While i understand the convenience benefit if fitting modern carbs etc doesn't that defeat the purpose of Vintage racing  ??? Why stop there just bolt the TT plastics to an RMZ 450  ;)

In the case of the TT600 the stock twin chamber vacum horror can give some pretty ugly starting, so doing an upgrade is worthwhile. FCR just happens to be the best carb about for $90.

But you know your comment about TT plastics on RMZ may not be as silly as it sounds, there have been a couple of nice bikes built around TT600s upgraded with YZ tank and sub frame/seat.

Yeah its not, I'll paint it black nobody will notice  ;)

Anywayz Bill my TT600 as bit too original to work over with modern placky but its food for thought, certainly a tank reduction and reducing the size of lazy boy that Yamaha fitted would make the bike feel like a whippet.

But then again I remember guys Enduroing them back in the day and they used to go pretty decent.

Hey Mark.com

Did the YFM Grizzly inlet manifold fit straight up? or did it need to be modified?

I raced a couple of years for Yamaha Pitmans in the 80's and Malcolm Pitman built my TT's with a YZ front end and wheels and White Power shock plus he built Kevin Long's TT's as well but he had White Power USD Forks on his TT which he won The News 24 Hour a couple of times. They weren't to bad of an Enduro bike but an excellent mustering bike. My dad had 4 of them until the TTR250 came out,

Yeah, leave the carbs as they unless they are giving you grief...if it ain't broke and all....
A good motor mod is to remove to counter balancer and associated hardware, still the same grunty motor, just revs there noticeably quicker, only notice extra vibrations at idle. And how many of us pro's spend any time there right ;)

Havn't got to fitting it yet..... will let you know.

Planning giving the forks a birthday, mine feel soft as butter so at least YZ springs will go into them. But not a bad thought about a shock change I have same year YZ one in my war chest.
