Alright lads. Have had tmax's for the last 5 years - needing a bit more punch!

Has anyone fitted a new variator and what are your views?

I've been told that the J Costa gives more performance than the Malossi, I'd be looking to get a J Costa Evo 2 race variator.

Any ideas on where i can get these reliably and what parts other than the variator and the belt if any i need to replace??

All thoughts and views appreciated.

Thanks

Richard

ps, its a MK2 2009 reg.

hi, not sure if funkeycowie has uprated to Dr pulleys on his tmax, he used to run them on the nexus... if you go for the j costa welsh scooter parts sell them for around £340 mark...
or the evo2 new at £299 ish from http://www.easyparts.nl/showarticles_in ... acing.html" onclick="window.open(this.href);return false;

or if you will eventually tune your engine, eg sprint air filter, racing plugs and management system etc go for the evo 3 titanium racing version at £400

to be honest i found that buying Dr Pulleys weights at 20% less than original rollers were as brilliant if not better and at around £45 delivered you could save a packet... buy yourself a new air filter (lasts for life) £35 DONT BUY THERE SPRAY OIL BUY YOUR OWN FOR A £5 http://www.motorcycle-exhausts.co.uk/DN ... -7559.html" onclick="window.open(this.href);return false;
Tried to be objective, cheers

Use ebay italy for less than £250

JCosta makes no monetary sense, pins are £40-50 a go and last about 4000 miles

Get lighter weighted Dr Pulley rollers (15gm) and sliders, they are about £35-40 a go, fit in your original variator and last for over 12000 miles.

Always go for OEM belt they last longer.


As michaelphilips says I have had a JCosta in my Nexus 500 and hated it. I ruined the pins in about 2000 miles, the Athena belt I used slapped against the timing thing too much and worst of all it made it sound like a 50cc moped. I took it off and put the old variator back on with lighter weight Dr Pulleys (28gm - 26gm) and noticed a good difference. With the TMax I have gone even lighter than standard (18gm - 15gm) and she goes like stink without all the fuss of a JCosta.

How about the 560cc conversion

Agree, I bought Lyn's costa and took it out as I didn't like it. The 15g Dr Pulleys were much better.

Michael - Thanks very much! I'll get the pulleys and give that a bash. Failing that R1K i'll give the 560 conversion a go!

One last question - i've seen footage on You tube of a tmax turbo - skip to 51 secs in. Do we know of anyone who could make this happen in the UK?

Glad to hear that. I'm fitting them today!

MjW... What parts did you order?? Could you give me the codes as getting the correct ones out of Dirk is proving a little difficult!!

Would appreciate your help.

Thanks

Can you let us know how the difference feels too? A small report back.

Thanks

Richard
