Helix CN250 clutch& sliders By kiwiscoot (Read 2,948 times)

I need some help here fellow scootaholics!!
Opened the Helix's tranny this weekend and the clutch shoes and rollers are shot. I don't think even measuring the rollers will help as they have some significant flat spots. Questions:
1.) what size/weight sliders will make this puppy sing again?
2.) where can I get these plus some replacement shoes for the clutch? To minimise the shipping costs to this outpost of civilisation, if it is possible to get the shoes only, I would like them. The rest of the clutch is still very good.

Your help will be appreciated and I promise to help others in future.

Hi kiwiscoot,

Here is a vendor that sells the clutch shoes and original variator weights:

www.cheapcycleparts.com/model_years/1386-honda-2006-helix-CN250/assemblies/13919

Here's another vendor:

www.monsterscooterparts.com/clutch-weight-set-honda-cn250-2000-2007.html?productid=clutch-weight-set-honda-cn250-2000-2007&channelid=FROOG

Monsterscooterparts.com does ship worldwide.

The stock weights are 23 X 18 mm in size which is what the YY250T with the 244cc engine takes. The weight of the OEM rollers in my YY250T was 24 grams each.

thanks for your help. Need to make a list of what I need to save on shipping costs.

Interesting communication I had with Carlos (aka auto355 of ebay). Apparently the older style (pre-'92??) used a "wet" (greased) variator and used the 23.8X18 (~24) sliders/rollers. After that they used a dry variator and now use 23X18. Guess before jumping for a 24X18 first measure your variator.
Now another interesting thought. Going for a roller/slider that is 1mm bigger will push the belt out further giving higher topspeed with lower rev's. Just as long as the variator has enough clearance at the low end to let the belt sit at the normal low gear position.
At this stage still making up a list of what I need. Cheapcycleparts seem my best option as their parts seem very reasonable and they do not seem to want to make a huge profit out of the shipping cost.

The OEM roller weights that came with my YY250T (Helix clone engine) were 23.5 x 18 mm. I recently got a complete variator set on a good deal and the installed weights were 23.6 x 18 mm. It looks like a true replacement weight (23.5 mm) doesn't exist unless the 23 mm advertised is really a 23.5mm?

I installed 23 x 18 mm sliders with excellent results. If anyone has installed 24mm weights in there 244cc scoot, it would be interesting to hear the results.

I have a couple of stock variators with rollers I dont need,
