Cn250 performance parts
 

Does anyone know where to get parts to modify a Honda helix? I'm looking for a performance clutch/Bell housing and variator. But mainly looking for gears. I'm wanting different gearing for more torque. Even though it goes up to 70mph with ease I don't need it to. Im wanting my 0-60 to be better, so I know lighter rollers too an extent, better clutch/springs.
But I'm looking for more info on better parts for this engine, are there compatible scooters that will work that have more parts available.
Any info will be appreciated. And yes I've researched. Looked this info over before I even bought the bike but I still bought it haha.

I've owned 2 Honda Helix's and 1 QLINK Commuter (same thing with terrible quality). I had fun with the 2nd Helix. I had the 300cc big bore, fast flow air filter, variator, clutch kit, proper jets etc. I do recall they sold gear-up kits for a higher top speed, but I passed on those. I also had my stock head reworked by a head specialist. I cannot recall who the heck I ordered from. I will look in the garage and see if there is a old invoice or sticker or any other clue. Your motor is "based" on a CN250 engine if its a vertical cylinder.

Correct, it's a Chinese scooter but it uses Honda helix engine (clone) but identical other than that. I'm looking for websites that reputable and have good choices in parts too. I can't decide if I want the malossi clutch or Dr pulley. Also new variator with weights I'm also looking for gears. I don't care for top end as long as I can do 60 rather then 70 something I'll be fine. I want more torque.

Love the first picture. For those that think Chinese products are the same old crap, take note that his bike has a Gates Powerlink belt in it. That probably points to better components spread throughout.

That was my first reaction taking off the cover and seeing that. Those are the same name I bought for my Honda ruckus until I bought Polini that is.

It was so long ago that I cannot recall the store I got the parts from. I looked everywhere. Will continue looking. I remember the 300cc kit was made in Taiwan, the clutch was Malossi, the variator was Malossi, rollers were no name (still have some floating around for the Malossi) and it all worked really well. I used a Lambda kit and a air/fuel ratio gauge on the stock exhaust to help tune it. When I wreaked the hot rod Helix a friend stripped the transmission for his Big Ruckus (he said it fit and worked!?) and another friend took the motor and ECU. Bought it back from the insurance company for like $100 or something crazy. Miss that scooter sometimes. Now I got a Honda SIlverwing scooter sitting in the garage. Took it as a trade to help a friend out. Its a piece of crap so Im kinda in pause mode right now.

I'll keep looking around and researching, thanks for the update.
Do you have anything you'd be willing to sell to me for the cn250 motor? If you have anything leftover haha

That was a long time ago. I was helping the Shriners with their parade Helix's. Some of them also had a Helix for personal use. Last but not least was the friend with the Big Ruckus. He grabbed all the transmission stuff. The last of the stuff I had all went to my local Honda dealer. You might wanna try Scooter Swap Shop, as Brandon seems to be able to locate weird/hard to find parts or point you in the right direction. He recently did a new-old-stock 300cc bbk on a Helix. I never went into my CF Moto/QLINK engine so Im personally not sure what is different. But take the time to tune the stock transmission and you might be happy with the results. A performance variator would be next. I wouldn't replace the stock clutch unless you go with a bbk. Also note that the only gear kits I saw were for improving top speed.

Well I'm having an issue with my clutch now so i figured might as well upgrade the pads. I've researched it and the shudder on take off is either stuck roller or clutch pads, took both out cleaned and re-greased the rollers and it went away for a day then came back. So I'm assuming it's the clutch since I didn't have stuck rollers, I also read that people were very happy with the malossi or Dr pulley clutch with new variator. They said it made it feel better at higher speeds when letting off the throttle then giving it some gas.

Shudder is either a glazed clutch bell/clutch shoes, weak springs or a re-grease of the rear sheaves is needed. Also, I have never heard of anyone greasing the rollers in a variator. Not saying its wrong, just never seen it done.

Yeah I cleaned it off and kind of scrubbed the pads to make sure they were clean. Didn't help for long.
And I never greased the variator/weights but all researching everyone did so I just put it on the weights and the variator clips(can't remember the name) but I cleaned it all for 30 minutes scrubbing it all and getting off the old grease. It might be the springs so maybe I'll just get new pads (OEM style) and probably a polini, Dr pulley or malossi clutch Bell (better than OEM) and Dr pulley springs and just "repair"/ enhance the clutch and be a lot cheaper then a hit clutch and see if that helps.

Yes, the HIT clutches are nice. Just not really cost effective unless you go BBK. We always run the factory clutch bells unless we can find one with cooling fins or one with a knurled inside. Most of the time the cooling fins either rub the engine case (dont fit right) or the fins come off the clutch bell because they were press fitted sloppy or the bonding agent melted! I used to do build sheets on all my scooters. They helped when you had to order parts down the road. I lost some of the "archived" ones when my garage got a roof leak. I had some good info on Helix parts, what fits what and such. I would find correct size aftermarket clutch springs that engage at a higher RPM. Sand the inside of the clutch bell were the shoes hit and see what happens. I would also track down a "tuning" roller weight kit, makes tuning much easier. Then when you find out what works best, order your permanent weights.

Ok that's what I was going to do when I bought the Dr puller variator kit them just buy cheap weights to find out what weight works best then get the sliders.
I seen the Polini and malossi clutch bells relatively inexpensive so I'd figure get one since it's lighter (not much) then the stock bell. And they're designed for their performance clutches so they "should" hold up better. I've warped clutch bells in the past with too much torque so I've gone with aftermarket ones with stock clutches and just put in springs. The issue I'm now having is finding the parts I want. Not much of a selection out there anymore for the clutch parts. I want springs for the pads and a torque spring.
So if I can get those and see how it rides I might not need to change the rollers. So it all depends on what I can get. I've seen torque springs but it's for a cn250 buggy I think so I don't know the difference if it'll work or not.

Anyone have any luck with buggyparts? Or bought from them? I found this torque spring good price. Says it's for scooter cn250 https://www.buggypartsnw.com/index.p....html?___SID=U


They don't have the clutch springs i want. The only ones I can find say they're for the cn250 malossi on eBay, but the description is in another language or Chinese universal springs. This is getting to be a challenge hahaha.

I've ordered from Buggypartsnw before, good people. If your not 100% sure, email them. they are a real brick and mortar store and will reply. They may be able to help you on clutch springs to. If you order the ebay springs for the clutch, just make sore they are the same size as the ones that are on the scooter. A tighter (higher engagement) spring will be the same size, just a different steel strength. Hope this helps, as I no longer have my old Helix service manual. I had a crazy amount of notes regarding sizes of springs and other "generic" parts that fit. I have another Helix service manual but there are no notes in it. It was a freebee from a old guy.
