Although I’m a dire 2 stroke fan and will cling onto them kicking and screaming, unfortunately 4 strokes are the way forward with emissions laws and so forth, but they’ve always been slow. Well not anymore!
The amount of tuning parts for Chinese scooters is surprisingly low considering they’re generally the best selling scooter when you group all the various brands together who sell the same basic scooter, but there’s now enough parts out to get a fairly good performing scooter, although it still won’t be a patch on the 2 stroke scooters.
Unlike the 2 strokes where the exhaust makes quite a large difference in power delivery, 4 strokes aren’t affected as much so firstly I’d recommend fitting a big bore kit, after all, there’s no replacement for displacement.
Airsal manufacture an 80cc big bore kit for the 4 stroke Chinese scooters, which is a surprisingly high quality piece of kit, with an Aluminium cylinder and nickel silicon carbide barrel coating for minimal friction, which helps when you consider how many piston rings the 4 strokes have!
Fitting the Airsal big bore kit is fairly simply on the Chinese scooters, although it’s still a lot more complicated that two strokes since you’ll have to line the cam shaft up afterwards so if you’re uneasy about there it’s worth forking out for a qualified mechanic to do the job, since if you get the cam shaft timed up wrongly you can end up with bent valves and damaged pistons.
After fitting the Airsal 80cc big bore kit, your Chinese scooter will want a nice meaty performance exhaust to compliment the new kit, and LeoVince now produce the goods. It’s the 4road model exhaust, which is a straight through downpipe with a stainless steel can. After fitting both of these it’ll be worth going up a couple of sizes on the main jet, carrying out plug colour readings to make sure. The Airsal big bore kit says it requires no increase in jet size, but with a LeoVince race exhaust fitted as well it would probably benefit from a few sizes larger on the main jet.
Fitted both of these? Malossi now produce their MHR Multivar Variator kit for tuning your Chinese scooter, as well as a Kevlar belt. Normally I don’t recommend changing belts from standard when road tuning any scooter as most standard belts are Kevlar anyway, but the Malossi Kevlar belt for the Chinese scooters is actually 5mm longer than standard. This combined with the MHR Multivar Variator will give a slightly better range of gearing, helping both acceleration and top speed.
Done all this? Want more speed?
Tough luck unfortunately, the Chinese scooters are built as budget commuters with excellent fuel economy, they’re not designed to be speed machines so you’re options are to wait until someone produces aftermarket performance cam shafts for them or upgrade to a 50cc 2 stroke or a bigger bike.
