My scooter came with this engine. I haven't had much time to ride it yet.

Sorry to pepper you with questions Matt,,, you runnin a 2 valve head or 4?,,what kind of piston are you runnin?forged or cast?,,,i got a million more but i don't want to completely swamp you,,,lol Cyborg, We didn't balance anything since we built it in the drag racing parking lot the day before the races. Our race engine that we brought blew up right as we got there, so it was a true off the shelf parts test. No porting or polishing, no special attention but she ran like a champ and won trophies. Forged piston. Our PN is 169-341, but for some reason the part isn't displaying on the website, so I'll have to fix that... Also, for this build we stuck with the 2v head instead of the 4v. We wanted the stout low end that you get with a 2v over the free top end of the 4v. Maybe next time we'll build it out with the 4v as she got a little cattywompus on me at the line. Good stuff!

Hey Matt, thanks for the reply. yes, that does answer my questions. However, now I have a new one!  The Hoca carb you listed says it is a 2 stroke carb. Did you have to do any mods to use this type of carb? Also, what are the pros/cons of using a PWK over a CVK? BTW: The Cyber Monday sale was awesome! I purchased one of these motors and will be publishing a video review later. |

thanks,,,1/4 mile?,,,,1/8th?,,,and what numbers were you running,,,,bracket racing? We were running 1/8th mile, both heads up and bracket, although we only ran the NO2 during Heads up, so bracket was slow going since the bike was geared and weighted for running NO2. I was doing pretty good in bracket, but ended up having a really stupendous light and broke out by something like .01 right at the end. It was a bummer. Heads up though we were running high 8's if memory serves with top speeds in the high 60's/low 70's. Tom here is looking for the time slips, so when he finds them I'll update with more accurate information. This year if we find the time to go racing again, we'll probably try building with the 4v head and stroker crank. The HOCA and other Taiwan product that we have was actually going faster than larger Taida builds for a fraction of the price. Matt |

I purchased one of these motors and will be publishing a video review later. Yep, the PWK carbs are normally used for 2T applications, but really are just a Flat Slide Throttle direct style carb that has been used in all kinds of racing applications for pretty much ever. We just used that for the instant throttle response that it gives, and is also much easier to tune NO2 with this style of carb. For street use I'd still go with the more standard CVK carb though. It'll provide plenty of fuel with a more friendly application of the throttle, which is far better for the longevity of the engine and your transmission parts. Matt |

Funny you would like a cv over a slide carb,,, I'm the other way in that,,, can't stand cv carbs,, I go to a slide as soon as I can,, the Stella has a direct carb but it's an antiquated design and too small for the application,, so I'm going up 3 mm larger with a freer exhaust that's it for this boat anchor ,,,

I honestly think that for the vast majority of street applications on a 4t bike a CVK just does a good job, and tends to do so trouble free. Slides are great too. Personally I run a slide on my P bike, (Because it's the hot rod out of my bikes... Always broken.) but on my Daily GT200 I'm all about the nice linear response from the stock CVK.

Matt Thanks for taking the time to answer my questions..... I did a little more searching about PWK vs CVK and learned a great deal... These scooter forums are awesome! Anyhow, I wound up selecting the 30mm CVK Hoca carb to go with this engine. How do you think that carb will work out with this 180cc power kit? |
