silicon hoses ...CV4 vs China ?

does anyone know if there are major differences between the CV4 Silicon hoses (at over 100 per set) vs the Ones for sale on ebay from China (at 40 per set )

thanks in advance for any info...

Yeah, the price. I've had no issues with my China hoses.

Good...I bought a set of the red China ones off Ebay a few weeks back and plan on replacing the factory black ones on my 08 TE with 3,700 miles on them when I rebuild the motor later this summer (after I get FAG main bearings from George)

I just got my set from china and nothing seems to match up.... any fitment issues?

Don't forget about Samco's as well. Made in GB, great hoses, run them on all my sportbikes. Everyone else is second to Samcos

Plus you can get them in a number of different colors, including a cool looking camo pattern. Plus they have some trick stainless steel no pinch clamps as well

Silicon is permeates water, but not to ethylene glycol. Over long periods of time, you will end up with heavy ethylene glycol mixtures which do not cool as well.

Preamble? I think you mean permeable.

Time to add a coolant change to my to do list...

More internet/magazine mechanican' Good grief already, find something, ANYTHING for crying out loud, that backs up your claims that DOES NOT come from a party with a vested interest
in the product or data.

Gates hoses on Semi trucks is being used to compare water loss to our bikes? Really? They run 10,000's of thousands of miles BEFORE the mix ratio could become an issue. They said it themselves, driven every day with TWO freakin shifts, that's 16 hours of work every day for a year.

Just want to give you guys a heads up that purchase these cheap Chinese silicone hoses. This is no BS!! I was lucky to not be stranded yesterday!!





These hoses are crap!! You get what you pay for.....

I use these.... http://www.profactoryhoses.com/

Initially bought Samcos since from my auto days they were the hoses to get. Unfortunately the Samco fit was not great so returned them and bought the above products. Fit was good and allowed me to trim to fit perfectly.

Nothing against SAMCO, I run them on my KTM 950.
But on my KTM 525 EXC and on my TE 310R I run the above mentioned pro factory. No issues to report.

Were those the 4 ply Chinese ones?
I've had a set on my 360 for 4 years no issues, mind you I don't clamp them up anything as tight as yours look.

They're orange! What do you expect

Profactory here too. The owner is very helpful and takes calls himself. Highly recommended. No issues

Gplus are the hoses I use and not had any issues yet.

Samco or CV4 well proven on many types of racing vehicles. Go cheap-Go home.
support the sport, support the supporters of the sport.

PS I don't even have water in my coolant anyway!! (Evans Powersport or ZipTy XF2)

Lol

I was hoping Chris would pop back in with some info. I believe he WAS using Evans, and also that he rode 10 miles w/o coolant afterwards- according to this thread on TT:
http://www.thumpertalk.com/topic/1068680-where-did-you-ride/?p=13295473

I gotta ask him (Chris... you there?) about that reading of 316°F on his meter. Wow! Waterless coolant may not vaporize at water temps, but still- I bet the pressure was tremendous.

edit: Chris reports in a TT thread that his plastic impeller was gone except for a few pieces found throughout the cooling system.
