two Stroke) whether they have an upgrade to exhaust and cylinder or one without the other, a stock Zuma should get a 80 please check yours first with most finding a 75 main. When cylinders and exhaust are upgraded air filters and jets go up for two stroke to around 97 seems to do well in the 17.5 – 19mm carbs above 19mm (21mm) use larger ones due to a high powered pipe and cylinder that has better ports and more ports than a stock iron or a generic iron 70cc kit. Scootertronics carries most sizes that consumers need the most with the round and hex for PWK and a few other CVK carbs. All jets are Keihin for CVK carbs found in Kymco four stroke and GY6 four stroke. Mikuni jets are featured along with Dellorto jets for all two stroke which include the round jets used in Minerlli engine carbs. PWK and Flatslide use keihin jets with using both round and hex sizes. Air filters play a huge roll with jetting. The GY6 50 an UNI Dual Layer is best for stock and slight mods at 70cc with exhaust. The get the most power from a GY6 50cc 139QMB engine is using a “cold air intake” which is really longer tube and open flow air filter that creates the correct velocity of air when added to the fuel delivered to the engine through a
